We have had this issue on our Delta 3 waves and determined that there are small pin holes in the solder pot. We had plates welded to the outside of our solder pot on the lead free wave and this bought us enough time until we could replace the wave, a

Thanks Dave, Now I am going to find out if I am consistent with the IPC.

| Recently, there has been an upsurge in the Pin Hole/Blow Hole problem in our wave soldering process. We are baking the PCBs for 2 Hrs. at 125 degree C. The Wave Soldering profile seems to be O.K. Still the problem is persistent. Can somebody hel

We are continuing to struggle with voids under BGA's. Our problem are not consistent. some CCA's are perfect but others have pin hole sized voids. Does anyone have any feedback on Indium 92j and how it performs for bga's?

Are you using masking? Conformal coat will de-wet (no pin holes usually, though) due to masking tape adjacent to affected areas if the tape glue chemistry isn't compatible with the conformal coat.

You can try using a PTH or a tooling pin hole. It's much more consistent than fiducials.

When you talk about baking, I get the impression that you're talking about boards. Are you components dry also?

Hi Davef, Yes we have tried few component for cold baking for around 7 days around 50 to 60 deg C.

Can you share the oven profile? For me it looks like the profile has fast ramp up and short TAL period. How many zones the oven have?

Hi, We are using 10+2 reflow oven ( BTU Pyramax 150 ). We have tried with short TAL ( RTS profile too ). As of Now we are using the attached profile, which has given us lot better results. But the issue is not eliminated. Thanks
