Summary
The invention discloses a method and a circuit board for performing selective electroplating on a surface of a circuit board, comprising: covering a surface of the circuit board with a conductive layer; covering an unplated area on the surface of the conductive layer with an anti-plating protective layer; Electroplating of the electroplated protective layer covered by the electroplated protective layer to obtain a first surface treated electroplated metal layer; performing a non-first surface treatment, wherein on the surface formed by the last surface treatment, on the non-first surface The treated electroless plating region covers the anti-electroplating protective layer; and electroplating is performed on the electroplated region not covered by the anti-plating protective layer to obtain the non-first surface-treated electroplated metal layer; the anti-electroplating protective layer is removed, and the etching is not performed A conductive layer covered by a plated metal layer. The above method eliminates the need to arrange plating leads on the surface of the board, and avoids the influence of the plating leads on the wiring density.

Engineered wood flooring trends include the following:
1. Environmental protection materials: With the improvement of people's awareness of environmental protection, more and more consumers choose to use environmental protection materials. Engineered wood flooring is a combination of wood and man-made materials. Compared with solid wood flooring, the wood used is more economical and can reduce the cutting of natural forests.
2. High-quality appearance: Engineered wood flooring has the natural beauty and texture of solid wood flooring, and it can also create more diversified appearance effects through processing technology. Consumers are increasingly demanding the appearance of the floor, Engineered wood flooring can meet their needs for high-quality appearance.
3. Durability and wear resistance: Engineered wood flooring adopts a multi-layer structure to make it have high durability and wear resistance. This makes it suitable for use in high-traffic areas such as kitchens and hallways in commercial premises and homes.
4. Convenient installation and maintenance: Engineered wood flooring is more convenient to install than solid wood flooring. It can be installed by locking system or adhesive, reducing installation time and cost. At the same time, Engineered wood flooring is also easier to maintain than solid wood flooring, and only needs regular cleaning and maintenance.
5. Diversified design and color choices: Engineered wood flooring provides a rich variety of design and color choices to meet consumers' needs for personalization and customization. From classic wood grain design to modern stone and metal grain design, consumers can choose the right floor according to their own preferences and home style.
In general, the popular trend of Engineered wood flooring is to develop in the direction of environmental protection, high quality, durability, convenient installation and maintenance, and diversified design and color selection. These trends reflect changes in consumer demand and preferences for flooring.
