In PCB (Printed Circuit Board), there are many common mistakes in design. They are mainly located in communication and signal transmission. Customers will always ask for circuit models, but this may not be practical.
PCB board design professionals must provide the best guidance to facilitate their work. The possibility of designing these circuit boards is very high, and with it comes errors. Here, we will tell you how to avoid them so that you will not delay delivery.
The 8 most common mistakes of PCB layout design
If you know that errors have become daily problems and understand the root causes of errors, you can increase the success rate of your design. In view of this, we have created a list that lists the 8 most common lists in PCB board design. The idea is that you don’t repeat or avoid using them at all costs:
1. Component layout on PCB
When the components are unevenly distributed on the PCB, the demand cannot be met from an electronic fms rc jet point of view. In view of this, the following points must be considered:
In the PCB layout design, protect all components of the product, such as boxes, screws, nuts, studs, housings, etc. If you don’t have to run the track to provide more space for the element, you must figure out the dimensions. Wiring that connects the card to other external components. Space may be small and does not allow for a comfortable and friendly layout on the PCB. If no prediction is made, the route must be moved in the process. Placing the components in enough space helps to optimize the space and provide greater comfort inside the box
2. Plan routing
If the wiring is not planned, it may cause PCB failure or malfunction. For the following reasons, to achieve good routing, hobbystar location is the key: locate them according to the electrical characteristics of the PCB, according to the nature of the component, find the circuit according to the component
3. Very large tracks
When wiring the PCB board design, wiring the PCB may be a headache. Routing channel is a solution, it refers to the size of the track. If we have a better understanding of this concept, we will have more real orbital space value.
4. Analog quantity and digital quantity are not separated
By using grounding in grooves or gaps, most analog and digital components can be separated. In this case, it is ideal to place them in a suitable space without having to cut into the ground. At this point, we recommend separating the analog and digital tracks. The purpose is to avoid coupling in different directions.
5. Do not wire at about 45°
In the past, in the PCB layout design, a 90-degree trajectory was drawn, but this change has changed because it is thought to produce a radioactive emission. However, research and research continue to evolve, showing how serious the situation is. For frequencies higher than 100 MHz, the signal may be lost by 5% to 9%. If the frequency is higher than 500 MHz or 1 GHz, it is recommended to use the curve. This is why a 45-degree angle can improve the process and help make more precise use of wiring channels.
6. Zigzag lines
When doing PCB board design, it is important to improve the PCB wiring to resemble a snake’s movement. This is tortuous, helps avoid obstacles, and has a more efficient route. This is based on the viewpoint of space-distance-connectivity.
