Copper Core MCPCB vs. Aluminum Core MCPCB

Electronics Forum | Wed Jan 10 15:11:18 EST 2018 | emeto

Copper has CTE of 17 which I think is closer to FR4 than Aluminum - 23, so in this aspect should be better. However, copper oxidizes very easily and is also 3 times heavier.

Pcb Drill Hole as Fiducial

Electronics Forum | Tue Feb 20 14:39:59 EST 2018 | harlymh

Is it good practice to use a PCB mechanical drill hole as local fiducial? Would it increase my placement accuracy? Or should I stick to my panel fiducials? We're using a panel with 4 boards and we're trying to reach a 50 microns accuracy.

Good luck, get them to throw in P-Tools as well. Not seen it running with 12 heads, but know a fair few people with M2's & M4's and they rate them.

Hi all Does anyone here have any experience in calibration of iPulse machines? (M10, M20, M4, M7). We would like to correct camera and placement offsets. I believe this is done through AMF, but wanted a bit more information. Thanks

Further divide the ground block into more than 4 panes. Also think about using, assuming you have good placement of using Loctite chip bonder on two opposing corners. Lots of ways to get good results

DEK 265 GSX air conditioner refrigerant pressure

Electronics Forum | Sat Mar 30 13:33:50 EDT 2019 | stephendo

This is not an HVAC unit. This is a small unit attached to a production machine to keep the solder paste from drying out prematurely or slumping. The volume of air being cooled and desicated would be less than 3 or 4 cubic meters.
