Without further information my first guess would be lack of flux to "cut through" the ENTEK layer. Question: In X-ray is the suspect ball of equal diameter when compared to adjacent balls? If no then the volume of solder is different which would po

Hi, I am considering to use pressfit D-Sub and DIN connectors on a backplane. The IPC guideline does just cover pin protrusion for soldered pins, which have to be flush with the board as a minimum acceptable design. Yet, if the backplane may be thic

I think that as long as the compliant portion of the pin is completely in the board, pin protrusion should not make any difference. I have seen some large Aerospace companies internal specifications and the two requirements seem to be that the compli

Yes, you need work with supplier to see if can run pin in paste for these connectors, even do some experiments. A step-up stencil would be good for these connectors, also connectors pin size and length match with PCB hole design.

Yes, unfortunately a lot of datasheets these days do not contain the temperature resistance to determine if it can handle the PIP application. In the past I have always used a 250 C at a min of 5 sec for the material. Also, the part should have sta

In solder bumping in flipchip technology by splder printing, the precise control of solder volume and height is very difficult. Therefore I'd like to know the solution of this problem. Thanks
