Circuit Board High-Temperature Buffer Pads are essential auxiliary materials in the manufacturing process of printed circuit boards (PCBs), playing a crucial role in the lamination process of multilayer boards. As a professional manufacturer of lamination buffer pads, we fully understand the importance of this special material in ensuring the quality of PCBs under high-temperature and high-pressure conditions.
The requirements for PCBs in modern electronic devices are constantly increasing, especially in fields such as 5G communication, artificial intelligence, and automotive electronics. These application scenarios have raised higher standards for the reliability and stability of circuit boards. High-temperature buffer pads have become key components in PCB manufacturing under such circumstances, with their main functions including:
High Temperature Protection: Maintain performance stability at pressing temperatures of 180-220℃
Pressure Buffering: Evenly distribute the high pressure of 200-400psi applied by the press
Surface Protection: Prevent damage to the copper foil and substrate of the circuit board during lamination
Dimensional Stability: Ensure precise alignment between layers of multilayer boards
Thermal Conduction Equilibrium: Promoting even heat distribution during the lamination process
