The embodiment of the present application provides a shielding plate, which will be described in detail below.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a shielding plate according to an embodiment of the present application. The shield plate 100 may include a main body portion 10, an attaching portion 20, and a hooking portion 30.
Wherein the body portion comprises a first side 11, a second side 12, a third side 13 and a fourth side 14. The first side 11 and the second side 12 are oppositely disposed, and the third side 13 and the fourth side 14 are oppositely disposed. The first side 11 and the second side 12 are connected between the third side 13 and the fourth side 14, respectively.
The attaching portion 20 is disposed on the first side 11 of the main body 10. The bonded portion 20 extends in a direction away from the main body portion 10.
The hooking portion 30 includes a first extending portion 31 and a second extending portion 32. The first extending portion 31 is disposed on the third side 13, and the first extending portion 13 extends in a direction away from the main body 10. The second extension 32 is connected to the first extension 31, and the second extension 31 extends in a direction toward the attachment portion 20. And, a gap 301 is formed between the second extending portion 32 and the third side 13.
In some embodiments, the body portion 10 includes a first surface 15 and a second surface 16. The attaching portion 20 includes a first attaching sub-portion 21 and a second attaching sub-portion 22.
The first attaching sub-portion 21 is flush with the second surface 16, and the second attaching sub-portion 22 is flush with the first surface 15. The thickness of the first bonded sub-section 21 is half of the thickness of the main body section 10. The thickness of the second attached sub-portion 22 is half of the thickness of the main body portion 10.
It is understood that the first sub-attaching portion 21 has the same size as the second sub-attaching portion 22.
The shielding plate 100 provided by the embodiment of the application is used in pairs, and the attaching part 20 of the shielding plate 100 is arranged to be in the symmetrical opposite-inserting structure of the embodiment, so that the operation of an operator can be facilitated, and the phenomenon that the shielding area is poor due to the wrong installation of the shielding plate 100 is avoided. In addition, the shielding plate 100 of the above embodiment, which adopts the symmetrical opposite insertion structure, has good versatility and is suitable for products of the same size.
In actual operation, when the shielding plate 100 is used in a gold plating tank, the electroplating jig uses a swing mechanism, and the shielding plate 100 continuously swings back and forth and left and right due to low density, so that the gold plating thickness in the shielding area is not uniform, and poor problems such as color difference and obvious boundary are caused.
In some embodiments, in order to avoid the above-mentioned problem when the shielding plate 100 is used in the gold plating groove, a magic tape may be disposed on the side of the first attaching sub-portion 21 facing the first surface 15. The second attaching sub-portion 22 is provided with a hook and loop fastener facing to the second surface 16. When the two shielding plates 100 are used in cooperation, it is difficult to separate the two shielding plates 100 without an external force.
As described above, when the two shielding plates 100 are used in combination, the mass of the shielding plates 100 is increased to some extent, and the shielding plates 100 immersed in the plating solution are prevented from being shaken back and forth and left and right, thereby preventing the above-described problem from occurring in the shielding region.
In some embodiments, the second extension 31 of the hooking portion 30 has several adjacent grooves 301 on a side thereof close to the third side 13 of the main body 10. The groove 301 is used for matching with an electroplating fixture during gold plating operation, so as to prevent the shielding plate 100 from falling off due to swinging of the electroplating fixture.
In the embodiment of the present application, the material of the shielding plate 100 is an insulating material. The insulating material has hydrophobic properties. It is understood that the use of the insulating material having hydrophobic property facilitates the removal of the plating solution remaining on the shielding plate 100 in a short time when the shielding plate 100 is taken out from the gold plating bath, thereby preventing the surface of the shielding plate 100 from being attached with the plating solution during the use.
The insulating material has a certain heat resistance. For example, the insulating material may work at a temperature in the range of 90 degrees celsius without deformation, thereby avoiding non-uniform thickness of the gold plating layer due to deformation of the shielding plate 100.
In some embodiments, the first surface 15 and the second surface 16 of the body portion 10 are smooth to avoid scratching the surface of the semiconductor laser package.
In addition, during the use of the shielding plate 100, the shielding plate 100 is close to the bottom surface of the semiconductor laser package, and the shielding plate 100 is inserted too long from the left-right direction. In the operation process, the edge of the shielding plate 100 is cut and rubbed on the semiconductor laser tube shell, so that bright prints and scratches are formed on the surface of the semiconductor laser tube shell after the edge is cut and rubbed, and the attractiveness of the semiconductor laser tube shell is affected.
In some embodiments, the outward corners of the shielding plate 100 may be all configured as rounded structures, so as to prevent edges and corners of the shielding plate 100 from scratching the semiconductor laser tube shell.
In summary, the shielding plate 100 provided in the embodiment of the present application, through the shielding effect, makes the current density of the shielded portion on the bottom surface of the semiconductor laser package not reach the limit current density necessary for the gold plating layer to precipitate, so that when the gold plating operation is performed on the bottom surface of the semiconductor laser package, at most, the shielded portion can be plated with only one gold plating layer, thereby reducing the thickness of the gold plating layer on the bottom surface of the semiconductor laser package, and further reducing the manufacturing cost of the semiconductor laser.
The shielding plate provided by the embodiment of the present application is described in detail above, and the principle and the implementation of the present application are explained in the present application by applying a specific example, and the description of the above embodiment is only used to help understand the core idea of the present application; meanwhile, for those skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
