- You use a low wattage iron on microelectronics for Gods sake! You
- need to go take a class in soldering. Liquid flux is used to ensure
- the solder heats and flows evenly. There is no substitute for proper
- equipment and materials. If you don't have them or can't get access
- to them take it to a shop and have it done right.
-
- Besides the A4000 has a multilayer board and you need flux to
- ensure the solder flows evenly to the contacts on both sides of the
- PCB. A high wattage iron will burn the PCB, cause the runs/tabs to
- lift and FRY sensitive semiconductor devices.

-
- A computer is like any other piece of hardware, be it a car or
- what ever, a little preventative maintenace goes a long way. You
- should open your Amiga and blow the dust out every couple of months or
- so. More if you live in a Hot humid enviroment as the dust will draw
- moisture and cause corrosion. While it's open check the battery for
- corrosion ect..

- You obviously don't have an A4000. The ones I have seen and
- replaced batteries in were all soldered to the motherboard. Would you
- like the P/N of the battery to prove it. I just replaced one last
- Friday in an A4000/030.
