PCB design Tips:
PCB board design based on the principle of Protel DXP layout software
Protel DXP is the first design tool all rolled into one board-level design system, electronic designers from the initial project planning module to the final form of production data can be achieved in accordance with their own designs. Protel DXP design optimized to run on the browser platform, and with all of today's advanced design features that can handle a variety of complex PCB design process. By design input simulation, PCB drawing board editing, automatic topology routing, signal integrity analysis and design output technology integration, Protel DXP offers a comprehensive design solutions.
PCB board design principles include the following aspects:
1, PCB board selection
2, PCB board size
3, PCB board component placement
4, PCB board layout
5, PCB board ground
6, PCB board interference
7, PCB board pads
8, PCB board to fill a large area
9, PCB board jumper
10, PCB board high frequency wiring
PCB board selection
PCB boards are generally made of copper-clad laminates, respect from the electrical performance, reliability, processing requirements and economic indicators when considering board layer selection. Commonly used copper-clad laminate was paper phenolic copper clad laminates, copper epoxy paper laminates, epoxy glass cloth copper clad laminates, copper epoxy phenolic glass cloth laminated board, copper PTFE glass fabric laminates and multi-layer printed circuit board with epoxy glass cloth. Laminates of different materials have different characteristics. Epoxy resin and copper foil has excellent adhesion, so the higher the copper foil adhesion strength and operating temperature, can not foaming at 260 ℃ in molten tin. Less affected by epoxy resin impregnated glass cloth laminate damp gas. The best ultra-high frequency circuit board is a copper PTFE glass cloth laminate. Flame retardant in electronic equipment requirements, but also flame retardant PCB board, PCB boards are immersed in these flame-retardant resin laminate.
PCB board size
The thickness of the PCB board PCB board function should be based on the weight of the installation components, PCB board socket specifications, PCB board size and shape to withstand mechanical loads, etc. to decide. Principal should ensure sufficient rigidity and strength.
PCB board thickness common are: 0.5mm, 1.0mm, 1.5mm, 2.0mm.
From the cost, the copper film length, noise immunity considerations, PCB board size as small as possible. But the PCB board size is too small, poor heat dissipation, and adjacent wires prone to interference. PCB board production costs and PCB board area is related, the larger the area, the higher the cost. In the design of the cabinet when PCB board has, PCB board size is also limited by the size of the chassis shell must be determined before determining enclosure size PCB board size, otherwise we can not determine the PCB board size. Under normal circumstances, specified in the wiring layer wiring ban PCB board size range is size.
Best PCB board is rectangular in shape, aspect ratio of 3: 2 or 4: 3, when the PCB board size greater than 200 * 150mm, should consider the mechanical strength of the PCB board. In short, we should consider the pros and cons to determine PCB board size.
PCB board component placement
Although Protel DXP layout automatically, but in fact in the design of PCB component layout is almost done manually. PCB board component layout generally follows the following rules:
1, a special component placement
Layout of specific components from the following aspects:
1) High-frequency components
Connection between the high-frequency components as short as possible, try to reduce electromagnetic interference distribution parameters and mutual connection between the components can not susceptible to interference too close. Distance affiliated with input and output between the elements belonging should be large enough.
2) an element having a high potential difference
It should increase with a high potential difference from the elements and the connections between the elements in order to avoid accidental damage to short-circuit. In order to avoid the occurrence of creepage generally require copper film line distance 2000V should be greater than the potential difference between 2mm, if a higher potential difference for the distance should increase. Devices with high voltage, you should try is disposed in the commissioning of the reach of hand.
3) The excessive weight of components
Such elements should have a bracket, and for large and heavy, more heat elements should not be installed on the PCB.
4) heating and thermal element
Note that the heating element should stay away from sensitive components.
5) You can adjust the element
For potentiometer, adjustable inductance coil, variable capacitors, micro-switches and other adjustable components layout should consider the structural requirements of the machine, if the machine in the regulation, should be placed where the PCB is easy to adjust, if the adjusted outside the machine whose position corresponds to the position of the knob on the chassis panel.
6) The board mounting hole and bracket holes
You should set aside the mounting holes and bracket mounting holes of the PCB, as close to the hole and the hole is not wired.
