Technical Specifications:​ 32 temperature input channels with thermocouple/RTD conditioning, PID closed-loop control, proprietary tool backplane communication, modular circuit-card format with extractor handles, operating ambient 0°C to +50°C.

Performance Parameters:​ Multi-channel input polling, analog-to-digital conversion for thermal sensors, PID output to heater/zones, backplane data exchange with the tool host, continuous chamber thermal monitoring.

Materials And Structure:​ Industrial multilayer PCB, thermocouple/RTD conditioning components, PID control logic, backplane edge connector, faceplate with handles and status indication.

Working Principle:​ The card reads zone temperatures from thermocouples or RTDs, compares them with setpoints, computes PID correction and drives heater control outputs while reporting status and alarms to the host controller over the backplane.

Application Scenarios:​ Lam and legacy Novellus CVD thermal-management platforms, multi-zone reactor heating, wafer uniformity control and semiconductor thermal-process cabinets.

Installation Requirements:​ Install only in the assigned chassis slot with full power isolation, use ESD handling, verify slot mapping, thermocouple/RTD type and polarity, confirm backplane jumper and communication configuration before energizing.

Usage Notes:​ Do not hot-swap the card while the rack is powered. Verify all 32 channels through host diagnostics after installation. Check thermocouple polarity and sensor calibration offsets to prevent runaway heating or false temperature readings.
