In the past I have worked on 600 Amp FET Blocks. The rule was no voids. The circuit board would be heavy copper. 4 times normal plating time. Not particularly high resolution on the board say 20 mils. To help with the heavy plating. The boards were t

I have a double sided PCBA setup. I have MSL components on both assembly sides. When I run Assy Side one I am within the allotted hours remaining on the MSL component. I then wait 40 hours before running 2nd Assy side. By then the hours on the 1s

Hey all, We are a small electronics manufacturing company who has been using the solder reflow process for years, but we have been hand placing components. We only run the system 2-3 days per week. I have been looking at buying a used pick and pla

Sergey, I understand your thought process kinda, but you are not going to justify yourself a pick and place line based on a "simple" 5K board contract unless you know something we don't. You do not want a machine that has buggy or slow software. Any

UL listing is handled by the customer typically. I am assuming you are a contract manufacturer producing only a component pcb assembly for use in a product final assembly and not the final product itself. We are a manufacturer that does our own popul

Here is some food for thought. Try to answer these questions yourself and I am sure you will see huge improvement. Reasons: - Bad PCB design - Plating-uneven HASL cause more than OSP Au/Ni or Silver - Poor paste and print quality - uneven paste ca

Mid-production our KE-730 halted and gave us a “SUB CPU1:BUS ERROR” message on the video monitor. Then we got on the same monitor a detailed error message with address and byte information (unfortunately I didn’t copy the details). Now when we boot
