Product Description

Product Description:

The Two Layer PCB, also commonly known as Bi-Layer PCB or Dual-Sided Printed Wiring Board, is a high-precision electronic component that is essential to a wide range of electronic devices. This Double-Plated PCB is meticulously crafted to support complex circuits, providing an efficient pathway for electrical connectivity between various electronic components. Designed to cater to advanced technological needs, the Two Layer PCB is made from durable FR-4 raw material, ensuring a robust and reliable foundation for electronic assemblies.

One of the most striking features of this Dual-Sided Printed Wiring Board is its availability in multiple color options, including the traditional Green, the sleek Blue, and the vibrant Yellow. These color options not only add an aesthetic touch to the PCB but also assist in tracing and identifying tracks and components during assembly and maintenance. The colored surface aids in enhancing the visual clarity of the solder mask, which is crucial for ensuring the integrity of solder joints and protecting against short circuits.

When it comes to precision and functionality, the Two Layer PCB does not compromise. It boasts a minimum hole diameter (Min Hole Dia) of 0.075 mm, allowing for the placement of fine pitch components and ensuring the accommodation of miniaturized parts that are increasingly common in modern electronics. This level of precision is a testament to the advanced manufacturing processes employed in the production of these PCBs, which are geared towards meeting the exacting standards of today’s technology.

Another cornerstone of the Double-Sided PCB's reliability is the 100% Electrical Testing (E-test) feature. Every PCB that leaves the production line is subjected to rigorous electrical tests to ensure that there are no defects or discontinuities in the conductive pathways. This commitment to quality guarantees that each Bi-Layer PCB functions as intended, providing peace of mind to customers who depend on these components for their critical applications. The 100% E-test ensures that issues such as opens, shorts, and insufficient isolation are identified and rectified before the PCBs are integrated into their final applications.

The use of FR-4 as the raw material for the Two Layer PCB is a conscious choice that reflects the product's emphasis on quality and durability. FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant. It is widely recognized for its high mechanical strength, excellent electrical insulation properties, and good chemical resistance. The FR-4 material also provides stability under varying environmental conditions, making the Two Layer PCB suitable for a wide range of operating temperatures and environments.

In summary, the Two Layer PCB represents a perfect blend of form and function. Whether it's referred to as a Bi-Layer PCB, a Dual-Sided Printed Wiring Board, or a Double-Plated PCB, it stands as a testament to advanced PCB technology, offering reliability, precision, and versatility. The green, blue, or yellow colored options enhance its visual appeal and functionality, while the minimum hole diameter of 0.075 mm ensures compatibility with modern miniature components. The 100% E-test feature and the use of high-quality FR-4 raw material further cement this product's position as an essential component in the realm of electronics manufacturing.

The Double Sided PCB, also known as the Dual-Sided Printed Wiring Board, is an essential component in the world of modern electronics, offering a reliable and efficient means of connectivity between components on both sides of the board. Fabricated from FR-4, a widely-recognized raw material for its flame-retardant properties and electrical insulation performance, these PCBs demonstrate an enduring structure with a standard thickness of 1.6mm, ensuring a sturdy base for a variety of applications.

One of the distinctive features of this Double Sided PCB is its extra-long design, which provides an ample surface area for complex or elongated circuit patterns, making the Extra long double-sided PCB an ideal choice for advanced industrial controls, telecommunications, and specialized computing equipment where space is at a premium and circuit complexity is high. Moreover, the precision of the board is highlighted by its minimum hole diameter of 0.075 mm, which allows for the accommodation of minute components and leads to high-density interconnections, crucial for sophisticated electronic assemblies.

The versatility of silkscreen color options, including white, black, and yellow, facilitates clear component labeling and identification, enhancing the assembly process and ensuring ease of maintenance and repair. This attribute is particularly beneficial for applications where multiple PCBs are used within a single system and clarity is essential for both assembly technicians and service engineers.

Ensuring the Double Sided PCB reaches its destination safely and promptly is a top priority, and that's where the array of shipping options comes into play. Customers can choose from international express couriers such as DHL, UPS, EMS, TNT, and FedEx, which offer speedy and reliable delivery services. For larger orders or when cost-effectiveness is a more significant concern, sea transport is also available, providing a balance between efficiency and economy.

Applications for the Extra long double-sided PCB range from consumer electronics, where the dual-sided design maximizes space efficiency in compact devices, to automotive industries, where long-lasting and dependable performance is required in harsh environments. The medical sector also benefits from these PCBs, using them in critical diagnostic equipment and patient monitoring systems where consistent and fault-free operation is paramount. In the realm of aerospace and defense, the robustness of FR-4 material, combined with the board's reliable electrical properties, makes it an excellent choice for mission-critical systems where failure is not an option.

In conclusion, the Double Sided PCB's combination of high-quality material, precision manufacturing, customizable features, and flexible shipping options makes it an invaluable product for an extensive range of applications and scenarios. Its capacity to support intricate electronic circuits across diverse industries is a testament to the PCB's adaptability and the technological advancement it represents.
