Description

1248910 ____^_:_. V. Description of the Invention (1) Technical Field of the Invention The present invention relates to a tray transporting apparatus, and more particularly to an improvement of a semiconductor component that can be stably moved during the process of carrying a pallet. The rear tray transporting device holds a fixed tray by a first fixing device, and a correcting device corrects the left and right tilt of the clamped fixed tray, and covers the clamped fixed tray on the carrying tray Above. 'Λ 【Prior Art】 In general, 'semiconductor components must be tested on the production line before they are shipped. Test a variety of logic components with a horizontal handling device, such as: small flat packages (QFp), ball grid array packages (BGA), pin grid arrays (pin grid arrays) ; pGA) and small outline packages (s〇p), these are the non-memory (n〇niem〇ry) semiconductor package technology seen in semiconductor components and the tray of the horizontal carrying device conductor components, and will be flat On the set bracket, Ϊ: The result of the test removes each semiconductor component from the tray. Automatically moving a semiconductor component placed in one of the test stations to perform a semiconductor component test in the process, and classifying the components according to the components, and finally, and semiconductor

In recent years, there has been an increasing demand for body components to be semi-conducting, for example, in a warmer or more turbulent environment, and to make it work stably. The flat handling device Jiang main = rut low temperature working environment . Therefore, it is also necessary to measure the temperature of the water and the cattle conductor at the temperature set by the user.

Page 9 Test and ί ί ί: ί or the lower temperature environment for the semiconductor components and the φ body of the plate also need to stably pass. Loading trays: When the conductor elements are carried by the horizontal carrying device or from the bearing/testing, these semiconductor components are often scattered on the & water warfare trays. of.疋Because the volume of the semiconductor is too small and the weight is too light, the tray opens the patent No. 1(), 8 1 8 54, revealing a conventional diagram, the two f f1 diagrams are not The tray transfer device is used for transporting the tray in the transport device. As shown in FIG. 1 , a substrate 1 can be disposed on the substrate 10 along the crucible by rotation. Ball type screw correction: and ί two move 7. And a first support plate 2° and a second support plate 3.
