With the advancement of laser technology, its range of applications is also expanding. From infrared to ultraviolet, lasers are utilized in various fields such as measurement, spectroscopy, optical communication, optical data processing and storage, fiber optic communication, and medical devices. Moreover, with the increasing demand, the manufacturing of high-power laser diodes, for example, has become one of the main mass production processes. To produce high-power lasers in large quantities, die bonding equipment is required, which must maintain high precision and reproducibility while accommodating variations in the size and type of many different components, and achieving high production efficiency in the assembly of finished products. This technical paper provides an explanation of the fully automated assembly process for high-power laser diodes, including general process parameters, bonding conditions, and process steps, and introduces solutions to typical challenges faced during laser diode manufacturing, such as the bonding quality of Au80Sn20, the bonding process, and various factors arising from materials and components themselves. *For more details, please refer to the PDF document or feel free to contact us.*

In applications such as cutting, welding, and marking, fiber laser solutions are increasingly replacing traditional methods. In recent years, the manufacturing costs of semiconductor laser chips have been continuously reduced, but the current single largest cost factor is in assembly and packaging, primarily due to the manual processes involved in second-level packaging where the CoS is attached to the heat sink. To address this issue, Finetech has developed, evaluated, and provided an automated solution for packaging CoS to heat sinks using new bonding technologies. This technical paper will explain this. *For more details, please refer to the PDF document or feel free to contact us.*

Fine Tech's laser-assisted die bonding technology is suitable for chip-to-substrate (C2S) and chip-to-wafer (C2W) applications that require precise control of process speed, accuracy, and localized heating. In particular, rapid temperature cycling minimizes the risk of surface oxidation and enables the shortening of process cycles in production environments where temporal optimization is required. In continuous bonding processes at the substrate or wafer level, each chip is heated only once. Additionally, unlike area heating, localized laser heating does not require extensive equipment to prevent thermal expansion. Laser-assisted die bonding with such features is an effective technology newly added to Fine Tech's assembly and packaging technology. *For more details, please refer to the PDF document or feel free to contact us.*

The packaging of optoelectronics (photoelectronic components) units is one of the important applications in microassembly. In the recent field of photonics, multiplex transmitters and receivers with high-density packaging targeting high bandwidth, as well as assemblies that combine them, have become crucial elements. Consequently, high placement accuracy is required for the bonding of these components, and various assembly technologies are utilized. This technical paper discusses the challenges associated with these components and Fine Tech's solutions for the assembly of VCSELs and photodiodes, as well as relative high-precision bonding for single components and array components, handling of small components, safe transfer of adhesives, and advanced tool design for components with contact prohibition areas. *For more details, please refer to the PDF document or feel free to contact us.*

Thermal compression bonding is a quick and easy method for reliably joining flip chips. Many bonding processes, such as eutectic soldering implemented with load in laser bar soldering, are fundamentally classified in this category. This technical paper focuses on specific thermal compression processes used in combination with gold stud bumps or indium bumps. Flip chip bonding using this bonding method has many advantages and excellent bonding characteristics. Nevertheless, as this document indicates, it is still a niche technology and not widely adopted. Here, we provide a general overview of the process and its parameters. We also address common challenges when adopting this technology and introduce ways to solve them using the FINEPLACER die bonding equipment. *For more details, please refer to the PDF document or feel free to contact us.*
