Description
Technical field
The utility model is the interface agency about a kind of chip tester and thin film chip conveyer (Handler), by
So that spring needle seat tool is had the function of axially and also laterally moving by its internal several float layer, increases its spring needle stand and probe card
The precision of contraposition.
Background technique
Detection board of the general conventional dedicated before the encapsulation of printed circuit board (PCB), wafer or IC chip (IC)
It is usually detected with probe (Probe), this makes for reducing printed circuit board (PCB), wafer or IC chip (IC)
The cost for making process has quite positive influence.Defective products can be filtered out in advance using probe card detection, be further continued for later next
The processing procedure in stage can greatly reduce manufacturing cost, avoid the quality for wasting and influencing subsequent product.
In recent years because of the promotion of panel demand, either running gear, tablet computer, liquid crystal display, auto electronic
And there is use on life household electrical appliances.Display panel color is mainly the drive integrated circult chip (Driver on light-transmitting panel
IC), this is its core.
With the general grade of panel display, present mobile phone, computer screen and panel display are nearly all panels
Indicator screen, and traditional CRT screen, then because volume is excessively huge and high power consumption, slowly by panel display
Replace, the driving chip (Driver IC) on panel display periphery and the combination of circuit design become increasingly complex, panel display
Module must be exported various various forms of display signals using drive integrated circult chip (Driver IC) and find expression in face
On plate；Other elements in fit printed circuit board (PCB) are able to carry out the transmission of control signal.Panel display device at present
Rewinding type chip carrying encapsulation (Tape Carrier Package, TCP), coil type membrane of flip chip envelope can be divided into encapsulation technology
Fill the encapsulation technologies such as (Chip on Film, COF) and glass flip chip encapsulation (Chip on Glass, COG).
Rewinding type chip carrying encapsulation (Tape Carrier Package, TCP) and coil type thin membrane flip chip encapsulation (Chip
On Film, COF) processing procedure it is much like.Semiconductor chip is electrically connected at surface and is formed with wiring construction by coil type encapsulation

The electrical endpoint of chip is connect, outer end extends outwardly and formed with testing cushion, for electrical testing use.
Rewinding type chip carrying encapsulation (Tape Carrier Package, TCP) and coil type thin membrane flip chip encapsulation (Chip
On Film, COF) processing procedure difference be rewinding type chip carrying encapsulation (Tape Carrier Package, TCP) stitch
It is hanging, therefore in gluing, colloid must rely on jig temperature and the gravity of itself, it penetrates into below tape (TAPE),
It is allowed to that crystal can be surrounded up and down, also because crystal and foot are all hanging, rewinding type chip carrying encapsulation (Tape
Carrier Package, TCP) it is not appropriate for bending, otherwise have the danger of disconnected foot.And coil type thin membrane flip chip encapsulation (Chip
On Film, COF) foot be then directly to be flattened on tape (TAPE), chip directly and tape (TAPE) generate eutectic, painting
When glue, it is only necessary to apply the upper half, colloid will be seeped into beneath chips because of siphon principle, and coil type thin membrane flip chip encapsulation (Chip
On Film, COF) tape (TAPE) it is relatively thin, can bend, keep product more flexible on processing procedure.
When general tradition carries out thin film chip detection, chip detection interface agency is first installed in detection machine, then should
Chip detection seat is installed on thin film chip conveyer (Handler), and the spring needle stand and the film of chip detection seat
Probe card contraposition on chip conveyer, but if chip detection seat and the detection machine there has been a little mistake in installing
Difference, then the spring needle stand of chip detection seat, which is refilled, will occur error on the thin film chip conveyer, so that nothing
Method is accurately aligned with the probe card in the film conveyer, so that can miss followed by thin film chip detection
Difference causes the raising of manufacturing cost and increases its detection time.
