Explore the latest innovations in electronic board assembly techniques and trends, highlighting advancements in automation, materials, and process efficiency that are shaping the future of the electronics manufacturing industry.
Differential transmission is a signal transmission technology. Different from the traditional method of one signal line and one ground line, differential transmission transmits signals on both lines. The amplitudes of the two signals are equal, the phases are 180 degrees apart, and the polarities are opposite. The signal transmitted on these two lines is a…
Explore the world of electronics assembly services in this comprehensive guide. Learn about various techniques, benefits, and best practices to enhance production efficiency and quality in your electronic manufacturing processes.
Introducing three special PCB routing techniques. The routing of PCB LAYOUT will be explained from three aspects: right-angle routing, differential routing, and serpentine routing: 1.Right-angle routing (three aspects) The impact of right-angle routing on signals is mainly reflected in three aspects: first, the corner can be equivalent to the capacitive load on the transmission line,…
Speaking of copying boards, you may think that there is no technical content, but those who have really copied should have a deep understanding that it is not that simple. PCB copying has no software and can only be measured and drawn with a caliper, which is slow and has poor accuracy. It is very…
1.The FR-4 we often choose is not the name of a material The “FR-4” we often refer to is a code for a flame-resistant material grade. It means that the resin material must be able to extinguish itself after burning. It is not a material name, but a material grade. Therefore, there are many types…
In electronic devices, from small electronic watches and calculators to large computers, general electronic equipment, and military weapon systems, as long as there are electronic components, PCBs are used for interconnection between them. Printed Circuit Board (PCB), commonly known as PCB, is one of the important components of electronic products. The main function of PCB…
Take LVDS signal as an example to explain the common optimization methods for high-speed signals in PCB design: LVDS (Low Voltage Differential Signaling) is a low-swing differential signal technology that enables signals to be transmitted at a rate of several hundred Mbps on differential PCB line pairs or balanced cables. Its low voltage amplitude and…
Perhaps we will wonder, the substrate of the circuit board has copper foil only on two sides, and the middle is an insulating layer, so do they not need to be connected between the two sides or multiple layers of the circuit board? How can the lines on both sides be connected together to allow…
This article explores the latest advancements in PCB manufacturing techniques and technologies, highlighting innovations that enhance efficiency, precision, and sustainability in the production process for printed circuit boards.
1 Surface tension The cohesive force of tin-lead solder is even greater than that of water, making the solder spherical to minimize its surface area (under the same volume, the sphere has the smallest surface area compared to other geometric shapes to meet the requirements of the lowest energy state). The effect of flux is…
Blistering is one of the more common quality defects in the production process of circuit boards. The complexity of the production process and process maintenance of circuit boards, especially in chemical wet treatment, makes it difficult to prevent blistering defects on the board surface. Based on many years of actual production experience and service experience,…
The main factor that determines the quality and positioning of a board is the surface treatment process. For example, OSP tin spraying, gold plating, and immersion gold. Relatively speaking, immersion gold is for high-end boards. Due to its good quality, immersion gold is also relatively costly. Therefore, many customers choose the most commonly used tin…
The solder mask is the soldermask, which refers to the part of the printed circuit board that is to be painted with green oil. In fact, this solder mask uses a negative output, so after the shape of the solder mask is mapped to the board, it is not the green oil solder mask that…
This article explores strategies to enhance efficiency and quality in PCB assembly and manufacturing. It provides insights into best practices, innovative technologies, and process improvements to streamline production and ensure high standards.
