Component Assembly - The service mount capability and trough hole that this design offers is a remarkable electrostatic and protective packaging.
Air Gap - The technology of flexible circuits rapidly increased the flexibility that is mainly achieved by layers with one main advantage “unbinding”. This is an essential aspect of the flexible circuit assembly, allowing the layer to freely flex.

Controlled Impedance - is responsible for increasing the signal switching speeds used transmission lines. Today’s designs is increasing the speed and minimizing the electrical reflections. It's help to ensure no errors between the transitions and the track interconnections. On the other hand, a perfectly designed and optimized controlled impedance can allow great control of the material of the cable and its physical dimensions. The controlled impedance in order to uniform in both thickness and electrical properties that is not a barrier for the industry.
Penalization - allows the circuit to be durable in components assembly. Once the panel is completed the circuit is ready for the end product.
Pressure Sensitive Adhesives (PSAs) - are used in projects and applications that a portion of the circuit has to be extra secured to a specific condition or location in the end product. The assembly process includes a releasing of the abradant liner and the adhesive with remains exposed is allowing the manufacturer to press the circuit in its place and keep it durable for use.
Shielding - when there is a demand to limit electrostatic and electromagnetic interferences that securing is applied. The shielding can be solid or electromagnetic. Both of the materials are insulating signal lines and any noise.
Manufacturing of Flexible Printed Circuit Board
___________________________________________
FPC is usually created by a photolithographic one sheet a time, also more efficient way is adopting R oll T o R oll ( RTR ).
1. Shearing: Crop the row material. 2. Computer Numerical Control (CNC): CNC is the drilling process. 3. Plating hole: Plate copper on hole. 4. Dry film lamination: create an etching layer of resistance. 5. Exposure: create an exposure area. 6. Development:The exposure area is polymerized and hardened by UV-rays. 7. Etching:remove the non-exposure area by chemical reaction. 8. Stripping:circuit pattern exposed. 9. Automated Optical Inspection (AOI):checks the quality of the printed board. 10. Coverlay pre-lamination:the board is covered with an insulation layer called “overlay”. 11. Hotpress:Bond between the overlay and the copper layer. 12. Metal finish: Coated to protect the terminal function. 13.Test: test the finished design.
