Abstract

The invention discloses a printed circuit board pad comprising a big pad and at least one small pad; the big pad comprises a copper layer; the copper layer comprises an outer copper layer, an inner copper layer wrapped by the outer copper layer and a copper layer wire connecting the inner copper layer with the outer copper layer; a gap is arranged between the inner copper layer and the outer copper layer; the outer copper layer and the inner copper layer are respectively provided with a tin layer so as to form a first sub pad and a second sub pad; the small pad is arranged one side, extending in a width direction, of the big pad. The printed circuit board pad is provided; the first sub pad is used for pastering electric elements with big sizes; the second sub pad is used for pastering electric elements with small sizes; the printed circuit board pad can paster at least two kinds of electric elements with different specifications, thereby saving space resources of the printed circuit board.

Description

technical field [0001] The invention relates to the field of printed circuit board manufacturing, in particular to a printed circuit board welding pad. Background technique [0002] With the development of electronic technology, printed circuit boards are more and more widely used in the electronic field. Pads are an important part of printed circuit boards and are used to mount electronic components. During the installation process of electronic components, the specifications of electronic components are usually selected according to actual needs, so that the selected electronic components can not only meet the requirements, but also avoid excessive margins, resulting in waste of resources. However, the size of the pad is often fixed during the manufacture of the printed circuit board, and the size of electronic components of different specifications may vary greatly. Since the solder on the pad is liquid at high temperature, when a smaller-sized electronic component is m...
