DVD-45C 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.
