QFN's and LGA's

We just placed a 56 pin QFN, 1 per board, on 10 boards and had zero defects. A good paste job, proper placement and a correct oven profile are the keys. If these are set up correctly, on larger runs your defects won't be zero but they should be le

Our MPM Up2000 HIE is having a communication problem with any upstream machine we place in front of it...i.e. conveyor, board loader, etc. It all started when we removed a conveyor from inbetween it and a board loader, and hooked those machines up di

board input sensor sensitivity? maybe conveyor movement triggers it and because of that it sends pulse. conveyor moves few millimeters, how does machine act?

that sounds like bad relay or relay control. are you in position to check it on relay pins? I would go from there.

We use both labels and lasers to mark our boards. Since implementing the lasers, the downtime attributed to bar code labels on those lines have dropped to virtually nothing. We still have problems with the labels wrinkling during reflow making read

High-end SPI and AOI?

Electronics Forum | Tue Oct 13 08:09:53 EDT 2009 | kudamarani08

Can anyone help me recommend or simulate a SPI and AOI machine that can balance our FUJI NXT 1 with 14 modules. We are using MPM accela printer. 200 UPH is our target. Here's the PCB dimension length(x) = 399.92mm width(y) = 141.626mm Thanks all!

here is well explained SMEMA interface http://www.daghee.com/?p=326 so, disconnect printer from upline modules and check are any 2 of 4 pins shortened(should be pins No 1 & 2) while machine is ready state. when machine is in busy state the same pin

Hi Ariss_T, Thanks! I actually did check that...that was one of my first thoughts as well. While in the I/O, I slide a raw board back and forth under the camera/sensor and it acted appropriately. I will definitely update this thread as new informa
