Problems solved by technology

[0003] In this method, the insulating sheet has to be punched through the dots, which is troublesome to make. When using it, it has to be torn and pasted in two parts. The operation is troublesome, and the production and use are not fast. The attachment accuracy is greatly reduced, the attachment position cannot be well matched, and displacement deviation is prone to occur, which affects subsequent use

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, an insulating sheet made by a stretching die includes an insulating sheet body 1 and a release paper 2, an adhesive layer is arranged on the back of the insulating sheet body 1, and the release paper 2 is attached to the insulating sheet through the adhesive layer Body 1 back. The insulating sheet body 1 is stretched out from the back to the front by stretching a number of arc-shaped dots 3, and the set arc-shaped dots 3 correspond to the protruding positions of the circuit board welding points one by one, and the arc-shaped dots The edge of 3 is connected to the insulating sheet body 1, and the height of the arc-shaped dot 3 is higher than the height of the plane of the insulating sheet body 1. The arc-shaped dots 3 can wrap the solder joint protrusions on the circuit board.

[0014] In summary, the present invention is an insulati...

Abstract

The invention discloses an insulating strip manufactured through a drawing die. The insulating strip manufactured through the drawing die comprises an insulating strip body and release paper. The insulating strip manufactured through the drawing die is characterized in that a glue layer is arranged on the back face of the insulating strip body, and the release paper is attached to the back face of the insulating strip body through the glue layer. Arc round points corresponding to welding point protrusions of a circuit board in position are formed in the front face of the insulating strip body, the edges of the arc round points are connected with the insulating strip body, and the height of the arc round points is larger that that of the plane of the insulating strip body. According to the insulating strip manufactured through the drawing die, the drawing die is adopted to draw a convex-concave structure which are at the round point positions and are matched with the welding point protrusions on the circuit board at a time, one-time forming and one-time attaching are adopted, the machining efficiency and the machining speed are greatly improved, and attaching accuracy is ensured.

Description

technical field [0001] The invention relates to a concave-convex mold, in particular to an insulating sheet made by a stretching mold. Background technique [0002] Insulating sheet is the general term for electrical insulating paper, which is used as insulating material for various electrical equipment such as cables and coils. The back of the insulating sheet is often provided with a release paper, which is torn off during use, and then attached to the corresponding equipment for use. In the process of circuit board processing, an insulating sheet needs to be provided on the back of the circuit board, and the back of the circuit board often has solder joint protrusions. In the past, in order to avoid the solder joint protrusions on these circuit boards, during the punching process In the process, the dots on the insulating sheet will be punched and broken, and the remaining insulating sheet will be torn off the release paper and pasted on the circuit board, and then the p...
