80??? Whatever leads to you to that assumption? I'd love to see a study stating that. Based on experimental results at our facility, overvolume due to the screener parameters have rarely caused a solder short. so, in conclusion, does one need a solde

I worked for a medical instrument manufacturer a few years ago and we had to calibrate all measurement devices. That included everything from our vapor phase oven's thermocouples to 6 inch steel rulers. I don't see any logical justification if you'

in regards to repairing all these boards, do they consider the end cost of the product whether it's worth it to do so or not? if it does, would you be able to do it in house? and how labor intense is the job? there are machines out there for mass rep

Intermetalic Layer (IL). A compound formed at the interface of two different metals, whose atoms have an extremely high natural attraction for each other, so high, that they do not bond to other elements by any other means. Also, intermetalic compo

Good Morning Everyone, It has recently come to my attention that components (PLCC's)are being placed in the sockets prior to wave soldering. Some of these components are MSD's. They have been overexposed to the atmospere, then are subjected to the w

We socket no parts prior to the wave. This practice is an artifact of the days when we�d solder PTH socketed parts from the heat of the wave being conducted through the socket leads to the leads of the component. Sockets??? Thaint sockets no more.
