The Siemens/ASM SIPLACE Feeder Ecosystem
The Siemens/ASM SIPLACE platform — now marketed under ASM Assembly Systems — has been a cornerstone of high-speed SMT placement for decades. From the SIPLACE X-series to the latest TX and SX platforms, ASM machines are known for their flexibility, speed, and the sophisticated feeder technology that enables both high-volume and high-mix production.
The SIPLACE feeder system is more than just a component delivery mechanism. With intelligent feeders that communicate bidirectionally with the machine, onboard memory for setup data, and integration with the ASM Works software platform, SIPLACE feeders are active participants in the smart factory. Managing them properly is essential for maintaining the placement quality and throughput that justifies the ASM investment.
SIPLACE Feeder Types
X-Series Tape Feeders
The X-series feeder family is the standard for current SIPLACE platforms. These intelligent feeders feature onboard memory, motor-driven tape transport, and automatic tape threading.
- Widths: 8mm through 88mm tape widths covered by the X-series family
- Intelligent features: unique feeder ID, pickup counter, maintenance counter, calibration data stored onboard
- Auto-threading: operator inserts the tape leader; the feeder automatically threads and positions the first component
- Splice support: detects and handles tape splices during production without operator intervention
Bulk Feeders
Bulk feeders handle loose components — typically large passives or components that arrive in bulk packaging rather than tape and reel.
- Capacity: holds hundreds to thousands of loose components in a hopper
- Presentation: mechanical or vibratory mechanism orients and presents components for pickup
- Best for: high-consumption passives where tape and reel costs are significant
Tray Feeders
SIPLACE tray feeders handle components in JEDEC-standard trays — typically large ICs, BGAs, and connectors.
- Multi-tray operation: tray changers hold multiple trays for extended unattended operation
- Precision positioning: mechanical alignment ensures accurate component pickup from tray pockets
- MSD sensitivity: tray components are frequently moisture-sensitive, requiring careful handling and storage
Odd-Form Feeders
Specialized feeders for non-standard components: connectors, switches, relays, and other through-hole or odd-shape parts that the SIPLACE platform can place.
- Custom tooling: often requires custom nozzles and pickup tooling matched to the component geometry
- Lower speed: odd-form placement is inherently slower than standard SMD placement
- Higher value: custom feeders and tooling represent a significant investment — proper storage and maintenance are essential to protect that investment
Storage Best Practices for SIPLACE Feeders
ESD Protection
SIPLACE intelligent feeders contain sophisticated electronics — motor controllers, memory chips, communication interfaces, and sensors. ESD damage can cause intermittent failures that are difficult to diagnose.
- Storage racks: ESD-dissipative or grounded conductive materials
- Handling protocol: ESD wrist straps mandatory when handling feeders
- Transport: use ESD-safe carts or containers when moving feeders between storage and production
- Static-generating materials: keep standard plastic bins, foam packaging, and non-ESD materials away from feeder storage areas
Environmental Conditions
- Temperature: 15-30°C (standard factory environment is acceptable)
- Humidity: below 60% RH to prevent contact corrosion. For feeders loaded with MSD components, store in controlled environment below 10% RH.
- Dust and particulates: minimize exposure — dust in tape paths and on contacts is a leading cause of feed errors and communication failures
Physical Storage Organization
A well-organized feeder storage area should support fast identification, safe handling, and clear status indication:
- Dedicated slots: each feeder has an assigned storage position, labeled with the feeder ID
- Status indication: visual system showing feeder status (available, loaded, needs maintenance, calibration due)
- Width grouping: organize feeders by tape width for fast selection during setup
- Maintenance separation: feeders awaiting maintenance stored separately from production-ready feeders to prevent accidental use
Calibration Procedures
Why Calibration Matters
SIPLACE machines achieve placement accuracy of ±25μm or better. This precision requires that every feeder presents components at exactly the expected position. Calibration drift — even by fractions of a millimeter — can cause pickup failures, recognition errors, and placement offset.
Calibration Types
- Feeder position calibration: verifies the X/Y position where the feeder presents the component to the nozzle. Run during initial feeder installation and after any mechanical service.
- Pickup height calibration: verifies the Z-axis height at which the component is presented. Critical for small components (0402, 0201) where height tolerance is tight.
- Tape advance calibration: verifies that the tape advances the correct pitch distance to present each pocket accurately.
