Some embodiments relate to micro vias in printed circuit boards (PCBs). In an example, a PCB may include a PCB substrate and a micro via. The micro via may extend between opposing surfaces of the PCB substrate and may have a diameter less than or equal to about 100 microns. In another...
高密度电路板，这个不清楚，顾名思义，可能是指现在高密度零件的PCB板吧，比如手机PCB。这几个制程一般的板都常见。很多PCB打样的厂家能做，百度下PCB打样就知道了。右边的导通结构，第一个导通孔就是PTH （PLATING Through Hole），上面讲到的插件零件的脚一般都是PTH，只要是2层以上PCB，一般必须有...

两种方案各有优缺点,但为将Micro LED显示屏快速推向市场,雷曼光电早在四年多前就与上游合作伙伴合作研发PM驱动结构+玻璃基板的创新方案,并联合突破了TGV(Through-Glass Via)玻璃通孔技术的难题。 另外,屠孟龙还提到了玻璃基Micro LED COB封装所面临的挑战。由于Micro LED芯片的尺寸非常小,传统的机械式转移技术已经...
