Sure, you can use X7R dielectric ceramic capacitors on mixed technology boards. You need to be aware of the limitations and design and control your process appropriately. Continuing: * BIG cracks show as hard failures * Small cracks show as a leakag

I would assume you are using a depanelizer to cut the boards apart? If not you should be wheather its causing your current problem or not.

Is this a new design or have you manufacted these in the past without a problem. we manufacture ceramic arrays from X7R and COG, X7R has a differnet dialectric strength so higher capacitor values can be achived. With the introduction of RoHS the term

To recap: 1) The machines use laser centering, not mech jaw centering. 2) The X7Rs are scattered on the board, center and edges. Improper de-panelization would favor damaging the parts near the edges of the board; this is not the case. 3) Both ROH

has anyone used or trialed the SACX from Alpha, from reportes and studies carried out it seems that its a go between SAC305 and SN100.
