Steve,
This is a problem with most Pick and Place machines.
Although Fuji has a nice kit full of inserts, it's a real pain in the neck (not the verbage we actually use on the floor!) to find the inserts, set them up, and pick repeatedly.  One problem we found is that tube designs change from supplier to supplier, and, inserts are not available for all packages (as you pointed out).  

We have Mydata P+P's and have run into similar issues.  

One portion of the solution is to try to get these parts in Tape and Reel (or Tray).
Another portion of the solution is to invest in additional feeders and keep them dedicated to repeat jobs, or, jobs with similar component packages.
Lastly, you may want to consider abandoning the use of the inserts and simply modify some tubes which can be reused. You tubes become your hard tooling.  My only warning with this is that it will require the transfer of parts from tube to tube and you may need a "tube-to-tube" transfer interface tool to prevent bent leads.  Oh....and every now and then, if someone is not careful, they may cut themselves when cutting the tube to size/shape with an X-acto!

Subject: [TN] High Mix Part Handling


A question about processing boards in an SMT assembly low volume, high mix
environment. We spend much of our time setting up and breaking down kits as
our average kit size is only 25-50. Much of this time is spent with IC
parts in tubes (vs. tape and reel or tray). SOIC's were once the high usage
parts, now SSOPs, TSOPs, TSSOPs, MSOPs, etc. are becoming more prominent.
With Fuji IP machines, we seem to be spending too much time trying to find
vibratory feeder inserts that will accommodate these new package types. I'm
trying to find a way to eliminate having to buy multiple inserts of all
possible package types. Is there something out there that streamlines this
process that I've yet to see???? Any input would be appreciated. Thanks.
