Hi Hugh, I have the following suggestions for your survey. 1) Product Mix- include controlled impedance boards 2) Design Capabilities - include what file formats are accepted for PWB Data (What version of Gerber, drill files, etc.). From a survey design point of view, I would also explicitly list several design and manufacturing software tools in the hope of eliciting better responses, i.e. (I hope I can name names on Technet- if not, please flame me offline. Also note, this is just an example list, there may be others!) ACCEL Technologies AutoCAD Best Proto Cadence CADint PCB Data I/O (Synario) HP RF Board Designer Intergraph McCAD Mentor Graphics MicroSim OrCAD PADS Software Protel Ultiboard VeriBest Viewlogic Visionics (EE Designer) Xynetics Zuken-Redak 3) Special Technologies - include plugged vias. Hope it helps, Cheers, Andy ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC's web site (http://www.ipc.org) "On-Line Services" section for additional information.
