Etching systems are industrial machines used to remove material from substrates using chemical, plasma, or wet etch processes for PCBs, semiconductors, metals, and decorative finishes. Equipment ranges from benchtop wet etchers to inline plasma/RIE units with process control, exhaust filtration and automation. Buyers prioritize process compatibility, throughput, waste handling, safety features, and the availability of spare parts and consumables when evaluating used or refurbished units.
Verify process compatibility (chemical vs. plasma), chamber and fixture condition, integrity of seals and pumps, controller/software status, maintenance logs, exhaust and filtration systems, and availability of spare parts and consumables. Ask about prior processes that may have contaminated the unit.
Decontaminate and neutralize all chemicals, drain fluids, disconnect gas and power, and document hazardous-materials history. Use a transporter experienced with lab/semiconductor equipment, crate and secure components, insure the shipment, and prepare required hazmat paperwork and permits.
Routine tasks include chamber cleaning, filter and pump replacement, vacuum seal inspection, gas-line leak tests, controller calibration, and proper waste neutralization/disposal. Keep logs, follow manufacturer service intervals, and replace consumables proactively to maintain process consistency.
