Is it really a chip out or broken? Is there any way you can post a picture through Steve's site? Kat >>> [log in to unmask] 12/23/02 07:22PM >>> Shawn, I believe this phenomenon is called "draw-bridging", and my theory is that it's caused by the contraction of too much solder in the solder joints pulling the component's end-caps apart. I have seen two or three examples of this kind of failure on 0603 resistors, and in each case, I found that there was excessive solder in the joints.

This affects the resistance of the component requiring replacement. Can anyone tell me what the most common cause of this chip out is?
