Type 1 Single-Sided Flex

Single-Sided Flex
  • Single-Sided flex, or Type 1 Flex, is a flex circuit based on one conductive layer of copper
  • Ease of manufacturing or assembly
  • Single-Sided circuits are ideal for dynamic or high-flex applications
  • Silver shielding can be added for EMI protection
  • Stiffeners can be added to “ruggedize” connection areas
  • These types of circuits are very cost effective in replacing low-high volume simple wire harnesses
  • Ease of assembly as circuit 1 and 1,000 are built with the same tooling guaranteeing reproducibility
  • Military and IPC Specification qualified

Type 2 Double-Sided Flex

Single-Sided Flex
  • Double-Sided, or Type 2 Flex, is a flex circuit based on two conductive layers of copper that are interconnected through Plated-Through-Holes (PTH’s) or Via’s creating electrically active circuitry on both conductive layers
  • Worlds most popular flex circuit design
  • Ease of manufacturing or assembly
  • Through holes are “supported” as they are plated through creating a more reliable solder-joint
  • Silver shielding can be added for EMI protection
  • Stiffeners can be added to “ruggedize” connection areas
  • “Button Plating” or Pads only plating is a method when copper plating a circuit that must maximize it’s flexibility in it’s end application
  • The ability to plate to a ground plane with one conductor layer is a good cost effective way for stripline impedance
  • Cost effective and light weight
  • Ease of assembly as circuit 1 and 1,000 are built with the same tooling guaranteeing reproducibility
  • Military and IPC Specification qualified

Type 3 Multi-Layer Flex

Single-Sided Flex
  • A circuits consisting of more than two copper conductor layers (typically less than 10) that are interconnected through Plated-Through-Holes (PTH’s) or Via’s creating electrically active circuitry on all conductor layers
  • As connectors get more dense more conductors need to be routed in a small area, this is where a multi-layer approach is required
  • A four layer circuit (two active layers and two ground planes) are a very common construction for 100-ohm differential impedance pairings
  • Through holes are “supported” as they are plated through creating a more reliable solder-joint
  • Internal Copper ground planes are a great way to achieve electrical isolation
  • Stiffeners can be added to “ruggedize” connection areas
  • “Button Plating” or Pads only plating is a method when copper plating a circuit that must maximize it’s flexibility
  • Cost effective and light weight
  • Ease of assembly as circuit 1 and 1,000 are built with the same tooling guaranteeing reproducibility
  • Military and IPC Specification qualified

Type 4 Rigid Flex

Single-Sided Flex
  • A circuits consisting of more than two copper conductor layers that are interconnected through Plated-Through-Holes (PTH’s) or Via’s creating electrically active circuitry on all conductor layers. The flexible layers are integral to the “rigidized” layers and both the PTH’s or Via’s are plated through the rigid and flex areas.
  • As connectors get more dense more conductors need to be routed in a small area, this is where a multi-layer approach is required
  • Through holes are “supported” as they are plated through creating a more reliable solder-joint
  • Internal Copper ground planes are a great way to achieve electrical isolation
  • Stiffeners can be added to “ruggedize” connection areas
  • Blind and or Buried -via’s are options to create more density therefore allowing more functionality to be designed into the Rigid-Flex
  • Cost effective and light weight
  • Ease of assembly as circuit 1 and 1,000 are built with the same tooling guaranteeing reproducibility
  • By incorporating PCB and Flex into one design there are less points of failure as well as creating a smaller interconnect area
  • Military and IPC Specification qualified

Type 4 Rigid Flex Book-Binder

Single-Sided Flex
  • A circuits consisting of more than two copper conductor layers that are interconnected through Plated-Through-Holes (PTH’s) or Via’s creating electrically active circuitry on all conductor layers. The flexible layers are integral to the “rigidized” layers and both the PTH’s or Via’s are plated through the rigid and flex areas; the flex-layers are built with a controlled progression to enhance flexibility.
  • The ability to build a high-layer count Rigid Flex and still meet the needs of a tight bend radius
  • As connectors get more dense more conductors need to be routed in a small area, this is where a multi-layer approach is required
  • Through holes are “supported” as they are plated through creating a more reliable solder-joint
  • Internal Copper ground planes are a great way to achieve electrical isolation
  • Stiffeners can be added to “ruggedize” connection areas
  • Blind and or Buried-via’s are options to create more density therefore allowing more functionality to be designed into the Rigid-Flex
  • Cost effective and light weight
  • Ease of assembly as circuit 1 and 1,000 are built with the same tooling guaranteeing reproducibility
  • By incorporating PCB and Flex into one design there are less points of failure as well as creating a smaller interconnect area
  • Military and IPC Specification qualified
  • Short Bend Radius
