      High Tg PCB The Glass Transition Temperature (Tg) is one of the most important properties of any epoxy and is the temperature region where the polymer transitions from hard, glassy material to a soft, rubbery material. When the working temperature reaches the melting point, that means the temperature exceeds the Tg value, the status of PCB material will be changed from glassy to liquid, which will affect the function of PCB. And this value is related to the stability of the PCB dimension...

      About Blind Buried Via PCB Blind vias and buried vias are two ways to establish connections between layers of printed circuit board. The blind vias of the printed circuit board are copper-plated vias that can be connected to the outer layer through most of the inner layer. The burrow connects two or more inner layers but does not penetrate the outer layer. Use microblind vias to increase line distribution density, improve radio frequency and electromagnetic interference, heat conduction, appl...

      Why Control Impedance On PCBs? When a signal requires a specific impedance to function properly, a controlled impedance should be preferred. In high-frequency applications, a complete electronic board with constant impedance is essential to protect transmitted data from corruption and maintain signal clarity. The longer the trajectory or the higher the frequency, the more adaptation is required. Any lack of rigor at this stage can increase the switching time of electronic devices or circ...

      About High Tg PCB The general TG is more than 130°, the high Tg is more than 170°, and the medium TG is more than 150°. Generally, PCB with TG ≥ 170 ℃ is called high Tg PCB. When the Tg of the substrate is increased, the heat resistance, moisture resistance, chemical resistance, stability resistance and other characteristics of the circuit board will be improved. The higher the TG value, the better the temperature resistance of the sheet, especially in the lead-free process, the application o...
