Description
本发明涉及一种计算机方法和系统,特别是涉及一种设计冷板的方法和设计系统。
针对双列直插式封装(DIP,dual inline-pin package)插件元件设计的冷板,工艺要求是先安装冷板。此处所述的冷板是一块整体厚度一致的金属板,紧贴印刷电路板(PCB,Printed Circuit Board)固定,再安装插件元件。对需要散热的DIP插件本体下面紧贴冷板安装,类似骑在冷板条上安装;对于无需散热的插件元件,例如插件电容,连接器等等,冷板对元件的安装位置会挖空,让其可以正常安装。
先有技术中,生成DIP插件元件的冷板时,需要由设计人员根据需要对散热的元件位置手工进行绘制区域,例如:哪些元件区域挖空,哪些地方是金属板,哪些插件孔区域要挖空。然而这种方式却存在如下几个问题:一个是绘制效率较低,当元件数量较多或者结构复杂的时候,需要花费较大的人力和时间在该过程中;另一个是其需要人工基于加工要求对绘制区域进行检查,容易产生检查不准确等问题;再一个是不方便修改,当PCB板的设计图纸发生变动或更改时,需要重新人工绘制相应的冷板图纸。
