Abstract
The utility model relates to ageing testing devices for microelectronic components, in particular to a socket, which can be used for high-temperature ageing and reliability sorting and performance testing of 64-wire 0.5-ptch ceramic quad flat packaged components. According to structural design and dimensional requirements of a 64-wire 0.5-ptch ceramic quad flat package type, the socket comprises a socket body, a contactor and a positioning device. The socket body is composed of a seat, a cover and a hook, and functions as a pressing device, and when a component to be tested is mounted on a positioning plate and the hook is stressed to turn downwards to be meshed with the seat, the cover and pressure blocks move down to lead the tested component to tightly press the contactor. The contactor corresponds to an outgoing line of the tested component and is composed in a central symmetry and peripheral arrangement form. The positioning device is composed of the positioning plate and the pressure blocks.
Description
Technical field
The utility model relates to a kind of microelectronic component ageing tester, is the socket that can carry out high temperature ageing screening test and performance test to 64 line 0.5mm pitches potteries, four limits lead-in wire flat packaging component reliability; The utility model belongs to electronic information technology microelectronic component reliability field.
Background technology
At present, in China electronic devices and components reliability engineering field, what the bulk material of known domestic general aging test socket mostly adopted is the non-high-temperature resistant common plastics, when measured device is tested, aging working temperature only is-25 ℃～+ 85 ℃, operating time is short, the contact pitch is wide, the lead-in wire radical is few, simple in structure, exist and measured device between contact resistance is big, aging temperature is low, consistency difference and useful life are short significant deficiency, can not satisfy the quality screening of device and the test request of performance index, cause accident resulting from poor quality of projects easily.Domestic in the reliability engineering field particularly to being matched in the Shenzhou spacecraft, thrust-augmented rocket, satellite, nuclear-powered submarine, intercontinental missile and other defence and military, space flight, aviation, navigation, the integrated circuit of major projects such as emphasis such as communication national defence sophisticated weapons equipment, microelectronic component, still the special test device that does not have high low temperature aging reliability test and test, the external import of a large amount of dependences of employed test jack, price is very expensive, country will spend a large sum of foreign exchange imported product every year, order cycle time is longer, the product of special requirement can't be ordered goods, and the part staple product also influences China's military electronic devices and components research and development manufacturing schedule because of embargo.
Summary of the invention
For overcoming existing aging test socket in the deficiency aspect contact resistance, high temperature resistant and consistency and useful life, the utility model provides a kind of novel 64 string pitch that carry out high low temperature aging, test, screening and reliability test under integrated circuit, the online "on" position of microelectronic component that are exclusively used in only to be the pottery four limits lead-in wire flat packaging components and parts socket of 0.5mm.This socket can not only extend to-55 ℃～+ 150 ℃ from-25 ℃～+ 85 ℃ with the operating temperature range that wears out, once aging stream time reaches more than the 1500h (150 ℃), connect-disconnect life is more than 8000 times, and tested device is being carried out in high-temperature circulation test and the performance test process, have that the lead-in wire radical is many, the contact pitch is thin, contact resistance is little, high conformity, low connect-disconnect force, surface abrasion resistance and advantage easy to use, the reliability and the useful life of having improved socket greatly.
The technical scheme that the utility model technical solution problem is adopted is: structural design and dimensional requirement according to 64 lines, 0.5 pitch pottery, four limits lead-in wire flat packaging components and parts become three big part, i.e. socket, contact and positioners with jack design.Socket mainly is made up of seat, lid and hook, select the high temperature resistant type engineering plastics for use, manufacture jack body through the high-temperature injection molding technology thereof, contact is vertically rearranged by 64 lines of axial symmetry, the gold-plated reed of 0.5mm pitch, corresponding with tested device lead-out wire, be installed on respectively in 4 grooves of seat.The locking device of socket is made up of seat, lid, hook, briquetting and location-plate, the seat of socket, lid, hook and briquetting and location-plate can play the hold down gag effect, when tested device is placed on the location-plate, when the stressed downward upset of hook is meshed with seat, make lid and be installed in the briquetting that covers to produce displacement, because briquetting moves downward, tested device compresses contact, and stage clip is arranged on four pin of location-plate, and good elasticity is arranged, impel socket to reach and better compress effect.This utility model is with belonging to the pitch structure in a series of, the pitch of contact only has 0.5mm.Adopt and the corresponding mode of tested device lead-out wire, and form by center symmetry, four sides spread pattern.This utility model also adopts the novel type of being made of positioner location-plate and briquetting, and the lead-in wire of tested device is corresponding with contact and be installed on the location-plate.Carry out high-temperature circulation test and performance test after the energising.This flip-shell structure is designed to the structure of ZIF formula, wearing and tearing electrodeposited coating in the time of can avoiding the contact plug, influence electrical contact performance, a little less than thoroughly having solved big, the anti-environment of contact resistance in high-temperature circulation test and performance test process, the consistency difference and mechanical endurance long technological difficulties, can also satisfy the requirements of the different lead-in wires of tested device.
The beneficial effects of the utility model are: this utility model can satisfy general 64 lines of the army and the people lead-in wire flat packaging components and parts high-temperature circulation test of similar ceramic four limits with other and performance test; Of the present utility model succeeding in developing filled up domestic blank, substitutes import, for country has saved foreign exchange, for the user has saved cost, can obtain bigger economic benefit and social benefit.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments.
Fig. 1 is a contour structures of the present utility model vertical section structural map.
Fig. 2 is the utility model appearance structure vertical view.
Fig. 1: 11 12 stage clip 13 hooks of 78 torsion springs of 23 forward foot in a step contacts of pin contact (reed) (reed), 4 location-plate 5 stage clips, 6 rear foot contacts (reed), 9 lid 10 briquettings in 1
Embodiment
In Fig. 1, the first step: with contact be in the forward foot in a step reed (3) pin reed (1) and rear foot reed (6) by inserting in (2) with the corresponding structure of tested device lead-out wire; Second step: hook (13), stage clip (12), axle (7) are packed in the lid (9); The 3rd step: stage clip (5) and location-plate (4) are packed in (2); The 4th step: briquetting (10), axle (11) are packed in the lid (9); The 5th step: the lid that will install (9), axle (7) and torsion spring (8) are packed in (2) again.
