印制电路板网印中常见故障的排除方法

Print to Make the Exclusion Method that the Circuit Board Net Prints the Medium Familiar Breakdown

印制电路板(PCB)是电子及其它一些高新技术领域中最主要的电子部件,应用非常广泛,只要有集成电路和电子元器件存在的地方,几乎都离不开PCB。丝网印刷是大批量印刷印制电路板最常用的方法之一。近年来,随着丝网印刷技术和设备的不断提高,使丝网印刷与电子工业的联系更为密切,从而形成了电子丝网印刷的新领域。随着用于PCB行业的新型网印材料、网印工艺及检测设备日臻完善,使得当前的网印工艺技术也必须不断提高以适应高密度的PCB生产。由于印制线路板和其他丝网印刷在技术和材料等方面存在很多差异,因此要充分了解丝网印刷和印制线路板的特性、掌握印刷技巧、注意故障的分析处理,才能保证印制线路板的质量。

Print to make the electronics parts that the circuit board（PCB） is a most in electronics and a little bit other high new technique realmses, apply very extensively, as long as have a place, almost can not get away from the PCB.The silk screen printing is the large quantity printing to make one of the most in common use methods of circuit board.In recent years, raise continuously along with the silk screen printing technique and equipments, make the contact of the silk screen printing and the electronics industry more close, new realm of the electronics silk screen printing that thus become.Along with have used for the new net of the profession of PCB to print the material, net to print the craft and the examination equipmentses for day to attain perfect, make the current net print the production of PCB that the craft technique can adapt the high definition.Because printing to make the circuit plank and other silk screen printingses to exist a lot of differences in the technique and material etc., so want to understand the silk screen printing and print to make the circuit knothole characteristic well, controling to print the technique, the analytical processing that attention break down, then can guarantee to print to make the circuit knothole quantity.
