Case Study on Thin Film Submounts in the Telecommunications Industry

We will introduce a case where thin-film submounts were delivered to a telecommunications company with limited experience and knowledge regarding submounts!

Customers in the telecommunications industry have limited experience and knowledge regarding sub-mounts, which has led to an inability to engage in equal discussions. As a result, most specifications were determined based on proposals from manufacturers, leading to issues such as defects arising later. Our company provides detailed technical explanations and considerations for each of the customer's concerns and requests, allowing us to make proposals on the spot. As a result, we created a specification document and held follow-up meetings to ensure the customer fully understood it before finalizing and delivering the document, which led to very appreciative feedback from them. [Case Summary (Excerpt)] ■ Concerns about sub-mounts - Limited experience and knowledge regarding sub-mounts - Inability to engage in equal discussions with the sub-mount manufacturer found - Most specifications were determined based on proposals from the manufacturer, resulting in defects later on *For more details, please refer to the related links or feel free to contact us.

Cross-edge microfabrication CuW submount

Sub-mount capable of controlling sharp edges and warping.

The "CuW Submount" is a submount for heat sink applications of high-output LD modules. It allows for control of sharp edges and warping to achieve alignment during LD bonding and efficient heat dissipation. Additionally, it enables control of excess solder during AuSn deposition in the LD bonding area. 【Features】 ■ Control of sharp edges and warping is possible ■ Control of excess solder is possible ■ Suitable for high-output semiconductor lasers *For more details, please refer to the PDF document or feel free to contact us.

Cross-edge microfabrication Cu-AlN-Cu submount

Achieving both high thermal conductivity and insulation! Submounts for high-power semiconductor lasers.

The "Cu-AlN-Cu submount" is a submount designed for high-power semiconductor lasers. The three-layer structure of Cu-AlN-Cu achieves both high thermal conductivity and insulation. Additionally, by optimally controlling the thickness of the Cu plating layer in terms of thermal expansion rate, it enables CTE matching with LD elements, facilitating higher power output and longer lifespan. Moreover, the design allows for a high degree of freedom in shape. 【Features】 ■ Ensures high thermal diffusion and insulation through the composite structure of Cu plating and AlN ■ Controls the coefficient of thermal expansion (CTE) ■ No pullback required at the critical edge of the LD mounting surface ■ Compatible with AuSn and AuGe solder deposition ■ Sharp edges improve the alignment of LDs ■ Thick Cu application possible (less than 100μm) *For more details, please refer to the PDF document or feel free to contact us.
