物理实验经常做印刷电路板 ,用透明不干胶带代替漆层绘制印刷电路板 ,方法简单 ,材料易找 ,成本低而且效果好 .现将方法介绍如下 .先用砂纸把敷铜板打磨干净 ,用复写纸把草图复印在敷铜板上 .用市场上易买到的包装用宽透明不干胶带把敷铜板全贴满 ,并用手掌压平整 .找一把小刻? Physical experiments often do printed circuit board, with transparent adhesive tape instead of paint to draw the printed circuit board, the method is simple, easy to find the material, low cost and good effect. Now the method is as follows. Copies of sketches photocopied on the copper clad laminate.Use commercially available packaging with a wide transparent adhesive tape to the full adhesion of the copper clad laminate, and the pressure with the palm of your hand.
