Howdy All, I am new to this list and I thank the folks at 3M's Microflex division for pointing me here. Y'all can blame them later after reading this lengthily post... The acceptance of my lousy prototype was excellent, so I was looking at ideas for a more robust and fine-tuned design using a flexible circuit. I need a flexible PC board operating at 12v DC. Size is about 1/2" x 6" or 8". The mounting is static, but the flexible shape is required because of the variety of mountings. Also, the outdoor environment will be greasy, dusty, wet, cold (-50F), sunny (UV) and hot (120F). So, it needs to be durable. There will be no direct abrasives. The board and protection should be no more than about 2/10ths thick. Is there something like that out there? You've probably seen that "soft-touch" switch rubber used on keypads. A slightly firmer version of that with copper cladding (or something to etch) would be about perfect, as long as it's tough stuff. Thanks in advance and I appreciate your guidance. - Scott (775) 849-2030 --------------------------------------------------------------------------------- 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 ---------------------------------------------------------------------------------
