As smartphones, secondary batteries, and semiconductor components continue to become smaller and thinner, the challenges faced on press processing floors are also intensifying. In extreme environments where ultra-thin materials—less than 0.1 mm thick—are stamped more than 1,000 times per minute, conventional punching oils can no longer withstand the demands.

In the era of technological super-gap competition, the need for next-generation precision punching oils used in high-precision electronic components is rapidly increasing.

Today, we will explore the key technical challenges in electronic component processing and the “next-generation precision punching oil” designed to solve them.

1. Three Major Technical Challenges in Electronic Component Processing

As ultra-thin materials and high-speed press operations become standard, conventional punching oils face the following limitations:

① Boundary Lubrication Issues with Ultra-Thin Materials

Ultra-thin materials with thicknesses ranging from 0.05 to 0.3 mm have extremely shallow deformation zones. In such cases, the oil film thickness can become thinner than the surface roughness of the material, leading to direct contact between the die and the workpiece.

Result: Adhesive wear and micro welding occur → Conventional viscosity design is insufficient to protect the die.

② Thermal–Viscosity Instability in High-Speed Pressing (Over 1,000 spm)

In high-speed operations exceeding 1,000 strokes per minute, instantaneous contact temperatures rise sharply.

Result: Rapid viscosity drop and accelerated oxidation → Lubrication imbalance → Increased micro burr formation and die wear.

③ Critical Residue Formation Mechanism

In electronic components, residue is not merely a cosmetic issue. High-temperature oxidation by-products or thermally decomposed additives can leave harmful residues that are critical in downstream processes.

Result: Increased cleaning time, ionic contamination, plating defects, and bonding failures—ultimately leading to serious quality incidents.

2. Four Core Solutions of Next-Generation Precision Punching Oil

To overcome these challenges, next-generation punching oils incorporate advanced technologies such as:

• Enhanced Extreme Pressure (EP) Performance:
  Minimizes die wear and prevents micro-cracking even in boundary lubrication conditions.
• Ultra-Low Residue Design:
  Reduces post-evaporation residues to near-zero, shortening cleaning processes and fundamentally blocking contamination risks in electronic components.
• Improved Thermal Stability:
  Maintains viscosity stability even at elevated temperatures, ensuring consistent dimensional precision during high-speed operations.
• Excellent Cleanability & Degreasing Performance:
  Easily removable with IPA or hydrocarbon-based cleaners, significantly reducing overall process costs.

3. Differentiation from Conventional Products
