In the field of printed circuit boards, the Tg is one of the main factors that affect their thermal and mechanical performance. With increased requirements for electronic devices to serve under various and complicated conditions, the understanding of middle Tg versus high Tg PCBs becomes very necessary. Two varieties of PCBs are covered in this article: their characterizations, applications, and selection for suitable Tg to optimize performance in electronic devices.The glass transition temperature describes the temperature at which the base material of a printed circuit board changes from a rigid and glassy state to one more flexible and rubber-like. This property is essential since it determines both operational reliability and structural integrity of the PCB assemblies, when exposed to thermal stress. PCBs that exceed their Tg will not melt, but their structures change and make the performances particularly worse, in cases where intense thermal cycling and high operating temperatures are involved. To be able to manage such mechanical stresses and avoid formation of micro-cracks in processes such as soldering, which is so crucial, choosing an appropriate Tg of a PCB becomes pretty important. This becomes particularly important with the introduction of the RoHS directive, which requires lead-free assembly and thus higher temperature demands during manufacturing.<img src="https://img.pcbx.com/dev/file/image/article/20241211/1c7d73f9f6164143b3cc693214e1bf04.jpg" alt="PCB Middle Tg vs. High Tg-PCBX" data-href="" style="width: 100%;"/><h2>Middle Tg vs. High Tg PCBs</h2><h3>Middle Tg PCBs</h3>Middle Tg PCBs have Tg values typically within the range of 130°C to 150°C.

In the dynamic semiconductor industry, product reliability and performance are not open to compromise. The demand for perfect electronics has increased the need for thorough testing methodologies. One key player in this testing domain is the burn-in board-a highly specialized tool that plays a very critical role in ensuring the dependability of semiconductor devices. This article looks closely at the detailed aspects of burn-in boards, their application in testing, and the subtleties of their design with a focus on their importance in the semiconductor manufacturing process.Burn-in boards are specially designed printed circuit boards that help facilitate the burn-in testing process, which is a method of evaluation that gives the semiconductor devices artificial aging. In this process, the device will be subjected to high temperature and electrical stress, simulating conditions like real-world operating conditions. These kinds of rigorous tests are necessary for uncovering early-life failures and ensuring long-term reliability of the devices before they reach mass production.<img src="https://img.pcbx.com/dev/file/image/article/20241206/fdb2de9045bc408c86511c63032e7270.jpg" alt="Burn-In Boards-PCBX" data-href="" style="width: 100%;"/><h3>The Burn-In Process</h3>In a typical burn-in process, semiconductor devices, normally referred to as devices under test, are securely mounted onto the burn-in board via precision-engineered sockets. These assemblies are then inserted into burn-in ovens, where they face high temperatures-usually around 125 degrees Celsius-and receive electrical signals and power. The objective is mainly to uncover hidden defects by accelerating the aging process, and there are generally three major types of burn-in tests:Static Burn-In: High currents or voltages are applied to the DUTs without operating them. This will help in finding out potential faults due to stress without engaging functional circuits. Dynamic Burn-In: Devices are operational under high temperature and voltage conditions, closely simulating actual use conditions to find performance-related issues early.Test During Burn-in: This approach involves observation of the devices under application of the test vectors to guarantee their functionality and tolerance for inputs during continuous operation.From these varied conditions, the burn-in process acts like a filtering mechanism in ensuring that only reliable devices proceed further in the chain of manufacture.<h3>Design and Material Considerations</h3>Burn-in boards are designed to operate in harsh conditions.
