MEASUREMENTS
Mils and millimeters are often used interchangeably.
1 mil = 1/1000 inch (.001”)
1 mm = .0393 inch
1 inch = 25.4 mm
CONVERSION RULES
❊ To convert millimeters into inches, multiply millimeters by .0393
❊ To convert inches into millimeters, divide inches by .0393
❊ To convert mils into inches, multiply mils by 1000
❊ To convert mils into millimeters, divide mils by 39.3

*Caution: Most SMD components are built to the metric (mm) standard.
Engineers sometimes mistakenly express dimensions by rounding mils.
It is more acute to use 0.65mm instead of 25mils and 0.5mm in place
of 20mils.

PITCH
Lead pitch is always measured from center to center of the leads.
Pitch is never considered the air gap between the leads.

QFP
RECTANGULAR BODY
Quad Flat Packs have gull-wing leads on four sides. The body material is molded
epoxy known as “plastic”.
Ceramic body Quad Flat Packs are also available on special order (CQFP and
CERQUADS).
Most QFPs are square; however, they are also available in a 14mm x 20mm
rectangular package.
TopLine uses the QFP designation; however, the industry may call them MQFP
(Metric Quad Flat Pack).
Standard thickness of QFP is 2.0mm to 3.8mm. For thinner versions, refer to
TQFP and LQFP pages.
The same body size and lead count is usually available with 2 or 3 different lead
length footprint adders.
The footprint adder twice the actual lead length. For example
a 3.9mm adder has 1.95mm leads on each body side.
For example, a 28mm square body with a 3.9mm adder actually measures 31.9mm
from lead tip-to-tip.
Standard packaging is in trays, however, tape and reel is becoming more popular.

BQFP
The BQFP is a version of Quad Flat Pack with corner bumpers to protect the
leads during transport and handling.
The BQFP is no longer popular.
The lead pitch of BQFP is a true 25.0 mils instead of the metric 0.65mm.
Because the lead pitch is not built to metric standards, it is subject to errors in
circuit board design.
The bumpered corners allow BQFPs to be packaged in tubes, however, trays
are more popular. Also available on tape and reel.
31
BGA
The leads of Ball Grid Arrays are actually spherical solder balls.
BGAs offer several advantages over other high lead count devices such as QFP.
ADVANTAGES
1. Solder ball leads are not as fragile as QFP gull wing leads.
2. During soldering, BGA leads are self aligning.
3. BGAs have higher lead count than QFP.
DISADVANTAGES
1. Requires an x-ray machine for inspection of leads after soldering.
BGAs are available with lead pitch of 1.0mm, 1.27mm and 1.5mm.
Ball Grid Arrays are also available in a variety of case materials.

FLIP CHIPS
Flip Chips are die sized components with the bumps attached to the die.
The bumps come in 3-popular materials: Eutectic 63/37 SnPb solder, gold and
nickel.
Eutectic bumps are preferred when mounting the flip chip to FR4 laminate
circuit boards.
Nickel is preferred for soldering to high temperature ceramic substrates
(circuit boards).
Often the bumps are spherical, however, square and rectangular bumps are available.
Flip Chips are quite small since there is no extra packaging covering the die.
The bump pitch is very small and is measured in microns (µm) rather than
millimeters.
1000 (µm) microns = 1 millimeter.
There is no industry standard die size or pitch for flip chips.
Each design is specific to customer applications.
TopLine offers mechanical (dummy) flip chips from open tooled customer
design with daisy chains.
34
CHIP SCALE PACKAGES
Chip Scale Packages (CSP) are a cross between BGAs and Flip Chips.
By definition, the maximum footprint dimension of a Chip Scale Package is no
greater than 1.2 x the die itself.
Different kinds of Chip Scale Packages are being developed.
The most popular (at the time of this writing) is the Tessera µBGA R available in
46 and 188 bumps.
Other manufacturers such as Citizen and FCT have developed unique Chip Scale
designs.

