We're looking for a contractor who can support high volume production of 0201 passives and 1-2mm csp's to create 4mm sq. RF modules as well as mold cap capabilities. Any leads would appreciated.

Nelco was developed by Park [ http://www.parknelco.com/parknelco/highspeed.htm ] Without fairly involved testing, you may be forced to rely on a c of c from your fabricator. Although, Park may be able to give you a lead.

IPC-2222, 5.3.1 defines the parameters of making scoring cuts and the tolerance of the cuts, but does not specify the cuts. Our spec for 0.062" thick FR-4 boards is: 0.018-0.024"

Many shops require levels for typical component packages on FR-4 or a like substrate to be 2, 9, 15, 1 and 10 mg/in2 for fluoride, chloride, bromide, nitrate, and sulfate respectively. These levels can change for Medical or Automotive.

An old quad 2C/4C with a workholder will probably fit all those numbers. 2Ft is pretty long though and that might be a little too long. Machine price range is about right. Programming is pretty easy. Good luck

Thanks for the info. I was having trouble finding SMTMaestro until Phil posted a link. I guess it is a little dated. Here is a quick demo of SMTMerge. https://youtu.be/nHe3-8kVHk4 Cheers, Bruce

1.Yes but you want specific SPI & AOI machines. Same manufacturer can provide both. 2. Yes but not as well as an SPI machine. 3. Don't understand question. 4-7 You should do your research, or hire someone with the expertise you require.
