What is 2-Layer Flexible PCB?
In essence, the 2-Layer Flexible PCB deploys a flexible laminate for its base material. It is composed of two (2) conductive layers that are integrated into a polyimide base.
It has become popular because of its enhanced impedance control and reliability. They are versatile boards that can be applied in complex circuitry.
They are widely deployed in repeaters, digital cameras, cell phones, LED displays, and wireless floating heads. Also, it comes with various thickness selections from 0.15 mm up to 3.0 mm and has a maximum panel size of 18” by 24” board.
Its stack-up has a central base film referred to as a substrate, then two copper foils, up to four adhesive layers, and two protective coatings. Call us right away to obtain our decently priced, high-quality PCB items!
Manufacturing Layout of a 2-Layer Flexible PCB
As its name implies, 2-Layer Flexible PCB is composed of two conductive layers that may or may not have plated-through holes in its production. Nevertheless, it is the industry’s most widely preferred type of variation for this particular board.
It has been dominating the production process of this board because of its connections for electronic components since they are accessible on either side of the board.
Thus, placing components on both sides of the board is possible. Moreover, since the layout of this board necessitates protective layers, they can be applied on both sides.
