The purpose of the test point is to test whether the components on the circuit board meet the specifications and solderability. For example, if you want to check whether there is any problem with the resistance of a circuit board, the easiest way is to use a multimeter to measure its two ends. Just know.

A systematic approach to writing a PCB Design Rule Checker (DRC). Once the PCB design is obtained with the schematic generation tool, DRC can be run to find any design rule violations.

The number of layers of the PCB depends on the complexity of the circuit board. From the perspective of the PCB processing process, a multi-layer PCB is manufactured by stacking and laminating multiple "double-sided PCB".

When designing a PCB, we usually rely on previous experience and tips that we would normally find online. Every PCB design can be optimized for a specific application, and usually, its design rules apply only to the target application.

A high-speed PCB design is any design where the integrity of the signal begins to be affected by the physical properties of the PCB. when you start designing your board and you run into troubles like delay, crosstalk, reflections or emissions, you're entering the realm of high-speed PCB design.

A PCB schematic is a simple two-dimensional circuit design showing the function and connectivity between different components. The PCB design is a three-dimensional layout, and the position of the components is marked after ensuring the normal operation of the circuit.

The PCB screen printing process includes: principle, working conditions, screen preparation, screen production, ink mixing, use of scraper, screen positioning method, incoming board inspection, board printing, screen printing, pre-baking, exposure, development, and curing.

Modern PCBA electronic assembly is a relatively complex process. In the process of production, PCB defects are caused by factors of PCB substrate and PCB board processing.

The screen printing layer of the PCB board is the text layer. Its function is to facilitate the installation and maintenance of the circuit, and print the required logo patterns and text codes on the upper and lower surfaces of the PCB board, such as component labels and nominal values. Profile shape and manufacturer logo, production date, etc.

PCB is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made using electronic printing, it is called a "printed" circuit board.

PCB have developed from single layer to double-sided, multi-layer and flexible, and still maintain their respective development trends. How is the schematic diagram of the PCB circuit board designed? Read the following seven steps to understand.

Via is one of the important components of multi-layer PCB, and the cost of drilling usually accounts for 30% to 40% of the cost of PCB fabrication. Simply put, every hole on a PCB can be called a via.

We provide you with effective techniques to improve the PCB design layout rate and design efficiency, which not only saves the project development cycle for customers, but also maximizes the quality of the design finished products.

The solder mask process in PCB is to cover the printed board with solder mask after screen printing with a photographic plate to cover the pads on the printed board, so that it will not be exposed to ultraviolet rays during exposure, and the solder mask protective layer After UV irradiation, it is more firmly attached to the surface of the printed board, and the pads are not exposed to UV light, which can expose the copper pads for lead and tin during the hot air leveling process.

In order to properly understand the PCB manufacturing steps. Hopefully it provides circuit designers and newcomers to the PCB industry with a clear view on how to make printed circuit boards and avoid making those unnecessary mistakes.

PCB can be divided into single-sided, double-sided and multi-layered boards from the structure, and the design focus of different boards is also different.
