0603 component drift

0603 component drift | 11 November, 1999

We are having a continuing problem with 0603 chip capacitors not centering themselves on the pads during the reflow process, causing an open condition at one end. Does anyone know what can be done to alleviate this? Thanks much.

Gary,

We've experienced the same problem in the past, and found that moving the stencil apertures closer together solved the dilemma. This was a much easier solution than having to redesign the PWB.
