Don't get yourself wrapped around the measure solder paste viscosity axel. Observe the paste handling and preparation instructions provided by your solder paste fabricator.

Hi Dave, Thanks . But it's one of our customer requirement to have in house solder paste viscosity measurement. Regards, Ameen

This would be a highly unusual "requirement." In house checks on paste viscosity went the way of the buffalo years ago. The question to your customer should be: why ? All of the mainstream paste suppliers should be able to supply you with a COC th

I cannot see the logic connection between HIP and RSS or RTS, or between HIP and solder paste volume because volume is ok. Did you measured the BGA solder profile?
