Quick Turn Rigid Flex PCB Material
Quick turn rigid flex PCB processing substrate material and flexible circuit board, the same as flexible copper clad laminate FCCL. FCCL refers to the copper coated plate formed by bonding with copper foil on one or both sides of flexible insulating materials such as polyimide film and polyester film through a certain process. quick turn rigid flex PCB's FCCL material consists of insulating base film material, metal conductor foil, adhesive.
Quick Turn Rigid Flex PCB Design Attention Point
1. For the quick turn rigid flex PCB requiring repeated bending, single-layer flexible structure is used, and RA copper is used to increase fatigue life.
2. Quick turn rigid flex PCB recommended to keep flexible circuit copper wire bending along the vertical direction.
3. Quick turn rigid flex PCB design to avoid using obtrusive right Angle or rigid straight 45° Angle wiring, but use arc Angle wiring mode, which can reduce the stress of copper skin in the bending process.
4. Don't suddenly change the width of quick turn rigid flex PCB design wire, the sudden change of wire width or connection to the welding pad will cause weak points of strength.
5. Provide reinforcement for quick turn rigid flex PCB welding pad.
6. Quick turn rigid flex PCB design to maintain double-sided flexibility.
7. Quick turn rigid flex PCB design needs to consider the bending radius of flexible plate, too small bending radius will easily damage.
8. Quick turn rigid flex PCB design to effectively reduce the total area and reduce the cost.
9. Quick turn rigid flex PCB design to consider the structure of the three-dimensional space after installation.
Quick Turn Rigid Flex PCB Process Edge
The main reason for rigid flex PCB production of reserved technology edge is convenient for SMT machine to go over the track. Components too close to the track edge are prone to collision phenomenon and rigid flex PCB can not complete production. So quick turn rigid flex PCB in the process of assembled board production. In order to allow for subsequent patches and plug-ins, a process edge is generally added. quick turn rigid flex PCB's technology edge is about the increased part on both sides or four sides of rigid binding board for assisting SMT plug-in welding. It doesn't belong to rigid flex PCB, which can be removed after rigid flex PCB manufacturing.
Quick Turn Rigid Flex PCB Manufacturing Difficulties
1. The soft board material in quick turn rigid flex PCB is soft and thin, and the soft board must be carried over all horizontal lines with a traction board to avoid scrapping.
2. In the process of pressing PI covering film for quick turn rigid flex PCB, attention should be paid to local pasting of PI covering film and fast pressing parameters to avoid problems such as bubble holes.
3. Pay attention to the hard board windowing and PP in quick turn rigid flex PCB.
4. Quick turn rigid flex PCB compression inflation control.
