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.
Does anyone have a template or a method of approximating remaining part count on a started reel? We are not ready to purchase an electronic parts counter at this point(view more)
Artur Assun??oWe had alot of problem with melf diode short together after reflow soldering. The clearance is about 0.8mm & we used "v" shaped opening . PLease comment !(view more)
Albert Palau LlortNormally the specs I monitored in our temperature profiles are Slope 1-2 Deg C/sec, preheat 60 - 120 Sec at 120 Deg C - 150 Deg C, peak 215+/- 10 Deg C, above 183 Deg C is 45 - 75 Sec, total reflow is...(view more)
Robert FranssonDoes any body know if there are any legitimate health or safety reason's to vent solder fumes, at both reflow and hand soldering work stations? Personally I don't like to have the fumes in my face, bu...(view more)
Bernard REMONDHi, I'm looking for research/study done on solder shelf life by using accelerated aging process ( steam age or dry air oven bake at 150C & etc ) Perhaps you could help to advise correl...(view more)
ClarkI need teoretical info for theme "Matted surface vs solder ball". Is it right that some solder pastes decrease solder balling but give matted surface after reflow? That diference between these pastes ...(view more)
charleneHas anyone looked at setup reduction for machine feeders. We have made some gains through changing the flow of work but as lot sizes decrease the number of parts required remains the same. We remove a...(view more)
anjenkuhnThis is our first experience with running embedded flexs. Our board supplier suggested that we prebake our assemblies before placing components. What does everyone else do? Is prebaking normal when a ...(view more)
werfried kunethHi, our factory is introducing the FPC process. I have some question to ask.Could anyone reply/ 1.how can we fix the FPC in the mounting and printing process? 2.how can we set up the...(view more)
francesco81rsFor anyone who is currently running these machines I would like to get some feedback (positive and negative) on them. How do they run in a production enviorment? Is the modular machine (AX-5) a pain i...(view more)
