Electrochemical migration under conformal coating: That's possible. Very few conformal coatings are water resistant. So, if you have ionic material on your board, standback. Uncured material under several IC: Materials like yours need moisture fro

Hi folks, I have a conformal coating application where I need the coating to be UV stable for a number of years without any crazing or cracking of the coating. I have looked for such a coating and have come up empty handed. Much of the circuit boar

Terry, I've never had to deal with conformal coating but I do know that automotive parts manufacturers do a great deal of CC. These are the people that I would be looking to for your answers. Particularly in regard to long term reliability, extreme c

It's weird that it would be just 0805. When we see this it relates to a single part number and it goes way after a time. We use a Humiseal 1B73. I've emailed you the contact for a person that is very knowledgeable on conformal coatings.

We have PVA 354Bench top conformal coating machine. We are going to procure the Humiseal 1B31 material. Is this material is suitable for this model of machine? Is there any special pecautions to be taken while programming? What are the main problemsd

Normally, some conformal coatings do not have very good wetting properties, that should be basic function of a good coating material (the same reqirement as avoid bubbles during coating process)! For UV curing conformal coatings, you can try Lackwe

The environment essentially defines the need for coating. "Inside" may mean inside a men's locker room with attendant high humidity or inside a climate-controlled clean environment. Conformal coatings offer protection against moisture, fungus, chemi

We are producing boards with Alpha 591S RMA No-Clean paste and are coating after SMC with Dow silicone ( toluene solvent based) conformal coating. We have experienced several failures due to soft shorts ( electrochemical migration?) We have also obse
