Optimization design skills of circuit board heat dissipation :1. Heat dissipation by PCB board itself,2. High heating device with radiator, heat conduction plate,3. For the use of free convection air cooling equipment, the integrated circuit is arranged i
Surface mount technology is very convenient in the manufacture of many PCBS. Reliable and fast professional tools handle installation to ensure that there is no room for human error while speeding up the process.
Common treatment methods are added sewing capacitor and bridge :1, sewing capacitor, 2, bridge, 3, multi-layer wiring, 4, lead bending less, the better, 5, the shorter the better, 6, lead layer alternating less, the better, 7, pay attention to parallel cr
There are the following factors affecting PCB welding quality: PCB diagram, circuit board quality, device quality, device pin oxidation degree, solder paste quality, solder paste printing quality, placement machine programming accuracy, placement machine
PCB design service process: 1. The customer provides schematic diagram to consult PCB design; 2. 2. Evaluate quotation according to schematic diagram and customer design requirements;3. The customer confirms the quotation, signs the contract and pays the
A perfect PCB board not only needs to do the component selection and setting is reasonable, but also needs to have good signal conduction performance.
The following operations will be carried out in the maintenance technology: 1, inspection of components, 2, welding state analysis, 3, detection of components direction, 4, tool inspection of components, 5, power-on test
Width and spacing of printed wire are important design parameters, which affect not only the electrical performance and electromagnetic compatibility of PCB, but also the manufacturability and reliability of PCB.
Because the wider the printed line is, the smaller the inductance is, the lead line from the pad to the hole should be widened as far as possible, and the width of the pad should be the same as far as possible. In this way, even the capacitance of 0402 pa
Component layout shall be designed according to SMT electronic processing production equipment and process characteristics and requirements. Different processes, such as reflow welding and wave soldering, have different layouts for components.
To provide you with effective skills to improve PCB design spread rate and design efficiency: 1, determine the number of PCB layers, 2, design rules and restrictions, 3, component layout, 4, fan out design, 5, manual wiring and key signal processing, 6, a
One of the major trends of PCB design is gradually inclined to open source hardware mode and control system, another is the explosive growth of development board, PCB design tools are now being used in more and more development board design.
