Domestic "Chip" Strength | Changguang Huaxin Automotive Laser Radar Chip Passes Automotive Grade AEC-Q102 Certification
03/31
2023
Today, Changguang Huaxin's automotive LiDAR chip product successfully passed the automotive-grade AEC-Q102 certification. Coupled with the IATF16949 quality system certification obtained last December, Changguang Huaxin has acquired two entry passes into the automotive electronics industry, making it a compliant and reliable automotive LiDAR chip supplier for car manufacturers.
" What is AEC-Q certification?
Currently, most automotive manufacturers require parts to have AEC-Q certification, which is an internationally recognized automotive component product verification standard. , Passing AEC-Q certification means the product can be used in automobiles.
AECQ is developed and promoted by the Automotive Electronics Council (AEC), a group formed by major automotive manufacturers and leading U.S. component manufacturers, aimed at standardizing the reliability and qualification standards of automotive electronic components. AEC-Q102 mainly sets the criteria for discrete optoelectronic component products entering the automotive market, with testing conditions stricter than those for consumer-grade chips.
From early project preparation to later testing and validation, during the AEC-Q102 automotive certification process, Changguang Huaxin successfully passed a series of automotive-grade certification tests including environmental stress acceleration verification, life acceleration simulation verification, packaging verification, chip manufacturing reliability verification, electrical verification, and failure screening verification.
" Changguang Huaxin automotive LiDAR chip
As one of the few IDM semiconductor laser companies globally with key process production capabilities such as 6-inch epitaxy and wafer manufacturing, Changguang Huaxin consistently adheres to high standards and strict requirements in the design, production, and quality management of automotive radar chips. This time, the LiDAR chip product that passed the AEC-Q102 certification is a VCSEL array light source. With the development of LiDAR technology,
VCSELs have attracted widespread attention in the LiDAR application market due to their low manufacturing cost, small temperature drift coefficient, and ease of two-dimensional integration. Mainstream manufacturers have launched VCSEL LiDAR projects, laying a solid foundation for the application of VCSEL lasers in automotive LiDAR. Automotive LiDAR demands higher performance and reliability from VCSEL chips. Changguang Huaxin automotive VCSEL LiDAR chips feature high energy density, low divergence angle, and high efficiency, and multi-junction VCSELs used in LiDAR can achieve higher peak power with a smaller emitting area, meeting the sensing distance requirements of LiDAR, and offer advantages such as simple optical systems, miniaturization, and cost-effectiveness. In addition to VCSEL laser chips for automotive radar,
Changguang Huaxin is also actively developing automotive EEL edge-emitting lasers and 1550 nm fiber laser pump source products. As these projects progress, they will further consolidate Changguang Huaxin's market position as a full-solution provider of LiDAR light sources. VCSEL激光器芯片外，长光华芯还积极布局开发车载EEL边发射激光器及1550 nm光纤激光器的泵浦源产品，随着项目的推进，将进一步巩固长光华芯全套激光雷达光源方案提供商的市场地位。
