My first guess is that the plating in the barrel (via) has failed and allowed laminate/epoxy egress into the barrel and out to the surface of the board. Just a guess based on the picture.... 'hege

PCB Supplier made an EDX anaysis, the found a chemical trapped in the holes, and some burnt burrs, according to what they say this stains are over the solder mask & silk, so they do not affect functionality.

Could anyone help to connect a FUJI CP42 machine to a conveyer with stanard SMEMA? CP42 has 2 wire cable and small female connector label SMEMA (Not fit with stanard SMEMA). Thank you for all your help, -Michael

It was fun and easy to be a Chiefs fan 1991 to > 1993. Not so much nowadays. Yes it was. This was the time of Joe Montana's last hurrah. An exciting time to be a Chief's fan.

Just an FYI regarding the 8080 buffers: When you replace the lithium battery in the display module, replace the one in the PLC as well. Of course, you will need the machine turned on when replacing the batteries.

Hello! You need an upgrade on AMS3.0 to use it with Windows 7. And then you need a dongle for every PC you want to use it on. And with that step ypu dont need a floppy anymore you can register the machines with usb stick or over network. Christian

I will treat it as any other BGA. Drill a hole in the board, put thermocouple and do your profile.

Unless you use the method Evtimov described, you will be guessing. And yes metal topped BGA's take heat differently than PBGA's

Can you give me any more information on how they take heat differently? Do they get hotter? Pull heat away from the PCB? Heat more even and pull heat away from the surface? Thanks, June
