Flex PCB Manufacturing Process
- Substrate Preparation: Flexible material (polyimide or polyester) coated with adhesive and cured
- Copper Cladding: Thin copper layer applied via electroplating or lamination
- Circuit Patterning: Selective copper etching using photolithography or laser ablation
- Layer Bonding: Multilayer flex PCBs are stacked and bonded with adhesive
- Drilling and Plating: Holes drilled and plated for component mounting/interconnection
- Surface Finishing: Copper surfaces coated with protective finishes
- Component Assembly: Components mounted using SMT or THT technology
- Testing and Inspection: Rigorous quality control for functionality assurance
Types of Flex PCBs
- Single-sided Flex PCB: Single conductive layer design
- Double-sided Flex PCB: Conductive layers on both sides with PTH interconnections
- Multilayer Flex PCB: Three or more conductive layers with insulating layers
- Rigid-Flex PCB: Hybrid construction combining flexible and rigid sections
Rigid-Flex PCB Circuits
Rigid-flex circuits feature a hybrid construction with laminated flexible and rigid substrates forming a single structure. Unlike stiffened flex circuits, rigid-flex designs incorporate both rigid and flexible areas with plated through holes for electrical interconnection between layers.
Originally popular in military applications, rigid-flex technology has expanded to commercial products including laptop computers, where it's commonly used for display cables requiring thousands of flexures during product lifespan.
FPC Manufacturing
Flexible printed circuits (FPC) are manufactured using photolithographic technology, offering advantages in applications requiring:
- 3-axis electrical connections in tight assemblies (e.g., cameras)
- Dynamic flexing during normal use (e.g., folding cell phones)
- Space-constrained environments where traditional wire harnesses are impractical
- Applications where board thickness is a critical factor
Single-Sided Flex PCB Circuits
Featuring a single conductor layer on flexible dielectric film, these circuits allow component termination from one side only. Protective coatings are typically applied, though transparent LED films using sputtered conductive films represent a specialized application of this technology.
Double-Sided Flex PCB Circuits
With two conductor layers typically connected by plated through holes, these circuits enable component placement on both sides. The double-sided construction simplifies crossover connections while maintaining flexibility, commonly used in applications like laptop mousepad connections.
Multilayer Flex PCB Circuits
Containing three or more conductor layers, multilayer flex circuits may use discontinuous lamination in areas requiring maximum flexibility. Layer interconnection is typically achieved through plated through holes, with construction tailored to balance circuit complexity with mechanical flexibility requirements.
