Some cracks are really obvious,straight down the middle of the capacitor.Some are slight hair line fractures which fail at ICT.In all cases seen,all cracks are through the centre of the cap.My worry is that there may be some which have fractures and

I have experienced this same problem with CECC Type caps, in all sizes. One cause, which may have not been explored is the component may hav been cracked before you placed it 1 in 300? Hmm..I did this on our products that were showning atleast 5 per

Have been through this before and we resolved our problem as follows: 1.Make sure that the length of your board support pins on Your HSP is correct. On that machine the board support pins depends on the board thickness (+ - some tenth's of a mm). It'

I am wondering how to move from hand soldering our ceramic caps to doing a reflow type process. The reason for the change is too many cracked ceramic caps. I have asked our vendors to assemble our boards via reflow but because of our hardware (swaged

Cracked components will occur when the component is stressed. The only way to stop this is to not stress the part when removing the score. This can be done by fixturing the board top and bottom so it doesn�t bow when breaking off the breakaway. Vi

Break off the break-away? If you are going to fixture the board why not just buy a cutter?

I haven't heard of heating boards pre-depanel either. We have done extensive studies on cracking of ceramic caps close to V-scored edges and have decided to have our board vendors pre-rout any areas with caps close (
