QUESTION:

How can we keep scratches to a minimum after using final film?

ANSWER:

We usually request a visual image of one or more scratches as well as geometry measurements of the connectors in order to answer this question.With this information, we try to understand the mechanical parameters applied to the film and connector.This includes various aspects of the entire lapping film operation: the polisher, lapping films, time, pressure, rotation speed, stability, applied fluids, cleaning procedures, and so forth.

Why such a thorough investigation?Because scratches might relate to issues in earlier steps in the assembly process.For example, epoxy application, epoxy mixing and/or outgassing, the curing schedule, and encapsulated humidity are common – and surprising – root causes for seeing scratches with a final film.

Also, the cleaning operation of the lapping films, connectors, and polishing fixture between polishing steps is often detected as a root cause for scratch generation.In fact, so-called "cross-contamination" is common when rough lapping film debris isn't thoroughly removed when starting with a finer grit abrasive film.

(We recommend cost-effective silica carbide abrasive films for excess epoxy removal, followed by a finer grit abrasive film to establish a perfect geometry - contact FOC for more custom and specific film recommendations at (800) 473-4237 / 508-992-6464 or email:sales@www.spnnc.com)
