Electroplating can be divided into hard gold and soft gold. Hard gold electroplating is an alloy, so its hardness is relatively hard. It is suitable for use in places requiring force and friction. It is generally used as the edge contact point of PCB ( commonly known as golden finger ). Soft gold, On the…
The purpose of hard gold plating PCB adhesive tape is to expose only the part of the board to be plated with hard gold, and to cover the rest with adhesive tape to prevent plating. Tape sticking is a delicate work. It is not allowed to stick the golden finger with tape, and it is…
Aluminum is a passive metal. Like titanium, tantalum, niobium and other metals, passive oxide film on the surface is an important factor to provide protection. Therefore, anodic oxidation is a very effective means of metal protection. Anodic oxidation treatment for aluminium and its alloys is an “wanneng” way to improve the protective and decorative characteristics…
The introduction of new line-to-board plug connectors and board-to-board connectors further enriches the series of non-polar sockets and socket connectors. The connector is specially designed for connecting aluminum printed circuit boards, which is mainly used for lighting control and LED lighting module applications, making its assembly faster and easier. The new plug connector is made…

Custom circuit board China customized circuit board Circuit board design is as its name implies: The design of circuit boards is done according to the requirements. Simply speaking, the pcb Copy Board is template custom circuit board china according to the template provided. Many people think it's the same, but it's still different. PCB design…
Recently, the industry has developed a new green manufacturing technology of double-sided flexible PCB, and human technology has made further progress, which is nearer to the foldable screens. This achievement will be presented at China international industrial exposition. This kind of printed circuit board with light weight, thin thickness, softness and flexibly “like printed newspaper”…
PCB ENIG (Electroless Nickel Immersion Gold) and PCB gold plating are two common surface finish techniques used in the fabrication of printed circuit boards (PCBs). Here are the key differences between ENIG and gold plating: ENIG (Electroless Nickel Immersion Gold): Composition: ENIG involves a two-step process. First, a thin layer of nickel is deposited onto…
First, Surface Treatment of PCB Board Anti-oxidation, tin spraying, lead-free tin spraying, gold precipitation, tin precipitation, silver precipitation, hard gold plating, full plate gold plating, gold finger, nickel palladium gold OSP: lower cost, good solderability, harsh storage conditions, short time, environmental protection technology, good soldering, smooth. 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…
1. Overview of FPC flexible printed circuit board Printed circuit boards (PCBs) are the basic products of the electronic industry. 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.…
