Abstract

The invention discloses a cleaning machine table for a semiconductor package products and a cleaning process thereof. The cleaning machine table comprises a control panel, a cleaning operation area and a drying area, wherein the control panel is arranged on the upper part of a front face of the machine table and is used for controlling the cleaning procedure; the cleaning operation area is arranged in the middle of the front face of the machine table, is in a shape of a hollow groove and comprises more than one cleaning slots, and the cleaning machine table is provided with an ultrasonic generation device corresponding to each cleaning slot so that the semiconductor package products in the cleaning slots can be cleaned by the ultrasonic waves; and the drying area is used for drying the cleaned products. The cleaning process comprises the following steps of ultrasonic chemical cleaning, ultrasonic washing in water and drying. After cleaned, the residual glue on the semiconductor package product can be nearly and completely removed so that the product performance is greatly improved and the following product function test is convenient.

Description

Technical field [0001] The invention relates to a semiconductor packaging technology, in particular to a cleaning machine and cleaning process for semiconductor packaging products. Background technique [0002] As we all know, the purpose of semiconductor packaging is to complete the electrical interconnection between the pins of the internal circuit of the bare chip and the signal output terminal of the external substrate, and at the same time protect the bare chip from damage by foreign objects, so that it can carry a certain external force and achieve good heat dissipation. With the increasing development of semiconductor technology and the market's demand for miniaturization, the lighter, thinner, shorter and smaller products have become the trend of technological development and the focus of industry competition. QFN (Quad Flat Non-leaded Package, QFN) quad flat non-leaded package is a more advanced packaging process in semiconductor packaging in recent years. The packaged p...
