PCB Engineering

For the production of PCB printed boards, because many designers do not understand the production process of the circuit board, the circuit diagram of the design is only the most basic circuit diagram, and can not be directly used for production. Therefore, it is necessary to modify and edit the line file before actual production. It is not only necessary to produce a film map that can be suitable for the production process of the factory, but also to make corresponding punching data, mold opening data, and other data useful for production. It is directly related to various production projects in the future. These require engineers and technicians to understand the necessary production processes, and at the same time master the relevant software production, including common circuit design software such as: Protel, Pads2000, Autocad, etc., should be familiar with the necessary CAM software such as: View2001, CAM350; GCCAM Etc., CAM should include PCB design inputs, which can edit, correct, repair, and imprint circuit graphics, use disk as the dielectric material, and output automated data for ray mapping, drilling, and inspection.

​14 most important features of high reliability PCB

At first glance, the PCB is similar in appearance regardless of its inherent quality. It is through the surface that we see the differences that are critical to the durability and functionality of the PCB throughout its lifetime.

PCB Classification and Characteristics

It can be classified according to PCB use, substrate type, structure, etc., and is generally divided by PCB structure.

EMC: PCB Engineer Considerations and Grounding Tips

Basic grounding method: There are three basic grounding methods in electronic equipment: single-point grounding, multi-point grounding, and floating ground.

PCB copper experience

The so-called copper coating is to use the unused space on the PCB as the reference surface, and then fill it with solid copper. These copper areas are also called copper filling.

Overview of High Precision Technology for PCBs

The high precision of printed circuits refers to the use of fine line width/pitch, micro holes, narrow ring width (or no ring width), and buried, blind holes and other technologies to achieve high density. The high precision means that the result of "fine, small, narrow, thin" will inevitably bring high precision. Take the line width as an example: O.20mm line width, and O.16-0.24mm is qualified according to the regulations. The error is (O.20 soil 0.04) mm; and the line width of O.10mm, the same error is (0.10±O.02) mm, obviously the accuracy of the latter is doubled, and so on is not difficult to understand. Therefore, the high precision requirements are not discussed separately. But it is a prominent problem in production technology.

The below describes several EDA software commonly used in circuit design. There are many EDA softwares in this industry, such as transformer design, electrical design, integrated circuit design, etc., as well as a variety of microcontrollers. Simulation software.

POWERPCB tips

PowerPCB enables users to achieve high-quality design and vividly reflects all aspects of the electronics design industry. Its constraint-driven design approach reduces product completion time. You can define safety spacing, routing rules, and design rules for high-speed circuits for each signal, and apply these plans hierarchically to the board, to each layer, to each type of network, to each network, to each group. On the network, each pin is placed to ensure the correctness of the layout design. It includes a wide range of features including clustering tools, dynamic routing editing, dynamic electrical performance checks, automatic dimensioning and powerful CAM output capabilities. It also has the ability to integrate third-party software tools such as the SPECCTRA router.
