What is the meaning of Multi-layer in PCB Board?
A PCB board is a printed circuit board. A multilayer PCB is also a multilayer circuit board, also called a multi-substrate board. The increased density of integrated circuit packages leads to a high concentration of interconnections, which makes the use of multisubstrate necessary.Unexpected design problems such as noise, stray capacitance, crosstalk, etc. have arisen in […]
PCBA Production Process and Equipment Introduction
1. solder paste printing machine Modern solder paste printing machines are generally composed of plates, tin paste, embossing, and transmission boards. Its working principle is: firstly, the circuit board to be printed is fixed on the printing positioning table, and then the solder paste or the red glue is printed on the corresponding pad through […]
In the PCBA processing, how does the program “burn” into the IC chip?
In PCBA processing, in order to achieve the expected specific functions of the board, in addition to hardware, software support is required. If you have software, you need to add the “burn” program in the PCBA processing process – “handle” the program into the IC. Definitions: The process of “handling” the program into the internal […]
SMT Manufacturing Process – First Piece Mechanism
In the SMT production process, there is a common error-proofing method, which can reduce the risk of wrong parts, reduce the probability of errors, and effectively improve the quality of the entire production. This is the first mechanism. The so-called first piece mechanism is to make a sample before the official production. This board will […]
SMT Production Process for Electronic Circuit Board
With the development of miniaturization and thinning of electronic products, many pcb circuit boards in electronic products are now using SMT manufacturing technology, namely surface mount technology, that is, all electronic components are welded on the surface of circuit boards.There is no need to insert it through the reserved holes in the circuit board and […]
Main characteristics and cost analysis of flexible circuit boards
1. Flexibility and reliability of flexible circuits At present, there are four kinds of flexible circuits: single side, double side, multilayer flexible board and rigid flexible board. (1) Single-sided flexible board is the lowest cost, when the electrical performance requirements are not high PCB.The single-sided flexible board should be used for single – sided wiring.It […]
SMT Process of PCB Introduction and Precautions
The mainstream circuit board assembly technology in the SMT industry should be full-flow reflow soldering,is divided into single-panel reflow and double-panel reflow. Which SMD parts should be placed on the first side of the reflow oven? Generally speaking, the smaller parts are recommended to be placed on the first side of the reflow oven, because […]
Learn to build an intelligent PCB production line
At present, the PCB manufacturing industry is undergoing a huge transformation, that is, it can use artificial intelligence (AI) to simplify the production process and improve production results in ways never seen before. AI has become a market disruptor, and the importance of adding AI to PCB manufacturing is as critical as moving to Industry […]
