Hello there my fellow AmiBayers
today I got a smige of time to do a couple of small things, one of them was to do (part 1) of arnljot's MiniMig repair
I also promised Imnogeek a photo log =D
Part 1: removal of the RAM chips
With the two chips removed and the are cleaned we can see the damage is minimal.
However the damage is substantial enough to warrent some jumpwire
When viewed from this angle
Part of the pad has been vaporized as such its not long enough to catch the feet of the chip.
What happened to those chips? here they are -
I dont beleive these will be any good, due to the heat that was placed on the pins when the pad was vaproized - fortunately arnljot has provided more =D
Spartan trouble?
I noticed a small blob of solder bridging two pins on the Spartan chip.
I honestly dont think it should be there and likely a spit or drip from a soldering iron.
If anyone has a working MiniMig can they confirm that this bridge should or should not be there.
okay..... part 2 tormorrow : new chip and test
