All-Polyimide Flex Circuits

All-Polyimide Flex Circuits

Fralock designs and manufacturers all-polyimide flex circuits for major OEM’s in technically
advanced markets such as aerospace and space-based applications. We provide single and multi-layer fine pitch flexible circuits where applications require interconnections in a compact package. Our flex circuits are smaller, lighter, and can seamlessly integrate into almost any form you need.  Fralock builds flex circuits to your exact specifications with predictable performance and high reliability Rigid-flex (a variation of flex circuits) combines a flex circuit with a rigid conductor such as a connector or a circuit board and can be found in applications ranging from consumer electronics to aircraft guidance systems. Defense and aerospace are the most common applications for rigid-flex as they are often the best way to reduce weight, and sometimes the only way to make a device feasible for the end application.

Application considerations may include:

  • Tightly assembled packages where electrical connections are required in 3 axes
    (static application)
  • Electrical connections where the assembly is required to flex during its use
    (dynamic application)
  • Weight sensitive applications such as hand held devices, airplanes or spacecraft
    where they replace heavier and bulkier wire harnesses
  • In space constrained applications that prohibit the use of thicker circuit boards or
    wire harnesses
  • High performance applications where heat or insulation requirements preclude
    typical insulation materials

Superior performance is achieved with Fralock flex circuits due to:

  • Adhesiveless construction results in more rugged, thinner, lighter and more flexible circuits
  • Higher density circuits: trace and space capabilities down to 0.003″ (may be limited according to size and scope)
  • Microvia sizes down to .001″ diameter for high density, 2-layer flex circuits
  • Selective plating of gold and tin leads enables multiple attachment methods on the same flexible circuit
  • Alternate circuit layer materials such as beryllium, copper, stainless steel, and nickel can be used for optimum performance in unique applications
  • Surface Mount Technology (SMT) and thru-hole assembly services. Package sizes down to 0201 and 0.4mm pitch
