Abstract
The utility model relates to a SMD seating, comprising a base plate, a piece of shrapnel and an insulating object; wherein, the shrapnel is fixed by the insulating object and the base plate. The utility model is characterized in that the insulating object is made of glass, and the rim of the base plate is provided with external margin. As the insulating object is made of glass, and the rim of the base plate is provided with external margin, when in the processing of the SAM seating, the producer of 49 U/S and UM seating is unnecessary to exchange the sintering apparatus; the sintering apparatus of 49 U/S glass can also insulate the shrapnel and are connected with the base plate; during the manufacturing of the SMD crystal, the operator can just need to place quartz crystal chip inside the SMD seating, and then seal the device and the shell with 49 U/S crystals; no need to add an expensive sealing device; therefore, the apparatus amount and the cost are greatly reduced, with good competitive capability in the market.
Description
Affiliated technical field
The utility model provides a kind of surface mount SMD pedestal, belongs to technical field of electronic components.
Background technology
Along with people's living standard improving constantly to the electronic product demand, relevant electronic product manufacturer uses the SMT surface mounting technology to improve product quality and production efficiency on a large scale, SMT increases the type requirements that mounts electronic devices and components, the SMD crystal is corresponding to become the product that replaces common crystal, and the surface mount SMD pedestal main raw material(s) of SMD crystal just.The surface mount SMD pedestal of external existing moulding is made up of base plate, shell fragment and ceramics insulator three parts, with above-mentioned three kinds of raw material graphite jig of packing into, by 1300 ℃～1400 ℃ high temperature sintering, is surface mount SMD pedestal after the cooling.Because about 1200 ℃ of the highest sintering temperature of domestic common producer agglomerating plant, and when making the SMD crystal with this surface mount SMD pedestal, quartz crystal slice need be put into surface mount SMD pedestal, attached again with shrouding, with special press packing equipment three's roll-welding is connected together, this press packing equipment costs an arm and a leg, increased the cost of SMD crystal so virtually, price is higher, and its manufacture craft is more complicated also, is difficult to realize production domesticization.
The utility model content
The purpose of this utility model provides a kind ofly can overcome above-mentioned defective, manufacture craft is simple, cost is low, make domestic pedestal manufacturer at investment goods not, do not change under the situation of knot equipment with regard to fertile surface mount SMD pedestal.Its technical scheme is:
Comprise base plate, shell fragment and insulator, wherein shell fragment is isolated by insulator and fixedlyed connected with base plate, it is characterized in that: insulator adopts glass insulator, and the periphery of base plate is provided with the outer.
Described surface mount SMD pedestal, the opposite ends of base plate is respectively arranged with slot, and the shell fragment correspondence is inserted in the slot, and is isolated fixing by glass insulator.
Because insulator of the present utility model adopts glass insulator, periphery at base plate is provided with the outer, so when making surface mount SMD pedestal, can make domestic production 49U/S, the manufacturer of UM series pedestal need not change agglomerating plant, use 49U/S glass sintering equipment shell fragment can be isolated and fixedly connected with base plate, when making the SMD crystal, need only and in surface mount SMD pedestal, load onto quartz crystal slice, use 49U/S crystal press packing equipment and shell press seal to get up to get final product, and needn't put expensive sealing device in addition, so just significantly reduced equipment, reduced manufacturing cost, made this product on market, have more certain competitiveness.
Description of drawings
Fig. 1 is the vertical view of the utility model embodiment;
Fig. 2 is an A-A profile embodiment illustrated in fig. 1.
Embodiment
1, base plate 2, shell fragment 3, insulator 4, outer 5, slot
Insulator 3 adopts glass insulators, and the opposite ends of base plate 1 is respectively arranged with slot 5, and shell fragment 2 correspondences are inserted in the slot 5, and is isolated fixingly by glass insulator 3, is provided with outer 4 at the periphery of base plate 1.
The punch process technology of China improves constantly at present, equipment is superior, can produce the stamping parts base plate that has the outer fully, domestic production 49U/S, the technology of UM series pedestal is ripe, insulating material also is a glass insulator, therefore domestic pedestal manufacturer is at investment goods not, do not change under the situation of knot equipment and just possess the sintered glass insulator, make the ability of glass insulator surface mount SMD pedestal, make its production domesticization, when making the SMD crystal, need only and in surface mount SMD pedestal, load onto quartz crystal slice, use 49U/S crystal press packing equipment and shell press seal to get up to get final product, cost is low, and competitiveness is strong.
