Hi

Can any one tell me what the advantages/disadvantages of Parylene coating ? Also is it recommended this process be done in house or sub contracted?

Thanks

Parylene coating is done in vacuum curing chambers. This process drives the material under components and into all nooks and crannies. There is nowhere on the board assembly that can escape from the material! I've only seen Parylene coating process used by military contractors doing Naval/Aero gear. It is an expensive process to put together due to the equipment. For that reason outsourcing is right for many. For more info, go to http://www.scscookson.com/
