The design of PCB starts from determining the size of the board. The size of PCB is limited by the size of the case shell, so that it can be placed into the shell exactly. Secondly, the connection mode of PCB and external components should be considered.
As an electronic engineer design circuit is a necessary hard work, if the PCB design is not reasonable performance will be greatly compromised.
SMT patch BOM list arrangement Note: 3. The description must be clear. 4. There are some crucial electronic components. Considering the fluctuations of the component market and the cost, 5. 6. Coordinate values required by coordinate T/B to distinguish po
Quick solution to PCBA short-circuit problem: 1. Use short-circuit positioning analyzer for inspection, 2. Light up the short-circuit network on the PCB diagram. 3. In case of the same short-circuit in batches, take a board to operate the secant line and
Whether in the manufacturing and assembly process or in actual use, PCB to have reliable performance, this is very important.
PCB board test system will have a new design idea, the use of automatic test system based on USB bus and virtual instrument design idea, give full play to the role of the computer
Many manufacturers are using ceramic COBs to process LED, because this can further reduce the cost of LED energy-saving lamps.
This battery, this battery, that battery, unfortunately, has not yet been mass-produced on the road, and there are several experimental bus routes in use.
In the design of PCB electromagnetic compatibility, the main problem that needs attention is the interference problem of power supply and ground.
Want to really fast production of high precision, good performance, and can save the cost of PCB circuit board, this is undoubtedly the biggest challenge for circuit design engineers.
At present, the PCBA processing and assembly of circuit boards are basically welded on the printed circuit board by soldering the electronic parts. This welding process can be achieved by SMT or wave soldering.
Solder paste printing principle: solder paste contact solder paste through the steel plate hole, printed on the substrate tin pad (PCB plate solder plate).
