[Tweet](https://twitter.com/share) At first glance, the answer to the question “How many layers can a [flexible circuit](https://www.epectec.com/flex/) have before it can no longer bend?” sounds like a simple, black-and-white answer. However, this answer proves to be more complex than expected and involves a great deal of specifications before it can be answered.
