| I am looking for a rule of thumb regarding the maximum ramp standard components (chip capacitors) can tolerate without failure during the reflow process. The standard seems to be 3C\second, but this figure is generally derived from the average ram

| | Is anyone aware of some guidelines regarding through-hole in SMT pads? One of our designers wants to add through-hole leads in some SMT pads for an inductor. The size of the hole is 0.032 inches and takes-up approximately 25% of the pad area.

Hi Dave! Dat' be da same board we ran at NEPCON East in 97'! Ray Rua was running the TAC line then (his company usually runs the TAC line at almost all NEPCON shows). A couple of things I wanted to point out on that GIF image that might b

I hope you'll take an answer from the sunny UK. I don't usually read these forums but contribute to similar over here, hence the late response. We have an Invicta Sabre 757 machine in our Demo room, running with Zestron SD 300. We give the PumpPrint

OK, disclaimer; I'm a salesguy, but I was a process engineer for quite a lot longer than I've been in sales. Your question is very vague, and may be difficult to answer. There are many ways to configure AOI to inspect solder, but as has been pointed
