Solderability!!! The CM in question has probably seen too many solder problems with White Tin in the past. We have had the same issues. To save us from spending too much time and money(verifying pure Tin plating thickness, Chemical leaching from th

There are no batteries in mydata magazines. This problem means your voltage is outside it's allowed range. In this case I think it's the 15 volts. If you open up the bottom of the machine and pull out the carriage you'll see a rectangular box that ho

The variables to study: * Dwell Time * Contact Length * Conveyor Speed * Parallelism * Top-side Substrate Temperature Before wave * Solder Pot temperature All of these variables are inter-related (ie changing one variable will affect another)

It sounds like more has to do with plating. you may also check out the voiding issue especially if you have new FAB or the supplier. I had problems with a RF chip in QFN package due to insufficient grounding that voiding caused. This ground is often

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

And that's better because? I think the guy that thought this up has never been to a board shop or knows what is involved with plating. Why does he think it's the board shops that will disappear? Maybe they will simply build the board over the compon

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

Good morning Steve, What does optimizer say? What is the error generated by optimizer? Could you tell me exact error optimizer gives? Topaz ties to fit all feeders mechanically into the feeder plate when optimization starts. Optimizer generates an

If you're getting that kind of error it's most likely that your feeder bank hasn't been told that the stick feeders can be placed on the back of the machine, or like they said in earlier posts, the stick feeder size itself may be incorrect in the sof

Hi Bud We buy what you're selling, when you say, "I suspect ... coo planarity of the connector during soldering (bending like banana) and that is why first or last leg is not soldered." This component is probably acting like some BGA that curl at t
