Was this problem solved? What did your boss do to come up with a solution? Have you contacted the PCB supplier? Ask them to have a review on this and give a proper solution. Consider changing your PCB supplier. You got the bad set of PCBs that may be

Yes, and while it did, its been around longer than we have had any sort of process engineers. While the package naming scheme, or lack there of, is a mess. I am mostly curious if there is any other identifiers or naming conventions besides specific m

During production the temperatures on the last 3 zones are approx. 20F higher than the setpoint. The other zones are operating within spec. We checked power, I/O, SSR's, thermocouples, and exhaust, but the issue remains. We did not check resista

I'm attempting to perform power analysis on my target, which operates at 3.3 volts. The average current while running is around 140mA without the resistor. With a 5V power source, I utilized a 10Ohm resistor as a shunt resistor. The shunt resistor w

Messages indicate bad battery on EPC-5 CPU board, not SYS68K CPU-30. You have to fix that first. What kind of hard disk is installed? EPC-5 boards support small disk sizes, so sometimes , if larger disk is used, users "trim" reported capacity to lowe

How fast do you use your OSP boards? We don't use them but if we did I would want to try and use them the same day we open them. They are cheap but do not store well. Tin/Lead paste spreads much better than ROHS paste. If you can not always reflow

USC PArk is your underside stencil cleaner. The camera pushes it back and a magnet grabs it and holds it back. Ours did this many years ago. I pulled the rear cover and initialized the machine, when the camera pushes the stencil back, grab it and

If the part makes it in the right location by leads touching the paste in the right location, you have very few places to check. 1. Check parameters like air kiss, or some timings you can keep the part down in placement position for a while. Sometim

The boards were just a little larger than a SOT8. IIRC we had a pizza slicer type depanelizer and it wasn't too bad. We just did enough to populate the bare PCBs we had. Where I am now a customer has us put a QFP and a few other parts on a SOW28 f

For future readers - just needed a little bit of lube. Many thanks to Michal & the staff @ Trans-Tec (USA) for their excellent support, as always. Please see attached. For our (dated) machine, the black dial would turn only after hitting the gym
