PCB pad type

Time:2023-07-05Views:


Square solder pads are commonly used when the components on a printed board are large but few, and the printed wires are simple. When manually making PCBs, using this type of solder pad is easy to achieve. Circular pad - widely used in single and double-sided printed boards with regular component arrangement. If the density of the board allows, the solder pad can be larger to prevent detachment during welding.

Island shaped pad - The connection between the pad and the pad is integrated. Commonly used in vertical irregular arrangement installation. For example, this type of pad is often used in tape recorders.

Teardrop solder pads - often used when the wire connecting the pads is thin to prevent peeling and disconnection of the wire from the pads. This type of pad is commonly used in high-frequency circuits.

Polygonal pad - used to distinguish pads with similar outer diameters but different apertures, making it easy to process and assemble.

Elliptical pads - These pads have sufficient area to enhance peel resistance and are commonly used in dual inline devices.

Open end solder pad - commonly used to ensure that the manually repaired solder pad holes are not sealed by solder after wave soldering
