Etching Machine Installation Guide

The 12-week timeline from PO to first part

Most buyers underestimate how much lead time an etching line needs on the customer side. Manufacturing and shipping takes 8-12 weeks; site preparation usually runs in parallel; installation and commissioning takes another 5-7 working days once the truck arrives. This guide walks through every step with the numbers our installation team actually sees on customer sites. If you are still comparing machines, start with our buyer's guide; if you have already chosen a GE-JM650 spray line or GE-JM650-T immersion tank, read on.

Phase 1 — Site preparation (weeks 1-8, parallel to manufacturing)

While we build the line, you build the room. Site prep is the most common cause of installation delay, so we ship a detailed site-prep manual with every PO. Four things to plan:

Floor loading and slab

The GE-JM650 spray line, fully charged with chemistry and panels, exerts a floor load of 12-15 kN/m². A standard 150 mm concrete slab on competent subgrade handles this without reinforcement. For rooftop installations or upper-floor mezzanines, get your structural engineer to verify. The GE-JM650-T immersion tank with HF chemistry is denser — 18 kN/m² when fully charged — and that always requires a slab check. The slab also needs a bundled containment curb rated for 110% of the total chemistry inventory; a GE-JM650 with full chemistry storage is typically 4500 L.

Exhaust and ventilation

Face velocity at the chamber lip must be 0.5 m/s minimum on every GE-series line. For a single GE-JM650 chamber that is roughly 800-1200 CFM depending on chamber size. For an HF titanium line on the GE-JM650-T, face velocity must be 0.5 m/s with a dedicated wet scrubber on the off-gas — neutralization with NaOH before discharge. Local environmental permits may set higher flows; check with your regulator before sizing the fan. Exhaust duct should be FRP or PP, never galvanized, because acid condensates will strip the zinc and rain down on your roof.

Electrical service

The GE-JM650 spray line ships configured for 380-415 V three-phase at 50/60 Hz, total connected load 35-45 kW including spray pump, chemistry pump, exhaust fan, and bath heater. We recommend a dedicated 80 A breaker and a clean ground (≤ 4 Ω). For sites with unstable mains or frequent brown-outs, we strongly recommend a 30 kVA online UPS on the control cabinet to prevent PLC program corruption. The PLC ships programmed and tested; you do not want a power glitch wiping the recipe library on day 3.

Water supply and quality

Final rinse water must be DI or RO with conductivity below 5 µS/cm and chloride below 5 ppm. Pre-rinse can be tap water but should be soft (< 50 ppm hardness) to prevent carbonate scale on chamber walls. We size rinse stages on the GE-JM650 for 8-12 L/min total flow depending on panel throughput. Plan a 1 m³ DI tank with recirculation pump and a 0.5 m³ pre-rinse tank; both with level switches tied into the PLC.

Phase 2 — Delivery and positioning (day 1)

A GE-JM650 ships in three crates: the chamber, the control cabinet, and the chemistry regeneration skid. The chamber crate is the heavy one — typically 2200 kg for a 600 × 800 mm chamber. You will need a forklift with at least 3-ton capacity and 2.5 m mast height. Position the chamber on its pre-installed anchor points; do not skip the anchor bolts because the chemistry sloshing in a half-full chamber will walk an unanchored frame across the floor over time. Verify level to within 2 mm/m across both axes using a digital level on the chamber rim.

Mechanical installation (positioning, leveling, utility hookup) can be done by your own contractors using the EtchMachinery pre-installation manual. We have seen good customer installs and bad ones — the difference is almost always whether the contractor read the manual cover to cover before picking up a wrench.

Phase 3 — Utility hookup (day 2)

Day 2 is plumbers and electricians. Connect:

• Exhaust duct from chamber lip to outside.
• DI and pre-rinse water lines with shutoff valves and pressure gauges.
• Compressed air at 6-8 bar for pneumatic valves and the spray oscillation cylinder.
• Three-phase power to the control cabinet; ground to the building ground.
• Chemistry feed lines from storage to the regeneration skid.
• Waste line from regeneration skid to your neutralization system.

Every utility connection is labeled at both ends with stainless tag plates that we ship with the line. Do not rely on cable colors alone — trace every line from end to end before filling chemistry.

Phase 4 — Chemistry fill and leak test (day 3)

Once utilities are live, the EtchMachinery commissioning engineer arrives and fills the chemistry loop. For an FeCl₃ spray line this means filling the chamber, sump, and regen skid with fresh etchant at 38-40° Baumé. The first fill is the most expensive one because it primes the entire loop — typically 1500 L for a GE-JM650.

After fill, we run a 4-hour leak test at operating temperature (50 °C) with all pumps running. The PLC logs any pressure decay or level drop; the engineer walks the entire loop with a flashlight looking for weeps at flanges and pump seals. Do not skip this step. A pin-hole leak that shows up on day 30 of production is dramatically more expensive than one caught on day 3.

Phase 5 — IQ/OQ (day 4)

IQ (Installation Qualification) verifies that the equipment is installed correctly — utility hookups, anchor points, safety devices, calibration certificates. OQ (Operational Qualification) verifies that the equipment operates to spec across its parameter range — bath temperature, spray pressure, exhaust flow, alarm response. The EtchMachinery engineer runs documented IQ/OQ protocols over 2 days; the customer receives a signed IQ/OQ packet for their quality system. If you are in a regulated industry (medical, aerospace, automotive IATF 16949), this packet is what your auditor will want to see.

