Hello bphillips, I'm not surprised you're having difficulties with this size chip. As technology advances in product development continue to shrink package and real-estate size, the equipment and its automation must continue to perform it's desired function. Only machine manufacturers that specifically quote 0201 placement capability are likely to actually place the chips. In most cases, machines are not capable of placing 0201's without modification and regular maintenance plan in place. To validate your equipment, you'll need to obtain highly accurate glass plates and design a measurement plan that places the chips in pre-determined locations (based on ASCII or Gerber data X and Y positions). With a measurement plan and a suitable measuring system, you can measure the deviation between actual position and desired location. Only using a software program to automatically calculate the deviation and measure against the machine specification can you determine if the machine is statistically capable of accurately placing 0201 chips. Let me know if you require additional assistance. Thanks!
