Profiling LQFP-144 with ground plane

Electronics Forum | Mon Feb 28 21:30:34 EST 2022 | emeto

Couple notes here: 1. Try to shoot for 250C peak temperature. 2. Use all your 10 zones in profiling for more accurate profile. You should not reach your highest temp in zone8. Try to reach it in zone 10. 3. Go quicker. Your profile might be too long

SIPLACE D1i SOT(SMT Transistor lead lift up detection)

Electronics Forum | Wed Mar 02 04:47:41 EST 2022 | shrikant_borkar

Dear All Hopefully you got the situation on SIPLACE D1i and SIPLACE D2i. Pickup up Place machines. Is the lead bend upward of SMT transistor detection is possible on this machine? If not is it possible to get it detects by optimising it's windows.

Drying PCB after contamination measurement for rework ?

Electronics Forum | Wed Mar 02 13:15:16 EST 2022 | chris007

I am currently working on a manufacturing flow where some PCBA are processed with reflow oven (after being baked before processing), then cleaned with bath, then passed into contaminometer, passed into AOI. The point is after all of this, if AOI dete

I have successfully revived a dead hard drive by buying an the exact same model and swapping the circuit board from the new an presumably good hard drive to the drive I'm having trouble with. I have done this twice on hard drives that were between 1

We previously labelled PCBs after assembly but before AOI. Now we need to trace panels during assembly as well, so have the need to apply labels before the assembly process starts. Our stencils are thus not stepped to accommodate labels. I suppose t

I wish traceability was not part of our job. If I have to pick, I will laser etch barcodes rather than use labels. Small footprint and fine pitch parts will always hate the label when you print paste. Pick thinner labels, keep away from problematic l

I have a used MYDATA Pick & Place Machine. It is MY9 and year 2000 Model (almost 22 years old). I have 5 extra magazines of this Machine (MY9). I want to know, if I can use these Magazines with any other latest MYDATA model. If someone can tell me, w

How far from apertures is the label supposed to go? I'd say 1 inch is plenty. 3/4 inch might be plenty also. Do you have the ability to measure paste height? I'd say place the label on one board and print two. Is there an appreciable differenc

We are still running an EKRA X5. 2008 build. 1,366,000 cycles. Being swapped out in the near future with an X5 Pro. But we're going to hold it for emergencies. We've found the older X5's are pretty bullet proof. Just keep up on the maintenance.

MY12 Dual Vision Camera Calibration issues

Electronics Forum | Tue Mar 15 17:47:24 EDT 2022 | guyt

Hi, Has anyone had a issue with a MyData my12 dual camera system, were the calibration always shifts up after a few hours of use. It's not the mechanical calibration. it is like the machine loses it's software calibration co-ordinates ?? Any ideas
