Application

Layout check
1, the board size and drawings require processing dimensions are in line.
2. Whether the layout of the components is balanced, neatly arranged, or whether they have been completely finished.
3, there is no conflict at all levels. Such as the components, the frame, the level of need for private printing is reasonable.
3, the commonly used components are easy to use. Such as switches, plug-in boards, equipment that must be replaced frequently, etc.
4. Is the distance between the thermal components and heating components reasonable?
5, heat dissipation is good.
6. Whether the line interference problem needs to be considered. [3]
Specific method editing
Purpose effect
1.1 Standardize design operations, increase production efficiency and improve product quality.
Scope of application
1.1 XXX company development department VCD Super VCDDVD audio and other products.
Responsibility
3.1 All electronic engineers, technicians, and computer drafters of the XXX Development Department.
Qualification training
4.1 There is a basis for electronic technology;
4.2 Basic knowledge of computer operations;
4.3 Familiar with the use of computer PCB drawing software.

Work guidance
5.1 Minimum Line Width of Copper Foil: 0.1MM, Panel 0.2MM Minimum 1.0MM for Edge Copper Foil
5.2 Copper foil minimum clearance: 0.1MM, panel: 0.2MM.
5.3 The minimum distance between the copper foil and the edge of the board is 0.55MM, the minimum distance between the component and the board edge is 5.0MM, and the minimum distance between the board and the board edge is 4.0MM.
5.4 The size of the pad of a common through-hole mounting device is twice the size (diameter) of the pad, and the minimum is 1.5mm for the double panel, and the minimum is 2.0mm for the single panel. (2.5mm) If you can not use the round pad, use the round lug welding Disk, as shown below (if there is a standard library,
The standard component library will prevail
The relationship between the long edge, short edge, and hole of the pad is:
5.5 Electrolytic capacitor can not touch the heating element, high power resistance, sensitive resistance, pressure, heat, etc. The minimum distance between the solution capacitor and the heat sink is 10.0MM, and the minimum distance between the component and the heat sink is 2.0MM.
5.6 Large-sized components (such as transformers, electrolytic capacitors with a diameter of 15.0 mm or more, and sockets with large currents, etc.) Increase the copper foil and tin area as shown in the figure below. The area of ​​the shadowed area should be equal to the area of ​​the pad.
5.7 The screw hole radius 5.0MM cannot have copper foil (required grounding outside) components. (according to structural drawing requirements).
5.8 Tin can not have silk oil.
5.9 pad center distance is less than 2.5MM, adjacent pad surrounding the silk screen oil package, ink width 0.2MM (meeting 0.5MM).
5.10 Jumpers should not be placed underneath the IC or under components of motors, potentiometers, and other large metal enclosures.
5.11 In large-area PCB design (above about 500CM2 or more), prevent the PCB board from bending when passing the soldering tin, and leave a space of 5 to 10mm wide in the middle of the PCB board to keep the components (wires) away from the tin furnace. When adding a layer to prevent the PCB from bending, the shaded area in the following figure:
5.12 Each transistor must be marked on the silkscreen with legs e, c, and b.
5.13 Components that need to be soldered after soldering, the plates must be driven away from the tin position. To the contrary with the tin, the size of the hole is 0.5mm to 1.0mm as shown below:
5.14 Pay attention to the design of the double panel, the components of the metal shell, when the plug is in contact with the printed board, the top layer of the pad can not be opened, must be covered with green oil or screen printing oil (such as two feet of the crystal).
