Hi Sue Is your process a hand insertion? If yes, then you will have to prep your components to the correct lead protrusion prior insertion to eliminate trimming after wave. You will required prepping tool / equipment. I have a contact information, I can provide a name offline if you are interested. Good luck Luis Gallegos Process Engineer Sanmina-SCI [log in to unmask] Phone: 262 947-7700 Direct: 262 947-2765 Fax: 262 947-7728 -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of Suzanne Runals Sent: Friday, August 04, 2006 2:26 PM To: [log in to unmask] Subject: [TN] Lead Cutting/Fractured Solder Joints We are experiencing fractured solder joints in our manufacturing process. We know it is caused from the lead trimming we are doing. We do not have automated equipment that will cut and clinch the leads. I wanted to reflow the boards a second time until we get our process under control but not everyone agrees with that. They are afraid of damage to the components caused by the heat of the reflow. Has anyone else experienced this issue before and what did you temporarily do to alleviate the problem while working on the real issue of the lead cutting process. I have tried visual inspection but these boards are dense boards and we missed some joints and they were returned to us again by our Customer. IPC 610 section 7.5.5.8 states you may reflow and it is not considered rework. However they mention nothing about reliability if we do this.
