Topic for end of day or beginning of long weekend... A question for those of you who are on the assembly end or work with assembly facilities: what kind of environment or class cleanroom is utilized for incoming inspection for high end substrates like organic MCM, fineline, cavity boards, etc. And given the specific environment, what characteristic(s) determined the need for that environment. Thank you for your input, Jana Carraway Lake Oswego, Oregon --------------------------------------------------------------------------------- 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 ---------------------------------------------------------------------------------
