Application Battlefield: Creating Value in Key Industrial Links

Semiconductor Manufacturing: The "Guardian" of Lithography Processes

In the chip lithography process, temperature fluctuations of only 0.1℃   are enough to cause thermal deformation of the optical components, resulting in exposure position drift . The ±0.002℃ constant temperature environment provided by Jiece equipment keeps the lithography machine's optical system stable, directly improving the chip yield.

In the etching process, temperature and humidity fluctuations can cause over-etching or under-etching. The stable environment provided by the equipment ensures the uniformity of the etching rate and ensures the integrity of the chip circuit.

Aerospace: The Unsung Hero of Micron-Level Precision

In the processing of aircraft engine turbine blades, a temperature fluctuation of 0.05℃   can cause thermal deformation of the machine tool, resulting in substandard blade processing accuracy. The constant temperature environment maintained by the Jiece environmental control cabinet ensures the blade surface accuracy and surface quality.

In aerospace material testing, the equipment precisely controls humidity fluctuations within   ±2%RH   to meet extremely stringent testing requirements.

Optical Instruments: Dual Protection of Purity and Stability

In optical lens polishing, temperature fluctuations can lead to differences in the thermal expansion coefficients between the polishing disc and the lens material, affecting the lens curvature accuracy.

A constant temperature environment ensures stable grinding precision. Simultaneously, a clean environment prevents lens surface contamination and avoids defects in subsequent coating processes.

New energy battery: Dual control of moisture and temperature

In the electrode coating process, humidity changes will affect the moisture content of the slurry, leading to uneven coating. The extreme measurement equipment provides   ±0.5%RH humidity stability ，ensuring consistent electrode coating.

In the battery assembly stage, a constant temperature environment avoids sealing problems caused by differences in thermal expansion and contraction of different materials, preventing battery leakage from the source.
