【AI-Powered Sustainable Manufacturing】A Sun ATOM Micro-Diameter Drills — Unlocking New Horizons in Micro-Hole

With large-scale AI models such as NVIDIA platforms, ChatGPT, and DeepSeek driving a new wave of artificial intelligence, the importance of semiconductor manufacturing continues to rise. Chip testing has become a critical process for ensuring yield and reliability. As a key fixture, the IC socket precisely positions pins through micro-holes, maintaining consistent contact angles and alignment within extremely tight tolerances to prevent signal interference and poor contact. The quality of micro-hole machining directly affects the electrical performance and service life of the socket, making it a core technology supporting stable testing of high-speed, high-density chips. In this sense, every successful chip relies on the precision support of its testing socket.

ATOM, a Japanese specialist in micro-diameter drilling tools, has introduced two high-performance product lines designed to address the challenges of micro-hole machining in semiconductor packaging and testing. The ADR Standard Series drills offer a minimum diameter of Ø0.02 mm and are suitable for micro-hole machining in steel, non-ferrous metals, and resins. The ADR-SV Standard Coated Series features a wear-resistant FCS coating, ideal for micro-hole machining in mild steel and high-hardness steels up to HRC 50, significantly improving chip evacuation, machining quality, and tool life.

Both series demonstrate outstanding performance in actual micro-hole machining of socket materials and have received strong market recognition. In addition to applications in engineering plastics and machinable ceramic sockets, these drills are also suitable for ceramic-filled plastics, monocrystalline silicon, aluminum, and other high-performance materials. They deliver significant value in high-precision structural manufacturing and electronic component processing.

As the exclusive distributor of ATOM in Taiwan, Yue-Wei Technology offers a comprehensive micro-diameter tooling portfolio with ready stock of both ADR and ADR-SV series, covering full sizes from Ø0.02 mm to Ø1.0 mm. With over 20 years of experience in micro-hole machining services, the company provides professional technical support and can deliver standard tools within one week—helping customers maintain superior machining quality and efficiency in the fast-evolving semiconductor industry.
