It is to check the rationality of PCB design, test its possible problems or defects in the production process, to ensure the functionality and appearance of the product, and improve the production yield of the final product.
Milling PCB board is a method of processing printed circuit boards (PCBs) using CNC milling technology. It cuts and repairs PCB boards through milling methods to form the final form of the product. With the booming of the electronics market, the demand for PCB milling technology is getting higher and higher. Reasons affecting the accuracy
A drill for pcb board is a device used to perform precise drilling operations on PCBs for the subsequent installation of electronic components such as resistors, capacitors, IC pins, and various other connectors. Drilling is a critical step in the PCB manufacturing process as it ensures electrical interconnections between internal layers of the board as
3D packaging semiconductor technology, also known as three-dimensional integrated circuit packaging technology, is an advanced semiconductor packaging method that allows multiple chips to be stacked together in a vertical direction to provide higher performance, smaller package size and lower energy consumption. The core of this packaging technology lies in the stacking of multiple chips in
PCB prepreg refers to the resin matrix in a certain way impregnated with reinforcing fibers, the formation of a uniform thickness of the strip or sheet-like semi-finished products, is a composite material from the raw material to the products of the transition of the intermediate products. It contains matrix resin and reinforcing fiber. Prepreg can
The fundamental difference between FPGA vs CPU lies in the difference between software and hardware; CPU is a Von Neumann structure, which executes a series of instructions serially; while FPGA can realize parallel operation, like embedding multiple CPUs in a chip, whose performance will be ten or a hundred times that of a single CPU.
PCB Via fill is a material used to fill through holes in a PCB board. Through holes are holes punched in a PCB to connect different circuit layers so that current or signals can flow through. The purpose of through-hole fillers is to prevent liquid solder pads or other impurities from remaining in the through-holes,
Bendable Circuit Board, or Flex PCB, is a type of circuit board that is manufactured using a flexible substrate. Its best feature is that it can be flexibly bent without affecting its performance or conductivity. Compared to traditional rigid circuit boards, flexible circuit boards have better adaptability and applicability. FPC is the United States in
Residual copper in circuit boards is a common by-product of the manufacturing process, and excessive residual copper not only occupies space, but also may cause pollution to the environment. Therefore, how to remove copper from pcb has become the focus of attention of the majority of enterprises. Residual copper refers to the copper foil that
HDMI splitter is a way to HDMI signal into more than two-way function of the device, and split the signal and the source signal is the same, can be synchronized in real time. In layman’s terms, it is an HDMI interface to expand into multiple HDMI interfaces, so that you can use a host at
What is a splitter?It is an electronic device that is used to distribute electrical signals or data streams to different routes. It can split an input signal into multiple output signals according to a certain pattern, each output signal has the same electrical characteristics as the input signal, and the number of output signals can
