SMT SMT processing technology has the advantages of: first, high reliability, strong vibration resistance, second, small size of electronic products, high assembly density, third, high frequency characteristics, reliable performance, four, improve product
With the high density interconnection design of PCB board and the progress of electronic technology, carbon dioxide laser processing equipment has become an important tool for PCB board manufacturers to process microholes.
OSP is Organic Solderability Preservatives, which refers to the coating of OSP film on the bare brass plate (double-sided/multilayer/two-layer) in place of the original protective treatment such as tin spraying on the surface of the plate.
The high-speed digital signal is determined by the edge speed of the signal. It is generally believed that the rise time is less than 4 times the signal transmission delay can be regarded as high-speed signal.
When wiring the printed board, the position of the components on the board should be determined first, and then the ground wire and power cord should be distributed. When arranging high speed signal lines, it is best to consider low speed signal lines.
In the process of purchasing PCBA, we need to pay urgent attention to PCBA quality control points, and adopt a professional perspective to examine whether each PCBA board meets the application requirements of electronic products.
When the overshoot is serious, the protection diode will fail prematurely because of its work. Severe downstrokes can cause false clock or data errors (misoperation)
The snake line on PCI board is to adapt to the line length requirements of PCI 33MHzClock. If in the general ordinary PCB board, is a distributed parameter LC filter, can also be used as a radio antenna inductor coil, short and narrow snake wire can do fu
Since there are many logic components, it is easy to cause confusion and difficult to manage when they are built under one library.
PCB board making fee, material fee, SMT welding fee, steel mesh fee, PCBA fixture, PCBA test frame and packaging and transportation fee.
According to customers' individual needs, we can exchange the positions of components in the board, rearrange the circuit and pcb design layout, etc., in order to achieve the desired effect of customers.
