It is widely used in highly reliable metal/ceramic shell packaging technology.Its principle are as follows: assembly is with weldering in shell sealing
Expect the cover board of ring, and high temperature resistant clip will be used to carry out stable holding between cover board and shell, then in nitrogen protection atmosphere
Being heated to gold-tin alloy fusing point or more makes gold-tin eutectic solder melting, is fused into the seal mouth ring of the solder infiltration shell of liquid
Metal layer and cover board welding surface after reaching soaking time, naturally cool to fusing point hereinafter, will by solder and intermetallic compound
Pedestal and cover board, which weld together, completes alloy sealing cap.Its non-obforms assembling schematic diagram is as shown in Figure 1, alloy sealing cap includes protection
Silicon cover board 16, metal cover board 17, solder ring 18, ceramic base 19 and shell outer lead 20.
Before alloy sealing cap, the cover board with solder ring must be carried out with shell sealing ring by the method for hand assembled
Assembly is clamped after accurate contraposition, or clamps assembly after cover board, the solder ring of separation, shell are carried out exactitude position one by one, herein
In the process, because of the level of skill of operator, the difference of naked eyes aligning accuracy easily leads to contraposition offset (such as cover board and solder
Ring offset, cover board and shell offset, solder ring and shell offset, the cover board/solder ring/same hour offset of shell), in subsequent sealing cap
In the process, a series of problems, such as to cause solder to scatter bad, and sealing ring is discontinuous, and solder overflows lid, sealing cap gas leakage.And clip
Also metal cover board surface may be caused to damage, causes that appearance is unqualified and salt spray test is unqualified.
Summary of the invention
For above-mentioned problem, the utility model proposes a kind of obforms assembly method of alloy sealing cap and its assembling jig,
The assembling jig includes assembling jig main body 1, the multiple groove 2 of spaced set in assembling jig main body 1, around groove 2
It is provided with step 3, the side of assembling jig main body is provided with fluting 4, when sealing shelf protrudes into fluting 4, seals the end of shelf
Head is placed exactly in the center of groove 2.
Further, the size of the groove 2 is matched with the protection silicon cover board and metal cover board of sealing cap, the size of step 3
It is matched with ceramic shell.
Further, depth of groove 8 is 1.5mm, and step depth 9 is 2.16mm.
Further, assembling jig main body 1 with a thickness of 10mm.
Further, assembling jig main body 1 is stainless steel material.
Preferably, the width for sealing clip 14 is no more than 4mm.
Invention realizes the automatic aligning at assembling process cover plate edge Yu shell sealing ring by Fixture designing,
Especially for the cover board occasion isolated with solder ring itself, self-aligning advantage can be more embodied；It is filled using the fixture
Timing, assembly efficiency is high, and aligning accuracy is accurate, effectively prevents the cover board displacement in assembling process, and because sealing caused by displacement
Fill leakage problem；Packaging clip sub-folder, which is held, is a little located at cover plate central, is uniformly distributed chucking power on the cover board.Actual design production
Tens kinds of shell special metals sealing cap obforms assembling jigs, it is total to be used in more than 50,000 formal product, seal yield rate 99.5%
More than, the problems such as unqualified problem of air-tightness caused by no cover board deviates or metal cover board scratch.
