| I have boards coated with Humiseal 1B73. At a late point mfg. site we need to remove a series of 0603 resistors for optioning purposes. I have been trying to determine the fastest, easiest way to re-coat the pads after removal. Drying time of the coating will slow up production on the line. Does anyone know of a substance, possibly a pen type applicator, which dries within seconds and is non-conductive? | LeeAnne,
1B73 brush applied should cure tack free within 15 minutes. If the operator is doing this job under a UV light and ventilated booth, then the production could be "batched" with many coated and left drying within a short time frame? Could that suit you?
Please bear in mind that using a different coating type to the original, will compromise MIL Spec qualification which may be important.
Using a fundamentally different coating, such as a UV, will influence flexibility and may well give you TCE mismatch.
If there is anything else I can help with, call me
