High-quality PCB soldering service is an important guarantee for the quality of the product.

The PCB soldering service, as its name suggests, refers to the connection between components by means of electric welding. On a printed circuit board, the electrical connections of all components are made through the pads.

The pad in the PCB soldering service is the most important basic unit in PCB design. Different PCB soldering services are provided according to different components and soldering processes, and the pads in the PCB soldering service of the printed circuit board can be divided into two types: non-via pad and via pad.
One: The non-via pad in the PCB soldering service is mainly used for the soldering of surface mount components.
Second, the via pad in the PCB soldering service is mainly used for the soldering of pin-type components.

The choice of the shape of the pad is related to the shape, size, layout, heat, and direction of the component. The designer needs to make a comprehensive selection according to the situation. In most PCB design PCB soldering services, designers can provide different types of pads, such as round pads, rectangular bumps, and octagonal pads. Circular pads are the most common type of pad. For soldering, high-quality PCB soldering service is an important guarantee for the quality of the product. The pad size has a great influence on the manufacturability and life of the SMT product, so the size of the pad is the basis of the PCB soldering service and the basis for the customer to choose the manufacturer.
