Printed circuit board (PCB) is a very sophisticated and complicated technology. Because of the complexity of the PCB assembly involved, error is inevitable. Today, we will illustrate design PCB should avoid the most common mistakes.

Bad footprint design

In the field of electronic, footprint refers to the bonding pad used for physical and electrical connection or the arrangement of the "hole". Because there are a lot of design and pattern, so have a package with reservation principle diagram. When the user wants to most of the package does not contain different footprint, can be a problem. If there is no professional help to manually create a new schematic diagram may lead to disastrous consequences. In order to ensure the PCB design is good, the best consulting specializes in custom PCB of well-known companies.

Improper fitting

PCB go line refers to the circuit board found in the connection of copper path. Current transfer line is responsible for on the circuit board. According to the current intensity, go line width must have the proper size. Need more current wider walk the line, which means the whole PCB need to adapt to the size of the increase. In order to alleviate the problem, you can use the line width calculator to ensure that the correct calculation in design of PCB.

Incorrect wireless antenna layout

A common problem of the PCB assembly is a wireless antenna layout is not correct. In order to ensure optimal antenna function, should use appropriate microstrip line. Microstrip line on the PCB, is responsible for the transmission of high frequency radio waves. Should choose the correct width, in order to achieve the biggest between transceiver and the antenna power transmission. In order to ensure the correct width, recommend the use of microstrip calculator.
