PCB Layout

Shorten PCB layout design cycle for you.

PCB Layout is based on a PCB circuit schematic diagram to achieve the functions needed by the circuit designer. Excellent PCB Layout design can save production costs and improve PCBA performance. This is what is PCB Layout design? PCB layout means printed circuit board layout.

PCB layout design is a part of hardware design, it is also a very important part; In the case of reasonable hardware circuit design, it is an absolutely important index that affects the performance. Now many PCB layout engineers complete PCB layout according to the constraint rules given by PCB layout engineers or product hardware engineers.

How to make PCB layout?

How to make a PCB layout from a circuit diagram?

1. The basic requirement of PCB layout is to ensure that all networks are connected effectively. Connectivity is easy to achieve, and efficiency is a vague concept. In fact, there are no more than two kinds of digital and analog signals in the circuit. For the digital circuit, it is to ensure enough noise tolerance. For the analog signal, it is to achieve zero loss as far as possible. The layout is to place the circuit elements reasonably. How to place that is reasonable, a simple principle is that the modular division is clear, that is, someone with a certain circuit base can see which piece is used to achieve what function by getting your PCB.

2. Specific design steps for PCB layout: first, according to the schematic diagram, generate the initial PCB file, complete the pre-layout of the PCB, determine a relative PCB Layout area, then tell the structure that the structure is based on the area we give, and then give specific constraints according to the overall structure design.

3. Before PCB Layout wiring, it is generally necessary to understand the entire PCB board cascade design, that is, to plan all the wiring layers as an optimal wiring layer, a suboptimal wiring layer, an optimal wiring layer, which is the complete ground level of adjacent interviews. This layer is generally used to distribute important signals (including all signals in DDR, differential signals, analog signals, etc.). Other signals (I2C, UART, SPI, GPIO) go to other layers and ensure that only the circuit-related signals (such as DDR, network ports, etc.) exist in important areas. Draw the board edges, positioning ports, and some prohibition zones according to the constraints of the structure, and then complete the placement of the connectors.

4. Placement principle of PCB components: In general, the master MCU is placed in the center of the board, then the interface circuit is placed close to the interface (e.g. mesh, USB, VGA, etc.), and most of the interfaces have ESD protection and filter processing. The principle followed is protection before filtering.

5. Power modules of PCB, generally the main power modules are placed at the power entrance (e.g. system 5V), and discrete power modules (e.g. 2.5V supplied by the module circuit) can be placed in places where the same power network is dense according to the actual situation. Power supply and power circuit, first of all, must ensure enough carrying capacity, that is, the power supply's entire return circuit strength is as thick and short as possible, called from the EMC angle, the return circuit is a loop, forming a loop antenna, radiating to the outside, so as to reduce the area of the loop as much as possible.

6. PCB layout has some internal circuits that are not lead to plug-ins. We generally follow such basic principles as high-speed and low-speed zoning, analog and digital zoning, interference source, and sensitive receptor zoning.

7. For a single circuit module, follow the current flow direction when the circuit is designed.

iPCB's PCB layout methodology will ensure product performance, time-to-market, unit cost, and manufacturing yield requirements are met. ipcb will simulate to provide a 'right first-time' guarantee in the critical areas of impedance, crosstalk, and signal integrity. This exercise will remove the impact of rework on cost and time scales. Our simulation results will allow design steps to be taken that significantly reduce design risk.
