Hello, so basically I've been having trouble with parts popping up as they are being inserted into the PCB. It happens at random and I've gone through multiple rebuilds and tons of adjustments and still cant get a clean run. I've tried raising the cu

What I'm thinking is that your cutter/former (or whatever the "boot" shaped assembly is called, that provides the dies for cutting and forming parts from the tape) could be worn, dull, bent, etc., and once in a while you get a lead that doesn't enter

Hi, Thanks for the valuable feedback. Agree with you. 1. We have similar component on both the side of the board. 2. The component fall was random like 4 out of 100 components.But last build it has increased. 3. Applying glue dot is option , bu

I have a Heller 1808 Reflow oven with the chain that has the edge hold to keep the boards off of the mesh belt. The feed end was more narrow than the exit end, and some boards would fall off. So we adjusted both ends to be the same. Well now, when

Are they getting stuck inside the oven or at the very end? If thermal expansion is the problem the boards would be getting stuck in the reflow zone since that would be the hottest and therefore the point where thermal expansion would be the greatest

Not sure how the lead screw drive gear is locked in place but is it possible that it's slipping in both directions (when driving the rail both forward and backward) and then not catching until after the other end has already moved some? You could h

I have a similar over and both in and exit should be the same distance apart. You can contact Heller for help. If you have maintenance manual if should tell you how to adjust the timing chain for the lead screws, I am assuming your over have three le

Hi, Was wondering if anybody has any experience with F5 with the conveyors will work sporadically. If I put a board on the input sensor in which it sees it will work, the next 5 minutes it won't work. Could this relate to the K2 relay, if so does any
