I am doing some research on HAND SOLDERING CRITERIA, for a project I am currently undertaking. I would like some fundamental information regarding the criteria for a hand soldered joint between the component lead and the contact pad on the printed circuit board. Criteria I am looking for is of the nature; - mechanical strength of soldering joint - electrical strength and properties of soldering joint - thickness of solder joint If someone can help me with this information (or more) it would help me in my current project. thanks M.C.M. ################################################################ 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.
