Browning is the final step in the etch process and involves applying a brown tint to the PCB. This hue is used as a visual indicator of etch progress and ensures that all unwanted copper has been removed.

A PCB browning machine is a piece of equipment used in the production of printed circuit boards (PCBs) to create a dark-colored surface on the copper traces of the board for better contrast and visibility during inspection and testing. The process of browning involves the application of a chemical solution to the surface of the board, which reacts with the copper to create a dark, oxidized layer.
Features of a PCB browning machine：
- Automated operation: Many PCB browning machines are designed for automated operation, allowing for consistent and efficient production of boards.
- Adjustable parameters: The machine may have adjustable parameters such as solution concentration, temperature, and exposure time to allow for customization of the browning process.
- Safety features: To ensure safe operation, the machine may have safety features such as alarms and automatic shut-off mechanisms.
- Compatibility with different board sizes and types: PCB browning machines may be designed to accommodate various board sizes and types, including single-sided and double-sided boards.
- Easy maintenance: The machine may have features such as a self-cleaning system or easy access for cleaning and maintenance to ensure optimal performance.
When purchasing a PCB browning machine, there are several factors to consider, including:
- Production volume: The machine’s production capacity should align with your specific production needs.
- Dragon Etching machine achieves a high yield rate of 99.9% due to its high precision and controllable etching speed, which greatly improves manufacturing efficiency and reduces costs.
- And the speed aspect is highly dependent on the environment and the materials used.
- Board size and type: Ensure that the machine is compatible with the board sizes and types you intend to produce.
- The perfect machine can produce almost most materials on the market, take a look at our etching materials catalog.
- Customizability: Consider if the machine has adjustable parameters to allow for customization of the browning process to your specific needs.
- There is no limit to the number of machines Dragon etching has available, all of which are custom models, so all you need to do is describe your needs and leave the rest to Dragon Etching!
- Safety features: Look for a machine that has safety features to ensure safe operation.
- Dragon Etching machines have not had a safety incident since the beginning, which is why we are among the top in the Chinese market.
- Maintenance and support: Consider the machine’s maintenance requirements and availability of support from the manufacturer.
