Hello all, I am trying to find companies that can prototype devices of this type: 50 micron wide, 50 micron high copper or gold wires patterned on insulating substrate - could be silicon, glass, or whatever. Trace spacing >50 microns, chip dimensions 10 mm by 10 mm. Ideally I would provide the layout and chips come back in the mail. Does anyone know what are the most reliable / fastest turnaround companies for this kind of work? Thank you, Dave Kielpinski, Ph.D. Center for Ultracold Atoms Massachusetts Institute of Technology phone: (617) 452-3180 fax: (617) 253-4876
