It is time to pay attention to some details in the detection of PCB boards, so as to be more prepared to ensure product quality. When testing PCB boards, we should pay attention to the following nine common senses.

Each of these vias needs to be managed in order to use it properly to ensure optimal board performance and error-free manufacturability. Let's take a closer look at the need to manage high-density vias in PCB design and how to do it.

Solder mask (SM) of PCB, solder mask is usually printed after the production of PCB circuit, because the color of ink usually used for circuit boards is green, accounting for more than 90% of the PCB industry, so solder mask is also called green oil.

Five skills that PCB design engineers must master: skilled use of PCB design software, basic English ability, familiarity with devices, reading circuit schematics, understanding key signals, a certain understanding of SI/PI knowledge, and EMC/EMI Knowledge has a deep understanding.

There are many technical specifications related to wiring line width, wiring stackup, schematic diagram and so on in PCB design. Ten small suggestions for PCB component placement can guide electronic beginners to smoothly walk through the initial stage of electronic design.

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.
