Hello, We have a MPM UP2000 HiE printer from 2000, software version 7.2E. The PC board is not booting anymore (black screen), no drives spinning. It's an Advantech 486SX version. Question: would a Pentium 3 SBC (Single Board Computer) with ISA

Hello Michel...this might be a bit of a battle finding the low thermal EMF material that you are looking for. The first one that comes to my mind is Bismuth Selenium Telluride, with either a nickel or cobalt doping agent. Silver went away from this

This style gave me grief as well. The problem is the way the part is manufactured leading to an unusual pad configuration. When the part is placed on the PCB there is no pad wrap under the part, the pad is 90 degrees to the board. The datasheet shows

Component manufacturers subject their lots to thermal / reflow testing per IPC /JEDEC STD-020. This involves running the parts through an oven 3X with a peak above 260C. I am not certain if passives go through the same test (theoretically they shou

Colleagues, I have a JT-620L Wavesolder machine (Made by JYI DIANN MACHINE) that experienced a power fluctuation and had the factory programming wiped. If someone would be so kind to read the settings on the (4) VS-606V7 controllers I would be very

Try these things: 1. Reseat the cards (with power off) and Reboot the machine and see if the errors clear. 2. Unplug the nozzle changers and try to reboot....sometimes they can mess up the system. 3. If all the above fails.....the b-rams in the card

We have worked out as a guide formula to help us calculate this. As we have products that range from 5 unique pars to ~300 parts it is tricky to answer clearly. we worked out an average time to change our feeders at 3 minutes (this includes removin

Got a failure while starting up our GSM, and hoping you guys have an easy fix that we're not seeing. We're getting a Timeout waiting for nozzle changer vacuum buildup. It seems to be occurring on head 2, during nozzle change. We've reseated all of

I have seen a couple of references to Black Tar, Not Black Pad. Apparently, it occurs only on the solder side of PTH's after wave solder and primarily on the edges of the land. It is characterized by a black coloration (Not Ni corrosion?) and non-wet

Hola Grayboard, I've had the same situation with these components, I changed the stencil apertures a little bit and use a stepped stencil (5-6mil), after some trials we were able to get decent yields, but we still had some failures, what we discover
