Jim, the MC68340 was on .015" centers, with 288 pins. I hand
soldered a lot of them on the test line, and changed a few by hand
rather than wait for rework to use their hot air station. Solder
bridges are no big problem if you run a thin bead of RMA flux down the
row, then put a drop of fresh solder on the tip of the iron. Hold the
board at a 45 degree angle, then run the drop of solder down the row of
pins.


Is the board tilted so "down" goes crossways over pins, or in the
direction that the pins point?

About 45 degrees; a little of both, plus about 45 degrees to Z. Think,
corner of board on bench, tilted back so you're looking straight at it
from your stool.

Cheers!
Rich


I think good electronic techs and modelmakers are greatly under-rated
and unappreciated contributors. They sure were at the corporation
where I worked as an engineer, manager and research puke for many
years.