Calibration Schedule
| Trigger | Calibration Type |
|---|---|
| New feeder (first use) | Full calibration (position, height, advance) |
| After mechanical service or repair | Full calibration |
| After dropping or physical impact | Full calibration |
| Every 500,000 picks (or per ASM recommendation) | Verification calibration |
| Persistent pickup failures on a specific feeder | Targeted calibration of the affected feeder |
| Quarterly audit | Spot-check calibration of random fleet sample (10-20%) |
Common SIPLACE Feeder Issues and Solutions
| Issue | Likely Cause | Resolution |
|---|---|---|
| Feeder not recognized by machine | Dirty contacts, firmware mismatch, damaged connector pins | Clean contacts with appropriate contact cleaner; update firmware; inspect connector |
| Repeated pickup failures | Calibration drift, worn nozzle, tape positioning error | Recalibrate feeder; replace nozzle; verify tape threading |
| Tape jam during production | Debris in feed path, damaged sprocket, poor splice | Clear debris; inspect sprocket teeth; redo splice following ASM guidelines |
| Auto-thread failure | Tape leader not positioned correctly, mechanism worn | Reposition tape leader; clean threading mechanism; service if persistent |
| Intermittent communication errors | ESD damage, oxidized contacts, loose connection | Clean contacts; verify seating; replace feeder if errors persist (possible ESD damage) |
| Cover tape peeling inconsistently | Peel mechanism worn, adhesive buildup, incompatible tape brand | Clean peel path; replace wear parts; verify tape compatibility |
Feeder Lifecycle Management
Lifecycle Stages
- Commissioning: new feeder received, initial calibration, entered into tracking system
- Active production: regular use with scheduled maintenance
- Heavy use / approaching service interval: increased monitoring, scheduled for preventive service
- Service / rebuild: worn parts replaced, full recalibration
- End of life: performance no longer meets specifications after service, retired from production
Replacement Planning
SIPLACE feeders represent a significant per-unit investment. Plan replacement based on data, not on failure:
- Track error rate per feeder over time: feeders with rising error rates despite maintenance are approaching end of life
- Monitor calibration drift: feeders that require increasingly frequent recalibration are wearing mechanically
- Budget for fleet renewal: plan to replace 5-10% of your feeder fleet annually to maintain quality
- Keep spare capacity: maintain enough spare feeders that a single feeder failure does not disrupt production
Integration with ASM Works
ASM Works software provides comprehensive feeder management within the SIPLACE ecosystem:
- Feeder database: central record of all feeders, their current status, location, and history
- Setup optimization: ASM Works calculates optimal feeder assignments to minimize changeover scope
- Maintenance alerts: automatic notifications when feeders reach maintenance intervals
- Usage analytics: fleet utilization data for capacity planning and replacement budgeting
For factories that also use intelligent storage systems for component reels, connecting the feeder management data from ASM Works with the material data from the storage system creates a complete picture: you know not just which component is on which feeder, but where that feeder is stored, when it was last calibrated, and how many picks it has accumulated.
How Smart Storage Systems Complement Feeder Management
Intelligent storage systems like the Neotel SMD BOX manage the component reels that feeders consume. The intersection of feeder management and material management creates opportunities for optimization:
Pre-Staged Materials for Offline Setup
When the storage system knows the next job’s BOM and feeder assignments, it can retrieve all required reels in the correct sequence for loading onto offline feeder trolleys. The operator receives reels in feeder-slot order — no sorting, no searching.
Reel Exhaustion Prediction
By combining the storage system’s remaining-quantity data with the machine’s consumption rate, the system predicts when each reel on a feeder will run out and pre-stages the replacement. The new reel is waiting at the output port before the operator needs it.
MSD Compliance for Loaded Feeders
When a reel is loaded onto a feeder and taken out of controlled storage, its floor life clock is running. The storage system tracks when the reel was issued and calculates remaining floor life. If a loaded feeder sits unused beyond the component’s floor life, the system alerts the operator before the feeder is used in production.
Setup Optimization: Reducing Feeder Preparation Time
Common Table Optimization
ASM Works can calculate a common feeder table — a set of feeder positions that remain constant across multiple product variants. Components common to several products stay loaded, and only product-specific positions change during changeover. This reduces both the number of feeders that need to be swapped and the material retrieval required from storage.
Feeder Cart Strategy
- Dedicated carts per product family: pre-loaded carts that can be swapped in minutes
- Shared carts with common components: components used across families stay on the cart permanently
- Spare carts: always one spare cart per line being prepared offline for the next changeover
Maintenance Best Practices Checklist
