Hello there, Most probably, since the solder balls are entrapped, it is a process indicator, but refer to IPC 610-6.5.3.1 on Excess solder / solder balls / splashes - it really depends on what class you are manufacturing, and the minimum electrical c

I have been having the same problem with the LLP. I have three stencil I have done reduction on. The first I went by the manufacturing recommendations. The last two I have done more reducing for the thermal pad. The last one was at a 20% reduction an
