What Structures Can Be Used for Flexible Circuit Boards?

Adjustment Measures for Circuit Board Deformation

Reduce the impact of temperature on board stress by maintaining consistent and, if possible, lower soldering furnace temperatures to avoid surpassing the TG value.

Choose a thicker flexible PCB to prevent deformation during soldering, particularly when dealing with ultra-thin boards with a thickness below 1 millimeter.

Decrease the size of the flexible PCB to prevent an increase in weight and potential deformation in the middle. Keep the circuit board as compact as possible.

Refrain from using V-cut, as it may result in deformation of the flexible circuit board. It is advisable to avoid incorporating V-cut in the production process of flexible PCBs.
