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?

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

If the soldering process is not controlled, the results are variable, regardless of the flux type. Tell us more about your concerns, process, solder, etc

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

Hello I am looking for any data that confirms the long term reliabilty of no clean paste as opposed to water soluable. Does anyone have any past experiences of problems when changing over from water soluable to no clean in the SMT prcocess?? Thanks i

Two things: 1 Go to IPC and buy "TP-1115 - Selection & Implementation Strategy for A Low-Residue No-Clean Process - Provides direction to electronics manufacturers interested in adopting low residue (LR) assembly technology. It addresses the concern

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

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

Hi All, Via X-rays, we found solder voids appear on PTH location, especially on Dimm connectors area. We think this should be related to PCB issue as we found solder unable to fill up the PTH hole during bare board testing at wave soldering machi
