Background technology
Plastic Package is the principal mode of Current electronic component package.Plastic-packaged electronic component light weight, it is small, at This is low, manufacturing process is simple, the use of this kind of packing forms so that Electronic Components Manufacturing efficiency is significantly improved.But it moulds It is that encapsulation is layered that the non-airtight of material encapsulation, which can bring potential integrity problem, most common failure mode, and encapsulation layering is logical Often cause burn into metallization fracture, the passivation layer of the fracture of plastic-packaged electronic component packaging body, chip and blaster fuse frame material broken The failures such as damage, soldered ball movement or wire breaking.Currently, usually using acoustic scan microscope inspection examining system detection plastic packaging electronics member Device encapsulation layering.
Plastic-packaged electronic component acoustic scan microscope detection usually detection medium (such as:Deionized water or alcohol) in It carries out, i.e., device is needed to be totally immersed into medium to be positioned in detection platform and is detected.For the smaller device of volume and quality, Since probe fast moves in detection process, device unbalance stress is caused, phenomena such as device floats, misplaces occurs, influences to examine Survey is normally carried out;Meanwhile when one-time detection number of devices is more, device need to impregnate the long period in medium.Due to plastic packaging The immersion of material, for there is the device of encapsulation layering, as the time that device impregnates in medium increases, acoustic scan is aobvious The delamination area that micro mirror detecting system can be detected out gradually decreases, or even cannot detect completely.Currently, suitable due to lacking Acoustic scan microscope inspection surveys positioning device, and usually all tested devices are positioned over simultaneously in detection medium, testing result Judgement depends on experience and the subjective understanding of testing staff, often there is certain deviation.Therefore, there is an urgent need to be detection Personnel provide it is a kind of suitable for a variety of plastic-packaged electronic components, can the multiple degrees of freedom strong operability, the adaptability that adjust it is high, repeatable The separate type acoustic scan detecting system positioning device utilized.
Invention content
The present invention exactly designs for insufficient existing for above-mentioned existing apparatus and provides a kind of acoustic scan microscope inspection Examining system separate type device positioning device, the purpose is to disclosure satisfy that and meanwhile to sizes, multiple plastic-packaged electronic components into Row acoustic scan detects.
The purpose of the present invention is achieved through the following technical solutions:
This kind of acoustic scan microscope inspection examining system separate type device positioning device, it is characterised in that:The positioning device packet The sample box 2 for including a pedestal 5 and being mounted in rows on pedestal 5, there are three be used for horizontal adjustment for processing on each sample box 2 Vertical tapped through hole 10, the position of these three tapped through holes 10 constitutes an equilateral triangle in the horizontal direction, these three Tapped through hole 10 is corresponding with three blind holes of the processing on the upper surface of pedestal 5, and a top is installed in each blind hole Locating piece 4 with V-groove, front end are that semicircular screw 3 passes through the tapped through hole 10 on sample box 2 to be inserted into blind hole, spiral shell The semicircle spherical surface for following closely 3 front ends is installed in the V-groove of locating piece 4, and three screws 3 rotate in tapped through hole 10 and drive sample Product box 2 moves up and down to adjust the level on 2 surface of sample box, one piece of silica-gel antiskid pad 1 is arranged on the surface of sample box 2, in silicon Plastic-packaged electronic component to be checked is placed in glue non-slip mat 1;
There are one the corresponding groove in upper and lower position, the interior settings of the groove for processing at the center of sample box 2 and pedestal 5 There are one magnet piece, the bottom of each magnet piece is fixed by a fastening bolt, and upper and lower two magnet pieces actuation makes sample box 2 can be fixed on pedestal 5.
The beneficial effects of the invention are as follows:
First, testing staff can be met by using acoustic scan microscope inspection examining system separate type device positioning device Various sizes and mass body product plastic-packaged electronic component detection, particularly with the plastic-packaged electronic component of small quality volume.Silica gel Non-slip mat 1 can fit closely fixation with various sizes plastic-packaged electronic component, when plastic-packaged electronic component being prevented to be placed in medium Movement floats.Silica-gel antiskid pad 1 can be picked and placeed freely, and reusable.
Second, for the first time in use, 2 surface of sample box is by semicircular screw 3 and the locating piece with V-groove 4 adjusts water It is flat, subsequently no longer need leveling.High-volume plastic-packaged electronic component is detected, when use will first can be used to that detection parameters to be arranged Sample box 2 be placed in medium, after being provided with again by remaining placement plastic-packaged electronic component sample box 2 be placed in medium, shorten Plastic-packaged electronic component soaking time in medium can effectively solve the problems, such as that tested plastic-packaged electronic component medium immerses.
The material of third, separate type acoustic scan detecting system positioning device silica-gel antiskid pad 1 is silica gel, 2 He of sample box Pedestal 5 uses organic glass, semicircular screw 3 and locating piece 4 that stainless steel, fastening bolt and magnet piece is used to use neodymium magnetic Body, these materials are reusable, will not react with medium.
Description of the drawings
Fig. 1 is the dimensional structure diagram of apparatus of the present invention
Fig. 2 is the sectional view of apparatus of the present invention
Specific implementation mode
Apparatus of the present invention are further described below with reference to drawings and examples:
Shown in attached drawing 1~2, this kind of acoustic scan microscope inspection examining system separate type device positioning device, feature It is:The sample box 2 that the positioning device includes a pedestal 5 and is mounted in rows on pedestal 5, is processed on each sample box 2 There are three the vertical tapped through holes 10 for being used for horizontal adjustment, and the position of these three tapped through holes 10 constitutes one in the horizontal direction Equilateral triangle, these three tapped through holes 10 are corresponding with three blind holes of the processing on the upper surface of pedestal 5, blind at each The locating piece 4 of one top tape V-groove is installed, front end is tapped through hole 10 of the semicircular screw 3 on sample box 2 in hole It is inserted into blind hole, the semicircle spherical surface of 3 front end of screw is installed in the V-groove of locating piece 4, and three screws 3 are in tapped through hole It is rotated in 10 and drives sample box 2 to move up and down to adjust the level on 2 surface of sample box, be arranged one piece on the surface of sample box 2 Silica-gel antiskid pad 1 places plastic-packaged electronic component to be checked on silica-gel antiskid pad 1;
