12Layer Rigid-flex HDI PCBA for Tcon LCM / Soft gold finger
Printed circuit boards (PCBs) connect electrical components
together using discrete wiring, resulting in a complete and
functional unit. PCBs can be as simple as one or two layers of
copper circuits, but are far more likely to have many layers of
circuitry. The layers are necessary for the designer to “route” all
of the circuits between the components – where one, two, or even
eight layers of circuitry may not be enough to complete their
design and make all of their connections.
While all circuit boards perform the same basic function as a
substrate for the electronic components, the design and materials
of their construction are the key distinguishing points. Circuit
boards are custom-tailored to their particular application.
Due to development trend of aerospace products including light
weight, miniaturization, multifunction and assembly densification,
higher requirement has been set up for Printed Circuit Board (PCB)
technology and manufacturing process. Flexible PCBs are a type of
circuit boards that are made of flexible substrate material and
feature more advantages than ordinarily rigid PCBs:
• Lower thickness
• Lighter weight
• Dynamically bendable
• Accessible for 3D interconnection assembly
• Higher freedom on electronic design and mechanical design
• More space-saving
