What Is a High Tg PCB?
A High Tg PCB uses material that withstands much higher temperatures than standard FR4. Tg stands for Glass Transition Temperature. It marks the point where a material changes from solid and glassy to soft and rubbery. Standard FR4 PCBs have a Tg around 130â140°C. High Tg PCBs have a Tg higher than 170°C, offering better thermal stability and mechanical strength.
When the boardâs temperature goes above its Tg, it may deform and lose performance. But a high Tg PCB stays stable. Thatâs why these boards are ideal for automotive electronics, LED lighting, industrial control, and high-power devices. They help your products last longer and work better under thermal stress.
In fact, many customers in the LED sector prefer high Tg FR4 over metal core PCBs for cost reasons, especially when the thermal conductivity demands are moderate.
In short:
- Normal FR4 Tg: 130â140°C
- High Tg FR4: â„170°C
- Suitable for: high-power, high-heat, multi-layer PCBs
FR4 Tg 170 Datasheet
At Best Technology, we commonly use SYL’s S1170 material for high-TG PCBs. Hereâs a simple view of the FR4 Tg 170 datasheet you can refer to:
| Item | Specification |
|---|---|
| Tg (DSC) | â„170°C |
| Decomposition Temp (Td) | >340°C |
| Thermal Conductivity | 0.35 W/m·K |
| Flammability Rating | UL 94 V-0 |
| CTI | â„300V |
| Water Absorption | <0.10% |
| Electrical Strength | â„40 kV/mm |
This material shows excellent stability at high temperatures and good insulation properties. Itâs highly recommended for multi-layer PCBs, fine-pitch SMT, and lead-free soldering processes.
Special notes:
- SYL S1170 is also widely used in high-brightness LED projects.
- It supports PCB structures with over 6 layers.

Who Manufactures High Temp PCB?
Many suppliers claim they can build high temp PCBs, but not everyone offers real high-TG expertise. Hereâs a quick introduction to three trusted manufacturers:
Best Technology Co., Ltd (China)
- Specializes in high Tg PCB, ceramic PCB, metal core PCB, and flex PCB. We support low to high volume PCB fabrication with no MOQ. Focused on quick turn, high quality, and customized solutions.
Isola Group (USA)
- A famous material supplier, Isola also partners with certified PCB manufacturers worldwide. Their FR406 and IS410 laminates are industry benchmarks for high-TG applications.
Shengyi Technology (SYL) (China)
- SYL is one of the largest laminate suppliers globally. Their S1000-2 and S1170 series offer consistent high TG performance for automotive, telecom, and industrial markets.
When choosing a high-temp PCB supplier, always check the raw materials, production capability, and real project experience. Best Technology stands out with full in-house capabilities and quick support, which customers love.
Who Is the Largest High Tg PCB Manufacturer in the World?
Globally, several players dominate the high-TG PCB space. Here are three of them:
TTM Technologies (USA)
- A global leader, offering everything from standard boards to complex high-temp, high-density interconnects. Serves aerospace, defense, and medical markets.
AT&S (Austria)
- A premium PCB manufacturer known for automotive and industrial PCBs, especially where high reliability and temperature resistance are key.
Unimicron (Taiwan)
- One of the largest PCB manufacturers by volume, focusing on consumer electronics, automotive, and communication markets with advanced high-TG solutions.
If you need high reliability, stable supply, and top-notch quality for high volume projects, looking at giants like TTM or AT&S helps. But if you want more flexible service with great pricing and fast action, Best Technology is your best partner in China!
China High Tg PCB Manufacture
China plays a critical role in global PCB production. Letâs quickly review three top Chinese high-TG PCB manufacturers:
Best Technology Co., Ltd
- Known for specializing in high-mix, low-to-medium volume PCB production. Offers a full range of high TG PCBs, ceramic PCBs, and flex circuits. No MOQ. High repeat orders from Europe, USA, and Asia.
Suntak Technology
- One of China’s largest PCB manufacturers. They focus on volume production for consumer and automotive industries. Some lead times are longer for customized projects.
Victory Giant Technology
- Strong in industrial, automotive, and IoT sectors. Offers mass production of high-TG boards and HDI boards.
For cost-effective, fast delivery, and personal service, a manufacturer like Best Technology offers huge advantages over mass-market factories.
How to Choose a High-TG PCB Manufacturer for High Volume PCB Manufacturing?
Choosing the right High-TG PCB manufacturer for high-volume production is crucial. Here are a few tips:
Evaluate their raw materials
- Ask what laminate brands they use. Good suppliers work with SYL, Isola, or Panasonic.
Check production capability
- Can they handle large panel sizes, tight tolerance, and multiple solder mask colors?
Look for experience
- Have they produced PCBs for similar industries before? Ask for case studies or references.
Speed and flexibility
- Even for large orders, can they offer fast lead times and respond quickly to changes?
Certifications
- Look for ISO 9001, ISO 14001, UL, IATF 16949 (for automotive projects).
Support for Prototypes
- Starting with small batches before mass production reduces risks.
In short, not every PCB maker who claims “high-TG” really understands your needs. Itâs better to partner with someone proven.
