Wet Chemical Etching Machine
Production-grade wet chemical acid etching machine that sprays etchant across copper-clad laminate, aluminum substrate, or stainless steel plate to dissolve the exposed metal and reveal a patterned circuit, mesh, or precision part. Each line is configured to the customer’s production capacity — single-stage development, three-in-one developing + etching + film-removal, or fully integrated photoresist-coater + UV-exposure + etch + strip cells are all available.
Why This Equipment
- Customized to your production capacity — every line is built around the customer’s panel size and throughput target, not sold as a one-size-fits-all SKU.
- Process library backed by an in-house etching factory — every chemistry shipped has been proven on our own production runs first.
- Closed-loop bath chemistry with SG, pH, and temperature feedback to the replenishment manifold.
- Independent top and bottom spray nozzle banks for true double-sided through-etching uniformity.
- Sheet-by-sheet traceability — bath conditions and conveyor speed logged per panel for QA.

Design Priorities & Process Discipline
The platform is engineered to four priorities: bath chemistry stability, conveyor uniformity, spray-pressure uniformity, and rinse cascade discipline. In practice it is the temperature loop and the spray nozzles that move output yield from 95% to 98%; everything else is supporting infrastructure.
- Closed-loop bath chemistry — SG and pH sensors feed a replenishment manifold.
- Dual-bank nozzles — independent top and bottom spray for double-sided etching uniformity.
- Conveyor traceability — sheet-by-sheet ID logged with bath conditions for QA.
- Acid-resistant wetted parts — PVC, PVDF, or Hastelloy C-276 depending on chemistry.
- Energy recovery — heat exchanger between hot rinse exit and cold feed water reduces line steam demand.

Frequently Asked Questions
What materials can this machine handle?
This machine is engineered for the material coverage cited in the specification table above. Bath chemistry and wetted parts are selected at build time to match the customer’s actual metal and process mix.
What support is offered after delivery?
Standard packages include on-site commissioning, operator training, and one year of remote process support. Spare-parts kits and bath-titration consumables are quoted separately.
Are CE / UL / SEMI compliance packages available?
Yes. Compliance packages are available as engineering options. Specify at order time so wetted parts, electrical, and emergency-stop circuits are sized accordingly.
What is the typical lead time from order?
Production lead time is typically 8 – 14 weeks depending on configuration. Plug-and-play bench units are usually available faster.
