Morning all, Has anybody done any pin in paste job with a dispenser? I read somewhere that the needle i.d. should be slightly larger than the hole diameter, but with holes of 1.4 mm I would have to work with a very large needle indeed. How does past

Yeah, adopting is the right word. In this new lead-free era spec.'s are made to stay within the scoop of the RoHS directive. The driving force for spec.'s should be reliability. Did you see any impurity level spec.'s yet in wave soldering for Cu, Au,

Help! Does anyone know how to get a Camolot Gem II machine to put down dots for 0402 placement? I have been working with Electrovert Tech's that say their machine WILL place dots for 0402's. I have reduce the speed of the pumps to half the speed,
