TG180 PCB Suppliers for High-Temperature PCB Materials

The numbers indicate the glass transition temperature in Celsius — the point at which the laminate shifts from rigid to soft. TG150 suits moderately elevated temperatures, TG170 offers additional thermal headroom for industrial and telecom use, and TG180 is the highest standard grade, recommended for lead-free soldering, aerospace, military, and high-power circuits demanding the greatest thermal endurance.

Yes. TG180 PCBs are specifically designed to withstand the higher reflow temperatures (typically 260°C peak) required in lead-free soldering processes. Their elevated glass transition temperature ensures the board does not delaminate or warp during RoHS-compliant assembly, making them the preferred substrate for modern halogen-free, lead-free electronics manufacturing.

TG180 PCBs are essential in aerospace and military electronics, industrial control systems and instruments, medical devices, automotive electronics including EV modules, telecommunications infrastructure, LED lighting systems, and embedded substrates. Any application involving high operating temperatures, dense component populations, or lead-free assembly processes benefits from TG180 material.

TG180 laminates exhibit significantly lower moisture absorption than standard FR4 materials. Reduced moisture uptake improves long-term electrical insulation resistance, prevents delamination in humid environments, and enhances dimensional stability — making TG180 boards particularly suitable for outdoor, marine, medical, and industrial enclosures exposed to moisture or condensation.

Absolutely. TG180 substrates are available in multilayer configurations, supporting complex high-density designs with controlled impedance, blind and buried vias, and fine line widths. SFX PCB manufactures TG180 multilayer boards with up to 68 layers, supporting applications from 4-layer industrial control boards to complex aerospace-grade multilayer assemblies.

SFX PCB holds ISO9001 quality management, ISO14001 environmental management, and ISO13485 medical device manufacturing certifications. Products are RoHS and REACH compliant, manufactured to IPC-A-610 Class 2 and Class 3 standards, and UL listed. Every bare board undergoes 100% electrical testing before shipment to ensure full compliance and reliability.
