unless of course, it can be proved that the coating sticks to the uncleaned board and shows no defects as per IPC specs....but it doubt it

PVA Conformal Coat is well supported throughout the world. If you need software (Pathmaster), spare parts or technical advice, just let me know. EMAIL: jr@hrltd.com.au

How is everyone coating under these connectors? Is RTV covering the outside so nothing can get in an answer? Or very thin silicone to wick under... http://img302.imageshack.us/img302/1728/dscn24450ac.jpg

Does anyone know of a source to get an existing stainles solder pot coated to handle Pb free?

Options are: * Find a low residue flux and conformal coating material that are compatable, so that cleaning is not required. * Use a cleanable low residue flux, clean according to the supplier's recommendations, and then coat boards.

Good idea, pick the most difficult of your PCB and watch the final result. If you can, go to each company and watch the machine how it coats your board. You'll see what is the most suitable for you.

We have a PVA conformal coating machine that is working good for us. you might also want to give them a try. just my 2 cents worth...not associated with PVA in any way

Is there a preferred/efficient method(s)(e.g. tape/masking compounds, boots etc.) for masking off specific areas and/or components on a pwb prior to conformal coating?

Amol, good call there. Silicone mask and silicone coatings are friendly with each other. This was 1995, and at the time, there were no silicone boots available on the market.

First of all, do not use kapton tape! It tends to cause a dewetting effect around the tape. A call to Humiseal will explain why. There's not really a blanket answer to your question.... Removing cured liquid mask can often result in a fillet ef
