Hi Technos, we are advancing in exploring new technologies. Some time ago I tapped your wisdom for info on flex circuits, now I have a better one. What is "laser trimming of resistors"? According to the small research I did, it's related to thick films. Is that true? What should I read on this, starting with some on-line resources? Keeping in mind that we are assemblers, not board manufacturers, how is this trimming related to SMT assembly, what equipment would do it (at what cost), implementation issues, etc. Best regards, Ioan --------------------------------------------------------------------------------- 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 ---------------------------------------------------------------------------------
