It is a serius problem with that mulilayer ceramic caps! In automotive applications you have to use 2 in series for one single cap. During depanelizing you create a mechanically wave in the board, so 3.. 4 mm. Best way is not to do such a wrong desig

If you can't get rid of all caps near the edges, don't forget Neil's advice above regarding parallel vs. perpendicular. I have seen a 90 degree rotation make a huge improvement in the reliability of some caps.

Yes you are correct Barry. The Suction tape provides a flat surface for the PNP nozzle to pick -up. In some cases I have seen a plastic "cap" ove rthe pins to provide the same thing. The cap can be reused. Both require, unfortunatly, manual removal

Hi, Is there any accesory we can get from my data to place caps vertical on the board but are horizontal in the reels? Is taking to much time hand placing the parts, we would like to automate

I've seen cracked caps due to de-panelling on caps 40mm in from a board edge, if the cap lies on a stress line it can be cracked quite far in, i'd go with the other replies and make sure you use a "pizza cutter" type de-panelling machine for v-scored

| I am trying to program some tant caps on my universal 4785 chipshooter and it just won't take. If anyone has any experience with the 4785 please let me know. I have programmed some pretty tough parts in the past and I know the vision on the 4785

Can someone explain what ageing means in terms of chip caps. Capacitor vendors state 7% per decade hour or 2-5-1 per decade hour. What does this mean? I think capacitor values lower over time but what is a decade hour. Thanks, Chris

Hello, can anyone recommend a conductive epoxy for printing and 0402 cap attach? We have some short issues underneath the 0402 caps with our current epoxy. Any input is appreciated. Thanks a lot...

How many times can I reflow SMT components such as SMT Ceramic Chip Caps (0603 and 0805), Res Caps, TSSOP's, SOIC's Tant Caps etc? Will I have a problem exposing them 4 to 6 times of reflow? Will I damage them? What will go wrong with that process?
