510036 A7 B7 五、發明説明（1 ) 發明領域 本發明係關於一種點膠系統，特別是關於一種應用於捲 帶式封裝之點膠系統。 發明背景 捲帶式封裝是一種已廣泛應用在液晶顯示面板（LCD panel )的驅動元件之封裝方式，其係將複數個晶片設置於 整捲可撓性的膠帶上，其生產型態是整捲膠帶輸入，成品 也是以整捲膠帶的方式作為產出（reel-to-reel )。該捲帶式 封裝之主要結構包含：具有金凸塊的晶片、可撓性的捲 帶、内接合引腳（Inner Lead Bond ; ILB )與外接合引腳 (Outer Lead Bond ; 0LB )，且該内接合引腳與晶片上相對 應的金凸塊以熱壓合（thermo-compression)之方式銲接。一 般而言，為確保内接合引腳與晶片之結合不受外在環境之 影響與避免後續傳送過程中外力造成之損害，在晶片至内 接合引腳之空隙處需要點上絕緣膠且烘烤硬化，以給予產 品適當的保護。 目前習知之應用於捲帶式封裝的點膠系統1 0在量產前之 流程，如圖1之虛線所示，作業人員須先取一重量已知之 容器並驅動一點膠裝置1 2點入未確定重量的膠量，再送至 機台外部之離線微量天平1 5來進行重量檢測。由於目前使 用之點膠裝置1 2之膠量吐出控制器多採用時間與壓力為其 控制因子（簡單但不精確），而膠材本身於製程中又存在 諸多不確定的因素，往往在調整吐出膠量時不易掌握較穩 定的設定參數。因此需要一再重複點膠與離線測重的動 H:\hu\Lgc\日月光中說\ASEK259 (73355) .doc ~ 4 - 本紙張尺度適用中國國家標準(CNS) A4規格(210 X 297公釐） 裝 玎510036 A7 B7 V. Description of the Invention (1) Field of the Invention The present invention relates to a dispensing system, and more particularly to a dispensing system applied to a tape and reel packaging. BACKGROUND OF THE INVENTION Tape and reel packaging is a packaging method that has been widely used in driving elements of liquid crystal display panels (LCD panels). It consists of placing a plurality of wafers on a whole roll of flexible tape, and the production type is a whole roll. For tape input, the finished product is also reel-to-reel in the form of a whole roll of tape. The main structure of the tape and reel package includes: a wafer with gold bumps, a flexible tape, an inner bond bond (Inner Lead Bond; ILB) and an outer bond pin (Outer Lead Bond; 0LB), and the The internal bonding pins and the corresponding gold bumps on the wafer are soldered in a thermo-compression manner. Generally speaking, in order to ensure that the bonding of the internal bonding pins and the chip is not affected by the external environment and to avoid damage caused by external forces during subsequent transmission, the gap between the wafer and the internal bonding pins needs to be insulated and baked. Hardened to give the product proper protection. At present, the process of the conventional dispensing system 10 applied to tape and reel packaging is shown in the dashed line in Figure 1. The operator must first take a container of known weight and drive a little glue device. Determine the weight of the glue, and then send it to the offline microbalance 15 outside the machine for weight detection. Because the glue dispensing controller of the current dispensing device 12 uses time and pressure as its control factors (simple but inaccurate), and there are many uncertain factors in the glue itself in the manufacturing process, it is often adjusted for dispensing It is not easy to grasp the more stable setting parameters when the amount of glue. Therefore, it is necessary to repeat the dispensing and off-line weighing movements: H: \ hu \ Lgc \ Sun Moonlight said \ ASEK259 (73355) .doc ~ 4-This paper size applies the Chinese National Standard (CNS) A4 (210 X 297 mm) Decoration

Description of the invention (2) The process of mass production cannot be carried out until the continuous discharge volume meets the production standards, as shown by the solid line in Figure 1. During mass production, the dispensing volume of the dispensing device 12 may be caused by poor stability, which may gradually cause excessive or insufficient dispensing volume. If the glue layer is too thick, the final product cannot be placed in a limited assembly space; if the glue amount is too small, the risk of the inner bonding pins being exposed is not only bad, but also vulnerable to the external environment (such as moisture, temperature, etc.). Affects the product. In addition, there are also the following uncertain factors that may cause changes in the amount of dispensed: 1. The plastic material has a partial chemical reaction with the time it is placed at room temperature, so the viscosity gradually increases. 2. The amount of glue remaining in the hose of the dispensing device 12, that is, the weight of the material itself will affect the final discharge pressure. 3. The dispensing needle of the dispensing device 12 is continuously dispensed, so that some of the residual glue will harden and block the outlet pipe diameter. Looking at the above reasons, we can know that the conventional technology has the following disadvantages: 1. The setting work of the engineer before mass production requires the trial and error method to be used due to the uncertainty of the dispensing amount. Find better parameters. The conventional technology must adopt the offline detection method, which requires repeated sampling and weight detection. Therefore, the work of confirming the amount of dispensing each time is not only time-consuming and greatly reduces the utilization rate of the machine. 2. It is necessary to measure the glue thickness of the finished product in the material area with a certain sampling frequency, so it is impossible to monitor the product quality in continuous production in real time. When abnormalities are found, too many unqualified products have been produced.

Explanation of the invention (3 A7 B7 between the first glue dispensing system of the present invention. The purpose is to provide automatic confirmation of spit before mass production operations to save time spent in each offline inspection cycle :: < The second objective is to provide a dispensing system that can be automatically executed during mass production to avoid continuous production of undetected defective products, which is a waste of production costs. The second objective of the month is to provide an on-line weight measuring device In order to achieve the above-mentioned objective, the present invention provides a self-weighing dispensing system that is first used in the production of tape and reel packaging. The system There is a feeding device, which transfers the tape that has been combined with the grains to the dispensing device in a sequential and positioning manner. The action is to apply a liquid insulating glue to the gap between the inner bonding pins and the grains. Ensure that the bonding part is not affected by the external environment. Appropriate rubber fields should cover the area evenly to avoid the subsequent transmission of the bebes caused by external forces. The dispensing device controls the spitting applied to the hose. The output pressure, its action time, the movement of the dispensing path, the dispensing height, etc. Because the amount of dispensing affects the quality of the finished product greatly, the present invention is particularly designed to be located where the stroke of the dispensing device of the dispensing device is within reach. A weight measuring device generally uses a micro balance as a weight measuring device. The dispensing device will automatically move to the place where the micro 1 balance is located and place some glue on it, and the micro balance will automatically read the weight of the plastic material. And send the measured value to a programmable controller. It will perform the comparison between the measured value and the standard value.
