Harmoni
Focused on miniature precision electronic components; its key breakthrough lies in high-end semiconductor chip test probes, which have entered the supply chains of top-tier international chipmakers.
Broke the long-standing monopoly of overseas companies in high-end semiconductor test probes; its probe products have been successfully used in the chip testing processes of leading global GPU/CPU manufacturers.
Company Overview
Founded in 2012 and headquartered in Suzhou, Jiangsu, Harmoni was listed on the STAR Market in 2021. The company is dedicated to the R&D and manufacturing of miniature precision electronic components, with its core product being micro probes used for chip outgoing testing.
Every AI chip must undergo electrical performance testing before leaving the factory. Test probes are essential consumables that connect the test equipment to the chip's pins. As AI chips become increasingly dense with smaller pin pitches, the material and process requirements for probes grow ever more stringent. Harmoni is the domestic pioneer in this highly specialized segment.
Core Business
Semiconductor Test Probes
Used in wafer probing (CP) and final testing (FT), these probes contact the chip's micro pins to perform electrical tests.
MEMS Probe Cards
A high-end test solution for advanced-process chips, with probe pitch scalable down to the micron level.
Market Landscape
| Dimension | Data |
|---|---|
| Global test probe market | Pioneer in domestic substitution |
| Major overseas competitors | Yamaichi (Japan), Johnstech (US) |
Risks & Summary
Harmoni is another severely undervalued AI core consumables company—often overlooked alongside "PCB micro-drills." Every AI chip requires test probes for verification before shipment, so as AI chip shipments surge, the consumption of test probes will grow in tandem.
