f第三章硬件制作以及程序的下载调试
31电路板制作
首先用protel99SE绘制原理图生成PCB并手工调整布局之后手工布线。布线时要设置电气规则设置安全距离对电源线、地线加粗同时要尽量加大焊盘尽可能地避免跳线PCB图如下所示。
PCB完成后打印在热转印纸上覆铜板先用砂纸打磨去除上面防氧化胶水将热转印纸紧贴在板子上并用熨斗熨几分钟之后在自来水冲洗下揭去热转印纸待板子风干观察上面的油墨线路是否有缺损若有可用油墨笔将缺损处瞄一下即可。待油墨风干后放在三氯化铁腐蚀液里腐蚀十分钟左右腐蚀时要不断晃动腐蚀液加快腐蚀速度直到板上面未覆油墨的铜全部腐蚀完取出板子放在自来水中冲洗干净风干后就可以钻孔了待孔钻完将板子放在自来水中用砂纸打磨去覆铜上的油墨到此板子就制r
