ICC News (Editor: Cecilia) Today, optical networks are evolving into a new generation of all-optical bases with digital and comprehensive carrying capabilities, bringing a new round of development opportunities to the optical communication industry chain. Recently, Xunshi interviewed the optical chip Wafer/Die/COC aging and test equipment and service provider – Shanghai Philae Testing Technology Co., Ltd. (Shanghai Philae for short) to understand the value of chip inspection and verification for optical chips and optical communication networks.

Liu Libo, deputy general manager of Shanghai Philae, introduced: The company was established in 2018 and is positioned in the testing of optical chips (from wafer to COC) and AOI testing. Provide professional optical chip technology, testing, aging and reliability verification equipment and foundry services, for 3D sensing field, consumer electronics and optical communication fields, support many optical chips (VSCEL/DFB/DBR/Pump Laser/Silicon photonics, etc.) .

At present, the company has successfully established stable cooperative relations with well-known equipment manufacturers, and has sold more than 100 reliability test equipment to them. The optical module is the core component of the optical network, and the optical chip provides the transmission capability for the optical module, and its service life and working performance affect the connection quality of the optical network. Strict and efficient chip testing and reliability verification are key processes to ensure product consistency and high quality. The optical communication industry has iterated many times. Qualified high-speed optical modules must undergo rigorous quality verification. Optical chips are the primary detection object as the biggest source of failure. At present, most optical chip manufacturers cannot cover all aspects, especially chip-level aging and reliability testing, which provides market space for Shanghai Philae’s professional testing services.

Liu Libo of Philae Patent and Certificate Wall said that in response to the strong demand and process characteristics of the optical communication market, Shanghai Philae deployed teams, products and services in advance. The company has more than 90 employees, including a skilled R&D team with rich experience in the field of optical chip manufacturing. A deep understanding of processes and applications.

In terms of products, the VCSEL test system developed by the company supports LIV+ spectral testing, CW and QCW conditions can be freely configured, and TEC+ water cooling is used for temperature control, with high temperature stability and large controllable range, which can be applied to Wafer/Die/COB package single VCSEL or VCSEL array testing.

COC test bench (left) and CCO aging system (right) For the aging test commonly used in optical chips, the company has launched a medium and low power laser aging platform. The platform uses mature software that runs for far more than 20,000 hours, supports platform early warning, and real-time data. Tips and uploads. The temperature control system is an independent heating system or a heating and cooling system, which can be flexibly configured with different temperature zone conditions. The platform has COC online optical power monitoring system. The company is the only two test equipment manufacturers in China that can ship this function, and it has also obtained EU certification in 2020.

Liu Libo, deputy general manager of Shanghai Philae, the Wuxi base production line, said: The laser aging platform adopts fully automatic production and debugging, which can achieve rapid delivery within 2 months. At present, more than 100 units have been delivered and operated in batches. In addition, Shanghai Philae also launched a test calibration system, precision furniture, and oven-type aging system for COB and TO packaged products, aiming to provide customers with complete optical chip testing services.

Wuhan Clean Workshop Company expects that the localization of optical communication core optical chips will continue to rise, breaking through the foreign monopoly of a variety of high-speed optical chips. The service base is equipped with a 600-square-meter 10,000-level purification workshop, and a 3,000-square-meter Wuhan manufacturing service base, which is also equipped with a 1,300-square-meter 1000-level and 10,000-level purification workshop. Shanghai Philae also insists on independent and controllable test equipment core components, develops low-cost driving power supply, independently designs precision fixtures, and develops system software that is stable, recoverable and easy to correct errors, so as to ensure the reliability of equipment services to the greatest extent.

At present, the optical chip industry chain is undergoing continuous iterative evolution. Shanghai Philae will stick to key supporting testing links and build an advanced optical chip aging and reliability testing service platform to help the optical chip industry and customers achieve greater market value in the future. .
