I've tried a different lot of the same double header connector (yes its double level right angled header conector) twice but nothing has improved. I've also suspected that top row of the connector has greater heat sinking capacity (which should hold

I am having a common problem, justifying capitol expenses. We are currently using 0402's and BGA's and CGA's with 1MM centers. Our current equipment is horrible, we have a hand operated screen printer machine (No vision system) and we are placing all

Hi, What are you doing for reflow. Sounds like a cheap MYDATA TP machine second hand might do the trick, but don't know if it could do 0201 though. You can get a fairly ok manual stencil printer that might do the trick. We had one that had a linear

Hi, I need help with our MPM UP2000, the stencil and the lamp boards won't turn off completely, they are both on at the same time. Turning it on would only make it brighter, turning it off will just lose the brightness but the lamps are still on. I h

Shean made some good points and offered some good starting resources. Adding to what he said, I would also mention that many times, even a no-clean flux can cause contamination that requires cleaning. Our lab has dealt with numerous cases of client

We are seeing more and more jobs come in with matrix tray parts for our mydata machines. The problem is that the largest Y wagon will only hold 3 or less trays. We have some jobs that have 10+ trays. Currently our operators cut the trays down to sma
