Description

A kind of acoustic scan microscope inspection examining system separate type device positioner

Technical field

This utility model is a kind of acoustic scan microscope inspection examining system separate type device positioner, Belong to the technical field of structures of product.

Background technology

Plastic Package is the principal mode of Current electronic component package.Plastic-packaged electronic component quality Gently, volume is little, low cost, manufacturing process simple, the employing of this kind of packing forms so that electronics Components and parts production efficiency is significantly improved.But the non-airtight of Plastic Package can bring potential can By sex chromosome mosaicism, modal failure mode is encapsulation layering, and encapsulation layering generally causes plastic packaging electronics The burn into metallization fracture of the fracture of component package body, chip and blaster fuse frame material, passivation layer Damaged, soldered ball moves or wire breaking etc. lost efficacy.At present, acoustic scan microscope inspection is generally used Examining system detection plastic-packaged electronic component encapsulation layering.

Plastic-packaged electronic component acoustic scan microscopic examination generally detection medium (such as: go from Sub-water or ethanol) in carry out, i.e. device needs to be totally immersed into medium and is positioned in detection platform and carries out Detection.It is for the device that volume and quality are less, the most mobile due to probe during detection, Cause device unbalance stress, occur device float, the phenomenon such as dislocation, affect detection and be normally carried out； Meanwhile, when one-time detection number of devices is more, device need to soak the long period in medium.By In the immersion of capsulation material, for there is the device of encapsulation layering, along with device soaks in medium The time of bubble increases, and the delamination area that acoustic scan microscope inspection examining system can be detected by out gradually subtracts Few, even can not detect completely.At present, owing to lacking suitable acoustic scan microscope inspection mensuration All tested devices are generally positioned in detection medium, the judgement of testing result by position device simultaneously Depend on experience and the subjective understanding of testing staff, often there is certain deviation.Therefore, In the urgent need to for testing staff provide one be applicable to multiple plastic-packaged electronic component, can multiple degrees of freedom The strong operability of regulation, adaptability are high, the separate type acoustic scan detecting system of repeatable utilization is fixed Position device.

Utility model content

Deficiency that this utility model exists for above-mentioned existing apparatus just and design and provide a kind of sound Learning scanning microscope detecting system separate type device positioner, it is the most right to its objective is to disclosure satisfy that Sizes, multiple plastic-packaged electronic component carry out acoustic scan detection.

The purpose of this utility model is achieved through the following technical solutions:

This kind of acoustic scan microscope inspection examining system separate type device positioner, it is characterised in that: This positioner includes a base (5) and the sample box (2) being arranged in rows on base (5), often Three vertical tapped through holes (10) for horizontal adjustment, these three it is machined with on individual sample box (2) The position of tapped through hole (10) constitutes an equilateral triangle, these three tapped through hole in the horizontal direction (10) corresponding with the processing three blind holes on the upper surface of base (5), pacify in each blind hole Filling the locating piece (4) of a top tape V-groove, front end is that semicircular screw (3) is through sample box (2) tapped through hole (10) on is inserted in blind hole, and the semicircle sphere of screw (3) front end is installed in In the V-groove of locating piece (4), three screws (3) rotate in tapped through hole (10) and drive sample Box (2) moves up and down the level adjusting sample box (2) surface, in the surface configuration one of sample box (2) Block silica-gel antiskid pad (1), at the plastic-packaged electronic component that the upper placement of silica-gel antiskid pad (1) is to be checked；

Corresponding recessed in upper and lower position it is machined with the center of base (5) at sample box (2) Groove, is provided with a magnet piece (7) in this groove, the bottom of each magnet piece (7) is tight by one Fixing bolt (6) is fixed, and the adhesive of upper and lower two magnet pieces (7) makes sample box (2) can be fixed on base (5) on.

The beneficial effects of the utility model are:

First, testing staff positions by using acoustic scan microscope inspection examining system separate type device Device, can meet various sizes and mass body amasss plastic-packaged electronic component detection, particularly with little matter The plastic-packaged electronic component of amount volume.Silica-gel antiskid pad (1) can be with various sizes plastic-packaged electronic component Fit tightly fixing, prevent plastic-packaged electronic component from moving when being placed in medium or floating.Silica gel is prevented Skidding (1) can freely pick and place, and reusable.

Second, when using first, sample box (2) surface is by semicircular screw (3) and band V-type The locating piece (4) of groove adjusts level, follow-up is no longer necessary to leveling.For high-volume plastic packaging electronics unit device Part detects, and first the sample box (2) being used for arranging detection parameter can be placed in medium, set up during use Remaining sample box (2) placing plastic-packaged electronic component is placed in medium by Cheng Houzai, shortens plastic packaging electricity Sub-components and parts soak time in medium, can effectively solve tested plastic-packaged electronic component medium and immerse Problem.

3rd, the material of separate type acoustic scan detecting system positioner silica-gel antiskid pad (1) is silicon Glue, sample box (2) and base (5) use lucite, semicircular screw (3) and locating piece (4) Using rustless steel, fastening bolt (6) and magnet piece (7) to use neodymium magnet, these materials are repeatable to be made With, all will not react with medium.
