Conformal Coating Bubbles One of the major causes for failure during conformal coating inspection are bubbles. Bubbles are trapped pockets of air under coating. The bubbles can cause voids in the coating and Here we will identify the six largest causes of bubbles.
NASA-STD 8739.1 is the Workmanship Standard for Polymeric Application on Electronic Assemblies, which describes NASA’s technical requirements, procedures, and documenting requirements for staking, conformal coating, bonding, and encapsulation of printed wiring boards and electronic assemblies. Included are requirements which establish the responsibility for documenting, fabrication, and inspec
