Thanks! Will post a few more beauty shots when I retrobrite the case and keys. 8Mhz I think.Maximilian wrote: ↑Thu Feb 28, 2019 11:46 pm Always nice to see someone taking the time to clean an old machine up.
I'm a bit of a ST noob but is this a 8 or 16Mhz 68000?
Also where are you located.
(if I may ask)
I'm sure you're aiming this at the orginal poster, but I'm just using this simple thermostatically controlled iron:Maximilian wrote: ↑Sat Mar 02, 2019 1:05 pm What kind of soldering iron/station are you using?
Normally repairs will go pretty smooth with 380C, when using wick i also wick from the top (mostly C64), that cleans most of them up nicely.
Both actually,
Completely agree with the above, ST boards are quite hardy, but overheating when desoldering can easily cause pad lifting.Maximilian wrote: ↑Sat Mar 02, 2019 2:47 pm
If a ground or VCC pin really wont budge I always:
1. Try to remove as much solder as I can from the top and the bottom using good solder braid and sometimes try again with fresh solder applied,
2. Add a little solder to the offending pin.
2. I unsnap all the other pins with a dental hook, and then I heat the offending pin while taking the chip out.
The above only gives me any grief if someone else had a go at it, mostly because they solder to long or use a temperature that is to high and the pads come off.
