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).
The reason for the high price of SMT proofing in small batches: The proofing cost of small batches of SMT mainly includes start-up fee, engineering fee, steel mesh fee, processing fee calculated according to conventional points, or summarized directly wit
Circuit board is the necessary material of PCBA processing plant, circuit board is mainly to provide a carrier for various electronic components, and components link together to form a complete circuit.
Although PCB automators have been around as long as engineers have known about CAD, engineers involved in designing dense boards have almost completely ignored the implementation of automated technology.
