We are a small contract manufacture who started out using the component manufactures part numbers. That lasted about one month then we had an apple and orange with the same part number. I looked at what my customers were using, one had a real good

BGA Placement is not easy as we think, Mainly you have to make sure you don't have acceessive amount of paste, try to paste your board as it covers full ball, make sure it is not short before you place any part. If you placing the BGA by hand be car

We are using Mulicore MF101 flux and a Vitronics selective soldering machine on a lead-fee assembly and are having trouble with nozzles blocking even when the nozzle aperture is increased. Has anyone come across this problem before using fluxes with

We use SN100C for wave soldering and hand Lead free soldering and have had very good results. The wire cored solder for hand soldering flows good and makes very good solder joints. The SN100C in the wave solder machine also works very good. We use

Lots of small parts, lots of hand soldering, lots of tired eyes inspecting on lots of boards: yields lots of room for error. How about this: * Part removal ** Cut each resistor between the pads using dykes ** Using a soldering iron [or hot air pen],

We have been using a selective solder system for all of our automated LF through hole processing to this point. It has served us well but volumes are increasing and we are getting ready to pull the trigger on a full size wave machine to handle the l
