Most high reliability electronic equipment producers continue to manufacture and support tin-lead (SnPb) electronic products despite the increasing trend for design and conversion to Pb-free manufacturing. These equipment suppliers can continue to use SnPb solder assembly and remain in compliance with the RoHS Directive (restriction on certain hazardous substances) by invoking the European Union Pb-in-solder exemption. At the same time, companies are facing increased pressure from a component supply chain that is rapidly converting to Pb-free offerings and thus has a decreasing motivation to continue producing SnPb product for these low-volume end users.
