BULK COMPONENT FEEDING • Key drivers • User benefits • Issues & Barriers – – – – Process Production environment Feeder designs Components • Industry effort (Bulk Feeding Summit Group) • Bulk feeding methods • Universal bulk feeding solutions – GSM – HSP Bulk Feeding Solutions Page 1 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) Bulk Feeding Solutions Page 2 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) Bulk Feeding Solutions Page 3 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 Bulk Feeding Solutions Page 4 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 Solutions Page 5 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 Bulk Feeding Solutions Page 6 HSP Bulk Feeder Development Status (April 1999) Component Type Feeder Status 0201C Preliminary development has begun 0201R No development activity at this time 0402C Available P/N 46794110 0402R Prototypes are being tested 0603C Available P/N 46794111 0603R Prototypes are being tested 0805C (0.6t) Available P/N 46794112 0805C (1.25t) Available P/N 46794113 0805R No development activity at this time Bulk Feeding Solutions Page 7
