Frontal temperature gun circuit board PCBA processing
When the infrared frontal temperature gun is aimed at and close to the distance between the measured object and the tube measured by the sensor, the infrared sensor plate will collect the temperature and convert it into an electrical signal.
Ground suppression and interference in PCB design
The main reason of electromagnetic interference caused by ground wire in PCB is the impedance of ground wire. When an electric current flows through a ground wire, a voltage is generated on the ground wire. This is ground noise. Driven by this voltage, a
What materials and classification do pcb circuit boards have?
Copper clad plate is the basic material of electronic industry, mainly used in the processing and manufacturing of printed circuit board (PCB), widely used in TV, radio, computer, computer, mobile phone, communication and other electronic products.
What are the problems affecting the quality of PCB copy board
in the process of PCB copying board, PCB scanning is undoubtedly the first step of all processes. Therefore, we first get a good PCB board, and then it must be scanned by the computer, and then backup the relevant parameters and the original PCB layout.
What is the relationship between chip decryption and PCB copy board?
PCB copy board and chip, the two are more like the relationship between the lips and teeth, think about it carefully, PCB copy board is like the shelter of the chip, without the shelter, the chip can only wander around, and can not play their role.
What is PCB board copy board?
Copy board is also called cloning or imitation, is a product design of PCB board reverse technology research, copy board is equal to copy board, copy the circuit board on the hand, and then mass production.
Process introduction of subtraction method and addition method for PCB copy board design
PCB copying board design and manufacturing is from the subtraction method to addition method, this paper mainly describes the PCB subtraction method and addition method related concepts and manufacturing process, for your reference to learn!
PCB copy board four basic steps
PCB copy board design step two: Draw your own definition of non-standard device package libraryIt is suggested to put the devices drawn by yourself into a dedicated design file of PCB library.
Common mistakes in PCB design
Printed circuit board will appear in almost every kind of electronic equipment, is the basis of the entire electronic products.
PCB board copy board is how to come step by step
Many people misunderstand the concept of PCB copying board. In fact, with the continuous development and deepening of the copying board industry, today's concept of PCB copying board has been extended in a wider range.
What are the PCB inspection standards
For PCBS that have been identified as keyboards in the device, these key characteristic parameters and indicators must be centralised and checked from the head in addition to regular inspection. To the toes.
