The book is important because it reflects a trend, especially in microelectronics manufacture toward recyclability. Europe and Asia are moving towards legislation to ban the use of lead in solders and public demand in the US will likely have the same result. Producers of solders and manufacturers who use them will have to invent and employ suitable substitutes and A Guide to Lead-free Solders will show them how to do so.The homologous temperature, Th, maybe defined as the ratio of the use temperature, T, to the melting temperature, Tm, h m T T T (1.2) where the temperatures are expressed on the absolute scale in Kelvin (McClintock and Argon 1966).
