Product Description

Product Description:

The Double-Sided PCB, boasting a conductor space of just 3 mil, is an advanced solution for a wide range of electronics applications. This Two-Sided Circuit Board is meticulously designed to cater to high-precision requirements, ensuring that even the most intricate of circuits can be accommodated with ease. As technology progresses, the demand for overlength PCBs that can support complex circuits without compromising on performance has grown. Our product is a testament to this evolution, offering unmatched reliability and efficiency.

One of the most notable features of this Double-Sided Printed Board is its solder resist color. The vibrant green hue not only provides a clear contrast for easy inspection of solder joints and pathways but also acts as a protective layer against oxidation and corrosion. This feature is especially important for boards that are exposed to harsh environments or are in use for extended periods. The green solder resist is a mark of quality and durability, safeguarding the circuitry and ensuring the longevity of the PCB.

Surface treatment is a critical factor in the performance of PCBs, and our Double-Sided PCB is no exception. It comes with an Immersion Gold surface treatment that offers excellent conductivity and resistance to wear. This treatment is known for its ability to provide a flat surface which is ideal for fine-pitch components or for applications requiring repeated assembly and disassembly. Immersion Gold treatment also enhances the electrical performance of the PCB, making it a preferred choice for high-frequency or high-speed applications.

The surface finish of a PCB can greatly influence its solderability and protection against oxidation. Our product offers a range of surface finishes, including HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), Immersion Tin, Immersion Silver, Gold Finger, and OSP (Organic Solderability Preservative). These options provide versatility to meet different assembly and performance requirements. HASL is a widely used surface finish that provides a good solderable surface and is cost-effective. ENIG offers superior surface planarity and is excellent for fine-pitch technology, while Immersion Tin and Immersion Silver are ideal for flat surface requirements. Gold Finger finish is typically used on the connecting edges of PCBs for repeated insertion, and OSP is a surface finish that is great for those looking for a lead-free solution.

With a standard PCB thickness of 1.6mm, this Double-Sided PCB strikes the perfect balance between strength and flexibility. This thickness is the industry standard and is preferred for its mechanical robustness and ease of handling during the assembly process. It is thick enough to provide a solid foundation for the components while being thin enough to allow for efficient thermal management and electrical performance. Whether used in consumer electronics, automotive applications, or industrial equipment, the 1.6mm thickness ensures that the board can withstand the rigors of everyday use without sacrificing functionality.

In summary, the Double-Sided PCB with a conductor space of 3 mil is a superior product that combines advanced features with robust construction. The green solder resist color, various surface treatment options, and a range of surface finishes make it adaptable to various applications and environments. The 1.6mm thickness ensures durability and performance, making it a go-to choice for both standard and overlength PCBs requirements. Whether for complex multi-component assemblies or for simple circuits, this Two-Sided Circuit Board is engineered to deliver consistent, high-quality results that our customers can rely on.

The Double Sided PCB, also known as Dual-Sided PCB, has become an essential component in various electronic applications due to its versatility and efficiency in connecting electronic components. With a standard PCB thickness of 1.6mm, it ensures durability and firmness in various assembly scenarios. The silkscreen color options available for this PCB include white, black, and yellow, which offer not only clear marking for component placement but also customization options to match different design aesthetics and requirements.

One of the standout features of the 1.5m double-sided PCB is its 100% E-test guarantee, which ensures that each PCB is rigorously tested for electrical performance before being dispatched. This level of quality control is crucial for applications where reliability and safety are paramount. The raw material used in the construction of these Double-Plated PCBs is FR-4, a well-known and widely used flame-retardant substrate that provides excellent mechanical strength, thermal stability, and electrical insulation.

Given its robust build and reliable performance, the Double Sided PCB finds its application in a host of scenarios. It's commonly used in the manufacturing of industrial controls where the double-sided design allows for a complex yet compact circuitry that can handle multiple functions within a small footprint. This type of PCB is also prevalent in automotive electronics, where the durability of the FR-4 material and the rigorous E-testing ensure long-term reliability in the harsh conditions experienced by vehicle electronics.

Consumer electronics is another arena where these dual-layer PCBs shine. From smartphones to home appliances, the 1.5m double-sided PCB is instrumental in providing the necessary connectivity while maintaining a slim profile, which is essential for modern, sleek product designs. Additionally, in the realm of medical devices, where precision and reliability are non-negotiable, the Double-Plated PCBs are highly valued for their consistent performance and adherence to stringent quality standards.

In summary, the Double Sided PCB with its 1.6mm thickness, variety of silkscreen colors, and the guarantee of a 100% E-test, is a versatile product suitable for numerous applications. From automotive to consumer electronics, industrial controls, and medical equipment, the quality and reliability of these PCBs make them an indispensable component in today's electronic product landscape.
