Solder shorts with DEK printers... | 4 September, 2001

We have problems of solder shorts while using DEK Infinity printers.

Some of the manufacturing lines are configured ina way that the side (bottomside) of PCBs mostly with passive parts is screened first and then the otherside (topside) of the PCBs with BGAs and MBGAs is screened.

I believe the problem is due to the reversed order of process. Is it true that if we first screen the PCBs with topside will eliminate the problem?

Thanks and regards.

Shvetang.
