Case Study: Korean Automotive Sensor Module Manufacturer Standardizes on BONENS 3006 & 3323 for ADAS Applications

Client Profile: A Korean Tier-2 automotive electronics supplier producing LiDAR sensor interface modules and camera calibration circuits for Advanced Driver Assistance Systems (ADAS) supplied to major Korean and Japanese automakers.

Challenge

Automotive sensor modules for ADAS applications demand exceptional component reliability, compact packaging, and stable performance across the full automotive temperature range (-40°C to +105°C). The client's LiDAR interface module required both a multi-turn trimmer for precision photodetector bias calibration (ultra-compact form factor) and a single-turn low-noise trimmer for signal path gain adjustment. Previous dual-supplier strategy created inventory complexity and inconsistent quality documentation across the two component sources.

BONENS Solution

Sichuan Qixing provided a unified solution with two complementary BONENS series: the 3006 ultra-miniature multi-turn cermet trimmer for photodetector bias calibration in the most space-constrained area of the PCB, and the 3323 series low-profile single-turn cermet trimmer for low-noise signal path gain adjustment. Both series share the same glass-glaze cermet element technology, simplifying quality documentation and supplier management. Comprehensive PPAP (Production Part Approval Process) documentation was provided to support the client's automotive qualification requirements.

Results

Consolidating to a single BONENS supplier for both trimmer types generated 14% cost savings through volume bundling, reduced supplier management overhead by 67%, and delivered measurably better field reliability. The client is now evaluating additional BONENS series for next-generation ADAS sensor programs.
