We've had similar "disputes" with our quality department. A technical engineer from Nordson told me that the flourescents in the coating can look faint depending on the angle in which you look at the surface as well as how solder joints reflect the

One of the things you need to know are the parts you are building Flight Critical. Meaning if the board fails will it bring down the aircraft. Or non critical meaning one of the over head light will fail as an example this determines how much latitud

Does anyone have any experience in point to point laser soldering and laser light reflecting off of SMT component 'J' leads down on to the laminate. This appears to be a random situation we cannot understand nor control.

There are several types of lasers to do laser soldering. Panasonic also has a high intensity light that can solder as well. I've tried em' all and two over whelming things stand out when it comes to this type of soldering. #1 is preheat. It seems

Jason, If 225C is the topside temp of your board just prior to hitting the wave, I would say this is too high. Your flux suppliers data sheet should tell you an ideal topside temp for good flux activation, probably around 190C. According to the Bi
