预涂布感光敷铜板不但可以用来制作单面印刷电路板,而且用其制作双面印刷电路板也十分方便快捷,这对于科研新品开发、教学用单块及小批量业余电子制作都是非常便利的。下面介绍用“即时得”预涂布感光敷铜板制作双面印刷电路板的具体操作方法。 一、画双面印刷电路板图:用手工或电脑Potel绘制印刷电路板图的方法在许多报刊、书籍上已有详细刊载,这里只强调两点: 1.画电路板图时过孔要少,尽量用元件的引脚作电路板的过孔。
Pre-coated photosensitive copper clad laminate can not only be used to make single-sided printed circuit board, but also its production of double-sided printed circuit board is also very convenient and rapid, which for the development of new products, teaching a single and small batches of amateur electronic production is very convenient. The following describes the use of “instant” pre-coated copper-clad printed circuit board production of double-sided printed circuit board specific methods of operation. First, draw the double-sided printed circuit board diagram: Manual or computer Potel drawing printed circuit board method in many newspapers, books have been published in detail, only to emphasize two points: 1. Draw circuit board when the hole to be less , Try to use the component pins for the circuit board through hole.
