Hi ! The main problem being faced currently is formation of solder balls - to be precise, these are micro solder beads generally found attached with bodies of SOTs, Chip Caps, Chip Resistors, between pins of SOICs (50 mil) - lying on PCB surface,

Hi Boys and Girls, I've been given the "task" to turn off the nitrogen in our reflow ovens. I am using the BTU, TRS series ovens, each with eight zones. Also, I have a couple of new BT Paragon ovens with 10 zones. We currently are running Qualite

On "Solder beading seemed to be a problem", consider revisiting the thermal recipe used for reflow. The PTH barrel may not be getting warm enough. On "Component not being designed to pin in paste work, with no proper standoffs", consider: * Using a

Hello everybody. Remember I posted some questions on the smtnet regarding placing the thru hole connector using paste and reflow(pin in hole). I have able to accomplish the process succcesfully.....but I have a problem. The boards are failing at the

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

| Dear guys, | | I have some problem on assembling micro-BGA with solder paste (63/37). The micro-BGA we assmeble is 0.75mm pitch and with 45 pin (solder bump is 96.5/3.5Ag). The stencil is a laser-cut stencil with 5 mil thickness. We are now usin

Can you describe the failure mode of the soldering defect, i.e., is it failing to meet the height requirement for a castellated termination due to not wetting of the component terminations, or not wetting the pads sufficiently, or....? We install a
