The countless small holes we see on PCBs are technically called vias, which are actually the only way to change layers of wiring. Figure 1 below shows the three typical types of vias on our PCB, namely through hole vias, blind vias, and buried vias. Most of the situations we usually encounter are pure through-hole […]
Conductive hole Via hole is also known as conduction hole. In order to meet customer requirements, the circuit board via hole must be plugged. After a lot of practice, the traditional aluminum sheet plugging process is changed, and the circuit board surface is completed with white mesh. hole. The production is stable and the quality […]
With the rapid improvement of signal transmission speed and the wide application of high-frequency circuits, the circuit performance provided by PCB must be able to prevent signal reflection during transmission, keep the signal intact, reduce transmission loss, and play a role in matching impedance. In order to get a complete, reliable, accurate, interference-free, and low-noise […]
Mounting holes in a PCB are an important element in electronic design. Every PCB designer will go to understand the purpose of PCB mounting holes and the basic design. And, when the installation hole is connected with the ground, it can save some unnecessary troubles after installation. How to use PCB holes to reduce EMI? […]
The process of printing a layer of blue glue on the PCB by screen printing or aluminum screen printing Peelable Solder Mask is a process that uses screen printing or aluminum screen printing to print a layer of blue glue on some parts of the PCB, and after curing, it acts as a protection and […]
Introduction to multilayer circuit boards The double-sided board is a medium layer in the middle, and both sides are wiring layers. A multi-layer board is a multi-layer wiring layer. There is a dielectric layer between every two layers. The dielectric layer can be made very thin. A multilayer circuit board has at least three conductive […]
This first-order, second-order is to talk about the HDI manufacturing process of this PCB processing. What is HDI? HDI: short for high Density interconnection, high-density interconnection, non-mechanical drilling, micro-blind hole ring below 6mil, wiring width/line gap between inner and outer layers below 4mil, pad diameter not more than 0.35mm Laminate manufacturing method is called HDI […]
The thickness of the PCB board has a huge influence on the designer during the design process of the PCB board. Consistency has an intrinsic gravity. If you ignore it, the PCB board may not work or may cause damage or sparks, which may also cause harm to components connected to the board. Since there […]
Vias, holes on the circuit board, connect the lines between different layers, and change the circuit board from a planar structure to a three-dimensional structure.It is too difficult for single-layer lines to not cross, and double-layer or more layers must be connected through vias. Through the copper on the hole wall, the circuit copper wires […]
The sensitivity of electronic equipment is getting higher and higher, which requires the anti-interference ability of the equipment to become stronger and stronger, so PCB design has become more difficult. How to improve the anti-interference ability of PCB has become one of the key issues that many engineers pay attention to. This article will introduce […]
Technology of Via and Back Drilling in PCB Production Friends who have done PCB design know that the design of PCB vias is actually very particular, so what are the technologies of PCB State Control? Today, I will share with you the technical knowledge of vias and back drilling in PCB. Via design in high-speed […]
What is a via Vias, holes on the circuit board, connect the lines between different layers, and change the circuit board from a planar structure to a three-dimensional structure. It is too difficult to avoid crossing of single-layer lines, and double-layer or more lines must be connected through vias. Through the copper on the hole […]
