I suspect your heat sink pins that are soldered as through hole components are rectangular in shape. If they are why not make the holes they go in smaller so that a little pressure is needed to insert the Heat shield. Square peg in round hole principle. Sounds like an engineer, they say under their breath.

This shield is being hand placed onto the board before reflow where perimeter is getting connected to the board while the leads are soldered when the board goes to wave soldering process. Our problem is that this part is getting tilted easily and to prevent that I am looking for some kind of solution- Does anyone has tried out the kinked leads to provide snap fit so that it won't tilt during the reflow operation. Any other potential solution to stop the tilt besides some kind of weight. Does anyone ordered die and formed the leads and resolved the tilt problem? My part is 1.5" X 2.5" with .5" height. Leads are .5" apart. re, ken patel ______________________________________________________ Ken Patel Phone: (408) 490-6804 1708 McCarthy Blvd. Fax: (408) 490-6859 Milpitas, CA 95035 Beeper: (888) 769-1808 ############################################################## 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.
