What is a heavy copper double sided pcb circuit board?
Usually the conventional double-sided circuit board generally requires copper thickness of 10 / Z, and multi-layer circuit board is generally the inner layer 0.50 / Z, the outer layer 10 / Z,
There is also the inner layer due to impedance adjustment of the inner layer of copper thickness,so more than 10 / Z of copper thickness we can be regarded as thick copper circuit board
Heavy copper circuit board main control difficulty as below:
Thick copper circuit board is the main control point of its line width from the thicker copper corresponding to the line width from the greater the requirements, or very easy to etch.
In addition, as part of the product requirements of copper plate is not up to the need for board electricity, likely to cause uneven copper surface. So the process requires high, difficult to purchase circuit board.
The benefits of heavy copper double sided circuit board:
The thicker the copper plate, the better the heat dissipation of the product.
The thicker the copper can carry the greater the current.
Copper thicker copper circuit board, the better the stability of the product.
The thicker the circuit board copper, the longer the product life.
Why use heavy copper double sided pcb circuit board?
Due to the need to meet the application of special products and end-product environment
Long-term stability of the operation, so some special industries need to use the circuit board thick copper circuit board technology.
Heavy copper double sided pcb is mainly used in those areas:
Thick copper circuit board is mainly used
In the field of transportation (such as automotive electronics, rail traffic signal control),
medical instruments,
Aerospace industry and industrial control and other fields.
The capacity of double sided PCB manufacturers?
At present the general PCB manufacturer control the thickness of copper are 1.5 or 2 0Z,
As I know ONESEINE TECHNOLOGY company currently controls copper thickness can reach 210 um, that is 60Z.
Heavy copper double sided PCB manufacturing process:
Thick copper main purpose is to ensure that the hole has a enough thick copper coating to ensure that the resistance value within the process requirements. As the insert is a fixed position and to ensure that the connection strength; as surface-mount devices, some holes only as a through-hole, play conductive on both two side .
(A) inspection items
1. The main inspection is metal hole quality , should ensure there are no extra material, burr, black hole, hole, etc in the hole.
2. Check the substrate surface if have dirty and unwanted residue;
3. Check the substrate number, drawing number, process documentation and process description;
4. Find out the location of hanging equipment, installation requirements and plating tank can bear the plating area;
5. Plating area and process parameters must be right, to ensure the stability&feasibility of the plating process parameters.
6. Clean-up and preparation for conductive parts, power on first and so that the solution assumes an activated state
7. Check the touch position and voltage, current fluctuation range.
Here are some key features and advantages of double-sided PCBs:
1,Increased circuit density: Double-sided PCBs have copper traces and components on both sides, which allows for increased circuit density. This means that more components can be placed on the board, making it suitable for complex and compact electronic designs.
2,Enhanced functionality: With components and traces on both sides of the board, double-sided PCBs offer enhanced functionality. They can support more complex circuitry, including the use of through-hole and surface-mount components.
3,Improved signal integrity: The additional copper layer on the reverse side of the board can be utilized for ground planes or power planes. These planes help in reducing electromagnetic interference (EMI) and provide better signal integrity by minimizing noise and crosstalk.
4,Design flexibility: Double-sided PCBs offer greater design flexibility compared to single-sided boards. Components can be placed on both sides, allowing for more efficient use of space. The use of jumper wires or through-hole vias enables connections between the top and bottom layers.
5,Cost-effective: Double-sided PCBs are generally more cost-effective compared to complex multi-layer PCBs. They require fewer manufacturing processes and can be produced using standard fabrication techniques, making them a popular choice for many applications.
What are some common applications that use double-sided PCBs?
1,Consumer Electronics: Double-sided PCBs are extensively employed in consumer electronic devices such as smartphones, tablets, digital cameras, televisions, and audio equipment. The compact size and increased circuit density of double-sided PCBs make them suitable for these portable and space-constrained devices.
2,Industrial Control Systems: Industrial control systems, including automation equipment, robotics, and process control systems, often incorporate double-sided PCBs. These PCBs can accommodate complex control circuitry, interface with sensors and actuators, and provide reliable operation in industrial environments.
3,Automotive Electronics: Double-sided PCBs are widely used in automotive applications, including engine control units (ECUs), dashboard systems, infotainment systems, and electronic modules. They provide the necessary circuitry for various automotive functions while meeting the stringent requirements for reliability and durability.
4,Medical Devices: Many medical devices, such as patient monitoring systems, diagnostic equipment, and medical imaging devices, utilize double-sided PCBs. These PCBs enable the integration of sophisticated electronics, precise sensing, and accurate data processing required for medical applications.
5,Telecommunications: Double-sided PCBs are found in telecommunications equipment, including routers, switches, network cards, and base stations. These PCBs facilitate the complex networking and data processing functionalities necessary for reliable communication systems.
6,Industrial Electronics: Double-sided PCBs are prevalent in a wide range of industrial electronic equipment, including power supplies, control panels, test and measurement instruments, and industrial automation systems. They provide the necessary circuitry for control, monitoring, and communication within industrial environments.
7,LED Lighting: LED lighting systems often utilize double-sided PCBs due to their compact size and ability to support the necessary electronic components for driving and controlling LEDs. These PCBs enable efficient energy conversion, dimming control, and thermal management in LED lighting applications.