LCC
LCC package was developed in the ‘70’s and still enjoy limited usage
today, particularly for defense, aerospace and high temperature applications.
LCC packages are made of ceramic and are quite rugged.
There are no “leads” to bend or damage.
LCC packages use metalized castellations on four sides of the body which are
solderable to the PC board.
The castellations are usually gold or solder coated.
The pitch of LCC is either 40mils (1.0mm) or 50 mils (1.27mm).
There are well over 100 different lead count, pitch, and body size combinations;
however, the most popular LCCs have 50 mil pitch with lead count and body size
that match standard PLCC plastic packages.
LCC dummy packages are available with and without lids. Lids hermetically seal
the die inside of the LCC cavity. Lids are usually gold plated, but ceramic lids are
also available.
Standard packaging is tubes, trays or simply bulk packed in bags.
40
FLAT PACK
Top
Line
Flat Packs were developed in the late ‘60’s and still enjoy limited usage today,
mainly in military and aerospace applications.
As the name suggests, flat packs have unformed, flat leads which must be protected
in a carrier prior to assembly.
Flat Packs are either ceramic or plastic with either gold plated or solder coated leads.
Depending on the cavity location and case construction, the leads extend either from
the middle, bottom or top side of the body.
SIDE/SANDWICH
CODE S
BOTTOM BRAZED
CODE B
TOP BRAZED
CODE T
The lead pitch of flat packs are usually 50mils (1.27mm).
During construction, the leads are built on lead frames which hold the leads straight.
After excising (cutting) the Flat Pack must be mounted into an individual plastic
carrier to prevent lead damage.
Immediately prior to the assembly, the Flat Pack goes into a lead forming tool
(or machine) which bends the leads into a Gull-wing shape and the excess is cut off.
Flat Packs are used for integrated circuits and resistor networks.
Flat Packs are available with and without lids.
41
TO PACKAGES
TRANSISTOR OUTLINE
Transistor packages are designed by a TO number which is assigned by JEDEC,
a joint industry standards committee.
Leaded (throughhole) TO packages were developed in the early ‘60’s and ‘70’s.
Leaded transistor packages are either metal or plastic.
For example, the TO3, TO5, TO18, TO39 and TO99 are metal.
TO92, TO126 and TO220 are plastic.
SMD transistor packages are only plastic, such as the TO236AB (same as SOT-23)
and TO252 (same as DPAK).
Early designed Integrated Circuits were often placed into multiple lead, metal TO
packages such as the TO99 with 8 leads, the TO75 with 6 leads and the TO100 with
10 leads.
Multiple lead TO packages are usually mounted in a plastic carrier to protect the
leads prior to assembly.
The TO5 and TO99 are still used in military applications.
The TO39 is easily substituted for the TO5, with the only difference being the length
of the leads.
TO39 have shorter leads that TO5 packages. Since the excess lead is always cut
off, either TO39 or TO5 will do the same job.
The TO92 is a low cost, leaded plastic package for commercial use. It is available
either bulk for assembly by hand or tape and reel for machine assembly.
Standard bulk packed TO92 have unformed leads with .05” (1.27mm) pitch
between each lead.
42
TO PACKAGES
(CONT’D)
Most TO92 on tape and reel have the leads formed (prior to taping) with
.1” (2.54mm) pitch between the leads.
Some TO packages such as TO3 and TO220 are available in tubes for machine
assembly.
The standard TO220 has 3 leads, however a 4-lead and 5-lead version is available.

DO PACKAGE
DIODE OUTLINE
Diodes and rectifiers are designated by a DO number which is assigned by
JEDEC, a joint industry standards committee.
Leaded (throughhole) DO packages were developed in the ‘60’s and ‘70’s.
Diodes and rectifiers are fundamentally the same.
By industry convention, diodes are considered low power devices rated below
1.0 AMP and rectifiers are high powered devices rated 1.0 AMP and up.
Popular, low power diodes such as 1N4148 are hermetically sealed in a cylindrical
glass case with axial leads, designated DO35.
Popular rectifiers such as the 1N4001 series and higher lowered zener diodes are
assembled in the DO41 molded plastic case.
Some surface mount diodes/rectifiers have DO designation such as DO215AA
(same as SMBG) and DO214AA (same as SMBJ).
Leaded DO packages are available bulk packed for assembly by hand or on tape and
reel for machine assembly (and lead forming).
44
LEADED RESISTORS
Throughhole resistors have axial leads and are grouped by into size categories
by their power rating
For example, all 1/4 Watt resistors are the same size, regardless of part number.
The industry refers to “1/4 Watt size” as .1” x .25” (.1” diameter by .25” long).
“1/8 Watt size” means .062” x .145”.
The old carbon composition resistor such as the military RC07 and RCR07 is out
of production even though it is still used today for solder practice.
Leaded resistors are available bulk packed for assembly by hand or tape and reel
for machine assembly.
45
POPULAR THROUGHHOLE
FOR
MILITARY
The military and aerospace industries still use component packages which were
designed 20 or even 30 years ago.
This is not surprising when you consider the amount of time some government
projects take to get approved.
Listed below are popular throughhole component packages which are still used by
the military for solder practice and certification of technicians.

