Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, and in particular to a PCB board pressing anti-slip fixture. Background Technology

[0002] In PCB manufacturing, lamination is the core process for multilayer board forming. It requires high temperature and high pressure to bond the conductive layer and the insulating layer into a whole. Its quality directly determines the interlayer bonding strength, dimensional accuracy and the yield of subsequent processes. With the increasing demands of new fields for products, the alignment error needs to be controlled within a small range. However, during the lamination process, factors such as the flow of prepreg resin, the difference in the thermal expansion coefficient of interlayer materials and the fluctuation of equipment pressure can easily cause relative slippage between the PCB board and the bottom mold and multilayer board, resulting in defects such as interlayer misalignment and blind buried via misalignment.

[0003] Some designs rely on a single screw for locking or a snap-on plate for clamping, which can easily lead to poor closure in the unlocked areas due to uneven pressure transmission. Furthermore, operating each screw individually is inefficient and may cause misalignment due to force applied to one side first. Other designs use a fixed positioning structure, which has poor adaptability and cannot meet the fixing requirements of PCB boards of different sizes. The adjustment process is cumbersome. Although some designs use spring-driven clamping, they lack buffering and progressive pressure control. Either excessive pressure will damage the pins on the PCB board surface or leave indentations, or insufficient pressure will result in unstable anti-slip effect. At the same time, the top plate is often fixed on one side or has a simple snap-on design after closing, which is prone to loosening when pressure is applied, further increasing the risk of slippage. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a PCB board pressing anti-slip fixture, which aims to improve the problem of easy slippage during use of the device in the prior art.
