In the field of electronic manufacturing, as electronic products are developing towards miniaturization and high performance, the requirements for temperature control accuracy in the production process are becoming more and more stringent. Dry-block calibrators, with their excellent temperature stability and accuracy, have become an ideal choice for high-precision temperature testing in electronic manufacturing. For example, in the semiconductor chip manufacturing process, key process steps such as photolithography, etching, and diffusion all require an accurate temperature environment to ensure the performance and yield of chips. Dry-block calibrators can provide an environment with extremely small temperature fluctuations and accurately calibrate the sensors used to monitor the temperature of these processes, keeping the temperature error in the chip manufacturing process within a very small range. In addition, in the burn-in test of electronic components, dry-block calibrators can simulate different high-temperature environments, helping to detect the reliability of electronic components under long-term high-temperature operation and ensuring the stability and durability of the final product in actual use.
