Hi TechNetters, I'm trying to determine how many PCB's will fit comfortably on a standard sheet of laminated FR4. This is for a single sided rectangular board 2.5" x 3.5". Here's what I need to know: 1. How big is a standard sheet of FR4? 2. How much room do I allow between each PCB for routing bits? 3. How much material do I need to allow for around the edge of the sheet as unusable? Thanks in advance, -Michael Hiteshew --------------------------------------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt delivery of Technet send the following message: SET Technet NOMAIL Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------------
