Choices are: * Run a Cp, Cpk capable profiler through the oven. * Review the results of your supplier's process qualification that would include Cp, Cpk on their oven. Handspring contract [REV. 6 - 7/1/99] with Flextronics says: [snip] 4. Process Ca

Enhanced board set-up, set conveyor width, load board, (your fiducials must be accurate!), use two fiducials to set reference point, click on placement(s), move crosshair to centerpoint, use two point teach to teach one point in the center or use cor

We conducted a DOE to establish our print setup parameters. These will of course depend on the paste you select, and the thing just runs. The techs store the head in a ziplock bag when not in use. When they need to run, they just attach the head,

This was a rather intersting little project to work on due to the fact that I had such a variety of components placed in SMT ( your regular 0402 passives, ,BGA's Qfp's ,TH and SMT connectors ,plus the pesky micro BGA) I ended up with a 5/3 mil electr

Hi All, We have a handfull of GSM's here and some are newer than others. I was wondering what the options are as far as upgrades to the VME chasis. We have our oldest running with EPC-4, EPC-5, EPC5A and so on.... Can newer EPC units be used in t

Probably not on the whole job, but maybe the 1-5 boards that were used for setup control. Especially MELF's are not super process tolerant. I'd probably allow standard caps and resistors one more time, but I'd need some test data to back it up. I'd

Hello, We are planning to buy a desktop AOI system and were able to experiment with a Mirtec MV-2 system. Results were pretty good, except for some types of solder inspection. I am wondering if anyone has some experience with the Mirtec MV-3 (3D 5-

Mydata would be good, Contact Systems would be good for what you are doing, very good software, crappy feeders but fine for 0805 parts. You may be able to get a Universal GSM pretty cheap these days. If you make a decision then look for a machine you

21 hours to go, then I find out whether I own the boat anchor or not! Ahh, going down from 1300 to 960 mm is a great reduction! (Of course, that's a different machine, so it may not apply.) Maybe I'll try to get some more detailed pictures to figu
