FR4 Material

PCB manufacturing involves using various base materials, with copper-clad boards—often FR4 with copper layers on both sides—being the most common. FR4 is considered the most cost-effective and reliable material for multilayer PCBs. However, some small manufacturers use low-quality FR4 to reduce costs, especially for prototypes. While using cheaper materials may seem viable, it can compromise quality control. Larger PCB manufacturers, such as Shenzhen SysPCB, use high-quality FR4 materials from suppliers like Kingboard, Shengyi, and Isola to ensure consistent quality, particularly in mass production. High-volume production can reduce costs without compromising material quality, often making high-quality FR4 just as affordable as low-quality alternatives. Read More

High Tg PCBs have a glass transition temperature above 170°C, offering better heat, mechanical, and chemical resistance. They are ideal for lead-free processes, multilayer, and high-density interconnect (HDI) boards, effectively managing the heat from high power density. High Tg PCBs are widely used in computers, communication equipment, and precision instruments that require high heat resistance, meeting RoHS requirements. Shenzhen PCB manufacturer SysPCB offers various high Tg PCB products, supporting multilayer boards, multiple surface treatments, and solder mask colors. Read More
