Spacing is more important in high voltage designs because the voltage across the board components makes arcing between the two conducting components more likely to occur on your PCB. Any electric arcs that do occur pose a higher risk to both the product a
PCBA contracted work and materials matters needing attention :1. Circuit design; 2. Selection of materials; 3. Selection of PCBA factory
The effect of horizontal perforation electroplating in machining multilayer circuit boards is far inferior to that of vertical perforation electroplating.
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.
The drawing maintenance method refers to the schematic diagram, analyzes the circuit principle and signal direction, and then tests the signals on the key points. Professional maintenance companies maintain circuit boards almost without drawing.
The final electrical conductivity, impedance test and solder and thermal shock tolerance test are carried out on PCB before packaging. And bake to eliminate the moisture and thermal stress absorbed by PCB in the process, and finally packaging and shipping
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.
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)
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.
The PCBA project should be completed in seven steps: first, preliminary preparation stage, second, design and development, third, design and editing of operation instruction of SMT production process, fourth, confirmation of steel mesh production ability,
