Etching Machine Manufacturer for PCB & Metal Chemical Etching

Our etching machines process stainless steel (304, 316, 430), copper, brass, aluminum, titanium, nickel alloys and most engineering metals, as well as the copper layer on FR4 for printed circuit boards. Different metals need different etchants (ferric chloride for steel/copper, acidic peroxide for aluminum, alkaline ammonia for fine-line PCB).

Tolerances down to about ±0.01–0.025 mm are achievable depending on the metal, its thickness and the machine configuration. For PCB, 25–50 µm line/space is standard on a conveyor etcher. For metal parts, minimum feature size scales with material thickness — typically 1:1 ratio.

Electronics and PCB manufacturing, automotive sensors, aerospace filtration, medical devices (titanium implants), precision mesh, nameplate and signage, decorative stainless steel, hot foil stamping dies, flexible cutting dies, and architectural panels.

Both use the same spray-etching principle. A PCB etching machine is tuned for the thin copper layer (17–70 µm) on board panels, running cupric chloride or alkaline chemistry with regeneration. A metal etching machine handles thicker (0.1–3 mm) and mixed metals, usually with ferric chloride.

Entry-level lab etchers start around $5,000–$8,500. Mid-range conveyor lines with regeneration run $25,000–$80,000. Full industrial turnkey PCB etching lines (with pre-treatment, post-treatment, wastewater treatment) are $80,000–$300,000+. Price depends on panel size, automation level, etchant chemistry, and whether regeneration is included. Send us your panel size and volume for a quote.

Spray etching uses pumped nozzles to deliver fresh etchant at high velocity to the workpiece, giving faster etch rate, better side-wall profile, and lower chemical consumption. Immersion etching submerges parts in a bath — slower, more isotropic, but better for delicate 3D parts and small batches. Industrial PCB production uses spray etching; immersion suits small-batch metal decorative work.

Conveyor spray etching machines typically achieve 25–50 microns per minute on copper with cupric chloride chemistry, and 15–30 microns per minute on stainless steel with ferric chloride. Modern conveyor lines hold ±5% uniformity across chamber width through oscillating spray headers and baffle-controlled flow.

A standard conveyor etching machine ships in 30–60 days from order. A full custom PCB etching line with pre-treatment, post-treatment, and wastewater treatment takes 90–150 days including installation, commissioning, and operator training. Containerized turnkey lines for export typically leave the factory 75–90 days after PO.
