When you begin learning about flexible printed circuit boards, you’ll discover that there are several different types of flex circuits. The most well-known and most used are:
One type of flexible circuit you may not have heard about before is the sculptured flex circuit. What is this type of circuit, and how can it be used? Sculptured flex circuits are relatively rare and are distinguished by a unique multi-step etching process that results in copper conductors that have a varied thickness across the circuitry pattern.
This allows the circuit to have a thicker copper trace in the areas that require a higher structural strength or where the current is strongest. The thinner parts of the trace help the circuit maintain its flexibility. One big benefit of the sculptured flex circuit is that its built-in contacts eliminate the need for additional connectors. This can save weight, space, assembly labor, and product costs.
