What is a High TG PCB?
A High TG PCB refers to a PCB with a high glass transition temperature meaning it can withstand higher operating temperatures above 170°C (312°F) (The PCB with an important property of the material-at the higher temperature the substrate material (polymer) transits from a hard and glassy state to a soft and rubbery state). As an experienced high TG PCB manufacturer, we understand how critical these properties are for specialized industries.
What are the main features of High TG PCBs?
As the name indicates, the board is designed to stand up to high temperatures ranging from 170 °C to 260 °C. High TG PCB was introduced because today’s world demands high-performance electronic devices. If your requirement involves high power density designs whose heat generation is likely to overwhelm your heat sinks or other heat management methods, an RoHS Compliant, High TG PCB is the best fit. It protects devices from disastrous high temperatures, damaging dielectrics and conductors, and mechanical stresses caused by differences in thermal expansion rates. Leading high temperature PCB manufacturers focus on these properties to ensure reliability in harsh environments.
What materials are used to build High TG PCBs?
Some of the important known materials that can be used for High TG PCB manufacturing are FR-4 (High TG), Isola 370HR, Ventec VT-47, IT180, Panasonic R1755V/R1650V etc. The High TG PCB materials are highly reliable, having Exceptional Mechanical Properties, Excellent Chemical Resistance, Good Moisture Endurance and are Flexible in several important applications. A dependable high TG PCB manufacturer in USA will always use certified high-grade materials for superior product performance.
What are the technical aspects and characteristics of High TG PCBs?
There are certain characteristics of High TG Materials and composition of High TG PCB that make it different from the conventional PCBs.
The thermal and mechanical properties of High TG resins enhance resistance to heat, improve mechanical performance at elevated temperatures, and keep the materials stiff and glassy under heat. This results in greater stability and a reduced risk of warping, expanding, or deforming. By choosing a trusted wholesale high TG PCB company, you ensure your projects are supported by the most stable and durable materials.
What are the advantages of using High TG PCBs?
The exceptional characteristics of High TG materials advantages the device working at its normal due to:-
Dimensional Stability:
The PCB substrate maintains their dimensions at higher temperatures. This benefits the boards containing dense, complex and finely spaced circuitry.
-
Enhanced Thermal Stability:
PCBs are sometimes subject to generate repeated thermal cycles which may result in the expansion and contraction of the board material. Because the High TG materials are designed to withstand repeated heat cycles without cumulative damage makes them well-suited to the environments where temperature fluctuates, also the thermal expansion coefficient of High TG PCB is low that will contribute to reduce the risk of mechanical failure, delamination, cracking or wrapping.
Many high-TG resins possess low Z-axis CTE values. This helps resist expansion and contraction of boards alongside the direction of thickness as temperature varies.
Basically, the High TG PCB materials offer enhanced performance and longevity in demanding thermal conditions compared to standard FR-4 glass epoxy substrates.
The high TG resin allows plated through holes (PTHs) to retain their integrity at higher operating temperatures and heat cycles. This plays a crucial role for the boards with small and high-density PTHs.
We have benefits of choosing the High TG PCB materials like reliability in High temperature environments, Heat Dissipation management in Dense and complex PCBs, Dimensional Stability for Lead Free Soldering. The LF HASL melts at higher temperatures than the regular HASL. High TG materials retain their rigid properties at these elevated temperatures that are much needed for Lead Free soldering.
Choosing a reputable high temperature PCB manufacturer ensures your designs are future-proof and performance-driven.
What are the different applications of High TG PCB?
Automotive Electronics
High TG PCBs play an important role in automobile applications like ECU (engine control unit), ADAS (advanced driver assistance system), onboard computers, various sensors, dashboards and other electronic systems because their capabilities to tolerate high temperatures and survive in a harsh environment.
Oil and Gas Industry
The electronics used in downhole drilling in Oil and Gas Industry must have the ability to with stand high temperatures and pressure in extreme conditions. High TG PCBs have proven their excellence in applications like pressure control systems, offshore safety control systems, motor controllers and oil and gas measurement systems.
Aerospace and Defense
For aerospace and military applications, there is always a potential of having extreme temperature fluctuations with vibrations due to high altitudes. To withstand and survive these harsh conditions, the electronics used must have the ability to function as it designed. High TG PCB will help to attain this goal without compromising the performance of the devices in satellite, several military equipment etc.
Industrial Electronics
High TG PCBs are used in Power electronics applications such as motor drivers, power supplies and inverters as these may produce a considerable amount of heat during operation. All the control systems used for industrial automation and robotics systems also rely on high TG PCB to give out convenient operation in high temperatures without fail.
Medical Applications
High TG PCBs are employed in devices like blood analyzers and other diagnostic tools for stable performance and reliability. High TG PCBs are also used in X-ray machines and MRI scanners because of the need for consistent operation under high-power settings.
Electronics Test Equipment
Devices like oscilloscopes and signal analyzers use High TG PCBs to get accuracy and performance stability under extreme thermal conditions.
Consumer Electronics
High TG PCBs are also proven well in high performance computing devices, high-end laptops and desktops which will generate heat during the operation. Some of the advanced wearables also benefit from high TG PCB because of their high-temperature operations and environments.
Partnering with an experienced wholesale high TG PCB company ensures you can access these advanced capabilities across multiple industries.
