Hmmm.... I had Intel survey my process on a mixed alloy line for 2 days. They periodically removed boards from all stations on the line (including post reflow). Boards were "crushed" and spearated into constituent plastic, ceramic and metals. All

The machine is 2000 miles away, and the eBay auction has not closed yet. I'm working from what pictures and spec sheets I can find on the net right now. If I do win the bidding, I will need to be sure there is an opening wide enough for the machine

Thanks for the answers. Hi Dave, I'd love to use some of the durastone we have here, or some Durapol or Delmat (never used Glastic before though), however we need a compliant material for the blade to go into slightly, otherwise they tend to snap or

First, don't put solder paste in a wave solder pot, the 50% by volume of organics and volatiles will gas off in an astonishing amount of fume, leaving a dismaying mess of spent resin and molten plastic in your pot. Second, when you say, "Paste that

If you are in the middle of a run and can't get a replacement stencil there immediately, you can always put a little kapton tape on the bottom of the stencil to mask off a portion of the DPAK pad and reduce the paste deposit. We have had to do this

Looking at the Emerald machines, they do seem like they'd fit the bill quite nicely. Other than the operating system, is one generation markedly better than the others? I have all the data on the X2 from the manufacturer's site, but what changed from

I am guessing Theresa is saying when that some SMT parts are soldered (not glued) very close to some PTH parts. So close that they can't effectively mask the SMT parts and have an opening for the PTH part. At the company where I work, we've been tr

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

We assume the three leads are lined-up perpendicular to the wave. Without taking corrective action, we know this: * 50 thou pitch will bridge * DIP do not bridge As a corrective action that doesn't invovle a respin of the board, decrease the solderm

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
