72 different part numbers, 53 being 8mm, remainder being 12-44mm and 3 tray. It may be low but anymore than 100 and you give up throughput because of feeder locations. And thinking about it, 70-90 is low for a low volume high mix line. I guess if I w

Assuming you are working to IPC standards, are you working to Class2 or Class 3? Class 2 has an exception to the 75% barrel fill (para 6.3.1, page 6-7). "As an exception to fill requirements of Table 6-2 on PTHs with thermal planes or conductor

Dhanish, on a CP6 if you have skew problems or missing parts begin by a center check on your smalls nozzles. If all nozzles goods, you will have to check the Z zero of the table, this is the pulse count of the z axis (table height) when the turret is

We have a DEK 260 with a intermittant table align stepper motor problem. The machine will work fine for awhile and then one of the table align motors starts either moving hapazardly in small increments back and forth or vibrates as if it wants to mov

Optimizers for pick and place machines are very specific for the type and model of the machine you are using. A chip-shooter will run at optimal speed with the same type of nozzle and minimal table movement. Most X-Y tables have a faster X-axis than

Could I get some help please? I have a Heller 1700EXL, 7 zone oven and I'm trying to figure out a better way of off-loading my completed boards. What I have now is simply a small table at the exit of the oven with about an 8" drop from the top of

I would use an SPM if it was my choice(for a semi-auto). You should be able to get a used one with vision for less than 10 grand. I would not use one without vision for fine pitch, although you probably could get away with it. The first few they made

Fastek will get it done with 2 machine and 2 shifts. 2 shifts would need to place 50,000cph. One CP643 with both device tables set could get it done. Having it panelized in 50's, you would need to print 50 panels a hour so get a auto cleaner on the p

I have been using overall combined DPMO of SMT PCBAs as a performance metric. All defects are recorded down to component location and defect category. The resultant defect data table is analyzed with detailed pivot tables, defect type and defect loca
