What Is High Temperature PCB?
High Temperature PCB generally refers to a printed circuit board made with material that offers stronger temperature performance than standard PCB material. This page explains what High Temperature PCB usually means, what High Tg material refers to, why customers may need it, and how to choose it in the online quote process.
Basic Meaning of High Temperature PCB
In practical PCB use, High Temperature PCB usually means a PCB that uses material designed for stronger temperature performance than standard PCB material.
Customers may choose this type of material when the project environment, thermal conditions, or product requirement calls for better heat resistance or stronger material stability.
What Does High Tg Mean?
Tg stands for Glass Transition Temperature. In practical PCB material selection, a higher Tg value usually indicates that the material is intended for stronger temperature performance than a standard material.
In the online quote system, you may see high temperature material options such as:
- High Temperature FR4 -- Tg 160°C (320°F)
- High Temperature FR4 -- Tg 170°C (338°F)
- High Temperature FR4 -- Tg 180°C (356°F)
Why Do Customers Choose High Temperature PCB?
Not every PCB order needs high temperature material. However, some customers select it because their design or product environment requires stronger temperature performance than standard PCB material.
- Higher operating temperature requirements
- Projects with stronger thermal stress
- Product specifications requiring higher Tg material
- Designs that call for better material stability under heat
If your project documentation or engineering requirement specifies high temperature material, you should select the appropriate PCB material during the quote process.
Standard PCB Material vs. High Temperature PCB Material
Standard PCB material is suitable for many ordinary PCB applications. High temperature PCB material is generally selected when the project needs stronger temperature performance.
| Material Type | General Use |
|---|---|
| Standard PCB Material | Common PCB applications with normal temperature requirements |
| High Temperature PCB Material | Projects requiring stronger temperature performance or higher Tg material |
When Should You Choose High Temperature PCB Material?
You should consider high temperature PCB material when your design, specification, or customer requirement calls for stronger temperature performance than standard PCB material.
- Your engineering drawing specifies high Tg material
- Your project has elevated operating temperature conditions
- Your customer requires high temperature FR4
- Your application needs stronger thermal reliability
If you are unsure whether standard material is sufficient, it is best to confirm the requirement with your engineer or product specification before placing the quote.

High Temperature PCB FAQ
Is High Temperature PCB required for every PCB order?
No. Not every PCB order needs high temperature material. It depends on the project requirement, operating condition, and engineering specification.
What does High Tg mean?
High Tg means a higher Glass Transition Temperature in the PCB material. In practical use, it usually refers to material selected for stronger temperature performance.
Where do I select High Temperature PCB material?
You can select it in the PCB Material dropdown menu after choosing the required PCB layers in the online quote page.
