style="line-height:200%;">原標題:<strong>主流精密電阻技術優點以及缺點都有哪些？（干貨分享）</strong></span></span></span><br /> <img alt="精密電阻" src="/u_file/photo/20200504/03cc3571fb.jpg" /><br /> <span style="font-family:微軟雅黑,arial;"><span style="font-size:16px;"><span style="line-height:200%;"><strong>一、精密厚膜電阻</strong><br /> 通過對厚膜電阻漿料的持續改進，最精密的厚膜電阻技術已經可以做到±5ppm/°C的溫漂，甚至通過使用多個可以互相補償的厚膜電阻芯片最終達到±2ppm/°C的溫漂。<br /> <strong>精密厚膜電阻優點</strong>：其最高精度也可以達到±0.01%。在高壓高阻值高精密的應用中精密厚膜電阻是主流的技術。<br /> <strong>精密厚膜電阻缺點</strong>：厚膜電阻的缺點是在低阻值的部分很難做到高精密低溫漂，噪聲指標也不好，長期穩定性一般都是比其他精密電阻差。<br /> 二、<strong>精密薄膜電阻</strong><br /> 精密薄膜電阻的技術發展代表了可以被大量商用的精密電阻技術，也是目前最流行的精密電阻技術。<br /> <strong>精密薄膜電阻優點</strong>：通過長時間多層的膜層沉積，高精密的調阻和后期的篩選，最優的精密薄膜電阻可以達到±2ppm/°C的溫漂和±0.01%的精度，以及很好的長期穩定性。<br /> <strong>精密薄膜電阻缺點</strong>：其缺點是功率做不大，低阻值部分指標不好，不抗靜電，功率系數差，很難滿足小批量的供貨，且不同批次的一致性不好。<br /> 三、<strong>精密金屬膜電阻</strong><br /> <strong>精密金屬膜電阻優點</strong>：精密金屬膜電阻的各項指標和精密薄膜電阻類似，晶圓精密金屬膜電阻有被貼片精密薄膜電阻替代的趨勢，但插腳的精密金屬膜電阻仍然是主流的低成本的精密電阻技術。<br /> <strong>精密金屬膜電阻缺點</strong>：和精密薄膜電阻一樣，由于調阻會造成熱點效應，影響電阻的穩定性和可靠性。<br /> 四、<strong>精密線繞電阻</strong><br /> 作為最早的<a href="http://www.cppestcontrol.com/products-list/i-17/">精密電阻</a>技術，高精密的線繞電阻溫漂可以做到±1ppm/°C, 且精度可以做到±0.001%，這是薄膜和厚膜電阻沒有辦法做到的。<br /> <strong>精密線繞電阻優點</strong>：最好的精密線繞電阻其阻值可以做到接近50M，適合超精密高阻值的應用。<br /> <strong>精密線繞電阻缺點</strong>：由于其他電阻技術的發展，精密線繞電阻趨于被淘汰的邊緣，因為其價格昂貴，有電感等缺點。<br /> 五、<strong>精密箔電阻</strong><br /> 雖然精密箔電阻早在1962年發明，截至目前他仍然是最精密的電阻技術，通過把鎳鉻合金黏貼在陶瓷基板上進行應力平衡，得到接近于零的溫漂，通過激光刻蝕電阻圖形以及調阻，可以得到高達±0.001%的精度。<br /> <strong>精密箔電阻優點</strong>：最好的箔電阻存儲6年阻值僅漂移±2ppm，抗靜電，無感無容，無熱點設計，低噪聲，低電壓系數。<br /> <strong>精密箔電阻缺點</strong>：箔電阻的缺點是阻值做不了很高，最大尺寸的貼片電阻最高只能做到150K，最大尺寸的插腳電阻阻值最高只能做到2M。<br /> 深圳市<a
