- Removing a 40pin DIP from a multilayer board is easy to do if:
-
- 1 - you have some degree of soldering experience. (No, pick it up
- from the *other* end!)
-
- 2 - you don't care about the 40 pin device you are removing.
-
- The method that I use is similar to the one described, but taken
- further. Clip all 40 pins off of the DIP as close to the package as
- possible. Now, simply remove one pin at a time from the PC board.
- This is not a difficult task to do as you are only attempting to
- remove a single pin at a time. Just get a "solder sucker" and have at
- it.
-
- I can't imagine how you could solder the new device's pins to the old
- pins that are left over since the old pins no longer have any mechanical
- stability "floating" as it were when you heat them with the iron.
