flex circuits

Flex Circuits, RIGID-FLEX Capabilities

Flex circuits are fully surface mountable to accommodate: surface mount, chip-on-flex, as well as flip-chip technology. Our strategic partnerships give you the benefits you'd expect from our flex circuits manufacturing team, and you can be rest assured your flex circuits or Rigid-Flex circuit products will be of premium quality.

Flex circuits are commonly used in many applications spanning many markets including today's: wearable products, consumer electronics, medical devices, military, and aerospace. Common applications include: laptop computers, ink jet printers, hard disk drives, optical storage drives, cellular phones, video tape recorders, flat panel displays, etc.
