Which among the two profiling method is more reliable/accurate in getting the oven thermal profile? a) using a HIGH-TEMP solder wire then soldering the thermocouples onto the profile points of the board (e.g. component lead etc.) b) not soldering t

Is anyone aware of some guidelines regarding through-hole in SMT pads? One of our designers wants to add through-hole leads in some SMT pads for an inductor. The size of the hole is 0.032 inches and takes-up approximately 25% of the pad area. This

I've been asked to put together a "Technology Road Map" that shows the direction components (technology) and the equipment that places them might be taking for the next 10 years. For instance, micro BGA might require more sophisticated pick-and-plac

I am interested in seeing how some of you quote smt work. Currently we quote off a bom without component packages known then look in data books to find out what type of component they are. This job will be mine soon but i really believe there is a be

Does someone has experience with solder stop on components to avoid an Viking effect (no solder on the pad, all solder on the lead)? What kind of solder stop does work well? What is dangerous? What has to be kept in mind when using such components? B
