Hi, Does anyone know what kind of cable the thinline profiler uses? I recently acquired one of these profilers, but it came with no cables. I went out and bought a female to female serial cable, but it did not work. It will not communicate with my P

If you know a little about electronics, you can probably figure it out. Or just buy one from Mole. Do you have software? More than likely you will have receive, ground, and transmit. Open up the Mole if you can and look for the RS232 chips(Max232

It is CSP reliability issue, which is the mobile CPU from Spreadtrum. All the tests passed and shipped to customer. They assembly them and tested but failed. After they reflow this CSP with hot air gun, some of the boards passed. We got some board

THANKS FOR YOUR REPLY GUYS... more background... solder paste is Water Soluble. We mask the potentiometers prior to aqeous washing using solder mask, then our operator brush the solder joints with IPA after the Wash Process...I'm concerned about th

This runs up a big caution flag in my mind! Counterfiet parts are often produced by removing the original markings and remarking the ICs with different part and lot numbers. I am not accusing you of this BUT we have recently been bit by counterfei

Yep, many of us have seen this firsthand. I had a customer who fouled up a job, then "found" a deal on some (10) very expensive Xylinx parts, and badly needed these parts to complete the job. Everything looked good afterwards, but nothing worked. X

There must be discussions about this on SMTnet but I have yet to find them. I would like to hear from all you smart people about running LF and PB BGA�s on the same board using 63/37 solder. If you run your profile up to peak at around 225C +/- (nitr

We are having issues with these parts tilting to one side during reflow. Of course when they are tilted, they have to be reworked because the shield won't fit on. Changing board design and part design is not an option.... I think there are 2 reasons

Voiding was also the issue I had. I could reduce them substantially by pre-baking the boards, but that's obviously not desirable. Hopefully the chemists have come up with a solution. I extruded some pretty cool looking solder shorts through the vo

As Mark stated in a different reply, we also send our Pb-free BGA's out to be re-balled with SnPb paste so that we don't have to elevate the reflow temperatures. You have to be careful regarding the individual components on your boards as although m
