Hi Locktite is telling you to cure first, maybe for a good reason. So the epoxy becomes stable just before solder reflow moves stuff around and around and then settles. A WEG yet if you did some cross sections and analysis you might find piles of

Hi I think you answered your own question. How much depth have you already established If 0 than commissions are high and base salary high Without a base salary forget it for a good professional If a cake walk due to past practices than commi

I work for a large Contract manufacturer. We use Fuji Siemens and Universal. Universal is by far the most stable reliable system. They always have the parts in stock we need. Great support. Samsung has now pulled out of direct sales in the US. I woul

We can solder and clean lead-free in well-controlled and stable processes. We have no reason to believe that products made with lead-free will be reliabile. We know that lead-free soldering is worse for the environment than other less costly proces

Hi I see David F already gave a good answer. The basic advantage, if you can afford it, is a more stable PCB during the soldering process. Higher Tg enables this. Also some materials serve to match CTEs (coefficient of thermal expansion) a bit bett

Hello Dave, First you must make sure your measurement system is calibrated for accuracy, repeatability and reproducibility. We perform a standard GR&R Study on our CmController system on a regular basis to ensure that the system itself is capable to

Stability of process is what your measuring so lets not assume a stable process(if your process was perfect you would have no defects). With no test a medium complexity board will be around 68.7% (according to Consulogic). I dont have many other sour
