What is Lamination Process in PCB Fabrication?

PCBs are called “laminated sandwiches” simply because they comprise multiple layers bonded together with high temperatures and pressure. It is an accurate definition of “lamination” and also a vital step of PCB fabrication. If you want to advance in your knowledge of printed circuit board fabrication – manage this post to the end. Let’s deepen […]

Several Points of RF Circuit Board Design

Although there are many theoretical uncertainties in radio frequency (RF) circuit board design, there are many RF circuit board design rules. However, when it comes to the actual design, the real trick is how to compromise these laws when they cannot be implemented due to various constraints. This article will focus on various issues related […]

What is V Groove PCB?

The V groove PCB results after the splitting of circuit boards. This requires the cutting of the circuit board and leaving a little material to help hold these boards. The final stages involved in the production are profiling the v groove PCB and cutting them from the manufacturing panel. This is either done by routing […]

Common Rules for PCB Design and Routing

A large part of the work of signal integrity is based on the setting of PCB routing rules and routing optimization. The simulation work or post-imitation work is based on the fact that the PCB design has been finalized, that is to say, the related risks of the link have been fixed. Therefore, setting rules […]

Why FR4 Material is Commonly used in PCB Fabrication?

FR4 material is the most common grade dielectric material that is used in the fabrication of circuit boards. This material is incorporated in single-sided, double-sided, and multi-layered boards. Here are a few qualities of FR4 materials that make them popular: Wide range of operating temperatures (50°C to 115°C) Higher Tg value (about 180°C) Offers decent mechanical […]

PCB Lead-free regulations

Until recently, lead was almost ubiquitous in the construction of printed circuit boards (PCBs). Due to its melting point and ability to form strong bonds between surfaces, a eutectic lead-tin alloy proved highly effective as a solder material. However, as electronic waste volumes increased, the use of lead in circuit boards came under scrutiny in […]

Comparison of Dry Film and Wet Film for PCB Processing

The dry film is easy to operate, especially using an automatic film laminating machine, which can be mass-produced. The wet film is cheap, but it cannot be used on automatic lines. The wet film is theoretically good for thin lines, but the wet film also has many other problems. In general, the dry film is […]

PCB Short Circuit Inspection Method

1. If it is manual welding, it is necessary to develop a good habit. First, visually check the PCB board before welding, and use a multimeter to check whether the key circuits (especially the power supply and ground) are short-circuited. Use a multimeter to test whether the power supply and the ground are short-circuited. In addition, do […]

Electrical Rules Should Be Paid Attention To In PCB Design

1. Treatment of power supply and ground wire Even if the wiring in the entire PCB board is completed very well, the interference caused by the improper consideration of the power supply and the ground wire will reduce the performance of the product, and sometimes even affect the success rate of the product. Therefore, the […]

Importance of Welding of PCB Design

Some people say that the most important thing in hardware development is principle design and PCB design, while others say that the most important thing in hardware development is performance. However, few people care about the soldering process before the birth of the hardware product, that is, the process of device assembly. The result is […]
