Overview of Practices for Installing the Cleaning Polymer
Probe Clean®, Probe Polish®, Probe Scrub®, and Probe Lap® engineered polymerbased materials manufactured by International Test Solutions are designed to
remove loose debris and adherent materials which are generated during probing.
For typical field installation, a semi-rigid polyester film is used in the construction
of the polymer.

The instructions are meant to be general guidelines and each user can have slightly
different practices; however, these practices should follow the overall procedures.

Latex gloves
Lint free clean room clothes
Firm foam rubber roller
Cleaning polymer with front and back release liner
Stereo Microscope for inspection of the polymer edges after cutting (optional)
Prober substrate, abrasion plate, EZ-planar block, cleaning unit, or WAPP
(wide area polishing plate) onto which the cleaning polymer material has been
previously installed.
Liquid alcohol (preferably IPA), greater than 99.5% pure, anhydrous, meets
SEMI base spec standards, and is labeled “electronic grade”

PROBE POLISH®
After repeated use, the polymer surface will also accumulate a substantial amount
of debris as well as various air-borne particulates, such as dust, skin, etc., found
within a prober. Once the surface has been fully utilized, the material can be easily
removed by peeling the polymer from the surface.

CAUTION: To avoid contaminating the adhesive, surface of the cleaning
polymer or the substrate, latex gloves are recommended when handling
all materials. Polymer working surface (probe side) contamination due
to fingerprints and exposure to unapproved materials and chemicals
will void any warranty.
Once the surface onto which the polymer is to be installed has been thoroughly
cleaned, the polymer films can be replaced according to the general instructions
outlined below.
METHOD
•

•
•
Clean the surface of the plate (or substrate) thoroughly with Semi-Grade IPA
using a clean-room, lint free cloth and allow the surface to dry completely.
Inspect the surface carefully and make sure that there are no liquid droplets,
dust particles, or any sort of other debris visible across the surface.
Partially remove the back release liner from the ITS Probe Cleaning Material
sheet along one edge to expose the backside adhesive as shown in Figure 1.
Carefully align edge of exposed backside adhesive along the desired starting
location on the substrate, abrasion plate, EZ-planar block, cleaning unit, or
WAPP (wide area polishing plate) as shown in Figure 2.

Figure 1 – Remove back release liner as
indicated by label applied to surface.
Figure 2 – Align edge along desired
starting location.
Gently and uniformly apply the material onto the substrate using a firm foam
rubber roller (as shown in Figure 3) while SIMULTANEOUSLY removing the
back release liner (Figure 4).
This can be quite tricky in the beginning and will require some practice.

POLYMER INSTALLATION

the material onto the substrate using a

Figure 4 – SIMULTANEOUSLY removing
the back release liner while rolling the
material onto the plate or substrate.
Move very slowly and carefully to avoid capturing any air or debris between the
adhesive layer and the substrate.

Working slowly and methodically, carefully apply the material to the plate until
the back release liner has been removed (Figure 5).

the edges to confirm that they are free
of tears, shredded material, trim debris,
or any discontinuities.

If using oversized material, very carefully trim any excess material using a very
sharp razor blade.
Perform a carefully and thorough visual inspection using the naked eye and
stereo microscope, as appropriate, of the polymer working surface for smoothness, i.e., no surface “bumps” or airbubbles beneath the surface are visible.
IMPORTANT
The polymer material can be generally applied ONLY ONCE without damaging the
backside adhesive or affecting the tack strength of the adhesive. The material typically cannot be pulled back multiple times without compromising either the backside
adhesive, creating creases in the working surface, or the damaging the cleaning
polymer. If the polymer is pulled back, it is possible that the material will delaminate
during usage, surface ridges could form, and could damage the probe card.
Once the installation has been completed and the substrate, abrasion plate, EZplanar block, cleaning unit, or WAPP (wide area polishing plate) is ready for on-line
usage. Install the substrate with the cleaning material applied into the appropriate
location of the prober
Once the cleaning has been installed, remove the polymer working surface front
release liner per the instructions on the release liner label prior to use (Figure 7
and Figure 8). If the front release liner is not removed, the probe card could be
catastrophically damaged during the first cleaning cycle.

For manual entry of the install height into the prober settings, please reference
the values documented on the label applied to the front release liner; otherwise,
refer to the ITS website (www.inttest.net) for the appropriate installed stack height
documentation.