MOLDED CASE
SINGLE INLINE PACKAGE
SIP packages are used for resistor networks and some Integrated Circuits.
The lead pitch is .1” (100mils or 2.54mm).
SIP components may be molded or conformally coated, also called dipped
(not to confused with DIP dual inline).
The conformally coated case offers the lowest cost and is the most popular for
commercial use.
Pin counts from 4 to 12 are available; however, 6, 8 and 10-pins are the most popular.
Bulk packaging may be used for hand assembly. Tubes, tape and reel or ammo is
used for machine assembly.
In the case of tape and reel (or ammo packed) only 3 leads are attached to the tape
which must be excised during assembly by the insertion machine.
48
TRAYS
To
pL
ine
ne
pLi
To
TopLine supplies a limited range of trays. Trays are used to protect components
during transportation and assembly. Trays are usually grouped into two categories:
bakable and non-bakable.
Bakable trays may be subjected to maximum temperatures of 150˚C and are suitable
in situations where the parts must be baked prior to assembly.
Component manufacturers recommend that TSOP and BGA
components be baked at 125˚C for 24 hours prior to assembly to remove any
moisture trapped inside the plastic case. Baking eliminates the “popcorn” effect
of cracking.
Also, components may be “burned in” prior to assembly to weed out potentially
defective components.
Unless specifically requested by the customer, TopLine will supply non-bakable
trays.
Most JEDEC standard trays are 136mm x 316mm (about 5.375” x 12.5”).
It is recommended that a cover tray (most trays are stackable and interlocking,
so the cover tray is just a regular tray) always be placed on top of the stack of trays.
The stack must be bound tightly with heavy-duty rubber bands or velcro straps.
As extra precaution, the stack of trays should be vacuum sealed in moisture-barrier
ESD bags.
Even exercising the above precautionary steps, it is possible for trays to separate just
enough during rough handling to allow the components to shift off their protective
pedestals inside the tray cavities, causing damage to the leads.

TUBES
Tubes (sometimes called sticks or magazines) hold PLCC, SOIC, DIP, SIP and LCC
components.
Tubes are approximately 20” long (500mm), but may range from 18” to 23”
Rubber-end plugs or plastic push-in pins prevent the components from falling out of
the tube during transit.
During assembly, the components are gravity-fed by positioning the tube vertically or
at a steep incline.
The machine often vibrates the tube to assure the components fall out at even speed.
The interior of the tube is designed to conform to the shape of the component without
causing lead damage.
It is quite common to see the same component type (example: PLCC20) be packaged
in various tube quantities (example: 46, 47, 48, 49 or 50), based on the actual length
of the tube and the type of end plug used.
51
CT REEL
EMPTY CARRIER TAPE
TopLine offers a wide selection of empty carrier tape on 7-inch and 13-inch reels for
applications not requiring filled components.
CT Reels have a sealed cover tape.
CT reels are a low cost solution to perform “dry” machine runs without the need to
pick up and remove components from the carrier tape.

ON TAPE AND REEL
Both axial and radial lead components may be packaged on tape and reel.
The reel is constructed with 14~15 inch (355~380mm) cardboard flanges mounted
to a cardboard, hollow code, tubular hub. A metal insert holds the flanges to the hub.
The flanges may be circular or octagon shaped.
Axial lead components are mounted between two continuous strips
of adhesive tape.
Radial lead components are mounted to a continuous cardboard strip and held in
place by an adhesive tape.
The insertion machine will cut (excise) the leads from the tape and form the leads
(if necessary) prior to assembly into holes on the PC board.
54
COPLANARITY
Layman’s description: Think of sitting on a wobbly stool or at a wobbly table
which rocks because all the legs don’t touch the floor at the same time. The amount
of gap between the floor (PC board) and the leg (component lead) is called
coplanarity.
Technical definition: a setting plane formed by the first 3-leads touching the
surface. All other leads are measured from this plane.
To assure good solderability, the maximum coplanarity allowance must be as small
as possible. For example, most QFP components have a maximum guaranteed
coplanarity of 4 mils (0.1mm). This means that no lead on the QFP will be more
than 4 mils (0.1mm) off the PCB (about the thickness of a single sheet of paper).
55
DAISY CHAIN
DAISY CHAIN ODD
DAISY CHAIN EVEN
Continuity testing requires dummy components to contain internal daisy-chain
connections.
Daisy Chaining is also known as stitching.
For QFP, SOIC, PLCC, LCC and TSOP type components, the daisy-chain is
wire-bounding of the leads inside of the component.
For BGA components, the daisy chain is usually made on the substrate.
The standard daisy chain pattern for non-BGA Integrated Circuits is “EVEN”,
designated by a DE suffix at the end of TopLine’s part number (example
PLCC68M-DE).
Daisy chain “ODD” is available on special order with part number suffix DO
(example PLCC68M-DO).
There is no industry standard daisy chain pattern for BGA, Chip Scale and Flip Chip
components.
TopLine has open tooled daisy chain patterns for BGA components which are fully
described in the BGA Daisy Chain Pattern Book, now available on TopLine’s
website at http://www.toplinedummy.com/bgabooklet.pdf.

