Surface Finishing
Tin Plating Post-Treatment Line
Built-to-spec surface finishing system for fabricators who need repeatable yield and predictable cycle times.
View detailsThe OSP Coating Line (WET-SF-06) is a surface finishing system engineered for printed-circuit-board fabrication. Each unit is configured around your panel size, throughput target, and automation level rather than sold as a fixed catalog item, so the specification reflects the work it actually has to do on your line.
Where the OSP Coating Line Fits in the Process
In a PCB line the OSP Coating Line sits in the surface finishing area. Correct integration with the steps before and after it is what protects overall yield, cycle time, and cost per panel, so it is specified as part of the wider flow rather than in isolation.
Key Capabilities
- Supplied as inline / automatic, with options for line integration.
- Stainless-steel wetted parts and chemically resistant construction where the process requires it.
- Safety interlocks, alarms and guarding designed for a production environment.
- Designed for low maintenance, fast changeover and high equipment uptime.
- Controlled bath chemistry for consistent finish thickness.
Typical Applications
Used to apply protective, solderable finishes for boards destined for SMT and through-hole assembly.
Configuration and Ordering
The OSP Coating Line can be supplied as a standalone unit or built into an automated line. Panel-size handling, control software, throughput, and material compatibility are configured to your production mix. As a configured-to-order system, the specification is finalized with our engineers before quotation.

Frequently Asked Questions
Which materials or board types does the OSP Coating Line support?
Supported board types include Rigid, multilayer, HDI (flex / rigid-flex optional). Other substrates can often be qualified with a short process trial — send a sample and we will confirm.
How is the OSP Coating 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.
What are the utility requirements for the OSP Coating Line?
Electrical supply is specified at 3-phase 380-415 V AC, 50/60 Hz. Compressed air, water, and exhaust connections are detailed in the installation drawing supplied before delivery.
What lead time and support come with the OSP Coating Line?
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.
