PCB design is based on the functions required by customers, and PCB design engineers design PCB schematics to achieve the tasks required by customers.
The main work of PCB design is PCB schematic design, which must consider the arrangement of external connections and the shape and structure of the product. In addition,
PCB board design must also consider the optimal shape of electronic components inside the PCB, the optimal layout of circuit connections and PCB vias, electromagnetic protection factors, and heat dissipation.
Excellent printed circuit board design can save PCB manufacturing costs and improve the performance of electronic products.

PCB design service is one of the ways ZBPCB helps customers enter the market faster, because ZBPCB’s PCB board design team has rich practical experience in PCB design,
Which can improve performance and manufacturability. ZBPCB focuses on communication network PCB design, industrial control, medical, aerospace; testing ATE IC,

What is PCB Design?

1. If you simply have an idea or concept, or have completed a schematic, we can convert it into a design document, followed by PCB manufacturing, PCB assembly and testing. With over 15 years of experience in printed circuit board manufacturing and bodywork, we can ensure that the design is fully compliant with manufacturing requirements.

2. ZBPCB’s PCB design team will work with you throughout the product development process to ensure that every aspect of the design is technically checked before first production.

3. Once the PCB design is signed for production, ZBPCB’s skilled development production team is on call to build high-quality PCBA prototypes for initial testing and purposes.

4. Through machine and hand placement, parts can be mounted on PCBs in as little as 48 hours, with full inspection as standard, and additional testing as required.

5. ZBPCB aims to make the process as simple as possible by providing all of these services, saving you valuable time and allowing you to focus on bringing your product to market.

PCB Design software

1. The main ones used in China are Protel, PROTEL 99SE, PROTEL DXP, and Altium. This is a newer software developed by a company; the current version is Altium designer 15, which is a relatively simple and casual design, but it is not very useful for complex PCB software.

2. Cadence SPB software cadence SPB This is cadence software, and the current version is cadence SPB 16.5; OrCAD schematic design is an international standard; PCB design and simulation are more comprehensive, more complex than Protel, mainly because the requirements and settings are more complex; but it provides convenience for design, so the design is more efficient and the function is more powerful than Protel.

3. bordstationg, ee, including word station of mentor company. Since word station is only applicable to UNIX system and not designed for PC, few people use it; EE mentor The current version is EE mentor 7.9 and SPB cadence, which are PCB design software of the same level. Some places are worse than SPB cadence, and the strengths are line setting and flying line, which is called the king of flying line.

4. Eagle PCB design for easy layout is the most widely used PCB design software in Europe. The above PCB design software is widely used. Cadence SPB and mentor are the well-deserved kings. If you are a beginner in PCB design, I think SPB cadence is better. It can cultivate good design habits of designers and ensure good design quality.

How To Design PCB Board? Four Stages of PCB Design

1. Concept Refinement. –We summarize the project goals and create documents to specify the technical scope of the project.

2. Feasibility Study. –We conduct a study to check if the project can be completed within the client’s budget. The agreed tasks will be developed. A draft report is submitted to the client for feedback.

3. Hardware and Software Design. –We design the electronic circuit and make schematics, create bench prototypes. The software code is edited.

4. Testing and Trials. –When the software and hardware design is completed, we can start rigorous bench testing. We continue until the design meets the project specifications.

Pre-preparation

Including preparing component libraries and schematics. Before PCB design, you must first prepare the SCH schematic component library and PCB component package library.

The PCB component package library is best established by engineers based on the standard size data of the selected device. In principle,

The PC component package library is established first, and then the schematic SCH component library is established.

The requirements for the PCB component package library are high, which directly affects the installation of the PCB.
The schematic requirements for the SCH component library are relatively vague, but attention should be paid to the definition of the pin attributes and the correspondence with the
PCB component package library.

PCB Structure Design

According to the size of the circuit board and the mechanical layout, draw the PCB frame in the PCB board design environment, and place the required connectors, buttons/switches, screw holes, mounting holes, etc. according to the layout requirements. Fully consider and determine the wiring area and non-wiring area (how much area around the screw hole is the non-wiring area)

PCB design – PCB design

Make a PCB schematic according to the required product functions, use the PCB schematic design tool to draw the schematic, and generate the corresponding network table. Of course, in some special cases, such as when the printed circuit board is relatively simple and there is a network table, you can directly enter the PCB design system without going through the schematic design. In the PCB design system, you can directly participate in the package and manually generate the network table.

You can also manually set the network table, define the pads that are not on the PCB schematic as fixed pins of some components to the network connected to them, which can be defined as having no physical connection, and change the pin names of some devices in the schematic that are inconsistent with the names in the PCB package library to be consistent with the names in the PCB library, especially diodes and transistors.

PCB

Layout On the PCB, there are some key components, core components, components that are susceptible to interference, high-voltage components, components with high heat generation, and some heterogeneous components. The positions of these special components must be analyzed, and the layout of the PCB must meet the requirements of circuit functions and PCB manufacturing and PCBA manufacturing. Improper placement of these components will cause circuit compatibility problems or signal integrity problems, leading to PCB design failure.

When placing special components in PCB design, the size of the PCB must be considered first. ZBPCB believes that if the PCB size is too large, the printed circuit will be long, the impedance will increase, the dry resistance will decrease, and the cost will increase; if it is too small, the heat dissipation will be poor, and the adjacent circuits will be susceptible to interference. After determining the PCB size, determine the orientation of the special components. Finally, the PCB layout of all circuit components is carried out according to the functional unit.

PCB production example – PCB assembly – PCBA

Circuit board This is a process from PCB sample to PCB design function. This process requires a professional production team to complete. For example, some process errors will also lead to product development failure, so this is a very important process.

PCB Design Process

In electronic design and development, PCB design and component selection need to be focused on.

1. PCB design must consider issues such as wiring, SMT difficulty, separation of analog circuits and digital circuits, and electromagnetic interference between components and circuits.
Pay special attention to interference issues, because such problems are sometimes hidden problems and may appear at some point. If they appear after mass production, it will be embarrassing.

2. Due to the problem of component selection, side door components should be avoided when selecting electronic components,
Because such components may be shut down at any time or difficult to be compatible with other components.
Sometimes replacing a component will cause serious problems due to incompatible pins or pin units. For products,
Using mature and stable components can not only improve the stability of the product, but sometimes also reduce the cost of the product.

After designing the PCB board, you can run the PCB sample. After the PCB sample is completed, you can burn the firmware to test and optimize the PCBA.
