Apply the Solder Masking Properly Any areas of the PCB which do not require soldering have a solder mask placed as its top layer. Molten solder won’t stick to epoxy, which is a common type of mask material. Therefore, you have to apply that mask in-between the component pins so as to...
3M 2090 Equivalent GBS Crepe Paper Masking Tape for Car Painting GBS Blue Masking Tape (equivalent to 3M2090) is made of crepe paper as substrate with rubber/silicon pressure sensitive adhesive, which is high temperature tape and is the best masking tape choice f...
The PCB acts as the cathode while an anode is used to electrolyze the liquid solder mask solution. This deposits a thin even coating of the mask uniformly across the PCB surface. The mask is then cured by heating to finalize the coating. ...
David is President at R&D Technical Services, a vapor phase reflow oven manufacturer. he has 20 plus years experience in the vapor phase reflow industry. I would need to see samples to be sure, but I would bet that the solder balls are forming because the solder in the joints is being ...

Solder mask and silkscreen: get the must-knows Download Now Why is a conformal coating used? Conformal coating can perform the following functions: The coating offers high insulation protection, resulting in closer conductor spacing. It acts as a resistant barrier to moisture and humidity, reducing...
Finally, a solder mask is applied to protect against oxidation and solder bridge formation.The Future of PCBs As the backbone of modern electronics, PCBs will continue to evolve as the devices and machines they power continue to get smaller, more flexible, and more powerful. Miniaturization, alon...
easier to weld. 3. In the PCB proofing process, both nickel-gold electroplating and immersion gold are surface treatment processes. The difference is that nickel-gold electroplating is done before solder masking; while immersion gold is done after soldering masking. Hope the above knowledge can pro...
I've noticed that solder joints can start to corrode, and recently moisture made it under the solder mask on a board and actually ate through one of the traces, breaking the circuit. I know the ideal answer is to make a perfectly sealed enclosure, but I'd li...
