KS: You're correct. The standoff on a 1.00mm and 1.25mm BGA is high enough to allow cleaning. The standoff on 0.8mm BGA does not allow proper cleaning, even with saponifiers.

Solder volumes is very important parameter to keep under control in order to get a good and reliable CCGA solder joint, and an automatic 3D paste volume inspection is strongly recommended practice to use. Questions: - what Column pitch do your CCGA h

Wow, you're very correct. I guess we use silicone to calibrate our machine, as follows: XPS spectral measurements of dimethyl silicone should include O(2s) at 25 eV, Si(2p) at 102 eV, Si(2s) at 153 eV, C(1s) at 285 eV, and O(1s) at 533 eV. The C(1s

Help for replacing BGA with metal heat sink

Forced gas (hot air or N2 according to solder paste or flux) will be the solution. To rework Ceramic (Aluminum lid Heat Sink)BGA (32 mm square ) or Ceramic Colum Grid Array C-CGA 1,25 and 1,00 mm colum (pitch 42,5mm square), also them capped with a
