High-Speed 8000 RPM Vacuumless Spin Coater for 4 Inch Wafers
Product Introduction
The Lith-KJ-4A Spin Coater employs an advanced power supply system where the motor and control units operate on independent power sources. Its speed regulation system utilizes a high-interference-resistance microcontroller, ensuring exceptional speed stability within a broad range of 1000–8000 RPM.
The machine automatically stops after the preset homogenization time, completing the entire coating cycle.

The coating process consists of two distinct phases:
· Phase 1 (SPD1 & T1): Low-speed rotation for gradual dispersion of film-forming liquid, completing the glue dispensing stage.
· Phase 2 (SPD2 & T2): High-speed rotation for uniform distribution of the liquid on the substrate, achieving precise film homogenization.
The Lith-KJ-4A is designed for processing liquids, gels, and flowable pastes, enabling rapid formation of uniform thin films on substrates through controllable high-speed rotation. It features a grooved polypropylene sample chuck for secure, non-damaging substrate fixation. Customizable template slots accommodate varying substrate shapes and sizes.
