Summary:

Surface Mount Technology (SMT) is a high-productivity andcost-effective circuit board assembly method used extensively inthe consumer electronics industry. Regulations requiring lead-freesolder have pushed the peak processing temperatures of SMT to ashigh as 270°C. This has resulted in the need for higher temperatureperformance from contact and circuit insulation. Considering therise in infotainment content on vehicles, many onboard devicesalready employ the lead-free SMT process. The use of lead-free SMTprocesses now extends to the data and control circuit devices ofsafety, powertrain and other vehicle electronics.Polyamide 4T is a proven performer in lead-free solder SMTapplications, namely connectors in the consumer and industrialelectronics industries. The use of polyamide 4T naturallytranslates to traditional and emerging automotive electronicsapplications.Using polyamide 4T in lead-free SMT processes allows a designengineer to realize additional benefits of stable electricalproperties, low warp, good dimensional stability, and the abilityto design in environments with USCar Class 4 and higher continuousoperating temperatures.With higher thermal, chemical and mechanical demands beingplaced on components in the engine compartment there will be anincreasing demand for higher performance resins in electronicsapplications.Performance data will be given showing why polyamide 4T is thelow risk choice compared to other high heat resins for automotiveelectronic SMT applications
