Embodiment Construction

[0022] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0023] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

Abstract

The invention discloses a single bridge wire frame deburring process, which comprises a preliminary molding step, namely, putting a copper sheet to be molded into a mold for extrusion to obtain a pre-fabricated product; a heating step, namely, putting the prefabricated product into an oven for heating to obtain a pre-heated product; a cold treatment step, namely, putting the preheated product intoa cold box to obtain a pre-molded product; an acid pickling process, namely, putting the pre-molded product into an acid pickling solution for acid pickling; and a deburring step, namely, carrying out deburring treatment on the acid pickled product. The burr part of the copper sheet to be molded is enabled to be brittle through carrying out heat and cold treatment alternately, the pretreatment iscarried out through acid pickling, and then burrs are removed. The single bridge wire frame deburring process is good in deburring effect, small in residual quantity and high in removal efficiency.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a single bridge wire frame deburring process. Background technique [0002] At present, the rectifier bridge stack product is made of four rectifier silicon chips for bridge connection and externally packaged with insulating plastic. The high-power rectifier bridge is encapsulated with a zinc metal shell outside the insulating layer to enhance heat dissipation. [0003] A bridge stack is an electronic component that consists of multiple diodes inside. Schematic diagram of the bridge stack The main function of the schematic diagram of the bridge stack is to rectify and adjust the direction of the current. It is better to rectify with a bridge stack, first of all, it is very convenient, and the four tubes inside it are generally selected and paired, so its performance is relatively close, and when the rectification is high-power, the bridge stack can be installed with a cooling block S...
