With the gradual development of short, small, light and thin electronic products, the advantages of flexible circuit boards are becoming more and more obvious, and the market demand is also increasing. Gold plating, tin plating, OSP, etc., then immersion gold and gold plating are both gold, what is the difference between them? What are the […]
1.Introduction to FPC FPC: English spelling Flexible Printed Circuit, which means flexible printed circuit board, referred to as soft board. It is made by using photo-imaging pattern transfer and etching process on the surface of a flexible substrate to make conductor circuit patterns. The surface and inner layers of double-sided and multi-layer circuit boards are […]
Do you know “why the PCB must be baked before SMT can pass through the reflow oven after the expiration date exceeds the shelf life”? The main purpose of PCB baking is to dehumidify and dehumidify, and to remove the moisture contained in the PCB or absorbed from the outside world, because some materials used […]
We live in a world driven by technology and use them in nearly every aspect of our daily lives. We tend to depend on smart electronic devices to make our lives easier, organised and better connected. Needless to say, all these electronic devices are designed over a Printed Circuit Board (PCB). Printed circuit boards were […]
Both rigid and flexible printed circuit boards (PCBs) are used to connect electronic components in various consumer and non-consumer devices. As the name suggests, a rigid PCB is a circuit board built on a rigid base layer that cannot be bent, while a flexible PCB (also known as a flex circuit) is built on a […]
1. Manual visual test Manual visual testing is to confirm the placement of components on the PCB through human vision and comparison. This technology is one of the most widely used online testing methods. But with the increase in output and the shrinking of circuit boards and components, this method is becoming less and less […]
1.PCB board color Even for some people who don’t know what a PCB is, they generally know what a PCB looks like. They at least seem to have a traditional style, which is its green color. This green is actually the transparent color of the solder mask glass paint. Although the name of the solder […]
With the continuous improvement of human requirements for the living environment, the environmental problems involved in the current PCB production process are particularly prominent. The topic of lead and bromine is currently the hottest topic; lead-free and halogen-free will affect PCB development in many ways. Although the changes in the surface finish process of PCBs […]
In a general sense, transmission lines are electrical transmission lines connecting the power supply of kilos of volts from the thermal generating station to distributors and consumers. However, there also exist transmission lines, which carry electricity of lower voltage and higher frequencies. PCB Transmission Lines: A PCB transmission line connects moving signals from their transmitters […]
What is a Regid and flexible board The birth and development of FPC and PCB gave birth to a new product of Regid and Flexible board. Therefore, the rigid-flex board is the flexible circuit board and the rigid circuit board. After pressing and other processes, they are combined according to the relevant process requirements to […]
HDI board introduction HDI board, that is, high-density interconnection board, is a circuit board with relatively high line distribution density using micro-blind buried via technology. The HDI board has inner and outer circuits. Drilling and metallization in the holes are used to connect the inner circuits of each layer. HDI boards are generally manufactured by […]
Although HDI PCB fabrication can be expensive, there are several situations where blind vias, buried vias, and microvias offer a cost-effective solution. High Density Interconnect (HDI) circuit board designs have a higher wiring and pad density than conventional PCBs, along with smaller trace widths and spaces. They require advanced PCB technologies such as blind vias, […]
