Annular rings are too big, it is acceptable to have shorts on the common conductors. I would be willing to say the "other" supplier may have modified the artwork as well. Good fluxing, preheat and proper immersion depth are key to eliminating short

Ed,,You need a temp gauge to verify tip temp and if it's a digital control iron and it's off usually just junk it. If dial control you can loosen knob and adjust to reading.If you need to know type of gauge and manufacturer drop me a line

It depends on the type of iron. Some of ours have a little plug you pull out that exposes a pot that you tweak to make the temperature of the tip the same as the reading. Others can't be adjusted and the heating element must be replaced if they don't

Hi Eyal, Sure you can do that. You might be able to use your "typical" reflow profile for eutectic, or tweak it slightly. it's a good idea to do a trial run and then get a couple of components cross-sectioned and checked for the microstructure of th

Sorry for the confusion... "WML" is a who... Wave Master Larry... He is a person on the forum who has a degree from Soltec? I don't remember... I was hoping he would have left a comment or some info that we could all learn by. (I am not sure how thi

Why yes, I regognize all the best. WML, I have an idea... I am going to call it, the Dunker. Instead of anyone foaming, I will get the wave operators to throw the boards into a rubbermaid tub full of flux/gasoline mixture and send through to the wav

I agree with Pat. We specify matte finish on all our boards. Once in a while our QC Dept lets in some glossy finishes in and then do their victory dance at the wave chanting "Wut ya gunna do about!?! Wut ya gunna do? Process outta control! Giggi

With the gun you can do removal. Than clean the pads, put some flux, place new BGA(or reballed one) and put it in the reflow oven(if you have one). That's the cheap way you can go without buying an equipment. The other way is to buy machine for BGA

Hi, yes, you can, but it will be subject to long learn curve where i live there are hundreds of GSM repair shops which do BGA rework and replacement with $50 hot air guns only, but i guess they had lot of BGAs damaged before they have learned how to
