Design changed? Posted by Bill Homer [Email] (#3427) [Profile/Gallery] (more from Bill Homer) on Wed, 19 Jan 2005 08:04:00 In Reply to: Re: Not a poor solder job - a design issue, Wingerr, Tue, 18 Jan 2005 13:30:08 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I just repaired two of these relays (nice to have a spare!) and noticed that one of them had a physical connection between the relays and the bottom of the relay package, i.e. metal tabs twisted into recessed mounting holes. There are letters stamped on the sides which probably indicate a date code - the one with the tabs is later in the alphabet, which may indicate that they tried to address the solder joint issue. Obviously it was not totally effective, as I had to resolder it.
I recommend removing the old solder with solder wick or a vacuum pump, as the solder that was on the board had crystalized(?) and did not want to flow properly.
