SMT SMT processing technology has the advantages of: first, high reliability, strong vibration resistance, second, small size of electronic products, high assembly density, third, high frequency characteristics, reliable performance, four, improve product
Since there are many logic components, it is easy to cause confusion and difficult to manage when they are built under one library.
PCB board making fee, material fee, SMT welding fee, steel mesh fee, PCBA fixture, PCBA test frame and packaging and transportation fee.
According to customers' individual needs, we can exchange the positions of components in the board, rearrange the circuit and pcb design layout, etc., in order to achieve the desired effect of customers.
The understanding of restricted use of metals and substances is based on the analysis of their potential harm to human body.
The following are four ways to ensure the quality of PCBA processing: 1. Quality control, 2. Inspection and testing, 3. Use high quality raw materials: 4. Professional technical team
In the study, it is found that PCB design mainly has four aspects of interference: power supply noise, transmission line interference, coupling and electromagnetic interference
Factors affecting PCB price: First, PCB materials used in different price diversity, second, PCB production process used in different price diversity, third, PCB itself difficulty caused by different price diversity, four, different customer requirements
The public power cables and ground cables on the two-sided SMB should be placed near the edge of the SMB and on both sides of the SMB. The power layer and ground cable layer can be installed at the inner layer of the multi-layer SMB, and the cables, power
Polarity means that the positive and negative electrodes or first pins of a component are in the same direction as the positive and negative electrodes or first pins on the PCB(printed circuit board). If the component does not match the direction on the P
Ways to improve SMT machining efficiency: (1) Aim for fewer component changes, (2) Focus more on PCBA assembly, (3) You should know every step of the SMT process
There are five common principles in PCB design: component arrangement rules, according to the signal direction layout principle, electromagnetic interference prevention principle, thermal interference suppression principle, adjustable component layout pri
