Input resistance is a measure of the amplifier’s effect on the signal source. The larger the input resistance, the smaller the current taken by the amplifier from the signal source, and the larger the signal voltage obtained at the input terminal of the amplifier,
The sensitivity of electronic equipment is getting higher and higher, which requires the anti-interference ability of the equipment to be stronger and stronger, so PCB design has become more difficult
Before explaining the inspection work after the PCB wiring is completed, I will introduce three special wiring techniques for PCB. The routing of PCB LAYOUT will be explained from three aspects: right-angle routing, differential routing, and serpentine routing.Today author from QiHe smt pick and place machine discussing about it with you . Right-angle routing (three […]
The selection of single-chip microcomputer is an important and troublesome thing. If the type is selected properly, the product will be cost-effective and work stably; otherwise, it may cause excessive product cost or affect the normal operation of the product, and may even fail to meet the pre-design requirements at all.
PCB circuit board design is a critical and time-consuming task, and any problems require engineers to check the entire design network by network and component by component.
Printed circuit boards (PCBs) are the supporting components for circuit components and devices in electronic products. It provides electrical connections between circuit components and devices. With the rapid development of electronic technology, the density of PCBs is getting higher and higher.
n pcb circuit diagrams, graphical symbols identify network components and devices. International letter symbolism is based on the Roman and Greek alphabets. Qihe SMT Line Equipment today will share with you some common symbols and their meanings .
LED’s open the way to new applications and markets in various different fields with a broad spectrum of requirements.
What should be paid attention while designing a single chip microcomputer control board ？The most basic process of designing a circuit board can be divided into three major steps: the design of the circuit schematic diagram, the generation of the netlist, and the design of the printed circuit board. Whether it is the device layout or wiring on the board, there are specific requirements.Together discuss with qihe smt equipment editor today
The smt engineer of Qihe pnp machine team came to a famous industrial university to help setup the school’s laboratory build a small TVM802 smt production line,To help researchers better complete research design and technology development.
