6 Layer Rigid-Flex PCB with 2 Layer Flex PCB with Unsupported Fingers

 

Often, the term fingers is used with the printed circuit board design. Fingers are nothing but the terminals located on the card-edge connectors. These fingers are most commonly plated with gold, and hence also referred to as gold fingers. The gold plating done on the fingers make them highly resistant to various types of acids. Thus, the printed circuit boards can perform for a longer period of time. In addition to this, the gold platting on these terminals help increase the overall strength and resistance of the PCBs in extremely harsh application environments. You can choose to go with supported or unsupported fingers while designing the printed circuit boards. Rigiflex is one of the leading, and well-known manufacturers of high-quality 6 layer rigid flexible printed circuit boards with 2 layer flex with unsupported fingers.

The model of this 6 layer rigid flex PCB is Rigid-flex Board-6L. As the name suggests, the circuit board has 6 layers, and is made from materials like polyimide, polyester (PET), and Kapton. We have the capability to manufacture these rigid-flex printed circuit boards in a variety of layer options varying from 1 layer to 20 layers. These PCBs can be manufactured using single sided (0.050 mm), double sided (0.075 mm), drilling plated through-hole (0.2 mm) methods. The conductor width of these PCBs is 0.025 mm, hole diameter is 0.05, accumulated pitch is 0.05 mm, and outline dimension is 0.05 mm. The insulation resistance of these circuit boards is 1000 MW, and the dielectric strength is 5 KV.
