FLEXcon has launched THERMLfilm HT, a 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 bar code 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. The THERMLfilm HT line meets industry standards and passes all requirements for this challenging environment. All THERMLfilm HT products are tested to ensure that PCB labels will remain adhered and legible throughout the manufacturing process. FLEXcon’s specially formulated topcoat provides a smooth printing surface. The product is appropriate 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.

“As a FLEXcon partner that tests the quality and durability of PCB labels, we must assure our customers that they can meet and surpass the most stringent cleaning requirements,” says Sal Sparacino, technical marketing manager, Zestron Corporation. “The THERMLfilm HT line creates a new industry standard in performance and can withstand the harshest elements, that can ultimately impact produce performance.”

“Printability and heat resistance are the most critical factors in choosing materials for PCB labeling,” said John Bennett, FLEXcon vice president, Product Identification Business Team. “These labels contain crucial information for the production process which, if lost, result in disruptions that impact profitability, so finding film products you can count on makes all the difference. FLEXcon prides itself on developing reliable solutions that withstand all elements.”

THERMLfilm HT can endure the standard PCB process as measured by MIL-STD-202G, Notice 12 and MIL-STD-883E, Notice 4. L.a.b bar code scannability testing reveals consistent ANSI scannability after exposure to high heat. Heat resistance testing has revealed endurance at 500°F/260°C continuously for five minutes and intermittently at up to 750°F/398°C.

According to FLEXcon, all THERMLfilm HT products are identical worldwide. These 1 and 2 mil polyimide films are held in stock on FLEXcon’s 50 lb. (80 GSM) glassine liner. Made-to-order products are also available on a 1.5 mil (37 micron) polyester liner and a 50 lb. (80 GSM) SCK liner to meet specific application and dispensing requirements. FLEXcon plans to build a comprehensive line of high-temperature films with additional product launches in the future.
