Kingford focus on the high-quality PCBA order demand of "Multiple varieties, medium and small batch, and short lead time".
Fanyi PCB design Company to military quality PCB design requirement PCB design can not be arbitrary, there are certain rules. Fanyi circuit military quality PCB design has the following requirements
Wiring is generally divided into three levels: one is the layout, which is the most basic requirements of PCB design, the second is to meet the electrical performance, which is the standard to measure whether the circuit board is qualified. Three is beaut
PCB design impedance matching: PCB design impedance matching refers to a suitable collocation between the signal source or transmission line and the load. According to the access mode PCB design impedance matching has serial and parallel two ways; Accordi
Polygon filling deviation usually occurs when polygon plating copper on multi-grid circuit boards. While it does not have a standard based on a single grid, it can provide service beyond the required life of the boards.
Circuit board design required data: 1. Circuit diagram, necessary, 2. Circuit consumption power calculation, not necessary, 3. Circuit diagram Electrical list, not required, 4. Component table, required, 5. Circuit board design drawing, required, 6. Circu
Circuit board design and production process: 1. Preparation of production materials, 2. Circuit board production and manufacturing, 3. Production and design
When selecting circuit board components based on component packaging, the following needs to be considered: component packaging selection. Grounding methods. Virtual component packaging. Verify complete material list data. Sort. Excess gate circuit.
With the popularity of SMT lead-free process technology, the demand for PCB substrate is getting higher and higher. The performance of PCB can be improved from the design of PCB.
The application of wave-crest welding technology and reflow welding technology are completely different in component layout design, PCB and pad graphic design and hole design.
In concept, wireless transmitter and receiver can be divided into two parts: fundamental frequency and radio frequency. Includes the frequency scale of the input signal of the transmitter and the frequency scale of the output signal of the receiver.
The first step to enter the PCB circuit board system is to set the PCB preset background, including setting the grid volume and type, cursor type, version layer reference, wiring reference, etc.
For you to introduce the circuit board design precautions and operation skills :1, the processing level definition to be clear, 2, the distance from the copper foil frame can not be too close, 3, can not use the filler block picture welding pad, 4, electr
