pcb board scrap refers to the waste materials generated during the manufacturing or disposal of printed circuit boards (pcb). These wastes usually include the following types: Scrap generated during the production process: including pcb board edges, test boards, defective boards and so on. These wastes may be discarded because of defects in the production process […]
A pcb motor, also known as a BLDC motor, is a three-phase brushless motor based on the Hall effect, which works by utilizing the current from an electronic controller to generate rotational force inside the motor. This type of motor is widely used in electronic devices such as power tools, automobiles, bicycles, toys, etc. pcb
The pcb board pins are an integral part of any electronic device, enabling smooth and reliable transmission of signals and power between different components on a printed circuit board. These connectors come in a variety of types, each with their own unique functions and applications. In this article, we will explore some of the most
What is a Bluetooth module?Bluetooth module is a kind of integrated bluetooth pcb board, mainly used for wireless network communication, according to the function can be divided into the classic bluetooth module, low power bluetooth module and dual-mode high-speed bluetooth module. The role of the bluetooth module is simply to replace the wired connection with
Ceramic multilayer PCB board refers to the multilayer circuit boards used in electrical products, multilayer boards with more single-sided or double-sided wiring board. With a double-sided for the inner layer, two single-sided for the outer layer or two double-sided for the inner layer, two single-sided for the outer layer of the printed circuit board, through
What is Rigid-Flex Circuitry？The birth and development of FPCs and PCBs has given rise to the existence of rigid flex pcb manufacturers. Rigid-Flex PCB technology has its origins in the military, where space saving and reliability are top priorities. This dates back to the 1980s. Today, the rigid-flex PCB market encompasses many areas from consumer
Minimum solder mask sliver (also known as solder resist) is a thin layer of polymer material applied to the surface of a PCB. Its purpose is to protect the copper circuitry and prevent solder from flowing into areas that do not need to be soldered during the soldering process. The entire circuit board is coated
How to power supplyWhen we design pcb board products, after understanding the demand, the first thing to design is the product power supply system, whether it is a product, or chip IC, pcb board power supply this step is essential.When designing the pcb board board power supply system, the first step to consider is the
In digital circuits, a pull up resistor (pull up resistors) is a resistive device used to ensure that the input signal is at the desired logic level when an input port has no device connected or is at a high impedance. They usually work between different logic devices to provide a certain voltage signal. Resistors
I.Overview of pcba testing standardsVisual inspection: through the magnifying glass and microscope and other tools on the circuit board appearance check to ensure that there are no welding errors, component damage and other issues.Functional testing: the use of special test equipment to test the functions of the circuit board to ensure that all functions work
Printed circuit board material composition refers to the relationship between the combination of various materials in the PCB board. Generally speaking, PCB boards can be divided into a variety of structures, respectively, single-sided boards, double-sided boards, multilayer boards, high-level boards and so on. 1. Single-sided PCB Substrate materials to paper phenol (phenol) copper laminate (paper
