Hello davef - could it be you are confusing low thermal emf (Seebeck coefficient) with low temperature solder ? I am looking after solder wire and paste with low Seebeck coefficient - cadmium based alloy was OK but banned in europe due to RoHs direct

IPC-8921 establishes classifications and designations for woven and knitted e-textiles integrated with e-fibers, e-yarns and e-wires. It also standardizes key characteristics and durability testing for these materials as well as the industry test methods to be used to test against those characteristics.

As the role of direct-chip-attachment increases in the electronics industry, the reliability and performance of COB packaging materials becomes an increasing concern. Although many factors influence component reliability, the biggest determinants of performance are often the glass transition temperature (Tg) and the coefficient of thermal expansion (CTE) of the encapsulant or underfill. This paper discusses exactly what these properties are, how they are measured, and why they are important to device-reliability.

Engineers are always striving to make a lighter, faster and stronger PCB. In order to achieve their designs, engineers must turn to alternative materials to enhance their designs. There are many materials that allow for thermal, coefficient of thermal expansion (CTE) and rigidity. Many times if a material enables an engineer to have CTE they will have to sacrifice thermal. Currently carbon composite laminates are being used in order to achieve an ideal PCB with thermal, CTE and rigidity with almost no weight premiums.

. The CTE (Coefficient Thermal Expansion) relates to the PCB expansion in the "X" axis or board length and width. Or the linear dimensional change of material per unit change in temperature.
