PCB Global Market Space is Vast The PCB industry is the industry with the largest output value among the global electronic component subdivision industries. In 2017 and 2018, the global PCB output value grew rapidly, with an increase of 8.6% and 6.0% respectively. Due to the weak macroeconomic performance and the impact of the Sino-US …
In daily life, most PCB boards are green, but sometimes, we can see blue and even black PCBs in addition to green. Why do PCB boards choose different colors? Why is green the most common color? This paper will reveal the secret of “colorful” printed circuit boards. Green ink is the most widely used ink with the …

There are many silk screen letters on the PCB, such as R109, c113, Q105, d206, etc. What do these letters / numbers mean? The letters on the PCB board represent the abbreviation of electronic components, and numbers often follow the letters, which are also meaningful. The Letters on PCB Board PCB Alphabet Meaning Table Letter Representative …

What is Impedance Circuit Board? For PCB factories, boards with impedance lines are commonly known as impedance boards. The follow image is one of the common impedance boards. Generally, impedance is only made for high-speed boards, and the line width tolerance of impedance lines should be controlled to 5%-10% in the production process, while the tolerance …

There are a lot of parameters to be confirmed when making PCB. It’s easy to understand the parameters such as size, quantity, plate materials, thickness, solder resist color and silk screen color. But there is some parameters that are not so easy to understand, such as copper thickness, minimum line width / line distance, minimum aperture, through-hole …
With the development of electronic products, the technical demand of using FPC soft board to connect to PCB is higher and higher. But how to connect them? Following we will introduce several common connection and welding methods between FPC and PCB in the industry. FPC ( “flexible printed circuit board” or “flexible circuit board”) is …
General selection principle of grounding mode For a given equipment or system, it is regarded as a high-frequency circuit when the length of the transmission line L > in at the highest frequency of interest (corresponding wavelength). On the contrary, it is regarded as a low-frequency circuit. According to the rule of thumb, for circuits …
For the actual PCB, the best “ground” should be a complete and common ground plane, which can reduce the crosstalk between the wires on the PCB and reduce the electromagnetic interference. Incomplete Ground Plane Ground plane segmentation usually occurs on digital analog mixed PCBs. Both the ground plane and the power plane are the same …
Grounding is one of the important means to suppress electromagnetic interference and improve the EMC performance of electronic equipment. The correct grounding mode can not only improve the ability of the product to suppress electromagnetic interference, but also reduce the external EMI emission of the product. Is there a general grounding method for reference? The …

The biggest difference between flexible electronic printing and printed circuit board is that the current carrying capacity of wires is different. The heat dissipation capacity of flexible electronic printing is relatively poor, so the current carrying capacity it can bear is relatively small; The heat dissipation capacity of printed circuit board is relatively strong, and …
