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

Flex-Rigid PCB Pros and Cons:
• Reliability: Excellent due to reduced need for solder joints;
• Cost: Lower cost compared to flexible boards;
• Temperature Resistance: Excellent;
• Ideal for moderate to slightly higher than normal movement and stress;
• More flexible and pliable than conventional boards;
• Long-term reliability thanks to fewer interconnects and components;
• Requires minimal maintenance;
