Description

Universal adjustable PCB electroplating uniformity improvement edge strip assembly

Technical Field

The invention belongs to the technical field of PCB (printed circuit board) processing and manufacturing equipment, and particularly relates to a universal type adjustable PCB (printed circuit board) electroplating uniformity improvement edge strip assembly.

Background

When the PCB is produced in an electroplating mode, the actual thickness of the electroplated copper at the outermost side of the production plates at two ends of the targets in the electroplating tank can exceed a set requirement value due to the characteristics of power lines. When a PCB with a fine line width and a line distance and with special control requirements on the aperture is produced, the problems of incomplete etching, small holes and incapability of inserting the components to cause scrapping are easily caused.

When a plate with a thin plate thickness is produced, the produced plate can also be bent due to the upward resistance of the floating frame to the plate and the upward pressure of the flying target, so that the quality problem caused by the excessive thickness of the electroplated copper at the middle position of one surface of the plate is caused.

Electroplating strake size is difficult unified often, cuts consuming time more when using electroplating the strake to not unidimensional production board.

The conventional edge strips need to use a clamp of the flying target, the distance between the clamps is basically 90-120mm, the conventional edge strips can only clamp one point, and the stability is poor.

The conventional edge strip has the problem of excessive thickness of edge copper of a production plate due to the fact that a certain distance exists between the edge strip and the production plate and the edge strip cannot be tightly attached to the production plate and the shielding effect is poor.

The existing electroplating edge strip is manufactured by using excess materials, the cutting width is difficult to be unified, and the current calculation cannot be accurately controlled during actual electroplating production.
