Tin spraying: Tin spraying board is a multi-layer (4-46…
The goal of PCB design is to be smaller, faster and cheaper. Because the interconnection point is the weakest link in the circuit chain, the electromagnetic property of the interconnection point is the main problem in RF design. It is necessary to investigate each interconnection point and solve the existing problems. The interconnection of PCB…
In the design of PCB board, with the rapid increase of frequency, there will be many interferences different from that of low frequency PCB board. Moreover, with the increasing frequency and the miniaturization and low cost of PCB board, the contradiction between these interferences is becoming more and more complex. In practical research, we can…
The design of electronic products is a complex and multifaceted process that involves several key stages, from conceptualization to the introduction of the Printed Circuit Board (PCB). Here is an overview of the basic process of electronic product design, with a focus on PCB introduction: 1. Conceptualization: Define the purpose and objectives of the electronic…
In order to meet today’s harsh technical standards, the surface state of printed circuit boards is a key factor. Therefore, metal PCB manufacturers in various countries spend a lot of time and money to adjust the metal surface by deburring, cleaning, brushing and grinding. Among all the materials with surface adjustment, non-woven products have the…

They are widely used in communication equipment, computers, automotive electronics, industrial equipment and various household appliances. Their main functions are supporting circuit elements and interconnection circuit elements. FPC Flexible Printed Circuit Board (FPC) is one…
Multilayer circuit boards are generally defined as high-level multi-layer circuit boards with 10-20 or more layers, which are more difficult to process than traditional multi-layer circuit boards and require high quality and reliability. They are mainly used in communication equipment, high-end servers, medical electronics, aviation, industrial control, military and other fields. In recent years, the…
A “half hole” in the context of printed circuit boards (PCBs) refers to a type of plated through-hole (PTH) that does not extend through the entire thickness of the PCB substrate. Instead, it only goes partially through the board, leaving a hole with a depth that is less than the full thickness of the PCB.…
In terms of medical equipment and technology, the medical industry is growing rapidly. These devices and technologies require printed circuit boards (PCBs) to include complex designs, robust structures and huge power. When medical companies contact PCB manufacturers to meet these requirements, PCB vendors usually recommend two-sided printed circuit boards for medical equipment applications. What makes…

In order to ensure the normal operation of electroplating equipment, the stability in the operation process and the service life of electroplating equipment, the correct maintenance and maintenance of equipment is very important. So, what is the most important thing in maintenance? 1.Classification of equipment…
How does the lamination of multi-layer FPC flexible PCB accomplish? What is the difference between the lamination of multi-layer FPC flexible PCB and traditional rigid PCB? Following is a brief introduction of multi-layer FPC lamination technology. First of all, the multi-layer soft PCB lamination process flow: lamination, die opening, feeding, die closing, pre-pressing, forming, cooling…
Manufacture of flexible printed circuit board The production process of flexible printed circuit boards is basically similar to that of rigid boards. For some operations, the flexibility of laminates requires different devices and completely different treatment methods. Most flexible printed circuit boards adopt a negative approach. However, there are some difficulties in the mechanical processing…
