I have several reels of components I purchased from Chinese source. During pick and place, the tapes keep breaking (they tear diagonally along the reel). I notice the tape is very tight if I try to pull through manually. I tried several over 12mm fe

We're not real clear about what you're trying to discuss, because most capacitors are packaged in epoxy with a solderable termination on each end. But lets throw a couple of ideas at the wall and see what sticks. If this epoxy is: * From the capaci

Hi! From your post, it seem like the wave did not really touch the component. You probably need to get the both wave height correct and that it hits the component.It is normal for solder to come through the PCB when using chip wave. The through-hole

Unfortunatly there are too many variables to play with that you can't make a general rule for the vibration time. However, I suggest you increase the vibration time and lower the vibration force ( AC voltage ). For an SO 8, I would use 600 ms for an

hey, I'm having the same problem as you are. the component is sticking on the cover tape prior to pick and place. hoe do you address the problem??

Usually Static in the tape will cause the component to stick to the cover tape as opposed to staying in the pocket. It sounds like you have another problem. But anyway, here is what we do when we "think" we have an ESA problem. We place the compone
