PCB ring pad manufacturing method

PCB ring pad production methods can be used SHAPE production, in the process, to be attributed.

Circular pads - widely used in single and double sided printed circuit boards where the components are regularly arranged. If the density of the board allows, the pad can be larger and does not fall off during soldering.

Island-shaped pad - the connection between the pad and the pad. It is often used in vertical irregular arrangements. For example, such pads are often used in tape recorders.

Teardrop Pads - When pads are connected with finer traces, they are often used to prevent the pads from peeling and the traces are disconnected from the pads. This pad is often used in high frequency circuits.

Polygonal Pads - Used to distinguish pads with different outside diameters and different apertures for easy processing and assembly.

Oval Pad - This pad has sufficient area to enhance stripping resistance and is commonly used in dual in-line devices.

Open-edged pad—used to ensure that the hole in a hand-welded pad is not blocked by solder after wave soldering.

Square pads - Printed circuit board components are large and small, and when printed conductors are simple. In the manual homemade PCB, using this kind of pad is easy to implement.
