Hi, i'm facing solder mask peel off but limited to the solder defined pad only(opening area). no peel off on the other area and it happened on electroless nickel immersion gold finishing only. for other finishing is not affected. kindly advise if you

Yes, a polite complaint to our board shop later and the next batch didn't have that problem at least. I'm not convinced it's an ENIG issue as there was variability panel to panel in the first place.

Today's consumer electronic product are characterized by miniatuization, portability and light weight with high performance, especially for 3G mobile products. In the future more fine pitch CSPs (0.4mm) component will be required. However, the product reliability has been a big challenge with the fine pitch CSP. Firstly, the fine pitch CSPs are with smaller solder balls of 0.25mm diameter or even smaller. The small solder ball and pad size do weaken the solder connection and the adhesion of the pad and substrate, thus the pad will peel off easily from the PCB substrate. In addition, miniature solder joint reduce the strength during mechanical vibration, thermal shock, fatigue failure, etc. Secondly, applying sufficient solder paste evenly on the small pad of the CSP is difficult because stencil opening is only 0.25mm or less. This issue can be solved using the high end type of stencil such as Electroforming which will increase the cost.
