I am trying to update and standardize the notes that appear on our printed circuit board fabrication (drill drawing) drawing. The current drawing has over 20 notes detailing things like hole registration electroplating thickness, wrap and twist ECT. I would like to reference one specification that covers all aspects of the board fabrication and eliminate all the specific notes. Is there and industry standard on what needs to be specifically called out on the fabrication drawing and what is the best specification to reference (IPC-A-600?) for fabricating 4 layer commercial grade surface mount PCB's. ############################################################## TechNet Mail List provided as a free service by IPC using LISTSERV 1.8d ############################################################## 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 web site (http://www.ipc.org/html/forum.htm) for additional information.
