Sorry for stating this incorrectly. It should been: Bow & twist for bare boards and panels: IPC-A-610 Acceptability of Electronic Assemblies, 10.6: 1.5% for PTH only and 0.75% for SMT, acording to test method TM-650, method 2.4.22 IPC-6012, par. 3.

Do you still have the vacuum plates in? If so, you can set the grid-lok up in the "fixed mode" (not sure what they call it,where it won't set for each board), then you could run without side clamps and the Vacuum should be enough to keep it from movi

Rob, I have talked about this on the forums before. I have since then gained much more experience on this issue. Some things to look at : 1. The X/Y/Z table must be indicated flat. (See the Fuji manual for specs.) 2. Your Z-origin must be correct.

Thanks to all for the info. The ideas to correct the situation are all excellent and if we see any more boards from this source with this condition we will know what to do now. In the end however, the real questions we are trying to answer are, 1.I

This was a rather intersting little project to work on due to the fact that I had such a variety of components placed in SMT ( your regular 0402 passives, ,BGA's Qfp's ,TH and SMT connectors ,plus the pesky micro BGA) I ended up with a 5/3 mil electr

You could probably put a 1/4" plate of steel over the aluminum and make some shorter magnet pins. I think the factory upgrade was $3500 to $4500. Its hard to justify the cost based on saving maybe 5 minutes a set-up for an operator. But your lines wi

Hi Bert , I dont know much about IP , since I partnered our Fuji CP 6 with Siemens .At any rate, can you check your flat ribbon cable of your Ip's Head. I assume there one wire that is nearly breaking. During movement, head servo controller experie

Thanks davef! We found some SOIC & QFP with all leads having toe down problem. The heel fillet unable extend to the mid point outside bend. Do you have solutions for the problem? I have a question: How about the normal gull wing lead which is flat &

It is possible to vary the length of lead during auto insert. However, it requires software and mechanical adjustments. Universal equipment allows small changes via software program for lead length. To change angle of clinch involves a mechanical a

The proper method is to load a flat plate into the X-Y-Z table. The plate size should be as large as the largest board you run. Indicate the entire area of the plate with a dial indicator. I don't remember the exact spec, but try to stay within .2mm.
