class="relatedlink">工艺</a>经验丰富CAD工程师依靠个人经验能作出较准确的判断。但是对于CAD新手，不可谓遇上一道难题。陶瓷线路板的载流能力取决与以下因素：线宽、线厚（铜箔厚度）、容许温升。大家都知道，陶瓷线基板走线越宽，载流能力越大。在此：假设在同等条件下，10MIL的走线能承受1A，那么50MIL的走线能承受多大电流，是5A吗？答案自然是否定的。请看以下来自国际权威机构提供的数据：线宽的单位是：Inch 1 oz.铜=35微米厚，2 oz=70微米厚, 1 OZ=0.035mm 1mil.=10-3inch. Trace Carrying Capacity per mil std 275</font><br /> <font size="3"><br /> </font><br /> <font size="3"> 实验：</font><br /> <font size="3"><br /> </font><br /> <font size="3"> 实验中还得考虑导线长度所产生的线电阻所引起的压降。陶瓷金属化加工工艺焊所上的锡只是为了增大电流容量，但很难控制锡的体积。1 OZ铜，1mm宽，一般作 1 - 3 A电流计，具体看你的线长、对压降要求。最大电流值应该是指在温升限制下的最大允许值，熔断值是温升到达铜的熔点的那个值。Eg. 50mil 1oz 温升1060度(即铜熔点)，电流是22.8A。</font><br /> <font size="3"><br /> </font><br /> <font size="3"> 在了解陶瓷线路板设计铜铂厚度、线宽和电流关系之前先让我们了解一下陶瓷线路板敷铜厚度的单位盎司、英寸和毫米之间的换算，在很多数据表中，陶瓷线路板的敷铜厚度常常用盎司做单位，它与英寸和毫米的转换关系如下：</font><br /> <font size="3"><br /> </font><br /> <font size="3"> 1 盎司 = 0.0014 英寸 = 0.0356 毫米（mm）</font><br /> <font size="3"><br /> </font><br /> <font size="3"> 2 盎司 = 0.0028 英寸 = 0.0712 毫米（mm）</font><br /> <br /> </td></tr></table> <div
