Here's an easy one. Page 5-12 of IPC-A-610C shows radial PTH components with a standoff between the component base and the board. 1) How do you all meet this requirement? 2) What is the purpose of it? 3) How do you inspection for it? My guesses: 1) lead forming, soluble plastic disks or tubing, friction fit, by chance, don't 2) heat dissipation, inspection, strain on solder joint 3) eye, thickness gauge, don't I await your sage comments, oh wise ones. regards, Bev Christian XLTEK ############################################################## 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.
