Kathy/Alcon: - I believe that the number of five (5) being applied to repair actions is a misapplication of the old "simulated repair" or solder float test that was applied to pwb test coupons in accordance with Mil-P-55110. Seems to me (reaching back into the catacombs of grey matter) that when testing a pwb coupon, the pwb was considered "good" if it did not exhibit any lifted pads after 5 simulated rework/repair actions. Based on that test, industry observers concluded that it was OK to rework/repair any connection up to 5 times before it left the assembly line (not exactly what DOD intended). No longer have a copy of 55110, but I am sure there are those about who do have copies and can confirm/deny my recollection. Regards, Jim Moffitt, Moffitt Consulting Service, 317/773-5570