Phase 6 — Commissioning and trial runs (days 5-6)

With IQ/OQ signed, we run production-rate trial panels through the line. The engineer sets the spray pressure, oscillation rate, bath temperature, and conveyor dwell time against the recipe we shipped from the factory. Typical trial parts include a stainless shim stock coupon, an aluminum antenna coupon, and a copper lead-frame coupon — three different metals and thicknesses to confirm the line handles the customer's planned product mix. Etch depth is measured at 5 points per panel with a calibrated micrometer; uniformity and etch factor are logged.

If trial parts are within spec, the customer signs the commissioning report. If not, we iterate on parameters — chemistry concentration, agitation rate, exposure dose on the phototool — until the customer's part passes their internal acceptance criteria.

Phase 7 — Operator training and first-part sign-off (day 7)

Standard operator training covers 6 operators over 2 days: daily startup, chemistry control, defect troubleshooting (see our troubleshooting guide), and emergency shutdown. Advanced training packages add 2 more days on chemistry regeneration tuning and PLC recipe management. All training is documented with signed operator competency records.

First-part sign-off happens at the end of day 7. The customer runs their own part on the line, in their own shift, with their own operators. The EtchMachinery engineer is on the floor for the first 2-3 hours of the customer's first production shift. Once the customer's part passes their QC, the line is handed over and the warranty clock starts.

Common installation pitfalls

Across 80+ installations, these are the issues that bite customers most often:

1. Exhaust fan undersized. Customers sometimes size for "average" CFM and forget that face velocity is a minimum, not a target. If your regulator tightens the limit, you cannot add CFM without ripping out the duct.
2. Floor drain near the chamber. Code requires it for spill containment, but if the floor drain ties to an acid-waste line without neutralization, you will fail your first environmental inspection.
3. Compressed air wet. Untreated compressed air carries water and oil into the pneumatic valves. Install a refrigerated dryer and a 0.1 µm coalescing filter on the air line.
4. DI water capacity undersized. Customers size DI for the rinse flow rate, not for the peak demand when the chamber is dumping. A 1 m³ DI tank with a 20 L/min make-up is fine for steady-state, but you want a 2 m³ tank if you ever run two chambers in parallel.
5. Chemistry storage too close to the chamber. Most codes require 1.5 m clearance between chemistry tanks and the operating face of the line for operator egress.

Frequently asked questions

How long does it take to install a GE-JM650 etching line from delivery to first part?

A typical installation takes 5-7 working days: day 1 positioning and leveling, day 2 utility hookup, day 3 chemistry fill and leak test, day 4 IQ/OQ documentation, day 5-6 commissioning and trial runs, day 7 first-part sign-off. Lead time from PO to first part is usually 12-16 weeks including manufacturing and shipping.

What floor loading do I need for a spray etching line?

The GE-JM650 spray line exerts 12-15 kN/m² when fully charged. Most industrial slabs handle this. The GE-JM650-T immersion tank reaches 18 kN/m² when fully charged — check before installing on an upper floor.

What exhaust CFM does an etching chamber need?

For an FeCl₃ spray line, face velocity must be 0.5 m/s minimum, which translates to 800-1200 CFM for a single GE-JM650 chamber. For an HF titanium line, 0.5 m/s with a wet scrubber on the off-gas. Local permits may require more.

What electrical service does a spray etching line need?

380-415 V three-phase at 50/60 Hz, 35-45 kW connected load. Most sites install a dedicated 80 A breaker and a clean ground (≤ 4 Ω). We recommend a 30 kVA UPS on the control cabinet.

What water quality do I need for the rinse stages?

Final rinse must be DI or RO with conductivity below 5 µS/cm and chloride below 5 ppm. Pre-rinse can be tap water but should be soft (< 50 ppm hardness). Rinse flow on a GE-JM650 is 8-12 L/min total.

How much chemistry storage do I need on site?

For a single GE-JM650 spray line running FeCl₃ at 42° Baumé, plan on-site storage for 2× the working bath volume (typically 1500 L per chamber, so 3000 L of concentrated FeCl₃ in HDPE tanks). Add equal volume for neutralization chemistry (NaOH) and waste treatment.

What is IQ/OQ and how long does it take?

IQ verifies the equipment is installed correctly. OQ verifies it operates to spec. On a GE-JM650 we run IQ/OQ over 2 days with documented protocols; the customer receives a signed packet for their quality system.

Do I need a waste treatment system before installation?

Yes. Spent etchant cannot go to drain in any jurisdiction we ship to. Most sites install a two-stage neutralization skid: pH adjustment with NaOH, then precipitation of dissolved metals as hydroxides, then filter press for solids.

What training comes with the installation?

Standard installation includes 2 days of operator training for up to 6 operators, covering daily startup, chemistry control, defect troubleshooting, and emergency shutdown. Advanced packages add 2 more days on chemistry regen tuning and PLC recipe management.

Can I install the line myself or do I need EtchMachinery on site?

Mechanical installation can be done by your own contractors using the pre-installation manual. Commissioning, chemistry fill, IQ/OQ, and operator training must be done by an EtchMachinery-certified engineer for warranty validation.
