First, a flexible circuit design must work in the appli- cation as designed and be cost-effective so the end product can be sold or used. What drives a designer to choose between an etched copper circuit, printed ink, flat flexible cable, die-cut copper, or die-cut aluminum? Multiple factors influence the design. Unfortunately, limited knowledge or experience can prevent designers from considering alterna- tives because they may not know the design rules, limitations, or capability limits of each option. As a result, they often stay with what is known and proven, missing opportunities to reduce cost or provide another option to quote. At this stage, several factors should be consid- ered when determining how the flexible circuit should be designed: Functionality: What electrical connections are required? Does the circuit need to support switching, sensing, lighting, components, or a full schematic? Are there high-speed, shielding, imped- ance, or resistance requirements? Component requirements: Does the design require LEDs, sensors, switches, or SMT compo- nents? How will they be attached? Are soldering or conductive epoxy required? Temperature limits: What temperatures must Is a Printed Silver Ink Circuit Right for Your Application?
