Solution overview

Thermoelectric coolers (TECs) are core thermal management components in the fields of photonics and optoelectronics, with their manufacturing processes placing strict demands on vacuum soldering precision, packaging hermeticity, and non-destructive testing. For example, a global leader in optoelectronic devices faces stringent process requirements in the research, development, and application of thermoelectric coolers. their products must meet high thermal conductivity and low solder void rate (<10%) to improve the efficiency and reliability of the TECs, while also adapting to the miniaturization and high-power density trends in the industry.

The combined solution of the MUX400 high-vacuum soldering furnace and JD-200 laser vision lid opener offers the following collaborative advantages:

MUX400: Ensures hermeticity and low void rates in eutectic soldering through high vacuum (10⁻⁵Pa) and ±1℃ temperature control accuracy, adapting to formic acid processes and complex tooling designs.

JD-200: Utilizes laser aI vision positioning technology to achieve dust-free, non-destructive lid opening, supporting secondary packaging verification. the equipment’s micron-level laser detection aids in reducing spindle wobble by micrometers, cutting polishing time by over 50 times, reducing rework costs, and enhancing R&D efficiency. this solution has passed international reliability certifications (such as IEC standards), helping customers achieve performance improvements in high-end markets like optical communication and lidar.
