1) At this time we do not have a design engineer. I have contacted the PCB manufacturer about changing the drill file to close up the diameter on the holes a bit. This should allow the wings on the leads of the component to rest on top of the holes i

Hello all, I am having difficulty with an OmniExcel 10 oven. Zone 5 upper will not hold setpoint = 165C (it typically runs ~10C higher). Here is what I know: 1. The machine is not turning on zone 5 heat when temp is too high. 2. Zone 5 lower is

Thanks Dave , my question is about Spopov want to try "Lead Free" SnBi (but uses it on Leaded finishes), but is worry about its low melting point (at this point, no longer 138 degrees as he wrote, but rather in an unknown and unpredictable range bet

My first attempt was similiar to that. It was a straight ground trace running past the circular pads that were recieving the shocks. It was hit and miss when the arcs would occur. When I cut notches in the trace so the ground line had a point next to

In order to be able to do full prototype assembly, you will need to be able to mount and reflow a large number of different devices of differing technology. One part might be a simple QFP, another might be a .4mm pitch uBGA. If you are prototyping a

I'd love for safety to be number one around here. I cringe a lot as I walk through our facility, I'm shocked by the things people do without the proper safety equipment. I always go and grab the equipment and bring it to the employee and explain, for

I have worked construction in both domestic and highrise in the last few years. Not wearing safety gear is an immediately sackable offense. It is not a bad way for it to be. Hard hats are always required on multi-story, steel capped boots are always

Juggalo, Your boss obviously hasn't thought about the implications of taking a complacent attitude toward safety can cost. He is liable if someone gets hurt working in his plant who isn't wearing the proper safety equipment or none at all. It does

We are using our selective solder machine to solder a backplane with sixteen (16) 4x48 pin 0.080" connectors. Our first pass yield is about 85% meaning that 85% of the connectors come out with no bridges. Not quite as fine pitch as your connector a
