摘要

本研究利用濕蝕刻製程技術在環氧玻璃感光電路板上製作完成微銅保險絲；保險絲結構尺寸長為600μm，寬為80μm，銅層厚度為30μm。並利用ANSYS軟體對微保險絲進行數值模擬研究，以不同的輸入電流來預測溫度的變化；另藉由蝕刻時間的控制來獲得保險絲截面尺寸。實驗時，輸入電流以0.1安培為增加間隔，直到保險絲之熔斷電流止，並擷取溫度與電壓的變化以完成保險絲的熔斷特性。實驗結果顯示量測溫度和模擬的數據一致。且所製作完成之三種額定電流1.15安培、1.60安培及2.10安培的微保險絲，在額定電壓3.6伏特中皆測試通過國際標準安全規格。

This paper presents a micro copper fuse developed on a glass epoxy plate using wet etching technology. The fuse structure has a length of 600 μm and a width of 80μm. The thickness of the copper layer is 30μm. Numerical simulation was studied with ANSYS software to predict the temperature distribution of the micro fuse with variable input current. Different micro fuse cross sectional areas were obtained by controlling the etching time. The fuse characteristics were evaluated experimentally using input power to the blowing current at 0.1 A increment. Measured temperature showed good agreement with the simulation data. Under safety standard test requirement, the normal rated current of the design micro fuses are 1.15 A, 1.60 A and 2.10 A at an input voltage of 3.6 V.
