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 …

More than 80 years have passed since Paul Eisner officially invented PCB manufacturing technology in 1936, and PCB has developed rapidly and has become an indispensable foundation for the electronics industry. Although the PCB generally only accounts for 5~10% of the cost of the finished circuit board, the reliability of the PCB is far more …

The basic purpose of PCB surface treatment is to ensure good solderability or electrical performance. Since copper in nature tends to exist in the form of oxide in the air, it is unlikely to remain original copper for a long time, so it needs other treatment. Comparison of 9 Current Mainstream PCB Surface Treatment Processes …

What is the Thermoelectric Separation Substrate? The circuit part and the thermal layer part of the substrate are on different circuit layers, and the thermal layer part directly contacts the heat dissipation part of the lamp bead to achieve the best heat dissipation (zero thermal resistance) effect. And the material of the substrate is generally …

After reflow soldering or wave soldering, PCB may be deformed, such as bending and warping, or even cracked and layered. However, problems such as cracking and delamination are rare, while deformation problems such as plate bending and warping are common, and often lead to abnormalities such as empty welding, faulty welding, monument erection and offset. …
Printed circuit boards (PCBs) are widely used in various electronic devices. You can find them in mobile phones, computers and complex machines. If the PCB has defects or manufacturing problems, it may cause the final product to fail and cause inconvenience. In these cases, the manufacturer will have to recall these equipment and spend more …
