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.
Capabilities in High Temperature PCBs
We offer high Tg printed circuit boards that offer flawless performance in high temperature applications. With over 4 decades of experience in the industry, we are armed with the following capabilities:
- Our PCBs are made of flame-retardant epoxy material that stands the test of high temperature.
- Our printed circuit boards have mechanical strength and dimensional stability.
We offer a wide range of surface treatment options such as:
- HASL /Lead Free HASL
- ENIG /Immersion Gold/Immersion Silver/Immersion Tin
- In addition, we offer multi layered boards with a minimum size of 10*15mm and a maximum size of 500*600mm
- The boards come with a wide range of solder mask options

Benefits of High Tg Printed circuit boards
- Be resistant to high temperatures
- Have low thermal expansion
- Have mechanical strength
- Have high thermal stress resistance
- Long delamination durability
- Low Z axis expansion (CTE)
- Improved stability of the device including heat and moisture resistance
- A great solution when you are dealing with a device that has a high heat generation rate.
- An ideal solution for multilayer PCBs, which have dense circuits.
