Advances in Polyamide 4T for Lead Free Solder Surface Mount Technology (SMT) Applications
Surface Mount Technology (SMT) is a high-productivity and cost-effective circuit board assembly method used extensively in the consumer electronics industry. Regulations requiring lead-free solder have pushed the peak processing temperatures of SMT to as high as 270°C. This has resulted in the need for higher temperature performance from contact and circuit insulation. Considering the rise in infotainment content on vehicles, many onboard devices already employ the lead-free SMT process. The use of lead-free SMT processes now extends to the data and control circuit devices of safety, powertrain and other vehicle electronics. Polyamide 4T is a proven performer in lead-free solder SMT applications, namely connectors in the consumer and industrial electronics industries. The use of polyamide 4T naturally translates to traditional and emerging automotive electronics applications.
