View detailsMetal & PCB Photoresist Stripping Machine
Post-etch photoresist stripping machine that removes the cross-linked dry-film or liquid resist used as the etch mask, leaving a clean patterned metal panel. Two bulking stages swell the resist matrix; two film-removal sprays then peel and dissolve the resist into the bath. An intermediate inspection station, an acid pickling stage, and a three-cascade rinse return the panel ready for downstream surface finish.

Why This Equipment
- Two-stage bulking before strip — the resist matrix swells before being dissolved, so it lifts off in sheets rather than dispersing as fine particulate that clogs filters.
- Two-stage film removal — first pass takes the bulk; second pass finishes residue removal for paint-ready surface cleanliness.
- Built-in intermediate inspection station — operators visually confirm strip completeness before the panel enters acid pickling.
- Integrated acid pickling — removes any flash oxide formed during stripping, so the panel exits ready for plating, passivation, or coating.
- Three-stage overflow rinse — alkali residue washed to neutral pH before drying.

Where This Equipment Fits in the Production Line
Photoresist stripping is the FIRST wet stage AFTER etching. Upstream are the Spray or Vacuum Etching Machines; downstream are Chemical Cleaning, OSP, or Brown Oxidation depending on the next process step. A clean strip is required for any plating or coating that follows.

Frequently Asked Questions
Why is “bulking” a separate stage from stripping?
If you skip bulking and dump cross-linked resist straight into a hot stripper bath, the polymer dissolves as fine particulate that quickly saturates the bath and clogs the filtration cascade. Bulking pre-swells the resist so it peels off in macroscopic sheets — far easier to filter and dispose of, and gentler on the bath lifetime.
What is the warranty?
Standard one-year warranty against manufacturing defects, plus lifetime maintenance support — spare parts are stocked and shipped from Shenzhen on order.
Does the integrated acid pickle damage the metal?
No — pickle dwell is calibrated to remove the very thin flash oxide formed during stripping (Å-scale on stainless or copper) without measurable substrate loss. The same bath would be far too gentle for any meaningful surface preparation; that is the job of the dedicated Chemical Cleaning Machine.
Is the machine customized to my production line?
Yes. Every system is built around your panel size, throughput target, available utilities, and downstream process integration. Standard dimensions in the spec table are the most-ordered configurations, but length, width, and bath sequence are all configurable.
Frequently Asked Questions
What facility connections does the Metal & PCB Photoresist Chemical Stripping Machine need?
Electrical, compressed-air, water, and exhaust requirements are confirmed in the installation drawing we issue before delivery, matched to your facility's available services.
What lead time and support come with the Metal & PCB Photoresist Chemical Stripping Machine?
Lead time is quoted per order once the configuration is fixed. Installation guidance, commissioning support, and spare-parts documentation are provided so the line reaches stable output quickly.
Can the Metal & PCB Photoresist Chemical Stripping Machine be customised for our process?
Yes. Conveyor width, tooling, control options, and the surrounding handling can be adapted to your panel size, throughput target, and facility constraints. Share your specification and we will propose a configuration.
What workpiece sizes does the Metal & PCB Photoresist Chemical Stripping Machine handle?
Working size depends on the configured tooling and conveyor width. Share your largest and smallest part dimensions and we will confirm the achievable window.
