These assemblies have a silicone based conformal coating. During repair some of the coating is removed. After repair our tech uses an acrylic conformal coat to touch up the area. Could there be a compatibility problem, particularly with adhesion, when we mix these two coatings? Board Talk Conformal Coating Over No-clean Flux Is it normally acceptable to apply conformal coating directly over circuit boards assembled with no clean flux? Board Talk Conformal Coating in Nitrogen Environment We operate a conformal coat machine using nitrogen. We are thinking of changing it back to air for cost reasons, what are the pros and cons? Ask the Experts What Causes Solder Mask Outgassing? Industry expert Bob Willis explains solder mask outgassing defects with the help of the NPL Defect Database. Production Floor When To Use Adhesive To Bond SMT Components When should we use adhesive to bond SMT components to the bottom-side of a double-sided PWA before going through reflow soldering? Board Talk Lower Temperature Solder Joint Encapsulant The strength of solder joints is enhanced by several times, and thermal cycling performance is significantly improved. Materials Tech Measuring Conformal Coating Adhesion Coating adhesion has been a difficult property to measure. This paper reviews a new tape peel test that can be applied to the PCB or component surface. Materials Tech Reliability of Coated WLCSP Components Paper evaluates coating adhesion and solder joint reliability for assemblies with different conformal coatings, solder masks and underfill. Analysis Lab Thermally, Electrically Conductive Adhesive to Control Heat in PCBs Study illustrates the complexity of achieving optimum thermal and electrical performance with any circuit, especially at higher frequencies. Materials Tech Process Optimization for Fine Feature Solder Paste Dispensing In this paper the authors evaluate variables in the solder paste dispensing process, and review the impact on dispense quality of the solder paste.
