In assembly the bare board is populated with electronic components, called a "printed circuit board assembly" (PCBA). In through-hole technology, the component leads are inserted in holes surrounded by conductive pads; In surface-mount technology (SMT), the component is placed on the PCB so that the pins line up with the conductive pads or lands on the surfaces of the PCB.
Is anyone out there using vapor phase soldering techniques? 1. I'm wondering what results you are getting? 2. How are you controlling the thermal profiles (specifically ramp rates and TAL)? 3. What fl...(view more)
JulianWe are curently using a SMTech AVP 300, which is an in-line semi-automatic printer. Within the next 6-12 months we will be looking to upgrade to a fully automatic printer. I have already had a l...(view more)
CarlOur CP643E machine fails to recognise narrow view on its parts camera and confirmed that the VME48108 Picture processing board is the reason. The part number is AEEPN1603. Can anybody have the idea ho...(view more)
pmaggiI have a block programmed and i want the machine to just do one block at a time instead of doing the whole panel (each panel has 56 PCBs) at once and skipping around. how would i do that? thanks in ad...(view more)

ali.serbetciDoes anyone have design knowledge of why some manufacturers remove solder resist from the area around pads on fine pitch devices? What purpose does it serve? I only know that it would be better ...(view more)
Lebrun BernardCan somebody help me to understand what standards are in place for deinozed water for cleaning circuit boards. I know they are supposed to be in acordance with J-STD-001D, but what does that entail? A...(view more)
Yaser FathHi there, where can I find some hints about placing the temperature sensors on the pcb when determining the reflow profile? I'm interested especially in the case of a pcb having BGA's. Thanks for your...(view more)
