What is a heavy copper 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 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.

Customized pcb application:

The application of a customized PCB can vary widely depending on the specific requirements and purpose of the project. Here are some common applications where customized PCBs are used:

1,Consumer Electronics: Custom PCBs are widely used in various consumer electronic devices such as smartphones, tablets, laptops, gaming consoles, wearable devices, audio/video equipment, and home automation systems.

2,Industrial Automation: Customized PCBs find extensive application in industrial automation systems, including programmable logic controllers (PLCs), motor control systems, robotics, process control systems, and instrumentation.

3,Internet of Things (IoT): With the increasing popularity of IoT, customized PCBs play a crucial role in enabling connectivity and smart functionality in IoT devices such as sensors, actuators, gateways, and edge devices.

4,Automotive Electronics: Custom PCBs are used in various automotive applications, including engine control units (ECUs), infotainment systems, advanced driver assistance systems (ADAS), navigation systems, and lighting control modules.

5,Medical Devices: Customized PCBs are essential in medical devices such as patient monitoring systems, diagnostic equipment, imaging systems, implantable devices, and medical wearables.

6,Aerospace and Defense: PCBs designed for aerospace and defense applications require high reliability, ruggedness, and adherence to stringent quality standards. They are used in avionics systems, satellite communication systems, radar systems, and military equipment.

7,Renewable Energy: Customized PCBs are utilized in renewable energy systems such as solar inverters, wind turbine control systems, energy monitoring systems, and battery management systems.

8,Research and Development: Custom PCBs are often used in research and development projects across various domains, including prototyping of new electronic devices, experimental circuits, and proof-of-concept designs.

These are just a few examples, and the applications of customized PCBs are not limited to these areas. PCBs are a fundamental component in almost all electronic devices and systems, and customization allows for optimized performance, integration, and functionality tailored to specific requirements.

To design a customized PCB, you'll need to follow these general steps:

Schematic Design: Create a schematic diagram of your circuit using a PCB design software. This step involves selecting and connecting the desired components, such as microcontrollers, sensors, ICs, resistors, capacitors, etc. If you already have a schematic, you can skip this step.

1,PCB Layout Design: Once the schematic is complete, you'll need to create the physical layout of the PCB. This involves placing the components on the board and routing traces to connect them according to the schematic. Consider factors like component placement for optimal signal flow, power and ground planes, and any mechanical constraints.

2,Component Placement: Carefully place the components on the PCB layout, taking into account factors such as signal integrity, thermal management, and space constraints. Ensure proper clearances between components and adherence to design guidelines for each component.

Routing: Establish connections between components by routing traces on the PCB. Pay attention to signal integrity, impedance control, and avoiding signal crosstalk. Use appropriate trace widths, vias, and layer stack-up to meet your design requirements.

3,Design Rule Check (DRC): Run a design rule check to ensure your PCB layout complies with the fabrication and assembly constraints. This step helps identify errors or violations like clearance violations, unconnected nets, or overlapping components.

Gerber File Generation: Generate the necessary Gerber files from your PCB design software. These files contain the manufacturing information for the PCB, including copper layers, solder mask, silkscreen, drill files, and more.

4,PCB Fabrication: Send the Gerber files to a PCB manufacturer or fabricator to produce the physical PCB. Choose a manufacturer that suits your requirements in terms of quality, cost, and turnaround time. Provide them with any additional specifications such as material type, board thickness, surface finish, and quantity.

5,PCB Assembly: Once you receive the fabricated PCBs, you can proceed with the assembly stage. This involves soldering the components onto the PCB. You can either do it yourself if you have the necessary skills and equipment or outsource it to a PCB assembly service.

It's important to note that designing a customized PCB requires knowledge of electronics, PCB design principles, and proficiency in PCB design software. If you are new to PCB design, it may be helpful to consult with an experienced engineer or work with a professional PCB design service.

If you have any specific requirements or questions during the design process, feel free to ask for assistance.

Why use heavy copper 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 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 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 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.
