We have a problem with QFN IC's with NiPdAu plated pads. Our ULC's don't see the pads due to the almost ideal reflection. Vision sees the pads almost black. As we don't have OAL-cameras (which can help in this case, I assume), I am thinking of back-l

Hi all, We use the IMF converter (and a floppy disk) to move programs to and from the MCS30. The only way to get to the command line in the MCS30 is to reboot and do the ctrl+shift+_ ketpresses. I wanted to try to add an entry to the Fuji User inter

Back in a former life, we had 3 products that were PCBs bonded to aluminum boards. We used a PSA from 3M to bond the board to the aluminum. Polymers are almost invisible in x-ray, but ultrasound worked quite well. You should try CSAM. Don't know

If you have trouble also you can check out Valors vPlan, i have it running Yamaha YV100Xxg machines - they support Assembleon versions too. Can generate VIOS files from ALtium Input - either CAD DB files or ODB++ as Altium Designer supports this now.

Hello everyone. I'm looking for some general information on reel counters. We are trying to tighten our inventory counts, and rather than estimate a reel we're looking into getting an accurate count via a reel counter. So first, I'm wondering what

Dang, you're picky. Try buying your operators mittens, and then tell them that your company has discovered that mittens generate less ESD so they're making them mandatory now. Then...after a few hours, bring them their gloves back and tell them that

You should do some testing what temp you really get. Solder will melt 260~300ºC. Back to the initial question, CEM-3 is a bit harder to buy and has not many varieties. Go for FR4, you can go for a higher Tg then the common 130ºC. There is also 140,

Last July I posted a query about reflowing leaded paste to gold plated boards, I wasn't getting a good reflow. The answer that seemed to work was dwelling the board at reflow for the maximum recommended amount of time. Would anyone have an opinion on

Thanks to all for their inputs. @Hexielectronics, I am now trying to assemble the board by attaching it to a frame and removing the frame while waving it. I plan to put the boards back on the frame after the board cools down. Could you explain more
