INFORMATION & IDEAS
During soldering or assembly operations any stress to the conductor/pad interface can cause a fracture of the conductor.
Preventing isolated stress conditions critical to ensure no premature falilure will occur in flexibile circuit
Even though flex circuits are very pliable and flexible, there are limits to their flexibility.
This process is used on double sided (Type 2) circuits where maximum flexibility is desired.
The purpose of the fillet is to prevent conductors from being cracked when the circuit is flexed during installation.
Design options for covercoated pad hold down for single-sided and double-sided flex circuit applications
