Who is using two sorts of tin in one selective soldering machine with to solder pots? So then the soldering program selects the correct pot (tin). What are the risks? Adding wrong tin in the wrong pot. Mixing up the nozzles?

Hello, I'm in desperate need of a boot up disk for my Electrovert Omniflo 5 oven. Type: OMNI 5SE Date: 5/98 I would like to purchase or borrow. Or maybe someone can point me the right direction it would be greatly appreciated. Thanks

Where I was before, someone started keeping the scraps because he wasn't sure where to put them. Then everyone did and it built up. We had a couple local PCB suppliers and asked what they did. Landfill. I think FR4 with masking isn't amenable to

Yea I thought basically the same thing. Possibly increase our own costs meanwhile the FR4 still ends up stuffed into the ground.

These machines are known for this. Keep reseating the chip on the display board. The mylar display looks pretty bad and may need replaced.

I spend several hours resetting both chips and no luck. I have a question: The lcd not displaying could be the main controller board? Does anyone sell parts for this machine ?

Make sure the pins on the chip on the main display are not bent or tarnished...i have scraped the bottom of the legs before. I would try Reprint in UK. I think they still have parts.

Do you recommend soldering the chip to the available smd surface pad? Did you mean https://www.sigmaprint.co.uk/? Thanks

The mylar is just the keyboard and has its own connector. All the keys seems to work well (the lcd pcb has some leds and they blink when I push each key). The lcd is soldered on the display board.

For some reason i remember reseating the mylar and it working but it was probably just lucky and fixed a bad connection somewhere else on the board. I know we also reseated the ribbon cable.
