Are there any standards for testing the solder joint mechanical strength for surface mount gull wing lead? We are wondering if there are any standards and test methods for the force required to break the solder joint of individual fine pitch leads when it appears to be a poor joint from visual inspection. We would like to confirm a poor joint through some simple non-destructive test in our receiving inspection area when receiving assembled PCB's from our board assembly supplier. In other words, this is finished product. Our idea was to use a force gauge pushing on the side of the lead and measuring force to break the joint. But we don't know what is acceptable without a lot of testing. So, would this be a valid test of a solder joint, are there established methods for a test like this, and are there acceptable ranges of force for different types of SMT packages? ################################################################ TechNet E-Mail Forum 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's web site (http://www.ipc.org) "On-Line Services" section for additional information.
