I guess I would rather spend my time demonstrating why a 20K machine can't do its job and how it is really costing the company money. Maybe its unfair to blame the machine. Often the problem is the team surrounding the machine. Poor maintenance,

If your problem is happening part way through the calibration the problem might be there is too much friction from your Y-wagon. Measure the friction on the Y-wagon using the service program if it fails or if it is near the max allowed try oiling up

I have seen a similar problem once about 15 yrs ago. Someone decided to try a water wash flux for tinning wires. Bad idea! The wires were dipped in the flux, then in a solder pot. As the lead tin's it forces the flux in the strands to move up the wir

the original question was: Please give me some guidelines on designing Stencils for Fine Pitch. which i did however, 40% fallout for solder shorts this could be caused by many other processes having gone wrong before, i.e. type of solder paste
