The PCB manufacturing process involves several steps, including designing the board, drilling holes, applying copper, etching, and soldering components. The process starts with designing the board using computer-aided design (CAD) software. Once the design is finalized, the board is printed onto a ...

在图3-9所示的对话框中,共有5个选项页,我们主要在“Design”选项页中设置,在该页的“Size”栏目中,“UserUnits”项设置为“Mils”,“Accuracy”项(表示小数点后的位数)设置为“1”;在“Extents”栏目中,设置“LeftX”和“LowerY”均为-100(它们表示图纸上,左下角的坐标),在“Width”和“Height”中,都输入...
(注1)设计档在现今的制程能力下是无法达到的,比如说线与线、线与孔、孔与孔之间的间距太小,生产的时候容易造成短路,或是线宽太细容易造成断路无法生产,这时候板厂就会产生所谓的工程问卷EQ(Engineering Question)或DFM(Design For Manufacture)「工程沟通文章」送给客户做确认,因为有些地方可能是客户的特殊需求设计,...
into the PCB that facilitates connections between multiple PCB layers. An untented via, on the other hand, remains uncovered by a soldermask layer. The decision to expose or cover these vias carries both advantages and disadvantages contingent upon your specific design and manufacturing requirements....

进行拼版设计,必须创建一个新的brd数据。在新的brd数据中,必须添加Design_Outline、Outline、Route_Keepin、Package_Keepin等信息,添加标记、切割标记等机械信息来准备新的brd数据。由于PCB板制造商使用不同的尺寸,建议将拼版数据定义为Mechanical Symbol形式以供重复使用。
