Common pcb panel sizes (which can be considered industry standards) include: 24” x 18”, 12” x 18”, and 24” x 9”. Note that these panels have 0.5” margins on all sides and 0.1” space between the individual boards that make them up. It is also worth noting that the 24 x 18” panel is the
What is pcb coating material?PCB coating is a thin, polymer film (about 12-200 microns) applied to the populated board. It provides electrical insulation and protects the board from external components or the adverse conditions of the environment in which it is used. Harsh factors include (but are not limited to) the following: Benefits of Conformal
Dry film pcb is a photosensitive polymer film, usually composed of polyester support film, photoresist layer and protective film. In the PCB manufacturing process, through the exposure and development steps, the dry film can form a precise conductive pattern. Dry film is an important consumable for making dry film PCB and is widely used in
Flex pcb production starts with designing the circuit board structure and layout. A flexible circuit board is a printed circuit board that is designed to be flexible and bendable. Unlike traditional rigid circuit boards, flexible circuit boards are made of thin, flexible materials such as polyimide or polyester film. These materials allow the circuit board
Main Steps in Printed circuit board fabrication:To get a clear picture of the printed circuit board fabrication process, let’s take a step-by-step look at how a PCB develops from an idea on paper to the final product.

The audio ic board is one of the important components in the speaker equipment, and it undertakes many key functions. First, the audio IC board is responsible for receiving the signal from the audio source and converting the signal into current, then amplifying the current through the power amplifier part, and finally driving the speaker
In the electronics industry, pcb plays a vital role. It is the support of electronic devices and the key to circuit connection. In the development history of pcb, multi-layer pcb has been widely used, while 3 layer pcb is relatively rare in actual circuit board processing due to its unique structure and performance.Why are three-layer
2 layer flex pcb is a printed circuit board designed to be flexible and bendable. Unlike traditional rigid circuit boards, flexible circuit boards are made of thin and flexible materials such as polyimide or polyester film. These materials allow the circuit board to adapt to various shapes and fit into small spaces, making it ideal
Pins have various functions, and the most common ones are power pins, ground pins, input pins, and output pins.
