Abstract

The embodiment of the invention discloses a high-density hole circuit board hole plugging base plate which is used for PCB hole plugging. According to the scheme, the plate comprises a base plate, thebase plate is arranged on the lower side of PCB; the PCB is provided with a plurality of plug holes. Flow guide deep control grooves and air guide holes are sequentially formed in the lower sides ofthe plug holes in a base plate, a supporting block is arranged between every two adjacent flow guide deep control grooves, the width of each flow guide deep control groove is larger than the hole diameter of the corresponding air guide hole, and the hole diameter of each air guide hole is larger than the hole diameter of the corresponding plug hole. Through the supporting effect of the supportingblocks, collapse of the dense plug holes can be effectively avoided. Meanwhile, the width of the flow guide deep control groove is larger than the hole diameter of each air guide hole, the hole diameter of each air guide hole is larger than the hole diameter of the plug hole, and therefore the base plate has good flow guide and air guide effects.

Description

technical field [0001] The invention relates to the technical field of circuit board plug hole technology, in particular to a high-density hole circuit board plug hole backing plate. Background technique [0002] With the continuous development of high-density line products, the density of line wiring is getting higher and higher. The dense holes in the middle will require resin plug holes, and the plug holes require a high degree of fullness. If the plug hole is not full, there will be risks such as delamination explosion, corrosion of copper in the potion storage hole, etc. In the prior art, the backing plate under the dense holes of the high-density hole circuit board is hollowed out, which is prone to the problem of collapse of the dense holes and affects the quality of the product. Contents of the invention [0003] The embodiments of the present invention aim to solve the problem in the prior art that the dense holes of the circuit board with high density holes are...
