High Temperature PCB
When fabricating PCBs for high temperature applications, the glass transition temperature of PCB is extremely important to consider. If the temperature in the application exceeds the “Tg” value, it leads to issues related to the board’s performance. Not only can the rise in temperature lead to the material expanding, with different materials having different thermal expansion coefficients, there will also be mechanical stress leading to micro cracks. While some of these could be detected during electrical testing, some may go unnoticed, leading to failure of the product and costing you, well-earned reputation.
At Technotronix, we specialize in High Tg PCBs (high temperature printed circuit boards) that offer heat resistance. Made of FR-4 substrate material, they are widely used across industries as they provide better heat resistance, as well as mechanical and chemical stability for the board.
