The industry acceptance and growth of
bulk feeding will present a win-win-win
opportunity for all three parties...
• Component suppliers
• Equipment (machine/feeder) suppliers
• Customers/users (OEM and CEM)

Key Bulk Feeding Drivers
Component Geometry Standards
(right now, there are none)
Improved feeder designs
(right now, there are many different ones)
Higher machine utilization
Issue resolution
(right now, can be good.. or bad)
(flipped resistor, component damage)
Success with Bulk Feeding
(depends on previous drivers)

Benefits of Bulk Feeding
• Improved machine utilization
– Faster / easier component replenishment
– Increased line throughput
– less maintenance
• Increased factory capacity
– Higher on-line component count
• Reduced cost
– storage / transportation
– direct labor / material handling
– component (unit)
• Better for the environment (tape waste, etc.)
– recycling opportunities
• Better board quality (cleaner process)
– solder joints
• Lower component attrition rates
• Better pick/placement accuracy

Issues & Barriers
PROCESS ISSUES
• Resistors can be placed upside-down
• Component polarity
• Learning curve for production staff
• Component verification / validation
PRODUCTION ISSUES
• Feeder jams
• Component quantity per package
• Two part numbers (tape & bulk)
• Mixing components in the feeder
• Some CEM customers will not supply
(consign) bulk parts
• Component availability / limited suppliers
• Bulk handling capability varies, vendor by
vendor
FEEDER DESIGN ISSUES
• Design template
• Feeder track dimension tolerance
• Speed
• Reliability
• Ability to handle resistor chips
• Short mean-time to repair (clear a jam)
• Machine upgrade / investment costs
COMPONENT ISSUES
• Dimensional tolerances / standardized
geometry
• Component damage
• Bulk component cost (versus taped parts)
• Standardized packaging (case, bag, etc.)

Bulk Feeding Summit Group
Consists of:
• Component suppliers
• Equipment suppliers
• Users (OEM & CEM)
Goals:
• To agree on standards
– component dimensions & tolerances
– packaging (case, bag, hopper, etc.)
• To develop supporting documents
– “best practices” (to avoid component damage, optimize
performance, etc.)
– study/report focusing on the resistor “upside-down” issue
– study/report focusing on the effect of moving & vibration on bulk
fed components
