摘要
生产样品PCB板通常需要几天到1周的时间,这种较长时间的生产周期,不利于新产品研发时的快速验证。为了解决样品PCB板生产周期较长的问题,现有一种PCB板快速制造系统,可以实现在1天之内完成样品PCB板的制造。该系统的工艺步骤如下:钻孔及金属化孔→线路图形制作→阻焊图形制作→字符图形制作→助焊防氧化处理。该套系统能实现的加工能力为:最小孔径0.2mm,最小线宽2mil,线间最小间距0.8mil,加工精度±0.08mil。利用激光直写电路技术,该系统进一步解决了物理雕刻方式制作线路图形精度不够的问题,且在加工线路图形时对材料的热冲击效应较小,所以对加工精细间距的电路和射频微波电路有更好的效果,可有效解决高精度PCB样品板的快速制造问题。
It usually took several days to a week to produce sample PCB boards,and this longer manufacturing cycle was not beneficial for the verification of the research and development of new products.In order to solve the problem of longer manufacturing cycle of sample PCB boards,this Rapid manufacturing system of laser direct writing PCB was introduced,which can manufacture sample PCB boards within 1day.The process steps of the system were as follows:hole and hole metallization,line graphicsproduction,block welding graphics production,character graphics production,and anti-oxidation process by aid welding.This system can realize the processing capacity was the minimum-value aperture 0.2mm,the minimum-value line width 2mil,theminimum-value spacing between lines 0.8mil,the processing accuracy±0.08mil.By using the laser direct writing PCB technology,this system solveed the problem that the graphic precision of the line was not enough,and it had little effects on the thermal shock of the material when processing the circuit diagram.It had good effects on the precision spacing circuit and the radio frequency microwave circuit,and it can solve the problem of manufacturing sample PCB boards of high precision rapidly.
