Topside heatsinks can be removed with hot air to soften the epoxy. White epoxy will dissolve in acetone, not sure yet what cuts the black epoxy. Different epoxies were used on different batches.
As for layout, not really sure offhand. I'll check something over and might post a picture later.
Cool Sidehack, any help would be great.
I might try some de-potting agent on the black epoxy im sure we have a few gallons left here from when we were repairing some weatherproof control boxes.
As for the white, Ill pull the home made sandwich toaster hot box out and cook the boards in that for a while see if that softens them.
I dont really want to bugger up the pre-heater with dripping epoxy as my boss might not be to happy about that.
Ill have to cook up another batch of acetone with some epsom salts to remove the moisture from it so I have no moisture involved.
If you have anything on the ASIC locations that would be a bonus or its gonna be a few long days of track tracing to work it out.
I have the data sheet on the ASICS so hopefully the chained data bus is an external layer on the board, but more than likely hidden away inside some place.
Thanks!
