Johannes, Finding the minimum distance that will prevent solder shorts will depend largely on your process since bridges are related to surface tension. You might be better served to look at masking alternatives, both perminant and temperary inclucing fixturing. If they must be soldered look at using thieving pads. Good luck, MB ############################################################## 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.
