Hi Chris, At last months Phoenix Designers Council meeting Hadco Corp ([log in to unmask]) gave a presentation on microvias with examples, I don't know if Hadco is on your list or not...... Ted Nathan PCB Designer Celwave,Phoenix ---- DesignerCouncil(a)ipc.org's Message ---- I am presently pushing the use of MicroVias to the management here at LXE. One issue that will be raised is how prolific the technology is. Sole sourcing or even having just a handful of sources is never a good sell. Can anyone help me compile a list of MicroVia PCB vendors? TIA, Chris Taylor Senior PC Designer LXE, Inc. 125 Technology Pkwy.
