DETAILED DESCRIPTION

[0024] The application will be further described in detail below with reference to the accompanying drawings.

[0025] Figure 1 The first cutting of the electromagnetic shielding material roll cutting process according to an embodiment of the application is schematically shown, wherein (a) is a top view and (b) is a front view; Figure 2 The second cutting of the electromagnetic shielding material roll cutting process in Figure 1 is shown, wherein (a) is a top view and (b) is a front view, Figure 3 The third cutting of the electromagnetic shielding material roll cutting process in Figure 1 is shown, wherein (a) is a top view and (b) is a front view, Figure 4 The top view structure of the product finished product of the electromagnetic shielding material roll cutting process in Figure 1 is shown.

[0026] The electromagnetic shielding material 5 roll cutting process includes several main steps, which are described below.

[0027] First, the product area is formed and outer-shielded.

[0028] In this step, first, the first release film 2 is attached to the first protective film 1, and the product area is formed. Then the product area is outer-shielded according to the size of the drawing, and the outer-shielded size is preferably 0.2mm.

[0029] Second, the first cutting is performed.

[0030] As shown in Figure 1 , the first cutting needs to be cut in two places respectively. The first place is to cut a plurality of positioning holes 3 on the edge of the first protective film 1 to facilitate positioning for subsequent cutting work; the second place is to cut the outer-shielded product area on the first release film 2 to have a general product shape, which is called an outer-shielded product 4.

[0031] After the first cutting is completed, the waste generated by the cutting is removed.

[0032] Third, the electromagnetic shielding material 5 and the second release film 6 are attached.

[0033] In this step, an electromagnetic shielding material 5 with metal wires and a second release film 6 are sequentially attached to the product 4 that is shielded on the outer side of the first release film 2.

[0034] The fourth step is to perform a second die-cut.

[0035] like Figure 2 As shown (where the vertical arrow indicates the die-cutting position), the second die-cutting requires cutting a portion of the product shape 7 onto the electromagnetic shielding material 5 according to the dimensions in the drawing, thus forming a semi-finished product.

[0036] During the second die-cutting process, the product can be fixed by using the positioning holes 3 in conjunction with positioning pins on other structures.

[0037] Step 5: Apply the third release film 8 and the second protective film 9.

[0038] In this step, the second release film 6 is first removed, and then the third release film 8 and the second protective film 9 are sequentially bonded onto the semi-finished product. The thickness of the third release film 8 is preferably 0.05 mm.

[0039] The sixth step is to perform the third die-cutting.

[0040] like Figure 3 As shown (where the vertical arrows indicate die-cutting locations), the third die-cutting requires die-cutting at two locations. The first location is die-cutting the material strip 10 onto the first release film 2 of the semi-finished product, and the second location is die-cutting another part of the product shape 11 onto the electromagnetic shielding material 5, thus forming a shape as shown. Figure 4 The product shown is finished product 12.

[0041] During the third die-cutting process, the product can also be fixed by using the positioning holes 3 in conjunction with positioning pins on other structures.

[0042] Finally, after the third die-cutting is completed, the waste material can be removed and the finished product 12 can be wound up.

[0043] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
