Flex-Rigid PCB is mix FPC and Rigid PCB,followed special requirement and press them together. It’s compatible both of FPC and Rigid PCB advantages.Enginner always use 2 rigid PCBs,a flex pcb and a switch to connect them before Flex-Rigid PCB be published.Flex-Rigid PCB have strong resistance for bad application environment,it’s good
It’s important to know factors affecting of PTH throwing power to electronics products, then improve high aspect ratio for facilitating productivity.it’s good for electronics products reliability,reduce fabrication cost,improve productivity.
PTH
Plated through hole(PTH) is the crucial process of PCB manufacture. it need be plated enough copper in wall of hole for connect
Most of PCB manufacturers use Al sheet to plug vias.We use blank net to make solder mask and plug vias after many experiences, it's stability and reliability.
As the development of electronics industry, customers put high requirements for PCB surface mounted technology.Via plugging come into being as it connected all circuits,then
HDI PCB is High Density Interconnection PCB, It widely used in small BGA board as its more advantages:
Increased interconnection density by miniaturization of holes,pads and conductors.
Provides the possibility to have a via hole connect direct in the SMD or BGA pad.
Improved signal integrity due to reduced tracklength.
