Believe it or not Gang...(I sure didn't!) I did locate a source for a P.T.H CEM manufacturer quite some time back ! Itaucom S.A.! They were really price competitive with the International PWB market, and are located in Brazil, S.A.. Their samples looked very good, and I even obtained a video of their facility. Don't know the Reputation, or capabilities, but they were building for some large companies that desired the benefit of low end materials/labor (mostly consumer grade products). *** rep. firm: Purdy Associates Robert Mericle fax 303-790-2230 Englewood, Colorado. Have fun. Les Beller Echostar Comm. Corp. We have used it for single sided boards and we found the Z expansion to be excessive. I would suspect plating vias would not be very reliable once thermal expansion started. I recommend speaking with your board vendors as they should have reliable data to go by. -Ed Current ---------- From: Barry Olney[SMTP:[log in to unmask]] Sent: Monday, August 05, 1996 6:41 PM To: [log in to unmask] Subject: CEM1 Substrate material Has anyone used CEM1 substrate material? Can CEM1 be plated through? I believe it is a low cost material that is used in the mass production of comsumer products. Holes are punched rather than drilled. Thank you in advance for your help. ___________________________________________________ Barry Olney http://www.icd.com.au Managing Director In-Circuit Design Pty Ltd Ph: +61 3 9205 9595 VeriBest Solutions Centre Fax:+61 3 9205 9410 Suite 211, Princess Tower Mbl:+61 4 1117 0827 1 Princess Street, Kew, VIC 3101, Australia Email:[log in to unmask] ___________________________________________________ ************************************************************************ **** * The 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. * ************************************************************************ **** **************************************************************************** * The 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. * **************************************************************************** **************************************************************************** * The 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. * ****************************************************************************
