Description

Technical Field

[0001] The utility model relates to a ceramic packaging shell, in particular to a ceramic shell. Background Art

[0002] After sintering, the existing ceramic shell needs to have its pins brazed to the pads of the ceramic shell. In the existing technology, the pads of the ceramic shell are on the same plane as the ceramic part. During brazing, the ceramic shell is placed on a graphite boat, and then a whole piece of solder and the pins are placed on the ceramic shell. Then, the lid of the graphite boat is covered and the shell is placed in a brazing furnace for brazing. During the brazing process, the solder will stretch out, forming a situation where it is thick in the middle and thin at the edges, making the solder uneven. This results in uneven strength of the pins of the ceramic shell, and some pins are not strong enough to pass quality inspection. In addition, the uneven solder makes the appearance of the ceramic shell very ugly, which is not conducive to product sales. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a ceramic housing so that the solder is uniform and the pin strength meets the quality inspection requirements.

[0004] The utility model is implemented as follows: a ceramic shell comprises a plurality of pins and a ceramic shell body, the ceramic shell body is provided with a plurality of grooves, one side of each of the grooves is provided with an opening; the bottom of the groove is a pad, the pins are connected to the pads in a one-to-one correspondence, and the width of the groove is greater than the width of the pins.

[0005] Furthermore, the depth of the groove is greater than the thickness of the pin.

[0006] The advantages of the utility model are as follows: the utility model provides a ceramic shell with a soldering pad having a groove, so that the solder can be evenly spread in the groove and fill the groove, the pin is firmly fixed, and the yield of the product is greatly increased; and because the solder is evenly spread, the appearance of the ceramic shell is more beautiful, which is conducive to the sales of the product; and because of the presence of the groove, one side of the pin of the ceramic shell has no protrusions on the plane, which is conducive to user use. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The present invention will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

[0008] Figure 1 It is a schematic diagram of a ceramic shell of the utility model.
