Flexible printed circuits—commonly abbreviated as FPC or “flex circuits”—are valued for their light weight, thin profile, and ability to bend or fold freely. They are found in commercial electronics, automotive dashboards, fax machines, mobile phones, tablets, notebooks, and more. 

The key markets include:

• Automotive parts
• 3C electronics (computers, communications, consumer)
• Aerospace
• 5G & semiconductors
• Watches, jewelry, magnets
• Biomedical & medical-aesthetic devices

During automated assembly, singulating and feeding sheet-type FPCs is a critical process step. Correctly identifying the front vs. back side of each sheet and accurately placing it onto a mobile aluminum carrier directly affects final quality. Today, most plants still rely on manual loading: operators visually inspect each sheet and place it by hand. This approach yields low placement accuracy, drives up labor costs, and creates fatigue-related defects—ultimately reducing both yield and throughput. Moreover, the soft, irregular geometry of sheet FPCs has long made reliable automated feeding difficult, limiting overall factory-automation levels.

Danikor’s flexible vibratory bowl feeder—also called a flexible feeder, flexible feeding system, or flexible automatic feeder—solves these problems. Driven by multiple excitation motors, it is a highly adaptable, orientable feeding platform capable of handling parts ranging from millimetre-scale electronic components to irregular plastic or metal stampings. Its versatility makes it ideal for fast-changing product mixes and short product-life cycles, which is why it is already widely used in electronics, semiconductors, automotive electronics, and other smart-manufacturing lines.

Key advantages
• High speed, accurate positioning, and broad adaptability
• Eliminates manual handling defects: scratches, mixed boards, wrong parts, missing or extra parts, contamination
• Achieves fully automatic sheet-FPC loading: vision-guided singulation and orientation, robot placement into trays, boosting both productivity and first-pass yield

Technical highlights
• Three-axis vibration technology with up to eleven motion patterns gently tumbles sheet FPCs, minimizing damage.
• High-resolution CCD cameras integrated with vision-guidance software quickly identify part location and front/back orientation.
• Smart control software coordinates the hopper refill with the optimal vibration pattern, while four-axis robots or servo-driven Cartesian modules complete the final pick-and-place motion—solving the traditional pain points of fragile, irregular, two-sided FPC feeding.