PRACTICE KITS
TopLine offers a family of over 50 different placement and solder practice kits for all
skill levels - from beginner to the most advanced.
Kits are convenient and include PC boards plus enough dummy components to
populate one side of the PC board.
Most TopLine PC Boards are double-sided, allowing the second side to extend the
usefulness of the kit.
There are two categories of kits:
1.
Hand Assembled Kits
2.
Machine Assembled Kits
Hand Assembled Kits include bulk or singularly packed components in carriers to
protect the leads from damage.
Machine Assembled Kits have components which are mounted on tape and reel, in
trays or tubes
Unless specified by the customer, Machine Run Kits predominately include
components on tape and reel. Customers preferring components in tubes or in trays
are encouraged to clearly state their requirements.
Gerber files and parts placement data are offered as an accessory on 3.5” floppy
diskettes
60
PC BOARD STANDARDS
Unless otherwise stated in TopLine’s Kit Catalog, most kit PC Boards conform to the
following specifications:
Board Material: FR4 epoxy class laminate
Board Size: 5.5 x 4 inch (140mm x 100mm)
Layers: Double-sided with 2-front sides, eliminating the need for separate front and
back stencils.
Metalization: 1-ounce copper
Board Thickness: .062-inch (1.5mm)
Solder Mask: Green LPI (Liquid Photoimageable)
Silk Screen: White ink nomenclature
Tinning: HASL (Hot Air Soldering Level)
Tool Holes: .125-inch (3.0mm) in 4-places
Fiducial Marks: SMEMA (metalized circle with solder mask clearance)
61
PC BOARD MATERIAL
PC Boards are sometimes called substrates and are available as rigid or flexible.
I. Rigid Substrates
A. Laminate Material
1. FR4 epoxy glass is the industry’s most popular laminate for construction
of PC Boards for commercial use. TopLine uses FR4 boards in most kits
2. Polyimide is a high temperature material which is available on a special
order basis. Polyimide is used for applications requiring high
temperatures for extended periods of time. (example: burn-in)
B. Ceramic Substrate: A limited number of TopLine boards are ceramic.
Ceramic affords long life to high heat; however, ceramic substrates are
expensive and brittle.
II. Flexible Boards: Flex boards are made from very thin laminate material and are
used in applications where the circuit must conform around corners of a case
(such as inside camcorders).
Currently, TopLine has no kits offering flexible PC Boards.
62
PC BOARD FINISHING
HASL: TopLine uses Hot Air Soldering Leveling (HASL) on most PC boards.
The HASL process gives boards a controlled plating flatness which assures
coplanarity for fine-pitch components.
Bare Copper: On special order basis, TopLine will supply PC Boards with the bare
copper protected by an OSP covering (Organic Solderability
Preserative) such as Entek. Bare copper offers the flatest surface.
OSP is a clear protective coating which delays bare copper for
approximately 6-months, prior to assembly. It is recommended that
assembly be completed within 24 hour after commencing, since
soldering will disolve the OSP covering.
Gold: TopLine offers a limited selection of PC Boards with gold plating.
Gold offers flatness as well as long shelf life. However, gold
is more expensive than HASL and should only be used if absolutely
required.
63
SOLDER MASK
TopLine uses green LPI (liquid photoimageable) solder mask on most boards.
Solder mask is used to protect circuitry (tracings) on the PC board and reduce
solder bridging during assembly and rework. Solder mask covers all surfaces of
the board including the area between the pads too.
On a special order basis, TopLine can supply solder mask in different colors.
While solder mask is aesthetically appealing, it is not required on throughhole
boards.
Without solder mask, FR4 epoxy glass PC Boards are milky white in color.
64
PLATED THROUGHHOLE
TopLine uses plated throughholes for mixed technology and boards requiring leaded
components. The inside and top/bottom rim of the hole is plated with solder.
Plated Throughholes ensure a good solder connection of the component’s lead.
Plated Throughholes are also used to connect the circuitry on the top side of the
PC Board to the circuitry on the bottom side.

