Printed circuit boards (PCBs) are an indispensable component in electronic devices worldwide, making them an integral part of the electronics enthusiast’s realm. Consequently, terms like “TG170,” “FR4 TG170,” or “TG170 PCB” have become commonplace, particularly within the electronics industry. During the PCB manufacturing process, the boards often undergo exposure to high temperatures, particularly during lamination.
Therefore, it is crucial to ensure that the PCB material chosen for constructing the circuit board possesses the ability to withstand these elevated temperatures. This not only guarantees a successful and efficient PCB manufacturing process but also ensures optimal performance and reliability during subsequent usage. This article aims to provide a comprehensive exploration of the TG170 PCB material and its inherent value as a crucial component for meeting your circuit board requirements.
Definition of TG
In PCB prototyping, we often utilize FR4 TG150 and TG170 laminates alongside the commonly used FR4 TG130 in previous PCB samples. Understanding the advantages of these two laminates compared to FR4 TG130 is crucial. To address this, let’s first clarify the concept of TG.
TG, or glass transition temperature, refers to the temperature at which a material transitions from a rigid state to a softened or rubbery state under high-temperature heating. In the case of circuit boards, it is essential for them to be flame-resistant and capable of withstanding specific temperatures without burning, instead only softening. This temperature is known as the glass transition temperature (Tg), which directly affects the dimensional stability of the PCB.
A higher TG value signifies better temperature resistance for the board. This holds particular importance in applications such as lead-free tin spraying processes, where higher Tg values are commonly employed.
Generally, TG values for PCB sheets are above 130 degrees Celsius, with high-TG laminates typically exceeding 170 degrees Celsius, and medium-TG laminates around 150 degrees Celsius. High-TG laminates find extensive use in multilayer printed circuit boards, especially those employed in automotive, packaging, embedded substrates, precision industrial control instruments, routers, and other fields.
As the Tg value of a board increases, its heat resistance, moisture resistance, chemical resistance, and overall stability are improved accordingly. Consequently, TG170 and TG150 laminates outperform TG130 in all aspects, providing enhanced performance for various applications.
To meet the diverse PCB requirements of our customers and deliver superior PCB services, JarnisTech has incorporated TG150 and TG170 laminates into our offerings. This expansion allows us to cater to a broader range of market demands and ensure we can provide the most suitable PCB solutions for our valued clients.
What Is TG170 PCB Circuit Board?
TG170 is a high glass transition temperature (Tg) FR4 material commonly used in printed circuit board (PCB) manufacturing. The Tg refers to the temperature at which the epoxy resin transitions from a tough, glassy state to a soft, rubbery state. A higher Tg indicates the material can withstand higher temperatures before softening.
Flame resistance is an important property of PCB laminates. Each epoxy material softens at a different temperature range. The point at which softening occurs is the Tg or glass transition temperature.
With a Tg of 170°C, TG170 FR4 can withstand temperatures up to 170°C during lamination without compromise. Since TG170 has a high Tg, higher lamination temperatures are required. Maintaining a rigid, crisp laminate is crucial for proper hole dimensions and electrical performance. Exceeding the Tg can cause the material to soften, melt, or deform, degrading the PCB’s electrical and mechanical integrity.
Standard FR4 typically has a Tg of 130-140°C. Moderate Tg resins can handle 150-160°C. High Tg materials like TG170 can withstand 170°C or more. The higher the Tg, the better the moisture, thermal, chemical and dimensional stability of the finished board.
If temperatures approach the melting point during operation, the material transitions from solid to liquid, leading to PCB failure. Tg strongly influences stability and dimensional accuracy.
TG170 is a popular high Tg material for communication equipment, computers, instrumentation and other precision devices where thermal/mechanical reliability is critical. Its robust performance makes it well-suited for demanding applications.
