Description

Oil ink permeation prevention structure for hole plugging process

Technical Field

The utility model relates to a consent technical field specifically is a consent technology is with grease proofing china ink infiltration structure.

Background

Printed circuit boards, also known as printed circuit boards, are providers of electrical connections for electronic components. The printed circuit board is generally denoted as "PCB" and cannot be called "PCB board". The circuit board can be divided into a single-sided board, a double-sided board, a four-layer board, a six-layer board and other multi-layer circuit boards according to the number of the layers of the circuit board. Since printed circuit boards are not typical end products, they are somewhat confusing in the definition of names such as: the motherboard for a personal computer is called a motherboard and cannot be directly called a circuit board, and although the circuit board exists in the motherboard, the motherboard is different from the motherboard, so that the two aspects cannot be said to be the same when evaluating the industry. For another example: because of the integrated circuit components mounted on the circuit board, the news media is called an IC board, but it is not substantially identical to a printed circuit board. By printed circuit board we generally say bare board-i.e. a circuit board without upper components.

The short circuit caused by the fact that tin penetrates through the element surface from the conducting hole when the PCB passes through wave soldering is prevented; particularly, when the via hole is placed on the BGA bonding pad, the via hole is plugged firstly, and then gold plating is carried out, so that the BGA is convenient to weld. The existing hole plugging needs to be carried out through resin ink, but the hole plugging is easy to expose in the numerical value and ink solidification process, so that the product quality is influenced. Most of the existing solidification processes are natural solidification, so that a leakage-proof and seepage-proof device is needed to assist hole plugging operation.
