Product Feature And Application
Specifying the thickness of solder resist layer can improve electrical insulating properties, and reduce the risk of pelling or loss of adhesion to the strengthen the ability to against the wherever mechanical impact force. Thin solder can lead to adhesion, hardness and resistance to anti-flux problem. All of these issues can result in solder resist layer seperated from the printed circuit board, and eventually lead to corrosion of the copper circuit. and also cause poor insulation properties.
Besides the yellow cover film, this board also uses the yellow solder mask at the dense PAD area. At he bottom of dense PAD area, the metal stiffener is needed, in order to facilitate the assembly.
FAQ
● Q: What is your testing policy and how you control the quality?
A: For sample, usually tested by flying probe; for PCB Volume over 3 square meters, usually tested by fixture, this will be more faster. Due to there’s many steps to PCB production, we usually do inspection after every step.
● Q: What kinds of quality Raw Materials will be used?
A: We use top raw materials as below, ensuring product quality from the source.
