Hi there, This could sound a little fun for a group of people like you. I 'm manufacturing PCB's single side and double sided and I don't have the IPC manual. I have been in this forum for a little time and I have heard that lot of answers to a problem in PCB's manufacturing are in this manual. I will appreciatte a lot if somebody give me a phone number, fax number, address, E-Mail or anything else that can help me to get this manual. Thanks for your time EDUARDO TOVAR DISEŅO DE CABLEADO IMPRESO --------------------------------------------------- I don't know who iniciated this forum but... What idea!!
