The main causes of PCB board deformation and rupture

1) PCB board deformation:

A: design problems: such as one – sided circuit, uneven distribution of the circuit will lead to.

B: excessive internal stress of PCB board: if the drying board is not enough, the stress stored in the processing process (cutting and forming)

(2) Violence PCB board:

A: the design hole is too dense, and the layers are loose after drilling.

B: the interlayer microscopic rough plating is insufficient, resulting in insufficient bonding.

(3) the PCB board sodden under the influence of process environment and storage environment.

The above is the main reason of PCB board deformation and burst board, I hope to have some help to you;We are a professional PCB factory, the products mainly include PCB gold fingers, heavy copper PCB, etc., welcome your consultation!
