Interference to lights from Heller 1707 XL oven

Electronics Forum | Tue Sep 15 01:16:32 EDT 2020 | kylehunter

We have the same issue. It was present with our old 1500 and is even more present with our newer 1800EXL. For us, it seems to be related to the blowers, not the heaters. If we are in cooldown or wakeup the issue is still there with the heaters off.

Just curious if anyone has ever used an EMF meter? I have used a static field meter but that is quite different. I have had hearing aids that had a switch that switched from an audio mike to a telecoil that would pick up the EMF from the phone speake

Plenty of 0805 inductors around, up to 470mH, but nothing that is 26mH. Coilcraft do 23.5mH or 29mH - see https://www.coilcraft.com/getmedia/18dd250a-2b92-4f9a-bcee-3624995acc0f/0302cs.pdf Eaton do a 27mH 0805 - see https://www.eaton.com/content/dam

Hi Smitty, I am currently using Manual Lock Red-E-Set, and never had problems with damaged components. Although at my last workplace, we used VarioGrid, and encountered same problems as you. I suggest checking the pins on the support tools(s) you h

New to solder paste jetprinting

Electronics Forum | Wed Oct 07 15:46:36 EDT 2020 | tamasmagyar

Hi Hearse, I currently use a MY600, with a AG Ejector which can place dots between 0.33 and 0.52 mm. The differences for a MY600 with placing small dots is down to ejector and paste. To be able to place dots as small as 0.25 mm, you would need an

SMT Line Performance Measurement

The best way to measure is by money made(quality product and minimal rework). I worked for a company that asked me to achieve building 100 boards/week for an assembly. A year later they were unhappy that we don't hit 150 boards/day of the same board
