1.The FR-4 we often choose is not the name of a material The “FR-4” we often refer to is a code for a flame-resistant material grade. It means that the resin material must be able to extinguish itself after burning. It is not a material name, but a material grade. Therefore, there are many types…
Current circuit boards are mainly composed of the following: Features of integrated circuits” ]! q’ L$ O% h3 D d. q/ ? Integrated circuits have the advantages of small size, light weight, fewer lead wires and welding points, long life, high reliability, good performance, etc., and low cost, which is convenient for large-scale production. It…
1.How to choose PCB proofing material? The selection of PCB material must strike a balance between meeting design requirements and mass production and cost. Usually, when designing very high-speed PCB boards, the material problem is more important. For example, the dielectric loss of the commonly used FR-4 material at a frequency of several GHz will…
1.PCB surface treatment: Anti-oxidation, tin spraying, lead-free tin spraying, immersion gold, immersion tin, immersion silver, hard gold plating, full-board gold plating, gold finger, nickel-palladium gold OSP: low cost, good solderability, harsh storage conditions, short time, environmentally friendly process, good welding, flatness. Tin spraying: Tin spraying boards are generally multi-layer (4-46 layers) high-precision PCB samples, which…

There is a very common process in the surface treatment of circuit boards, called gold-immersion. The purpose of the gold-immersion process is to deposit a nickel-gold plating with stable color, good brightness, flat plating and good solderability on the surface of the printed circuits on the PCB. In simple terms, gold-immersion is a chemical deposition…

1.Appearance and electrical performance requirements The most intuitive impact of contaminants on PCBA is the appearance of PCBA. If placed or used in a high temperature and humid environment, there may be moisture absorption and residue whitening. Due to the widespread use of leadless chips, micro BGAs, chip-scale packages (CSPs), and 0201 components in components,…
With the rapid development of high-frequency and high-speed electronic products, signal transmission is more prone to signal integrity problems such as reflection and crosstalk. The higher the frequency and the faster the transmission rate, the more serious the signal loss. How to reduce the loss of the signal during transmission and ensure signal integrity is…
Electroplated sealing is a commonly used printed circuit board manufacturing process for filling and sealing vias (through holes) to enhance conductivity and protection. In the printed circuit board manufacturing process, vias are channels used to connect different circuit layers. The purpose of electroplated sealing is to form a layer of metal or conductive material deposition…
As electronic devices develop towards higher performance and smaller size, their requirements for PCB precision and performance are also getting higher and higher. High-layer PCBs can provide more routing layers, making circuit design more complex and dense, thereby meeting the needs of high-frequency and high-speed transmission. In addition, high-layer PCBs can also achieve better signal…
