Description
Technical field
The utility model belongs to Electronic Assemblies field, the small-size chips carrier (<4mm particularly in a kind of microwave components
2) frock that uses in eutectic welding sequence.
Background technology
There is a large amount of gallium arsenide chips in microwave components, generally realized the interconnection of gallium arsenide chips and carrier by eutectic welding.At present, the equipment of eutectic welding has manual eutectic welding machine and eutectic brazier two class.Wherein, manual eutectic bonding machine because of be applicable to small lot, low cost and other advantages application comparatively extensive.
Manual eutectic bonding machine adopts vacuum slot, and utilize the roughness of chip carrier to be fixed on warm table by chip carrier, larger chip carrier is more easily fixed.But eutectic welding need be carried out in cleaning shop, and air feed equipment is generally outside cleaning shop, and therefore the laying of circuit is longer; And need in cleaning shop to use the equipment of vacuum to have a lot, make the pull of vacuum of manual eutectic bonding machine can not meet the fixing of small-size chips carrier, facts have proved chip carrier area <4mm. simultaneously
2time pull of vacuum be difficult to fixed chip carrier well, small-size chips carrier area all <4mm of following indication
2.Therefore current, manual eutectic bonding machine is applicable to size (>4mm bigger than normal
2) chip carrier eutectic welding, reduced size chip carrier can only be welded by eutectic brazier, and cost is higher.
Utility model content
In view of the above problems, applicant, through Improvement, provides one to be applicable to area <4mm
2all chip carriers microwave components in small-size chips carrier eutectic welding tooling.
The technical solution of the utility model is as follows:
Small-size chips carrier eutectic welding tooling in a kind of microwave components, comprise for carrying, the eutectic jig of positioning chip carrier, for one-level slide block and the secondary slide block of positioning chip carrier, fix the fixed head of described one-level slide block and secondary slide block for vertical direction; Described eutectic jig there is the chute along long side direction, can be free to slide along the chute of long side direction relative to eutectic jig in the chute that described one-level slide block and secondary slide block are in described long side direction, described fixed head and one-level slide block are contacted with the end face of secondary slide block and are fixed by screw and eutectic jig.
Its further technical scheme is: described secondary slide block is provided with spring screw, and described secondary slide block is fixed on the sidewall of eutectic jig by spring screw, and described secondary slide block abuts with one-level slide block elasticity.
And its further technical scheme is: the tungsten-copper alloy of described one-level slide block to be thickness be 0.18mm.
Advantageous Effects of the present utility model is:
The utility model achieves the welding of small-size chips carrier on manual eutectic bonding machine, solves the problem using manual eutectic bonding machine pull of vacuum deficiency, compared to the welding of use eutectic brazier, has saved cost, easy to operate, applicability is strong.

Fig. 1 is structure chart of the present utility model.
Description of reference numerals: 1, eutectic jig; 2, one-level slide block; 3, secondary slide block; 4, spring screw; 5, fixed head; 6, chip carrier.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Figure 1, the utility model primarily of for carrying, the eutectic jig 1 of positioning chip carrier 6, for the one-level slide block 2 of positioning chip carrier 6 and secondary slide block 3 and the fixed head 5 three part composition for fixing one-level slide block 2 and secondary slide block 3 in the vertical direction.
Eutectic jig 1 is monosymmetric structure, its both sides can use simultaneously, there is 4 screwing through hole and 1 long side direction along eutectic jig 1 and to arrange and can monolateral spacing horizontal concrete chute in the surface of both sides, the side of eutectic jig 1 exists 1 screw respectively respectively.4 screwing through hole of eutectic jig 1 side can with the docking of warm table, remaining side is then for chip carrier 6.When using pull of vacuum to fix eutectic jig 1, two chip carriers 6 can be installed in the both sides of eutectic jig 1 simultaneously.
One-level slide block 2 is placed in the chute of eutectic jig 1, and for clamping chip carrier 6, it is the tungsten-copper alloy sheet of 0.18mm, and hardness is high, wearability good, directly can contact with chip carrier 6.Secondary slide block 3 is brass material, and machinability is better, and it is fixed on the sidewall of eutectic jig 1 by spring screw 4, makes it have certain elastic thrust to one-level slide block 2.One-level slide block 2 and secondary slide block 3 all can be free to slide along the chute of long side direction relative to eutectic jig 1.The height of one-level slide block 2 and secondary slide block 3 can be different.
Fixed head 5 has two pieces, cover respectively above one-level slide block 2 and secondary slide block 3, and use the screw of different length to be fixed in the screwing through hole of eutectic jig 1, carry out spacing to the vertical direction of one-level slide block 2 and secondary slide block 3 respectively, one-level slide block 2 and secondary slide block 3 only can be moved in the chute of eutectic jig 1.
Fig. 1 is the schematic diagram after the small-size chips carrier of certain microwave components is installed to the utility model frock.The utility model is applicable to the eutectic welding of polytypic small-size chips carrier, use step is: first use cross to rise and unscrewed by spring screw 4, tweezers are used to stir one-level slide block 2 according to the single side size of small-size chips carrier 6, small-size chips carrier 6 to be welded is placed on eutectic jig 1, recycling cross rises and is screwed by spring screw 4, make secondary slide block 3 pairs of one-level slide block 2 applied thrusts, thus fixing small-size chips carrier 6.Then four screwing through hole of eutectic jig 1 opposite side or vacuum slot is utilized to be fixed on manual eutectic bonding machine by eutectic jig 1.The manual eutectic bonding machine of last operation completes eutectic welding.
Above-described is only preferred embodiment of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite not departing from spirit of the present utility model and design, all should think and be included within protection domain of the present utility model.
