First Article Inspection (FAI) is a systematic sampling inspection procedure that ensures quality. It is a method of conducting inspections strictly in accordance with the requirements of the bill of materials and drawing specifications, in order to identify unknown issues and check the objectivity and accuracy of the parts themselves or in the process, in […]

Choosing the appropriate board is crucial in the PCB manufacturing process. Here are some common PCB boards and their characteristics introduced： 1. **FR-4**: This is the most common type of PCB material, composed of woven glass fibers soaked in epoxy resin. It offers excellent electrical insulation and mechanical strength, making it suitable for a wide range […]

In designing a high-speed analog signal chain, there are many options to consider for printed circuit board (PCB) layout, some more important than others and some dependent on the application. The final answer varies, but in all cases, design engineers should try to eliminate deviations from best practices without obsessing over every detail of layout […]

PCB X ray inspection means using an x ray machine to examine printed circuit boards. X rays are extremely high-frequency and high-energy electromagnetic waves of very short lengths, shorter than those of visible light. These waves can penetrate solid objects. In the world of electronics, manufacturers use the penetrability of x rays to view hidden features of […]

   For the electronics manufacturing industry, PCBA (Printed Circuit Board Assembly) is a necessary link, and its indispensable part is the functional test. Functional test is a very important step to ensure product quality, what is its role? Next, DYC will explore in depth what are the common PCBA functional tests.      PCBA functional […]

PCB color is the pigmented lacquer that manufacturers coat printed circuit boards with. This is usually the color of solder mask. But there’s also another layer called silkscreen. Since these layers are differently colored for trace and other visibility, well start by looking at the options for each. PCB Solder Mask Colors Solder mask is […]

  Resistance refers to the resistance that current encounters in a circuit, or the ability of an object to obstruct the current. The greater the resistance, the greater the resistance to current, and therefore the less current. On the contrary, the smaller the resistance, the less resistance the current is subjected to, and thus the greater the […]

Raspberry Pi is a microcomputer based on ARM architecture, which has won the favor of developers worldwide with its credit card-sized size and powerful features. With the continuous advancement of technology, Raspberry Pi has also continued to release new versions, of which Raspberry Pi 4 and Raspberry Pi 5 are the latest versions of the […]
