Introduction to High Tg PCB
High Tg PCBs (High Temperature PCBs) are a reliable choice for high-temperature applications because they can withstand elevated temperatures without losing mechanical or electrical properties. Standard FR-4 laminates hold up to around 130-140°C. For applications that encounter higher temperatures, High Tg laminates are capable of withstanding over 170°C. In the most demanding environments, polyimide materials excel with a tolerance for temperatures exceeding 260°C. Selecting the appropriate Tg value is important to ensure your circuit board performs reliably under high-temperature conditions.
We select materials with the right Tg values for your design and application, using rigorous testing to ensure reliable PCB performance even in demanding conditions. Meanwhile, we can also provide metal-based PCBs that offer excellent heat dissipation performance, such as aluminum PCBs, LED PCBs, metal core PCBs, copper-based PCBs, and more.
High Tg PCB Manufacturing
We use inner layer, lamination, and drilling technologies to ensure the quality of our High Tg PCBs, which are made to withstand challenging high-temperature applications.
For inner layer production, we use specialized materials, including high temperature, high speed, high frequency, thick copper, and thin dielectrics, to produce high-layer count PCBs. It can be challenging to regulate signal transmission with such materials, but we address these issues effectively. As trace width reduces, risks of open or short circuits increase, potentially degrading yields. Similarly, adding more signal layers and finer traces can lead to AOI misses, especially on internal layers. Additionally, thinner inner layer dielectrics are more vulnerable to folding, leading to problems with etching quality. We combat these challenges by upgrading our equipment and using high-precision etching lines, ensuring standardized, clean etching and better quality boards.
Lamination of high-layer PCBs presents its own set of challenges, especially with thinner dielectric materials and different Tg values across multiple layers. Issues like resin cavities, bubbles, or laminate slippage can arise during the lamination process. These challenges are compounded when multiple layers are involved, making it difficult to manage expansion and contraction. We address these issues by closely monitoring the coefficients of expansion and contraction and by using software to control the lamination process. We ensure compatibility and maintain reliability even for specialized or mixed-material PCBs.
Drilling through multiple layers with high Tg, high speed, high frequency, and thick copper requires precision to prevent issues like burrs or drill bit breakage. Drilling becomes particularly challenging when there is significant copper thickness, increasing the risk of breakage. To solve this, we adjust the speed and insertion rates for each drilling point to optimize the process, and we also measure PCB expansion and contraction accurately to maintain manufacturing precision. These efforts ensure the final product is reliable, with all specifications met.
