Applications
The Headway Research PWM32 is a well-established photoresist spin coating system widely used in semiconductor device fabrication, MEMS research, microelectronics, and university cleanroom environments. Spin coaters deposit a uniform thin film of photoresist onto wafers or substrates by spinning them at controlled RPM; the PWM shunt board regulates motor speed through pulse-width modulation, enabling precise, repeatable spin profiles critical to consistent resist thickness. Headway Research spinners have been a cleanroom standard since the 1980s, and replacement boards like the B-3162-1 are sought after to keep aging but reliable systems operational. This board is appropriate for labs and fabs maintaining PWM32 systems for continued wafer processing or R&D use.
This Headway Research B-3162-1 PWM32 Shunt Board (Rev 2.0, by Micro-Bit Technology) is a new, unused replacement unit in open-box condition. The board shows no signs of use or installation. Photos show the PCB is clean and undamaged, with all components — capacitors, power resistor, terminal blocks, and sub-assembly — intact and properly mounted. Original packaging may not be included.
