首先取出一块敷铜板,用细砂纸将铜箔表面打磨,再铺上一层复写纸,然后将需要制作的电路制版图正面紧贴在复写纸面上,并用铅笔(或圆珠笔)在原电路制版图上勾画,将其复印在敷铜板上。然后小心撕开复写纸,对照原图看有无不清楚或遗漏之处.核对无误后用锋利小刀(或废旧锯皮自制小马)在敷铜板上沿着电路边沿刻画(许意多使点劲),将画后多余的铜铂翘起一点皮,用指甲刀慢慢地将多余铜箔撕掉(铜箔很薄, First, remove a piece of copper clad laminate, polish the surface of the copper foil with fine sandpaper, and then apply a layer of carbon paper. Then, place the front of the circuit board to be made on the carbon paper and mark it with a pencil (or ballpoint pen) , Copy it on the copper clad laminate. And then carefully ripped the copy paper, the control of the original picture to see whether there is any unclear or omission.Check out the correct use of a sharp knife (or scrap leather pony homemade pony) along the copper edge of the circuit along the edge portraits , Will draw after the excess of copper platinum tilt a little skin, use a nail clipper to slowly tear the excess copper foil (thin copper foil,
