The development trend of the electronics industry has higher and higher requirements for the assembly process of PCBA, and the reliability and quality of electronic products are mainly determined by the quality level of PCBA. In the process practice and the failure analysis of PCBA, we found that the residue on PCBA ha...

PCB Market Trends 1. From the perspective of segmented products: HDI and FPCB demand is less than expected, but high-level digital boards and high-end packaging substrates are in strong demand; 2. From the perspective of product application: the demand for mobile phones and automotive electronics is gradually rising, a...

No matter what type of printed circuit board needs to be built or what type of equipment it is applied to, the PCB must work normally. It is the key to the performance of many products, and failures can cause serious consequences. Testing the PCB during the design, manufacturing, and assembly process is essential to en...

Introduction Quite often, when we develop our PCBs, we only care about the circuit components that are essential for our projects, such as microcontrollers, LDOs, battery managers, LEDs, sensors, etc. Forgetting about the protection circuits which are very important to ensure the correct functioning of our project. Esp...

If there is a way to ensure that the product is reliable, it is to ensure the predictability of its PCB, which is an important part of the product. In fact, PCB is the core component in almost all electronic products (from phones to computer systems) today. From automobiles to national defense, from aviation to technol...

Printed Circuit Boards (PCBs) are made of non-conductive substrates coated in conductive laminate copper sheets. The copper serves as the base material from which pathways connecting electronic components are carved, and the non-conductive substrate anchors the whole device. As a unit, a PCB board is relatively tough a...

There are four main types of plating methods in PCB (Printed Circuit Board) production: finger-plated plating, through-hole plating, reel linkage selective plating and brushing plating. Here's a brief introduction: 1. Finger-plated plating Rare metals need to be plated on the board edge connectors, board edge joint...

The PCBs can be single-layer (one copper layer), double-layer (two copper layers) or multilayer. The conductors on different layers are connected with plated through holes called vias. Advanced PCBs may contain components embedded in the substrate-capacitors, resistors or active devices. Have you ever thought about mak...

In recent years, with the vigorous development of communications, electronics, automotive, medical and other industries, it has strongly promoted the development of the PCB industry. In the PCB production process, a large amount of waste gas will be generated, which needs to be effectively treated, otherwise it will ca...

When PCBs are mass manufactured, a dividing line will be formed between the two single boards in a "V" shape, which is convenient for breaking and separating after soldering. We call this V-cut. Let’s dive into this V-cut design today. Purpose of V-cut The main purpose of designing V-cut is to facilitate the...

Disassembling an electronic product, we will find that there are usually several PCBs inside, and the PCB colors are various: green, blue, red, white, black, etc., what is the difference between these different colors? Today let’s learn about PCB inks. The color of PCB is mainly the color of solder mask ink. Green, bl...

Printed circuit boards are widely used in various electronics and technologies, making them very valuable devices. Whether it is a mobile phone, a computer or a complex machine, you will find that the PCB is responsible for the function of the device. If the PCB has defects or manufacturing problems, it may cause the f...