FIDUCIAL MARKS
Fiducial marks are used by vision equipment to locate the component’s centroid
position on the PC Board.
There are over 10 different fiducial patterns used in the industry, including round,
donut, square, diamond, binary cross, triangle, etc.
Not all vision equipment are able to recognize all fiducial patterns.
The SMEMA (Surface Mount Equipment Manufacturer Association) standard
(solid metalized circle within a solder mask clearance) is used on most TopLine
PC Boards.

66
GLOBAL FIDUCIALS
Layman’s Definition: Think of global fiducials as two fixed points (such as light
houses) to guide ships into port. From these two known points, vision equipment
are able to determine locations on a PC Board.
Technical Explanation: A minimum of two global fiducials are provided for
correction of translational offsets (x and y positions) and rotational offsets
(theta on z-axis) located diagonally opposed as far apart as possible on the
PC Board or panel.
67
LOCAL FIDUCIALS
Local fiducials are typically located at the centroid of an individual component on
the PC Board.
Typically, only fine-pitch components such as QFP and TSOP require local fiducial
marks on the PC Board.
68
GERBER DATA
Gerber is a machine language for designing and fabricating PC Boards.
A typical single-sided PC Board requires the following layers of instruction:
1.
2.
3.
4.
5.
Metalization (copper pads and circuitry)
Silkscreen Nomenclature
Solder Mask
Routing (cutting)
Drilling Hole Locations
Double-sided boards require twice as many instructions for the front and back side.
Multilayer boards require additional instructions.
TopLine provides Gerber Data on 3.5” floppy disks only for the metalization layer
to allow fabrication of solder paste stencils.
TopLine is also able to send the Gerber Data by e-mail in zip format (requires
WinZip to decompress).
CAUTION: The Gerber Data must match the latest TopLinePC Board Revision.

Parts placement data for X, Y and theta coordinates are provided in ASCII format
on 3.5” floppy disk.
These coordinates instruct pick and place machines where to place the component on
the PC Board. Theta θ is the rotation required on the Z axis.
Measurements on the X and Y axis are in relationship to the center of the lower
left tooling hole on the TopLine PC Board.
For example, if a component is to be placed 1.25” east and 2.50” north of the
lower-left tooling hole, the X-coordinate is 1250mils and the Y-coordinate is
2500mils.
Y=2500

STENCILS
Stencils are used to spread solder paste on the PC Board.
Stencils are metal plates with apertures (openings) that match the metalization layer
(pads) on the PC Board.
Solder paste is pushed through the aperture with a squeegee. Automatic machines
are called stencil printers or screen printers.
The stencil is fabricated using the same Gerber Data as used to fabricate the
metalization layer of the PC Board.
Small corrections to the aperature are made, depending on the size of the pad, pitch
of the component and thickness of the stencil plate.
Aperatures on the metal plate are created by chemically etching or laser cutting the
metal plate.
The stencil plate is mounted in on frame according to the type of machine used.
TopLine provides a Metal Mask Stencil Questionnaire which must be completed
prior to ordering stencils.
The questionnaire is used to instruct the stencil manufacturer how to build and mount
the stencil.

INTRODUCTION TO ESD
ELECTROSTATIC DISCHARGE
Layman’s explanation - Think of static electricity as non-moving electrons waiting
for an opportunity to arc to ground. When static electricity arcs to ground we see and
feel it as a “spark”.
Static electricity will destroy “live” semiconductor components such as integrated
circuits and computer modules, etc.
During storage, sensitive electronic components are protected from static in tubes,
tape and reel or in trays.
Precautions on the production floor must be taken to assure that static electricity is
safely grounded to prevent damage to live components.
For example workers should wear grounding wrist straps, heel grounders in
their shoes, and work at ESD safe work stations with static dissapative flooring, etc.

RESISTIVITY
Electrons flow faster through metalic conductive surfaces but slower through
insulative materials.
Resistivity is measured in Ohms.
Metals, such as copper and aluminum, have near zero Ohm of resistivity, so
electrons flow very quickly.
Certain conductive materials such as carbonized plastics have 100KΩ to 1 MΩ
resistivity.
Antistatic plastic materials have 1,000MΩ resistivity.
79
UNITS OF RESISTIVITY
Resistivity is measured in Ohms.
As the number of zeros increase, it is more conveinient to express ohms in
scientific notation.
