See Appendix for data sheet on Rogers 3003 materials and solder.
3 MANUFACTURING
3.1 BOARD CONSTRUCTION
The following assembly instructions should be provided to the circuit-board house:
i) board material is Rogers RO3003,
ii) no silk screen, no solder mask,
iii) finish is electrolytic gold (hard gold).
3.2 PCB ASSEMBLY
A lead-free solder based on tin/silver/copper has to be used (see section 2). All parts and the entire
assembly process should follow lead-free guidelines.

LIGO-T060280-00
4 CLEANING
4.1 STEP 1: FLUX REMOVAL
A cleaning step to remove any remaining flux. Use an ultrasonic cleaner set to 50°C and immerse
for 1 hour in an aqueous flux remover. The required flux remover is Chemtronics ES132 (FluxOff® Aqueous Flux Remover) which should be diluted with de-ionized water at a ratio of 1:10.
See the appendix for data sheet and MSDS. After cleaning, rinse assembled PCB in de-ionized
water and let dry.
4.2 STEP 2: BAKING PREP
A cleaning step to prepare for baking. The assembled PCB should be immersed in isopropyl
alcohol for 30 minutes using an ultrasonic cleaner. After cleaning, rinse assembled PCB in deionized water and let dry. One can use a heat lamp at ~85°C to accelerate the drying process.
4.3 STEP 3: BAKE
The bake temperature should be as high as allowed by the used components. The materials in
section 2 easily allow for 150°C. Additional components should be selected to allow for the same
temperature or for at least 120°C. The assembled PCB should be at temperature for 48 hours. All
applicable vacuum bake procedures have to be followed (RGA scan, packaging, etc.).

The world runs better with Rogers.™
RO3000® High Frequency Circuit Materials are
ceramic- filled PTFE composites intended for use in
commercial microwave and RF applications. This
family of products was designed to offer exceptional
electrical and mechanical stability at competitive
prices.
RO3000® series laminates are PTFE-based circuit
materials with mechanical properties that are
consistant regardless of the dielectric constant
selected. This allows the designer to develop
multilayer board designs that use different dielectric
constant materials for individual layers, without
encountering warpage or reliability problems.
The dielectric constant versus temperature of
RO3000 series materials is very stable (Charts 1 and
2). These materials exhibit a coefficient of thermal
expansion (CTE) in the X and Y axis of 17 ppm/oC.
This expansion coefficient is matched to that of
copper, which allows the material to exhibit
excellent dimensional stability, with typical etch
shrinkage (after etch and bake) of less than 0.5 mils
per inch. The Z-axis CTE is 24 ppm/ C, which provides
exceptional plated through-hole reliability, even in
severe thermal environments.
RO3000® series laminates can be fabricated into
printed circuit boards using standard PTFE circuit
board processing techniques, with minor
modifications as described in the application note
“Fabrication Guidelines for RO3000® Series High
Frequency Circuit Materials.”
Available claddings are ½ , 1 or 2 oz./ft2 (17, 35, 70
µm thick) electrodeposited copper foil.
RO3000® laminates are manufactured under an ISO
9002 certified system.
Chart 1: RO3003™ Laminate Dielectric Constant vs. Temperature
The data in Chart 1 demonstrates the excellent stability of
dielectric constant over
temperature for RO3003®
laminates, including the
elimination of the step change
in dielectric constant, which
occurs near room temperature
with PTFE glass materials.
Chart 2: RO3006™ and RO3010™ Laminate Dielectric Constant vs. Temperature
The data in Chart 2 shows the
change in dielectric constant
vs. temperature for RO3006®
and RO3010® laminates. These
materials exhibit significant
improvement in temperature
stability of dielectric constant
when compared to other high
dielectric constant PTFE
laminates.
Chart 3: Dielectric Constant vs. Frequency for RO3000® Series Laminate
Chart 3 demonstrates the
stability of dielectric constant
for RO3000® series products
over frequency. This stability
simplifies the design of broadband components as well as
allowing the materials to be
used in a wide range of
applications over a very broad
range of frequencies.
The data in Charts 1, 2 and 3 was produced using a modified IPC-TM-650, 2.5.5.5 method. For additional information request Rogers
T.R. 5156 and T.M. 4924.

Product Description
Reliability Properties
Kester 275 No-Clean Flux for cored solder wire
was developed to provide superior wetting
performance for hand soldering in the electronics
industry. The chemistry is based on some of the
same principles that have been safely used for
years in mildly activated rosin fluxes. The use of
275 No-Clean Flux results in an extremely clear
post-soldering residue without cleaning. The
unique chemistry in Kester 275 was also designed
to reduce spattering common to most core fluxes.
Kester 275 can be used for both lead bearing and
lead-free soldering.

Application Notes
Availability:
Kester 275 is available in a wide variety of alloys, wire diameters and flux percentages. For most applications,
Sn63Pb37or Sn96.5Ag3.0Cu0.5 is used. Consult the alloy temperature chart in Kester’s product catalog for
a comprehensive alloy list. The standard wire diameter for most applications is 1.00mm (0.031in). Wire
diameters range from 0.25 - 6.00mm (0.010 to 0.250in). A "Standard Wire Diameters" chart also is also
included in Kester’s product catalog. The amount of flux in the wire dictates the ease of soldering for an
application. For tin/lead applications, core 50 or 58 (1.1 and 2.2% flux by weight) are recommended. For
Lead-free and high-lead applications, core 58 or 66 (2.2 and 3.3% flux by weight) are recommended. Kester
275 is packaged on spools of different sizes to accommodate a variety of applications.
Process Considerations:
Solder iron tip temperatures are most commonly between 315-371°C (600-700°F) for Sn63Pb37 and
Sn62Pb36Ag02 alloys and 371-427°C (700-800°F) for lead-free alloys. Heat both the land area and
component lead to be soldered with the iron prior to adding Kester 275 cored wire. Apply the solder wire to
the land area or component lead. Do not apply the wire directly to the soldering iron tip. If needed, Kester
959T no clean, liquid flux may be used as a compatible flux to aid in reworking soldered joints. Kester 959T
is also available in Flux-Pens® for optimum board cleanliness.
Cleaning:
The 275 residues are non-conductive, non-corrosive and do not require removal in most applications. The
flux residues are comparable to a conventional RMA except that the 275 residue is clear and colorless. If
residue removal is required, call Kester Technical Support.
Storage, Handling, and Shelf Life:
Storage must be in a dry, non-corrosive environment. The surface may lose its shine and appear a dull
shade of grey. This is a surface phenomena and is not detrimental to product functionality. Flux cored solder
wire has a limited shelf life determined by the alloy used in the wire. For alloys containing > 70% lead, the
shelf life is two years from date of manufacture. Other alloys have a shelf life of three years from date of
manufacture.
Health & Safety:
This product, during handling or use, may be hazardous to health or the evironment. Read the Material
Safety Data Sheet and warning label before using this product.
