Portion is filled with nitrogen with 30ml/min speed；
Step 3, the conveyer belt being put into the graphite Noah's ark on soldering oven, pass through conveyer belt and drive graphite Noah's ark to carry out pricker
Weldering, soldering oven is taken out of after soldering.
Further, the graphite Noah's ark includes graphite boat body, and the graphite boat body is provided with entrance point and gone out
Mouth end, the entrance point is relative with the port of export, and plural number is symmetrically arranged with the entrance point and the port of export of the graphite boat body
Individual jut, and air port is provided between the adjacent protrusions, the graphite boat body is provided with a plurality of graphite boat pieces, each
The graphite boat piece is provided with plurality of receptacles, and the jack is arranged in the graphite boat piece both sides, the air port width respectively
Less than the minimum range between the jack of the graphite boat piece both sides, at least one keep out the wind is provided between described two relative air ports
Portion, the graphite boat piece are respectively arranged between the windshied part and air port, or the graphite boat piece located at the windshied part with
Between windshied part.
Further, each graphite boat piece is detachably located on the graphite boat body.
Further, each graphite boat piece two sides are respectively equipped with fixed part, and the fixed part is located at the graphite
On boat body.
Further, the length of the fixed part is less than the length of the graphite boat piece.
Further, the width of the windshied part is equal to the width in the air port.
Further, each graphite boat piece is provided with a mark part.
The invention has the advantages that：A kind of ceramic package method for welding of the present invention so that on for ceramic package soldering
It is not easy to be oxidized during pin so that it produces qualification rate and greatly increased, and in process of production ceramic package is heated
Uniformly, be not in that the frame that cuts down on ceramic package is upwarped due to uneven heating.
Brief description of the drawings
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the top view of the graphite boat in a kind of ceramic package method for welding of invention.
Embodiment
Ceramic package method for welding of the present invention, methods described need to provide a kind of graphite Noah's ark, specifically comprise the following steps：
Ceramic package, is positioned on graphite Noah's ark by step 1, the jack for inserting pin in graphite Noah's ark afterwards；
Step 2, being sealed up a door with 60ml/min speed toward the entrance of soldering oven is filled with nitrogen, and in the burner hearth of soldering oven
Portion is filled with nitrogen with 30ml/min speed；The nitrogen flow for sealing up a door out from the outlet of soldering oven is also 60ml/min, wherein
Entrance is sealed up a door and outlet closure door flow is exactly burner and stove tail nitrogen flow, and nitrogen is entered in this place primarily to isolation burner hearth
With the external world, avoiding the air oxygen in the external world from entering burner hearth causes to aoxidize.And enter nitrogen in burner hearth centre position, ensure in burner hearth
It is malleation, like this, the gas only in burner hearth can slowly escape through outward, but extraneous oxygen can enter burner hearth, just rise
The effect of protection has been arrived, and has taken away a part of heat in soldering oven；
Step 3, the conveyer belt being put into the graphite Noah's ark on soldering oven, pass through conveyer belt and drive graphite Noah's ark to carry out pricker
Weldering, soldering oven is taken out of after soldering.
Refer to shown in Fig. 1, graphite Noah's ark of the present invention, including graphite boat body 1, the graphite boat body 1 be provided with into
Mouthful end 11 and the port of export 12, the entrance point 11 is relative with the port of export 12, the entrance point 11 of the graphite boat body 1 and goes out
