BGA underfill necessary with conformal coat?

Electronics Forum | Wed Mar 27 18:23:01 EST 2002 | kmorris

Does anyone have experience doing conformal coating over Plastic BGA in High-Rel PCB assembly? Is underfill necessary to avoid problems with entrapped air, etc? Our application is a 17x17mm BGA, 256 I/O. We are assembling with a water soluable pas

Dear All, In order to understand the soldering technologies in SMT, I'd like to understand why some cards are soldered and then cleaned, or only soldered whitout water cleaning nor "ultra sound" wavelength. I mean that I wonder why we use

Bubbles and Conformal Coating

">ASYMTEK Products | https://www.nordson.com/en/divisions/asymtek/your-process/applications-corner/bubbles-and-conformal-coating

  Bubbles occur when solvents or air become trapped and can’t escape conformal coating material. The presence of bubbles can lead to long-term product reliability issues including bridging of conductive paths, corrosion of exposed areas, and cracked coating due to temperature changes, shock or vibration
