As components also became smaller and the need for more adaptability of a board is smaller spaces, single or double-layered designs were not capable of providing expected effectiveness, giving birth to multilayer design, which considers boards with three or more layers, including, for example, 6, 10, 16 or even 20 layer PCB. In this article, we will explore and dig more on this last option and review some of its characteristics and applications.
A solder joint is a resulting connection between the two surfaces.
It is one of the most important parts in electronics. It connects two or more pieces of electronic equipment and makes sure that they work together well. Soldering joints are used in many different types of products, such as computers, cell phones, and even electric vehicles.
FPC is the abbreviation of Flexible Printed Circuit, also known as flexible printed circuit board, which is a printed circuit board made of flexible insulating substrate. As an important category of PCB, it has the advantages of high wiring density, thin thickness, light weight, and good bendability. Compared with other types of circuit boards, it is more in line with the development trend of intelligent and portable electronic products in the downstream industry. It is widely used in modern electronic products. FPC can be divided into four types: single-sided flexible board, double-sided flexible board, multi-layer flexible board and rigid-flexible board.
Solder beading was found on boards that had been reflowed. It is a large solder ball embedded in a pool of flux that is positioned next to a discrete components. These components have a very low ground clearance, such as chip resistors and capacitors, thin small outline packages (TSOPs), small outline transistors (SOTs), D-PAK transistors, and resistor assemblies.
As electronic products update and iterate faster and faster, they continue to develop in the direction of high density, miniaturization, and high reliability. In order to save assembly space and reduce costs, related accessories are also constantly being upgraded, such as FPC vs FFC, which are widely used in our electrical equipment.
Both FPC vs FFC are flat and can be bent at will, so do these two similar products belong to the same category? What are their differences and similarities between FPC vs FFC?
The rise of emerging industries, charging of electric vehicles, and widespread use of drones have further expanded the use of conformal coatings. At present, the application of conformal coatings in PCBA has become a mainstream trend.Therefore, this article will introduce about PCB conformal coating.
Wave soldering is to make the soldering surface of the PCB board directly contact with high-temperature liquid tin to achieve the purpose of welding. High-temperature liquid tin maintains a beveled surface, and the liquid tin is formed a wave-like phenomenon by a special device , so it is called “wave soldering”, and its main material is a solder bar.This article will introduce information about wave soldering in PCBA process.
Soldering is one of the most important processes in PCBA processing. On printed circuit boards, electrical connections to all components are made via PCB pads. The PCB pads are a very critical part of the PCB that determines where components are soldered on the PCB.The size, shape, and position of pads in a PCB directly depend on the manufacturing quality of the board. Today we will take a look at the PCB pad in SMT soldering.
Current PCB substrates can be divided into three categories: ordinary substrates, metal substrates and ceramic substrates, which can meet different needs and purposes. Today this article will mainly introduce the definition, type, material, application, structure and production process of MCPCB- metal core PCB.
Vietnam is one of the world’s major electronics exporters, and the electronics industry plays an important role in the country’s economy. Vietnam’s electronics industry revenue is expected to reach US$8.65 billion. In this article, we will introduce 8 Vietnam PCB manufacturers .
