Ryan, We are currently using the light pipes on several assemblies. They do not fit especially tight. We do heat stake them using metal shim stock underneath the board. This is slightly easier than placing, clinching, and waving; and saves one less "thermal cycle" to the board. Regards, Michael Sanders Ryan Jennens <jennens@TELG To: [log in to unmask] EN.COM> cc: Sent by: Subject: [TN] LED light pipes TechNet <[log in to unmask] ORG> 04/28/2000 10:37 AM Please respond to "TechNet E-Mail Forum."; Please respond to Ryan Jennens Hey all- Engineering has come up with the idea of replacing some bi-level LEDs with smt LEDs and attaching light pipes. These Dialight light pipes "press-fit" into drilled holes in the board. I am not sure if we are trading one process step for another. We currently selectively wave solder the pth LEDs, but there are some resistor networks making the pallet openings a little hairy...but it is feasible as they are. My question is: how tight do these light pipes press in? Is anybody else doing this? Do I need to heat-stake these things? If so, it doesn't sound like any advantage from a manufacturing point of view. If not, is it easier to press these in than place pth parts, clinch and wave? I am not completely sold on this idea. Thanks all. -Ryan Jennens TelGen Corporation (517) 887-6666 x151 ############################################################## 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.
