Doug, ref: IPC-T-50 "Terms and Definitions for Interconnecting and Packaging Electronic Circuits" The normal industry practice of distinguishing between them is as follows: Printed Wiring Board - A printed board that provides point-to-point connections, but not printed components, in a predetermined arrangement on a common base. Printed Circuit Board - A printed board that provides both point-to-point connections and printed components in a predetermined arrangement on a common base. A PWB or a PCB with components mounted on it is commonly referred to as a Printed Circuit Board Assembly (PCB Assembly), Printed Wiring Assembly (PWA) or more recently as a Circuit Card Assembly (CCA). ---------- From: TechNet-request To: technet Subject: PWB and PCB??? Date: Monday, 21 October, 1996 11:22PM Is there a difference between a PWB - Printed Wiring board and PCB - Printed Circuit Board in the industry? Is it safe to assume (uh-oh) the PWB is the bare board and the PCB is the PCB w/components, i.e. a PCB assembly? Does anyone out there make a strict division between the two this way? ******************************************************* Doug McKean [log in to unmask] ------------------------------------------------------- The comments and opinions stated herein are mine alone, and do not reflect those of my employer. ------------------------------------------------------- ******************************************************* *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * *************************************************************************** *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * ***************************************************************************
