BT substrate (Bismaleimide-Triazine) is a high-performance resin system used extensively in the production of build-up films for semiconductor packaging. This material is particularly valuable in the electronics industry due to its excellent thermal stability, low moisture absorption, and superior electrical properties. BT substrates are commonly used for high-density interconnect (HDI) PCBs, which are critical in the manufacture of advanced consumer electronics like smartphones, tablets, and other portable devices. The development of BT substrates continues to evolve with the growing demand for miniaturized and more efficient electronic components, supporting the trend toward more compact and faster-performing devices.

Due to their robust nature, BT substrates are highly favored for use in high-end applications that require reliability under extreme conditions. These substrates are integral to the manufacture of multilayer circuit boards that serve as the backbone of modern electronic equipment. The durability and high performance of BT substrates also contribute to extending the lifecycle of end devices. As the electronics market continues to innovate, the need for more sophisticated and reliable substrates like BT will increase, driving demand in the build-up film market.

ABF Substrate

ABF (Ajinomoto Build-up Film) substrate is another advanced material used in the production of build-up films, particularly in the semiconductor packaging industry. Known for its excellent properties, ABF substrates offer superior dimensional stability, low CTE (coefficient of thermal expansion), and enhanced resistance to moisture, making them ideal for high-performance electronic devices. ABF substrates are predominantly used for chip packaging, which is essential in the miniaturization of semiconductors, enabling smaller and faster electronic devices. The growing trend for high-speed computing, high-definition displays, and other advanced electronics is pushing the demand for ABF substrates, particularly in sectors like telecommunications and computing.
