Are there better options? Dude, EVERYTHING else is a better option. Gluing aluminum foil down to the bare copper would be a better option. ENIG (Electroless Nickel Immersion Gold), Immersion Silver, Immersion Tin, and OSP all provide flatter surfac

I have to build test fixtures for RF Power transistors. These components generate alot of heat so the PCB is soldered to a baseplate. The problem I am having is that I am getting too much solder flowing thru the via's and flooding the topside of th

I have tried covering the vias with thermal tape and that did not work. I like the idea of plugging the via with a temporary solder mask. I will try that the next time I build a fixture which should be tomorrow. This is mainly a problem only becau

Plugging the holes with temporary solder mask helped some, but once the solder starts to reflow, the fumes from the flux pushed the solder mask out. What I ended up doing in addition to using the temporary solder mask was covering the areas of pcb w

Fortunately, I only have one more set of boards left. I may or may not have to assembly, I have not gotten the word yet. Anyway, it would be good to know how to rework the boards with SR1000. I usually do not have any input when design team spins a

Greetings all, I'm pretty new to the SMT world, having been a class 10 fab monkey in my previous life. What I'm looking for is recommendations for pneumatic lead cutters. I need them to flush-cut as close as possible to the via without destroying

We have seen a similar problem. Turned out to be mechanical stress on the component caused by the method of location and clamping at ICT. Where is the component located on the assembly? Poorly adjusted clamping pillars on clamshell fixtures can cause

Right now, I am mostly getting .pho (gerber files) and .asc (pads) but i don't have anything to convert it to excel or text files so that Cad2cad can read it. I have camtastic! 2000, but i haven't figured out a way to convert it. I want to able to e

What is the spec or true classification for the leads for an Electrolytic capacitor? Is it a : 1)Flattened coined lead??? or 2)Flat Lug Lead??? There is some confusion as to how we should be inspecting & accepting the toe overhang on these per IP
