In approximately one month I am installing 2D at our DEK print station. We are going with the basic (cheap) software options and 2D camera. After it is up and running we will determine if it is indeed useful. At that point we will decide on the adva

Another test to consider is dye penetrant analysis. The technique involves flooding the area beneath the soldered part with dye (preferably a bright color, like red). After drying the board+dye in an oven, you peel or torque the part off and inspec

| | | Has anyone out there tried to parylene coat plastic parts prior to soldering them to a pcb? I'm looking at several potential applications where fewer than 5% of my components on a pcb are plastic, yet from a reliability aspect (environmental co

I have a product with mixed in Pb free and Pb BGAs. I decide to use SnPb paste with Pb free reflow profile to make it work for both types of BGA. Do I have a reliability solder joint issue by using this method? How is your opinion on this case? Can

Instead of using adhesives to glue the back side SMD components and wave soldering them together with the through hole components, our manufacturing engineers choose to process the back side components through reflow oven without adhesives and proces

Thanks on the advice isd.jwendell! Yes, the piezo ceramic has a Curie Temp of about 800C, so its safe operating temp should be around 300-400C. How about if my PCB is a prototype, would it be more economical to use hand soldering or just manually app

Hi, if you want to verify the gold contamination, is mandatory to use the XPS and FTIR analysis, but is difficult think about a gold contamination from 3 different manufacturers. Do you have cleaned the PCBs after an erroneous screen process ? If no

Hi Mike consider buying your LEDs from a value added distributor or sending the to a service house for trimming. It's no trick to cut so that one lead is longer than the other although you may have to pay a tooling charge. These people are equipped

X-ray can be helpful in trouble-shooting BGA component failures. Test techs can quickly determine whether or not a BGA has solder bridges. When a bridge is found, this can eliminate hours of trouble-shooting. And when a bridge is not found, the te
