FLEXcon announces the launch of THERMLfilm® HT™, a new advanced line of high-temperature polyimide films able to withstand the fluctuating temperatures, abrasion and chemicals inherent in the printed circuit board (PCB) manufacturing process. The new product line will be available worldwide to manufacturers that need high-density barcode and alphanumeric PCB labels, including military contractors and manufacturers of electronics, aerospace and automotive goods. The PCB manufacturing process is one of the harshest environments to which pressure-sensitive films can be subjected. FLEXcon has put extensive development effort into the THERMLfilm® HT™ line. The result is products that meet industry standards and pass all requirements for this challenging environment. All THERMLfilm® HT™ products are tested to ensure PCB labels will remain adhered and legible throughout the manufacturing process. FLEXcon’s specially formulated topcoat provides a super smooth printing surface. The product is an ideal substrate for high density information such as data matrix codes, and provides consistent ANSI scannability. In addition, the static dissipating qualities of the topcoat minimize the risk of print voids to ensure optimum print quality and consistency.
THERMLfilm® HT™ line can endure the standard PCB process as measured by MIL-STD-202G, Notice 12 and MIL-STD-883E, Notice 4. L.a.b barcode scannability testing reveals consistent ANSI scannability after exposure to high heat. Heat resistance testing has revealed endurance at 500°F/260°C continuously for 5 minutes and intermittently at up to 750°F/398°C. In addition, in-line durability testing is performed using VIGON®* A 201 chemical cleaner. This testing combination ensures THERMLfilm® HT™ products will withstand the harsh environment of the in-line reflow and cleaning processes, yielding consistent and maximum performance.
