Abstract
The utility model discloses a kind of thin space eutectic weldering suction nozzle being applicable to have protrusion bonding to refer in shell, comprise suction nozzle, described suction nozzle is used for welding with shell eutectic, it is characterized in that, the side bottom described suction nozzle is provided with breach; Described shell inside is provided with protruding bonding and refers to; The width of described breach is greater than the width that bonding refers to.The beneficial effect that the utility model reaches: suction nozzle side is jagged, breach can on both sides or, design as required, there is selectivity, versatile and flexible.Than being easier to operating key conjunction, suction nozzle, when gripping part, refers to that raised brim arrives the distance of part edge.This nozzle structure simplicity of design, easy to use on chip mounter, the thin space eutectic Welding that shell bonding in paster refers to raised brim and part edge can well be solved.
Description
Technical field
The utility model relates to a kind of thin space eutectic weldering suction nozzle being applicable to have protrusion bonding to refer in shell, belongs to Radar-Communication device packaging technique field.
Background technology
Microwave power device is widely used in communication system and radar system.About the inductance of lead-in wire and electric capacity directly have influence on the performance of circuit in the design of microwave device, and one of approach controlling inductance is exactly length and the height of lead-in wire, control lead-in wire length need the position of part in control circuit, when part needs the bonding in shell to refer to, common suction nozzle is just difficult to control so little gap.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of thin space eutectic weldering suction nozzle being applicable to have protrusion bonding to refer in shell that can reach the even less gap of 0.05mm.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
Be applicable to have in shell the thin space eutectic weldering suction nozzle protruding bonding and refer to, comprise suction nozzle, described suction nozzle is used for welding with shell eutectic, it is characterized in that, the side bottom described suction nozzle is provided with breach; Described shell inside is provided with protruding bonding and refers to; The width of described breach is greater than the width that bonding refers to.
Aforesaid a kind of thin space eutectic weldering suction nozzle being applicable to have protrusion bonding to refer in shell, is characterized in that, be provided with microwave part to be welded in described shell; The height that described bonding refers to is greater than the thickness of microwave part to be welded; The degree of depth of described breach equals the distance from the side bottom suction nozzle to microwave part edge to be welded.
Aforesaid a kind of thin space eutectic weldering suction nozzle being applicable to have protrusion bonding to refer in shell, it is characterized in that, described breach is arranged on side or both sides.
The beneficial effect that the utility model reaches: suction nozzle side is jagged, breach can on both sides or, design as required, there is selectivity, versatile and flexible.Than being easier to operating key conjunction, suction nozzle, when gripping part, refers to that raised brim arrives the distance of part edge.This nozzle structure simplicity of design, easy to use on chip mounter, the thin space eutectic Welding that shell bonding in paster refers to raised brim and part edge can well be solved.
Accompanying drawing explanation
Fig. 1 is the structural representation of suction nozzle;
Fig. 2 is the cross section structure schematic diagram of suction nozzle;
Fig. 3 is the bottom surface structure schematic diagram of suction nozzle;
Fig. 4 is the vertical view of shell;
Fig. 5 is the cross section structure schematic diagram of shell.
The implication of Reference numeral in figure:
1-microwave shell, 2-microwave part to be welded, 3-bonding refers to, 4-suction nozzle, 5-suction nozzle endoporus, 6-breach.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.
A kind of thin space eutectic weldering suction nozzle 4 being applicable to have protrusion bonding to refer to 3 in shell of the utility model design.As Fig. 1, the side bottom suction nozzle 4 is provided with breach 6, breach 6 is arranged on wherein side or both sides, can design as required.
The bonding being provided with microwave part 2 to be welded and projection in shell refers to 3.
Suction nozzle 4 is when gripping part, in order to refer to the distance of 3 raised brim to part edge than being easier to operating key conjunction, the width of breach 6 is greater than the width that bonding refers to 3, bonding refers to that the height of 3 is greater than the thickness of microwave part 2 to be welded, the degree of depth D of breach 6 equals the distance (as Fig. 3) from the side bottom suction nozzle 4 to microwave part 2 to be welded edge, so in welding process, microwave part 2 to be welded edge more can refer to 3 edges near bonding, and the weldering of paster eutectic can control less gap.Meet the thin space requirement of microwave components design needs.
In prior art, about the inductance of lead-in wire and electric capacity directly have influence on the performance of circuit in the design of microwave device, and one of approach controlling inductance is exactly length and the height of lead-in wire, control lead-in wire length need the position of part in control circuit, when part needs the bonding in shell to refer to 3, common suction nozzle 4 is just difficult to control so little gap.On conventional suction nozzle 4, adopt this programme to carry out design suction nozzle 4, the gap that 0.05mm is even less can be reached, like this for the design of microwave circuit brings very large convenience.Wherein the design of breach 6 is to refer to that 3 reserve enough spaces to the bonding of shell, comprises on height and distance in the degree of depth, better can realize bonding like this and refer to that 3 raised brim are welded to the thin space eutectic of part edge.On conventional suction nozzle 4, adopt new departure to carry out design suction nozzle 4, the gap that 0.05mm is even less can be reached, like this for the design of microwave circuit brings very large convenience.Wherein the design of breach 6 is to refer to that 3 reserve enough spaces to the bonding of shell, comprises on height and distance in the degree of depth, better can realize bonding like this and refer to that 3 raised brim are welded to the thin space eutectic of part edge.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection range of the present utility model.
