My boss had some problems with this at his old company. Aparently if you solder your DIP components starting from the center pin and working your way out the solder joints are more resistant to flexing. The qualitative test is twisting the board: if there is a lot of squeeking then the board wil be prone to failure.
I did something that caused some of the shift registers to get hot, does this mean that they are bad now?
I got it figured out, turns out a couple of connections were shorting out in my ribbon cable connectors.
and when I was having the shift registers over heating, it turns out that my ground connection disconnected, and it must have been grounding through some of the pins in the SR's that I had grounded, like the select pins.
Thanks for the suggestion on the dip's, I'll have to keep that in mind next time
