Flex boards with stiffener are formed by a flexible part of polyamide material to which a rigid material of FR4 is attached.
printed circuit with controlled impedance, the impedance will be controlled by acting on the dimensions of the tracks and the distance between them, i.e. the insulation. For a multilayer printed board with Flexible stiffener circuit with a specific stack-up, it must be taken into account that the internal tracks with controlled impedance are shielded
and the printed circuit through its continuous improvement was one of the first aids that allowed this modernization. The smaller and smaller dimensions and the flexibility of the Flexible stiffener board with printed circuit board made in recent years have greatly helped fields such as medicine and aeronautics to benefit
surface of the printed circuit less on the soldering pads and it also has a role of antioxidation of the copper traces. Being a substance with a high degree of with stiffener board Flexible electrical insulation, the soldering mask offers the printed circuit the possibility of having a high density of
