Outsourcing design process of circuit board

Circuit board is in English, literally translated as “printed circuit board”, as well as circuit board, PCB, PCB, etc., which is an important part of electronic equipment in the modern technology era. The appearance of circuit board provides various functions for electronic products and realizes the integration of circuits. It mainly consists of pads, holes, mounting holes, wires, components, connectors, fillers, electrical boundaries, etc. Its main functions are:
Solder joint: a metal hole used to solder the pins of a component.
Through hole: It is divided into metal through hole and nonmetal through hole. Metal through hole is used to connect the component pins between layers.
Mounting hole: fixed circuit board.
Wire: electronic mesh copper film, used to connect the pins of components.
Plug: A component connected to a circuit board.
Filling: grounding mesh copper, which can effectively reduce the resistance.
Electrical limit: determines the size of the circuit board. On all circuit boards, no component will exceed this range.
Class of circuit board:
According to the number of layers, circuit boards can be divided into three categories: single-sided, double-sided and multi-layered. On the most basic printed circuit board, the components are concentrated on one side and the wires are concentrated on the other side. Because the wire has only one side, it is called a single-sided circuit board. Double board is an extension of single board. If single-layer wiring can’t meet the requirements of electronic equipment, double-layer board can be used. Both sides have copper plating and wiring, and the wires between the two layers can be conducted through perforations, thus forming the required network. Multilayer is a printed board with three or more conductive patterns, and the insulating materials between them are stacked at intervals, and the conductive patterns between them are connected to each other as required. Multi-layer circuit board is the inevitable trend of electronic information technology towards high speed, multifunction, large capacity, small size, light weight and light weight.
The basic design procedure of circuit board can be divided into the following steps:
1. Circuit diagram of circuit board outsourcing design.
(1) The system mainly uses Protel DXP’s circuit diagram editor to draw the circuit diagram and produce a complete set of online reports.
(2) Design PCB and generate PCB report. For example, generate various reports, such as pin reports, circuit board information reports, network status reports, etc., and finally print out the circuit diagram.
2. A design method of circuit diagram:
(1) Set the size and layout of the circuit board, take out the required parts from the component library and put them on the working plane;
(2) Connect the components according to the design requirements, and adjust the wired components;
(3) An EMC design for cable construction.
(4) EMC design of printed circuit board.
(5) Design of EMC principle device.
(6) Production and functional debugging of circuit boards.
There are many links in the outsourcing design of circuit boards. If the defects can’t be found in the design process, everything will be lost. To solve problems in PCB design, standardize design standards, improve design efficiency, promote product development cycle and reduce production costs, it is a necessary desktop tool for PCB engineers, hardware engineers, PCB factories, SMT factories and PCB traders. Now, more than 200,000 engineers are using the software.
