INFORMATION & IDEAS
DESIGN TIP: Pad Only Plating
This process is used on double sided (Type 2) circuits where maximum flexibility is desired.
DESIGN TIP: Epoxy Resin Fillets
The purpose of the fillet is to prevent conductors from being cracked when the circuit is flexed during installation.
DESIGN TIP: Minimum Bend Radius for Flex Circuits
Even though flex circuits are very pliable and flexible, there are limits to their flexibility.
DESIGN TIP: Need for Anchoring Spurs and Pad Fillets
During soldering or assembly operations any stress to the conductor/pad interface can cause a fracture of the conductor.
DESIGN TIP: Balanced Circuit Pattern Reduces Premature Failure
Preventing isolated stress conditions critical to ensure no premature falilure will occur in flexibile circuit
DESIGN TIP: Pad Hold Down Options
Design options for covercoated pad hold down for single-sided and double-sided flex circuit applications
