[0035] In some embodiments, the device-avoiding slot 201 has a rectangular cross section perpendicular to the thickness direction, i.e. a square or a rectangle.

[0036] The cross-sectional dimensions of the device-avoiding slots 201 of different types of attached assembly parts are different, and the dimensions of at least one corresponding direction of the cross sections of the device-avoiding slots 201 of different types of attached assembly parts are different. Taking the shape of the device-avoiding slot 201 as a square as an example, the side length of the device-avoiding slot 201 of different types of attached assembly parts is different, such as Figure 6 The side length d1 of the cross section of the device-avoiding slot 201 perpendicular to the thickness direction is different from Figure 8 The side length d2 of the cross section of the device-avoiding slot 201 perpendicular to the thickness direction is different from

[0037] It should be noted that the cross section of the assembly slot 101 perpendicular to the thickness direction T can also have other shapes. The cross section of the device-avoiding slot 201 perpendicular to the thickness direction can also have other shapes.

[0038] In some embodiments, the shapes and dimensions of the cross sections perpendicular to the thickness direction T of different types of attached assembly parts are the same, so that different types of attached assembly parts can be assembled on the corresponding assembly slot 101 of the attached plate body 10 in a replaceable manner.

[0039] For example, as shown in Figure 6 The cross section of the attached assembly part 20 and the cross section of the attached assembly part 20' perpendicular to the thickness direction are the same in shape and size. Figure 8

[0040] Taking the shape of the cross section of the assembly slot 101 perpendicular to the thickness direction T as a square as an example, the cross section of the attached assembly part 20 and the cross section of the attached assembly part 20' perpendicular to the thickness direction are adapted squares, and the side lengths D1 and D2 of the cross sections of the attached assembly part 20 and the attached assembly part 20' perpendicular to the thickness direction are equal. In some embodiments, the thickness of each attached assembly part is the same as the depth of the corresponding assembly slot 101, so that when the attached assembly part is arranged in the assembly slot 101, the back surface of the attached assembly part can be flush with the first surface S11 of the attached plate body 10, so that the attached plate body 10 can well support the lead frame edge of the packaging pre-sequence module.

[0041] For example, as shown in Figure 3 The thickness t of the attached assembly part 20 is the same as the depth h of the assembly slot 101. The thickness (not shown) of the attached assembly part 20' is also the same as the depth h of the assembly slot 101. ​

[0055] The attaching plate body 10 has a second surface S12 opposite to the first surface S11, and the vacuum suction hole 104 penetrates the first surface S11 and the second surface S12.

[0056] In some embodiments, when a plurality of concave assembly grooves 101 are provided in the assembly functional area S111, the plurality of concave assembly grooves 101 are arranged at intervals along the length direction L of the film attaching attaching plate, as Figure 4 illustrated.

[0057] Of course, in other embodiments, the plurality of assembly grooves 101 can also be arranged at intervals according to needs.

[0058] In combination with Figure 4 and Figure 5 illustrated, the thickness of the area of the attaching plate body 10 except the assembly groove 101 is uniform. In some embodiments, the plurality of assembly grooves 101 have a spacing area 105 therebetween. The first surface S11 can also have a peripheral area S113 located at the periphery of the lead frame edge support area S112. The peripheral area S113 and the spacing area 105 can be provided with an attaching plate body mounting hole 106, which is used to mount and fix the attaching plate body 10 on a corresponding back film attaching machine.

[0059] It should be noted that the inventors have found through research that, in some embodiments, for the attaching plate for the film has multiple types of attaching fittings, the cost can even be saved by more than 70%.
