After you tried the procedure, what the MCS error indicate? If you try to format the PC, all data stored will be erased.

Yes, but it does not continue, it tried to weigh the squeegee but then after trying several times it would come up with an error that the Squeegee Left is not Free (up). Cheers

I have not seen hold size as an issue when switching Sn/Pb to Pb Free wave soldering. Trying increasing your dwell time in the wave- typical for Sn/Pb is 2 to 3 seconds. Try 5 seconds to see what you get.

Funny you mention this. I tried this first. I have one now I am trying to sell for $87 dollars on EBAY. I am sure it could be useful for something other than electronics inspection. For electronics inspection of completed circuit boards it BLOWS!

Try running the second side first on a board. If it wets well, it points towards your board house. Run a blank board thru your oven and then try your normal process. If you see issues with the first side now - it definitely points towards your boa

From what I can understand, you say this only happens on one type of BGA (?). Try baking this BGA. You may have out gassing during rework. Do you use tacky flux during rework? If so, try a different flux. And last, check your rework profile.

Too much flux will spatter and can leave balls on either side. From your pix you may too little flux. Try turning up and see. Also try hand applying your alcohol based flux and running through. Will take away a few question marks.

I did not tried this before (never hada chance to do it) but I considered such option - maybe try using temporary wavesolder mask on such small components. Run both sides of PCB through SMT oven and then mask 0402 completely and go with wavesoldering

Has anyone used a hot press to bond new pads to the boards if they have been lifted? we have one and have tried and carried out some DOE's on FR4 boards but when trying the same settings on Polyamide they basically fell of can anyone give any pointe
