Rigid-Flex PWB for Automotive with high reliability

Product & Technology Product & Technology

Features

  • Semi-Flex PWB is that cutting a part of current rigid PWB in order to be more thin and can be used with bending. It's better to use for the equipment that doesn't need repetitive flexibility such as rigid PWB.
  • The connection reliability of TH is improved by changing the position of the bending layer from the center layer to the surface layer.
  • Applicable to high board thickness (1.6 mm) and double-sided PWB.

Application

  • For both of general and automotive products.
  • Equipment of structure mounted with bending.
