If air-breathing through hole, and in its interior grafting air intake duct, all air intake ducts are interconnected and come together in a total port, total port with
Outside vacuumize or be evacuated pumping unit connection, can be the negative pressure (or vacuum) continuously applied, can also with test when synchronously apply
Plus negative pressure or vacuum, and its negative pressure/vacuum is adjustable.While module testing, cooperation reaches optimal removal dust work(
Energy.So as to improve the reliability of test, the qualification rate of product is synchronously improved.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the module testing head assembly with dedusting function of the present utility model；
Fig. 2 is that a kind of air intake duct of the module testing head assembly with dedusting function of the present utility model is arranged on measuring head
Two row's testing needles between test pick-up performance figure；
A kind of Fig. 3 air intake ducts of the module testing head assembly with dedusting function of the present utility model are arranged on any two
Test pick-up performance figure between smart card test station.
Embodiment
In order to be able to preferably understand the technical solution of the utility model, below by specifically embodiment and combine
Accompanying drawing is described in detail：
Smart card module, have passed through after chip welding, gold ball bonding and final package, last procedure on a production line
It is exactly that function and parameter testing are carried out to packaged module, to the module of test failure, one jiao in module is stamped bad hole
It is used as mark.Because the tape base of flex tape is typically what is be made of glass fabric.This tape base is usually FR4, G10's
Glass fibre epoxy cloth is constituted, before being tested, before testing, it is necessary to connect to the technique being mutually conducted originally on electrical equipment
Line is punched out, to make original all contacts being electrically mutually conducted individually separated.While electrical isolation hole is punched,
Inevitably bring the dust of epoxy glass fabric；And glass bar band can also produce dust in continuously transmitting procedure.
At present to avoid the mistake survey that the loose contact produced during due to dust influence electrical performance testing is caused, generally exist
Before testing workstation, there is provided blowing or dust exhaust apparatus.But it is due to that smart card anury band is continuous in orbit
Transmission operation, also has quite a few dust existing close to test position and accumulate.These dust can not only produce test machine
It is raw to survey by mistake, originally qualified module is judged to unqualified.Moreover, these dust also result in the too fast fatigue of testing needle and failed.
These situations cannot be removed effectively, can aggravate module decrease in yield.
Referring to Fig. 1, a kind of module testing head assembly with dedusting function of the present utility model, including for placing intelligence
6 lower mould 1 and upper mould 2 for being tested smart card 6 can be blocked, the bottom of upper mould 2 is provided with measuring head 3, measuring head
Provided with double testing needle 31.Upper mould 2 offers air-breathing through hole, and one end of an air intake duct 4 is plugged in air-breathing through hole, the air-breathing
The other end of pipe 4 is L-shaped, and is connected with suction device 5.
Embodiment one：
Referring to Fig. 2, a kind of module testing head assembly with dedusting function of the present utility model, testing needle 31 is in intelligence
Engaged test point on card 6 is 32, and air-breathing through hole is opened between two row's testing needles of any one measuring head, and wherein grafting is inhaled
