Every paper I've seen published shows that BGA voids either have no effect or actually give a slight improvement. The one exception are voids with a root cause in bad incoming boards, such as champagne voiding where nearly the entire interface is go

Do you of reducing hole size of DIMM connector will improve solder voids??

What are you trying to do: * Improve hole fill? * Reduce PTH voiding? Hole fill: Search the fine SMTnet Archives for stuff like: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=36063 PTH voiding: Ideally, there are no voids. We're unawar

Are the voids in the balls of a BGA? Are you verifying this through x-ray if they are? some voids depending on size and location are some what accepted. Solder paste type? Solder paste date code? Humidity high? PCB's been stored in a truck trailer?

hi,Toni, we use only FR4.Some of PCB we order in China and Taiwan.With these PCBs we can't any problem.Other PCB we order here in Bulgaria.The problems with voids start last year - we have voids only in PCBs from Bulgarian factory.The process is sam

I am having problems with voids in our soldering process. I believe it to be the fact that we use a no clean flux without control on how the boards are handled (gloves, procedures, etc.) Does anyone have suggestions on the appropriate place to start?

Not enough info, when you say no clean flux, is it for wave soldering process, please provide more detail, SMT or wave, is it all the joint which you find the void? Rgds

We have prob Solder voids for Connector, Micro D. We used HMP solder wire and pcb thickness is 0.093".

We'd go with the formula above.

Are your voids looking like blow holes also? Is this only occurring on the solder joints of the Thru Hole components and Via's? Or does this happen on SMD pads? My experience is that we have seen this but only with some of our older PCB's which are
