A collection of circuit diagrams for electronic mastery
At present, there are too many circuit board factories and they are very miscellaneous. Electronic manufacturers to choose a wide range, and it is difficult to choose the right manufacturers.
PCB basic design process
prepare the component library of schematic SCH and the component library of PCB. Component library can use protel (many electronic veteran birds have protel at that time
The surface treatment technology of PCB board and its advantages and disadvantages and application scenarios
The circuit board inside the line is mainly pure copper, that is, bare copper plate. Some people think that the gold color is copper, which is the protective layer on the copper.
Notice of layout in PCB design
It is essential to use high dielectric strength materials that can resist higher voltages before breakdown.
PCB surface treatment process characteristics
The purpose of the surface treatment is to ensure good solderability or electrical properties. Since copper tends to exist in the air as an oxide and is unlikely to remain as raw copper for long periods of time, other treatments of copper are required.
Basic inspection of PCB board
The quality of PCB directly affects the quality of the whole electronic products, PCB testing is a timely detection of problems, but also a necessary means to prevent more defective products to reduce losses.
Specification for PCB storage and inspection in SMT factory
PCB inspection contents: ① appearance inspection: ② size measurement: ③ furnace temperature test: ④ pad welding force test: ⑤ Check the PCB board factory report
Describe the fabrication process of the chip
Chip production process: 1, silicon purification to make wafers, 2, wafer coating, 3, wafer lithography development, etching, 4, mixed with impurities, 5, wafer testing, 6, chip packaging, 7, testing, packaging
The basic principles of PCB circuit board design and wiring
Wiring is generally divided into three levels: one is the layout, which is the most basic requirements of PCB design, the second is to meet the electrical performance, which is the standard to measure whether the circuit board is qualified. Three is beaut
What specific measures should be implemented to produce high reliability PCB boards?
Whether in the manufacturing and assembly process or in actual use, PCB to have reliable performance, this is very important.
