Based on the specifications provided, this appears to be a description of a printed circuit board (PCB) designed for a watch application, with a focus on network communication. Below is a breakdown and explanation of the key features mentioned:
1. Purpose: Watch
- The PCB is used in the assembly of a watch, likely a smart watch or a connected device, where the PCB plays a key role in supporting the electronic components needed for functionality.
2. Number of Layers: 8L (first order)
- This indicates that the PCB has 8 layers, which are typical for complex circuits requiring multiple connections and high-density routing. This is common in devices with advanced features, such as watches with network communication capabilities.
3. Plate Thickness: 0.7mm
- The thickness of the PCB is 0.7mm, which is relatively thin and indicates the need for a compact design. Thin PCBs are often required in consumer electronics such as watches to save space and keep the device lightweight.
4. Application: Network Communication
- The PCB is intended for network communication purposes, which could include components like Wi-Fi, Bluetooth, or other communication modules, allowing the watch to connect to external devices or the internet.
5. Minimum Line Width/Line Spacing: 63/63um
- The minimum line width and line spacing are both 63 micrometers (um). This defines the smallest dimensions of the copper traces and the space between them. A smaller line width allows for a more compact design, which is essential in space-constrained devices like a watch.
6. Surface Treatment: Chemical Gold, Chemical Gold + OSP
- The surface treatment options are chemical gold and chemical gold + OSP (Organic Solderability Preservative). These treatments enhance the solderability and corrosion resistance of the PCB surface.
- Chemical Gold: This provides a high-quality, durable surface that is ideal for high-frequency applications such as network communication.
- Chemical Gold + OSP: This combination adds a protective organic layer that preserves the solderability of the pads and enhances the PCB’s overall performance.
7. Blind Hole Diameter: 0.10mm
- Blind holes are holes that do not go all the way through the PCB. The diameter of these holes is 0.10mm, which is quite small and indicates the PCB is designed with high-density components in mind. Blind holes are often used to connect layers in multilayer PCBs without drilling through the entire board.
Summary:
This PCB is designed for advanced electronic watches that incorporate network communication capabilities, with a focus on a compact, high-performance design. The specifications highlight its suitability for high-density and precise applications, such as smartwatches with wireless communication features like Wi-Fi or Bluetooth. The combination of an 8-layer structure, small minimum line width, and high-quality surface treatments makes it ideal for devices where space, performance, and durability are key factors.
