In this issue Nexus reviews subcontract conformal coating services provided by coating houses and the problems faced today. If you want to subcontract out then read this article. Nexus is also looking closer at conformal coating defects related to the IPC Standards and why they occur? The technical article Who Do Defects Occur? gives some insight into how to solve most of the main issues that can stop the line and cause a lot of heartache.
Also, we are introducing a new section at Nexus this month called Conformal Coating101. This section answers all the questions about why we use coating, what it does etc and answers many of the questions we are regularly asked.
Finally, Nexus starts its Conformal Coating Workshop Program off in October and November in China and India, respectively and we confirm further dates for North America and Europe in the New Year.

“One of the biggest issues we face is availability of the materials. As a subcontract coating house we generally have to use the coating selected by the customer. This can have dramatic issues occasionally when lead times on products can stretch into weeks or months and the customer wants the product now!”
“Conformal coating is one of the last processes on the PCB. Coating houses are normally making up the time lost in other areas. If you can plan the production to coincide with the material supply chain it’s a great help!”
“One of the interesting points is not all conformal coating defects and problems show up under UV light. You really need to inspect your PCB under white light and UV light to check for different defects. What can look like a perfect coating under UV can cosmetically look awful under normal daylight!”
“Also, you cannot tell how good coating adhesion is with visual inspection only. We examine the PCB as a coating service and if it looks good that’s fine. but without testing we cannot tell how well the conformal coating has adhered.”
The next Nexus Newsletter will be published in the middle of September. Covered within the issue will be articles including:
Main Feature – Subcontract Conformal Coating Services – A necessary evil or the ideal solution.
Technical Article – So you are considering outsourcing – What does that really cost?
Ask the Experts – Users and suppliers of subcontract service explain their viewpoint on challenges found in contract coating.
