Как выбрать производителей обработки печатных плат: во-первых, существует ли стандартный поток процедур; Во-вторых, применяется ли стандарт; В-третьих, время доставки
Мировая индустрия печатных плат в основном распространяется в Китае, Тайване, Японии, Южной Корее, Европе и США. С передачей мировых мощностей по производству печатных плат в Китай в последние годы Китай стал крупнейшим в мире регионом производства печатн
Large scale, top ranking PCB enterprises mainly produce large batch board, PCB enterprises positioned in small batch board are relatively few, in addition to the company, the domestic production of small batch board representative enterprises mainly Chong
There are two basic principles to determine the distance between the multilayer capacitor power layer and the edge of the board in the capacitor design of multilayer PCB board, and to solve the distance between the printing strip: 20-H method and 3-W meth
In case of abnormal tools during transportation, it is necessary to ensure the safety of personnel and goods, and do a good job in isolation and reporting.General principles to be followed in the layout design of multilayer printed boards
Selective welding processes include flux spraying, circuit board preheating, dip welding and drag welding. Flux coating process in selective welding, flux coating process plays an important role.
PCB design, not only technology, but also art, art involves a lot of subjective factors, so engineers should also pay attention to improve their own culture.
The negative film is used for direct etching, and the corrosion resistance left after development is a circuit, which is etched directly with acid etching solution.
Most of the equity is controlled by banks and trust shareholders or occupies a large proportion, which is not conducive to stand out in the competition of PCB market in the future.
which also means that the frequency is higher and higher, the requirements of the circuit board substrate is also higher and higher.
For PCB products in these emerging markets, the process and raw materials of high-end high frequency and high speed pcb board need to be comprehensively upgraded, and the technical barriers are comprehensively improved. The key to realize high frequency o
