I agree with jdengler on the rotary table being skewed. You need a couple of dowel pins (1 1/2" long x 1/4" dia., I think) to align that disk. Each idler is held on an eccentric cam and can be adjusted to square up the rotary table by dropping the do

Our board layout folks are currently designing a PWB using a 132 QFN. The component is .5mm pitch with .35mm square pads. The component manufacturer recommends the following footprint: .4mm square land .3mm square solder resist 1.why do they spec

Well, Ray Rassmussen believes that "IT" may put China on it's ear. Not sure about any of you, but I never felt the need to splash water on my face whilst reading this white paper. Hate to see how he'd react to seeing a board going over a 500 degree

This is the last comment I will make on this subject. To me this occam process makes a whole lot more sense than lead-free. My whole life I made a living in soldering so I would hate to see it go, but we can�t ignore innovative new technology. Lead-

Our preference has been ENIG. We find that we achieve higher quality (visually) soldering for through hole and surface mount parts, with less handling issues than when we use white-tin, or immersion tin. We are about to do a test on some boards tha

I have been asked by the powers that be to create a pick and place program for a board that will be split between two Quad 4c machines. Half of the components will be put on with one machine and half with another. I know that the Autoprogram software

Should be do-able. Check out a couple of things: 1. Temperature tolerance of the LED's. If they can't withstand reflow, then you won't be able to do it. 2. Height of the LED's versus the travel of your pick/place. If your pick/place head won't t

Hi All, Via X-rays, we found solder voids appear on PTH location, especially on Dimm connectors area. We think this should be related to PCB issue as we found solder unable to fill up the PTH hole during bare board testing at wave soldering machi
