冷板的审查方法、系统、计算机可读存储介质及设备 技术领域
本发明属于电路板检测技术领域,涉及一种审查方法和系统,特别是涉及一种冷板的审查方法、系统、计算机可读存储介质及设备。
背景技术
电子行业的设计人员在设计PCB线路板时为了元件散热通常会设计一个冷板,其主要用于元件散热,以及支撑PCBA和增加强度的目的。目前行业内有面向DIP插件元件设计的冷板,和面向SMD表贴元件设计的冷板。
针对DIP插件元件设计的冷板,工艺要求是先安装冷板,再安装插件元件。而该冷板是一块整体厚度一致的金属板,其需要紧贴PCB板固定;对需要散热的DIP插件本体下面紧贴冷板安装,相当于DIP类的插件元件是骑在冷板条上安装的。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,相当于同没有冷板的安装是一样的。
现有方法针对以上DIP插件元件的冷板生成有两种:
1、由设计人员根据需要进行散热的元件位置手工进行区域绘制: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;
2、通过软件自动生成冷板图形。
对于以上两种方法产生的冷板图形都可能会带来实际生产中的问题,比如PCB板上有元器件和各种焊盘等,这些都有可能会在实际组装后造成碰撞、干涉、维修等方面的问题。而目前这些问题行业内是通过工程师人工对比冷板图与PCB板来检查可能造成问题的地方,或者在实际组装时才能发现。这样的审查方法不但效率低下、准确率低,而且还有很多问题通过上述方法无法被发现。
因此,如何提供一种冷板的审查方法、系统、计算机可读存储介质及设备,以解决现有技术通过工程师人工对比冷板图与PCB板进行检查,造成的效率低下,准确率低等种种缺陷,实已成为本领域技术人员亟待解决的技术问题。
