Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with specific embodiments.

[0014] A manufacturing process of a curved aluminum substrate, the specific steps are as follows:

[0015] Step 1: Select the mold according to the requirements, and then punch the aluminum substrate to make the mold punch into a curved shape;

[0016] Step 2: Put the punched aluminum substrate into the cold pressing device for cold pressing;

[0017] Step 3: Repeat the cold pressing of the aluminum substrate until it is flat.

[0018] The cold pressing device is a rolling mill; the rolling mill can adjust the pressure intensity; the rolling mill includes: an upper roller group and a lower roller group arranged up and down; the upper roller group and the lower roller are equipped with motors to control the upper roller group and the lower roller group. The lower roller rolls; the upper roller group is provided with a fine-tuning screw and a tension adjustment sc...

Abstract

The invention discloses a manufacturing process of a curved surface aluminum substrate, which comprises the following steps: step 1, selecting a die according to demand, and then punching the aluminumsubstrate by the die, so that the die is punched into a bending shape; step 2, putting the aluminum base plate after die punching into a cold pressing device for cold pressing; step 3, repeatedly cold-pressing the aluminum substrate for several times until the aluminum substrate is smooth. In the above manner, the process can produce a curved aluminum substrate, level the curved aluminum substrate, and improve the quality of PCBs.

Description

technical field [0001] The invention relates to an improvement of a manufacturing process of a curved aluminum substrate, in particular to a manufacturing process of a curved aluminum substrate capable of making a curved aluminum substrate and making the curved aluminum substrate smooth so as to improve the quality of a PCB. Background technique [0002] PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board; when a curved PCB board is required, the traditional milling machine cannot be milled because there is no positioning in the board. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a manufacturing process of the curved aluminum substra...
