制作印刷电路板,是一个电子爱好者经常遇到的事使用印刷电路板可以省去布线工序,提高焊接质量,特别是较为复杂的电路更需要使用它。所以,制作印刷电路板已经成为维修和电子制作必不可少的重要环节。怎样才能快速、高效、高质量地制作印刷电路板呢?过去沿用的是“三氯化铁溶液”腐蚀法,这种方法腐蚀慢、效率低不适宜快速及时制作和修理。经过实验,用“盐酸过氧(?)氢溶液”腐蚀制作电路板,效果较理想。室温7C腐蚀9CM×5.5CM的一块电路板,平均只需8分钟,而过去的方法(三氯化铁法),则需49分钟,提高工效六倍,且用两种方法做出的板不分彼此。
Printed circuit board is often encountered by an electronic enthusiast Printed circuit board can eliminate the wiring process, improve the quality of welding, especially the more complex circuits need to use it. Therefore, the production of printed circuit board has become an essential part of maintenance and electronic production. How to make printed circuit board quickly, efficiently and high quality? In the past is the “ferric chloride solution” corrosion method, this method slow corrosion, low efficiency is not suitable for rapid and timely production and repair. After experiments, with “hydrogen peroxide (?) Hydrogen solution” corrosion circuit board, the effect is better. Room temperature 7C corrosion 9CM × 5.5CM of a circuit board, an average of only 8 minutes, while the previous method (ferric chloride method), you need 49 minutes to improve work efficiency sixfold, and the two methods to make the board is not Divided each other.
