We are using the following formula to set up Upper and Lower Specs for the solder paste height: Solder paste Stencil thickness +2 mils/-1mil. Unfortunately, we do not have capability to measure solder paste volume. ------------- Original Text From: C=US/A=INTERNET/DDA=ID/TechNet(a)IPC.ORG, on 12/18/97 7:16 AM: REGARDING OH MY GOD !!!!!!! NOoooooooo......... I thought that might have got your attention ...... Now my question, What are people using for Upper and Lower Specification limits on control charts for Paste height and volume, Fine pitch and standard.? I remember somebody else had asked this question some time ago, but unfortunately I've deleted the email already...... Happy Christmas, John O'Sullivan. ############################################################## 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.
