Abstract
A stretchable circuit board assembly and a method for manufacturing the same are provided. The circuit board assembly includes a flexible circuit board and an outer circuit board. The flexible circuit board includes a first base layer and an inner wiring layer. The flexible circuit board is divided into a connecting area and a stretchable area. The inner wiring layer within the connecting area includes an electrical connecting portion exposed from the outer circuit board. The stretchable area is configured to deform into at least one bent portion. The bent portion is used to cause the electrical connecting portion to stretch relative to the outer circuit board. The outer circuit board includes a second base layer and an outer wiring layer. A surface of the second base layer away from the outer wiring layer defines at least one blind groove. The blind groove is configured to receive the bent portion.
