Product Description

FR-4 Immersion Gold Double Sided PCB 100% E Test HASL/ENIG 0.075 Mm Min Hole Dia

Product Description:

The Double Sided PCB, also known as a Twin Layer PCB, is a pivotal component in the realm of modern electronic devices. This type of circuit board is fundamentally characterized by its dual-layered conducting material, which significantly enhances the complexity and functionality of the design. By employing a Double-Sided Printed Board, manufacturers can streamline connectivity and circuitry in a compact and efficient manner, thus facilitating the creation of more sophisticated and space-saving electronic assemblies.

Our Double Sided PCB boasts an industry-standard thickness of 1.6mm, which is a common requirement for a broad range of electronic applications, from consumer products to sophisticated industrial equipment. The choice of FR-4 as the raw material for the board is a testament to the industry's preference for reliability and durability. FR-4 material is known for its excellent electrical insulation, as well as its substantial mechanical strength, thermal resistance, and moisture resistance, making it an ideal substrate for long-lasting PCBs.

An essential feature of our Double Sided PCB is the solder resist color, which is the universally recognized green. This green solder mask provides a stark contrast against the silver of the solder and the gold of the component leads, which simplifies the process of visual inspections and reduces the risk of solder bridging between closely spaced pads. The green solder mask is not just a practical component but also an aesthetic one, as it gives the PCB its signature look that is widely associated with electronic circuitry.

In terms of quality assurance, each PCB undergoes a rigorous 100% E-test (Electrical Test) to ensure that every board delivered to our customers is free of shorts, opens, or any other defects that could compromise the performance of the PCB. This full-scale electrical testing is a cornerstone of our commitment to providing only the highest-quality products to our clients, ensuring that the functionality and reliability of the PCB meet the stringent standards expected in the industry.

For those requiring an Extra long double-sided PCB, our manufacturing capabilities enable us to meet such specifications with precision and efficiency. An extra-long PCB allows for extended circuit designs, which are often necessary in larger-scale electronic applications. Whether your design calls for a standard-sized board or an elongated version, our production lines are equipped to deliver PCBs that match your exact requirements.

Understanding the need for timely delivery in the fast-paced world of electronics manufacturing, we provide a range of shipping options to suit every timeline and budget. Customers can choose from express couriers like DHL, UPS, EMS, TNT, and FedEx, ensuring that their PCBs arrive as quickly as possible. For larger orders or less time-sensitive deliveries, sea transport is also available, offering a cost-effective solution with a broader delivery window. Regardless of the chosen shipping method, we take every precaution to ensure that the PCBs are packaged securely and arrive at their destination in perfect condition.

Our Double Sided PCB is a robust, reliable, and versatile solution for your electronic circuitry needs. Combining the strength and stability of FR-4 material with the functional benefits of a twin-layer design, and backed by comprehensive electrical testing and flexible shipping options, our PCBs stand as a premier choice for a wide array of electronic projects. With our commitment to quality and customer satisfaction, you can trust that our Double-Sided Printed Boards will exceed your expectations and contribute to the success of your electronic endeavors.

The Twin Layer PCB, with its double-sided design, is a versatile component used in various electronic applications. The two layers of conductive copper separated by a non-conductive substrate allow for complex circuits to be designed in compact spaces. The white, black, and yellow options for silkscreen color provide clear visibility for labeling and instructions, which is crucial for assembly and maintenance. With a conductor space of 3 mil and a minimum hole diameter of 0.075 mm, these PCBs are designed for precision and high-density component placement, making them ideal for advanced electronic devices.

One of the primary application occasions for the Double Sided PCB is in consumer electronics where space is at a premium. Smartphones, laptops, cameras, and gaming consoles all benefit from the compact yet complex circuitry enabled by a Two-Sided Circuit Board. The extra-long double-sided PCB can be used in larger devices like televisions and home theater systems, where lengthy circuits are necessary to connect various components across the device. Furthermore, the precision of the 3 mil conductor space and 0.075 mm hole diameter supports the intricate designs required by high-performance processors and memory chips found in these products.

In the realm of industrial and commercial electronics, the Twin Layer PCB is indispensable. It is extensively used in control systems for manufacturing machinery, HVAC systems, and automotive electronics. The robust nature of the double-sided design allows for a reliable performance in environments that may expose the boards to higher levels of stress and varying temperatures. The extra-long double-sided PCBs are particularly useful in power distribution systems within industrial settings, where they can span large areas while connecting multiple control points.

Medical equipment manufacturers utilize Two-Sided Circuit Boards for their critical devices. Diagnostic equipment, monitoring systems, and portable medical devices all rely on the compact and reliable design of double-sided PCBs. The high level of precision offered by the 3 mil conductor space and the small hole diameter is paramount in ensuring the reliability and accuracy of medical devices, which can be life-saving.

As for logistics, the shipping options for the Double Sided PCB include an array of express courier services such as DHL, UPS, EMS, TNT, and FedEx. This ensures that the PCBs can be delivered promptly and safely to manufacturers and assemblers around the globe. For larger orders or less urgent deliveries, sea transport is also available, offering a cost-effective solution for bulk shipments.

In summary, the Double Sided PCB is an essential component in a wide range of electronic devices, from personal gadgets to industrial machinery.
