DVD-45 L/F


This training program is intended for operators who already understand the basics of hand soldering, and simply need to learn the differences between soldering with tin-lead vs. lead free solder. For a more detailed lead free hand soldering video that also covers basic soldering theory, please see DVD-43.Now you can show your operators the subtle differences between tin-lead and lead-free soldering techniques & inspection criteria – with this new training DVD from IPC. This program is designed to assist operators and soldering technicians to make the transition to lead-free with knowledge and confidence.DVD-45 describes these new types of solder alloys, and discusses the higher melting temperatures that can potentially damage the assembly. Section 1 also explains required changes due to increased surface tension, more active fluxes, and additional cleaning considerations.Section 2 demonstrates modified techniques for soldering through-hole components into plated-through holes, and wires to pierced terminals, then demonstrates PTH rework / vacuum extraction – focusing on damage prevention from increased soldering temperatures.Section 3 compares tin-lead / lead-free solder joints to the visual acceptance criteria from IPC-A-610D – with original microphotography of target conditions, textural differences, minimum and maximum solder, wetting requirements, cold / disturbed joints, fractures, lifted lands, thermal damage, bridging, projections, blowholes and solder balls. Time: 23 minutes.
