We also encountered the crack case in multi layer Ceramic Cap,0603 after touch up. Most failure were on the terminals. Previously, we used 0805 instead 0603.that time, failure were very few.

Yes, it is very true and very clean SNAP!

suggest you check the preheat conditioning in the wavesolder process is sufficient, as this is the main culprit for micro-crack CAPs ?

Please describe the location and appearance of the crack

check your de-panelling process if you are using break-out tabs or V scoring.

Hi ya'll, We may be getting some business here for a small (2" X 2"),ceramic substrated, double-sided SMT assembly. I've done ceramic substrates with SMT in the past, but not double-sided, and as packed as this thing will be... My question is, can

When it works right, it's a beautious thing. => When goes wrong, you have one board with some of the other board's material, not too coo. Scribed and broken ceramic has bad-butt sharp edges. You'll feel this sticky stuff on your hands, look down,

I've seen numerous incidences of mirror image cracking under endcaps in high dielectric material ceramic capacitors due to thermal cycling. If the cracking is deep enough to extent through the plates you can get breakdown and shorting. Section the ca

150*C/min * Determining the distance it takes to lower the delta temperature at the current conveyor speed: [150*C/min]/[25 inch/min] = 6*C/inch * Calculating how much of this 6*C/inch would be spread along the length of the 0805 capacitor: [6*C/inch
