Abstract

Embodiments of the present invention disclose a PCB package library structure and a packaging method, and solve the technical problem of unsafe hidden dangers caused by the case that due to continuous tin short circuiting of wave soldering, PCB short circuiting is caused and a PCB is burnt out so as to enable a product not to be released on time, and even short circuiting is caused and the PCB is on fire to cause a fire disaster . The PCB package library structure disclosed by the embodiments of the present invention comprises a plurality of drill holes for inserting welding ends or pins of components, wherein a circle of coordinate deviated wave peak bonding pad is arranged on the periphery of each drill hole; and a distance between the wave peak bonding pads between the peripheries of every two adjacent drill holes is not less than 1 mm.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a PCB package library structure and a package method. Background technique [0002] With the rapid development of electronic products in recent years, the demand for high current on printed circuit boards is increasing. Many single boards use power connectors to input and output power, and the high-current connectors generally used in the industry are plug-in pin connector. [0003] Therefore, it is necessary to solder by wave soldering. Wave soldering refers to the molten solder (lead-tin alloy), which is sprayed by an electric pump or an electromagnetic pump into a solder wave peak required by the design, or by injecting nitrogen into the solder pool. It is formed to make the printed board pre-installed with components pass through the solder wave to realize the soldering of the mechanical and electrical connection between the component soldering end or the pin and...
