The new universal guide replaces .7 - 1.8 mm tape covers. Fuji no longer makes the slitted type tape covers. How can the tape guide be mis-centered ?

We are wave soldering some fabs with a lot of unmasked trace area along the edges. The trace area is solid copper covered with tin / lead, no masking, no components along the edges, same on solder side and component side (goofy board design). Inste

We occasionally have this problem where the nozzles peck little holes in the component overlay tape causing it to break. It only happens on universal tape covers. We see it on our CP4 and CP6 machines. Has anyone else experienced this ?

Are these covers repacements for the tape guides? If so in retipping many thousands of cp6 nozzles we see that the window in the tape guide is often miscentered and the needle tip rubs on the same place every time it picks. I expect the miscentered g

I just checked a hand full of scrap nozzles and the scuffing is usually on the right or left of the needle. If you have the cross pin facing you and looking down on the nozzle most of the scuffing or wear was on the left side, sometimes on both sides

My guess would be trapped flux continuing to be active after soldering. Is the tarnish there immediately after exiting the machine? Do you remove the mask and wash right away? If the solder is reflowing under the mask on the component side it wo
