Compared with the prior art, the method and the device have the advantages of low cost and convenient use.
Description
Technical field
The present invention relates to product observation and measuring method and device, especially relate to the comprehensive observation of a kind of product based on polyphaser multi-angle and measuring method and device.
Background technology
In semiconductor packages industry, sticky brilliant object is that many separated crystal grain (Die) are placed on to lead frame (lead frame) or substrate (PCB) fixing with elargol (epoxy) adhesion.Lead frame or substrate provide the position (die pad Die pad) of an adhesion of crystal grain, and are preset with extended leg or the weld pad (pad) of extensible IC crystal grain circuit.And the object of bonding wire be the contact on crystal grain is connected on lead frame or substrate with superfine gold thread (18 ~ 50 μ m) within pin, thereby when the circuit signal of IC crystal grain is transferred to extraneous bonding wire, take crystal grain upper contact as the first solder joint, and the solder joint on interior pin is the second solder joint.First sinter the end points of gold thread into bead, then by little ball bond on the first solder joint (this is called the first weldering, first bond).Then according to the path lashing wire line designing, finally by gold thread pressure welding on the second solder joint.
The quality of the stickup of chip and the welding quality of bonding wire have conclusive impact to the stability of the electrical specification of semiconductor product and electron device, and therefore, there is strict control device in semiconductor packages enterprise to the quality of packaging technology.Wherein the test item for the stickup situation of chip and the welding quality of bonding wire reaches tens of more than.The optical check platform of specialty, by optical microscope, chip surface is amplified, to reach the many quality determinatives such as situation to chip surface quality, chip attach situation, bonding wire, carry out the inspection of real-time Multi-orientation multi-angle, thereby adjust in time the parameter of paster, welding gear operation, get rid of the problem that causes quality abnormal in production.
Yet, traditional optical checking equipment, only there is a top (Top View) to be installed over against optical microscope or the camera of chip, adopt this inspection method, can only carry out two dimension (plane) inspection to chip and bonding wire, cannot check the side of adhering chip (three-dimensional solid), as: the shape of elargol height, bonding wire and height, the size and shape etc. that is bonded to bead on the first solder joint and the second solder joint comprehensively check, also just cannot fully understand and get rid of the problem that causes quality abnormal in production.
Efficiently solve another limitation of traditional optical checking equipment, be mainly reflected in and can not be applicable to full-scale die size, mutually involving of the position of its enlargement ratio, illumination condition and capture, can not effectively use manually or the observation of the single side face of the one-sided prism of motorized motions.
?
Summary of the invention
The object of the invention is in order to solve the limitation of above-mentioned traditional optical checkout facility, a kind of comprehensive observation of the product based on polyphaser multi-angle and measuring method and device easy to use are provided.
Object of the present invention can be achieved through the following technical solutions:
The present invention includes: top camera (Top View) and forming around the oblique camera of the equally distributed inclination of top camera.Comprise: right camera (Right View), front camera (Front View), left camera (Left View), rear camera (Bear View), also comprise: supporting camera lens and light source, top camera adjustments frame, 4, XY slide unit, 4 of Z axis, 4 of camera fixed heads, 4 of camera fixed mounts.
Compared with prior art, the present invention has the following advantages:
5 independently camera can be simultaneously chip and bonding wire be carried out to end face, leading flank, trailing flank, left surface, right flank and carry out omnibearing inspection.Be applicable to full-scale die size, and be not subject to mutually the involving of position of enlargement ratio, illumination condition and capture.Effectively avoided the limitation of traditional one camera and single microscopical observation product.
5 independently camera there is the light source that can independently adjust, 5 cameras also can independently focus on, the independent camera position of adjusting, easy to use, are easy to obtain optimum image effect.Sightingpiston and the size of multi-angle camera have been opened, result according to the different azimuth of different product forms the difference that illumination is required, set respectively different observation conditions and camera setting, and illumination parameter, to reaching best product image and observing effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the omnibearing observation of a kind of product based on polyphaser multi-angle of the present invention and measuring method and device.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail:
As Fig. 1 shows, the comprehensive observation of a kind of product based on polyphaser and measuring method and device.This device comprises that top camera 1(is containing microscope and light source), right camera 2, front camera 3, left camera 4, rear camera 5, top camera adjustments frame 6, XY slide unit 7, Z axis 8, camera fixed head 9 and camera fixed mount 10, described XY slide unit 7, Z axis 8, camera fixed head 9 and camera fixed mount 10 are that 4 side cameras are established for coordinating.
The course of work of the present invention is as follows:
Adjustment when device is used first and changes product:
Put into product to top camera 1, adjust the operating distance of top microscope with camera, make camera 1 focusing correct images in top the most clear, adjust height and the brightness of top camera light source, make the image effect of top camera 1 optimum.
Adjust right camera 2, front camera 3, left camera 4, rear camera 5, to needed enlargement factor.
Adjust right camera 2, front camera 3, left camera 4, rear camera 5, affiliated XY slide unit 7, makes four cameras, aims at respectively the right, front, the left side, back of chip to deserved surrounding prism.
Adjust the affiliated Z axis 8 of four cameras, obtain correct focusing, make the image of right camera 2, front camera 3, left camera 4, rear camera 5, four cameras the most clear.And adjust the light source separately of four cameras, make each contented image effect best.
During normal use, only product need to be put into top camera under, can check product.
