Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the pulse rectifier in the prior art can only be placed next to the electrolyte tank when it is arranged in the factory because the module occupies a large space, resulting in a large land occupation, thereby providing a Pulse rectifier with reduced footprint for factory layout

Abstract

The invention provides a pulse rectifier, which belongs to the technical field of pulse equipment, and comprises a preceding-stage power supply and a power module which are arranged in a split manner,the preceding-stage power supply and the power module are suitable for being arranged side by side in a frame, and the bottom end of the frame is suitable for being supported above electroplating orelectrolysis equipment; according to the pulse rectifier disclosed by the invention, the preceding-stage power supply and the power module are arranged in a split manner, so that the preceding-stage power supply and the power module can be arranged in the frame side by side, and the frame can be supported above electroplating or electrolysis equipment due to reduction of the overall height of thepower supply, thereby preventing the arrangement of the power supply from occupying the ground space and saving the factory land cost.

Description

technical field [0001] The invention relates to the technical field of pulse equipment, in particular to a pulse rectifier. Background technique [0002] Pulse rectifiers are used to provide direct current for the distribution of copper electrochemical deposition on circuit boards. With the increasing complexity, thickness, path density, and shrinking aperture and path width of circuit boards, traditional direct current electroplating is becoming more and more Unreliable and even lead to poor quality. [0003] To balance the copper thickness in the holes or microvias, the current density is forced to be reduced, but this prolongs the plating process, even to unacceptable levels. Shorter plating times became a reality with the advent of reverse pulse rectifiers and chemistries suited to the plating process. [0004] However, because the module of the pulse rectifier takes up a lot of space, the pulse rectifier is generally placed next to the electrolyte tank when it is arra...
