To anyone who can help.... Is there a "standard" in the industry regarding which machine parameter for tape and reel equipments should be held constant and which may be varied within a range? The parameters we monitor on our end are as follows: 1. Sealing temperature for Front and Rear sealing blades. 2. Sealing pressure for Front and Rear sealing blades. Is there anything we are not covering but ought to? I need any input so I can evaluate the SPC program we have at the moment.. We are using Microvision and STI equipments. Any thoughts on the matter will be highly appreciated. Should you require addtl. info., go on and ask.... marc ############################################################## TechNet Mail List provided as a free service by IPC using LISTSERV 1.8c ############################################################## To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TECHNET <your full name> To unsubscribe: SIGNOFF TECHNET ############################################################## Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information.
