NURBS曲線插值器應用於選擇性雷射燒結電路

Abstract

本論文是以NURBS曲線插值器結合選擇性雷射燒結系統，並於奈米銀溶液塗佈的PET軟性基板上進行雷射燒結。研究中利用雷射減少基材的破壞，可在較低之雷射功率下有效燒結奈米銀粒子。為確保奈米銀經燒結後可做為後續導線使用，實驗中透過設計雷射功率100~250 mW(每50 mW遞增)與雷射掃描速2~5 mm/s(每1 mm/s遞增)，取其導電性最佳之數據做為後續NURBS範例之使用。為了彰顯NURBS曲線插值器是否能有效改善雷射掃描速度連續性，以蝴蝶狀的NURBS曲線插值分析XY雙軸運動平台軌跡。燒結後，將研究中的G06 NURBS曲線插值與G01線性插值在轉彎處比較線寬的變化結果。最後以平面螺旋式電感做為其應用展示。

In this thesis, we developed a selective laser sintering (SLS) system with NURBS curve interpolator, and sintering the silver nanoparticles ink on a flexible substrate. Take advantage of laser for reducing thermal damage of substrate, which allow us to use lower laser power to sinter the silver nanoparticles ink. To ensure that sintered silver nanoparticles can be used for conductive line, the experiment are designed for laser power in the range of 100 ~250 mW and the scanning speed in the range of 2~5 mm/s. The best electrical conductivity of the experiment result is used in the following experiment. In order to show if NURBS interpolator can effectively improve the continuity of laser scanning speed, by using a butterfly-shaped of NURBS curve as example to analyze the path of the motion stage. After sintering, traditional method (G01) with purposed method (G06) for the change rate of linewidth in the corner of the path are compared. At last, a planar spiral inductance for application is demonstrated.
