Surface Finishing
HASL Post-Treatment Line (Leaded and Lead-Free)
A configured-to-order surface finishing system for PCB production lines, built and supported in-house.
View detailsAs a surface finishing machine, the ENIG Gold Line (WET-SF-04) is intended for fabricators who need repeatable output and predictable cost per panel. The system is assembled and tested in-house, then integrated to match the rest of your production line.
How It Works in Production
During the surface finishing stage the ENIG Gold Line processes each panel to a repeatable standard. Process values are driven by recipe, so results stay consistent across shifts and operators rather than depending on manual judgement.
Key Capabilities
- Controlled bath chemistry for consistent finish thickness.
- Even coverage across the panel for solderability and shelf life.
- Process options for ENIG, OSP and immersion finishes.
- Recipe management and process logging via the plc + hmi touchscreen.
- Supplied as inline / automatic, with options for line integration.
Common Use Cases
Used to apply protective, solderable finishes for boards destined for SMT and through-hole assembly.
Configured to Your Line
This is not an off-the-shelf machine. We confirm your panel size, throughput target, and facility services first, then propose a configuration of the ENIG Gold Line that fits. Installation guidance and commissioning support are included so the line reaches stable output quickly.

Tell us your panel size, throughput, and automation requirements for the ENIG Gold Line. Our engineers will respond with a tailored configuration and price, usually within one business day.
Frequently Asked Questions
What throughput can the ENIG Gold Line achieve?
Typical throughput is Up to 90 panels/hour. Actual figures depend on material thickness, feature density, and the quality target, so treat the rated value as a planning baseline rather than a guarantee.
Can the ENIG Gold Line 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 does the ENIG Gold Line do in the production line?
The ENIG Gold Line is configured for a specific stage of the wet-processing or precision-machining sequence. It is usually integrated with the handling and rinse stages around it so that throughput and surface quality stay consistent batch to batch.
How is the ENIG Gold Line controlled and operated?
Control is handled by PLC + HMI touchscreen. Operators set recipes through the interface, and process values are logged for traceability and repeatability.
