Mycronic XWB3 ED-3B X Wagon Board L-029-0276-3B
Mycronic XWB3 ED-3B X Wagon Board L-029-0276-3B
This is an XWB3 (X Wagon Board 3) Edition 3B PCB assembly serving as the dedicated electronics control board mounted on or associated with the X-axis wagon (beam carriage) of Mycronic MY-series pick-and-place machines, providing local control and interface functions for all wagon-mounted components and subsystems.
Key characteristics:
- Application: Mycronic MY-series pick-and-place machines
- Function: Serves as the dedicated X wagon electronics interface board, providing local control, signal distribution, and communication for all components mounted on or connected to the X-axis wagon; responsibilities typically include:
- Interfacing and distributing control signals to wagon-mounted placement head motors and actuators
- Managing vacuum valve control signals for nozzle pickup and release
- Receiving and distributing encoder and position feedback signals from wagon-mounted transducers
- Interfacing with the X wagon camera vision system
- Managing wagon-mounted sensor inputs including nozzle presence, component detection, and head position sensors
- Providing local signal conditioning and buffering for wagon-mounted electronics
- Communicating with the main machine electronics rack via drag chain cable harness
- Manufacturer: Mycronic (L-prefix indicates a Mycronic assembly-level part number)
- Part number: L-029-0276-3B ("3B" denotes Edition 3B)
- Type: X wagon electronics interface PCB assembly
- Edition: 3B — specific hardware revision with defined firmware and compatibility requirements
- Category: Machine electronics / motion system component
- Criticality: High — failure of the XWB3 board typically results in loss of placement head control, vision system communication, or wagon-mounted sensor feedback, causing machine downtime
XWB3 in the Mycronic Electronics Architecture:
| Layer | Component | Function |
|---|---|---|
| Machine Control | MCB | Central machine controller |
| Motion Control | MOT3 Board | Axis motion coordination |
| Wagon Control | XWB3 Board | Local X wagon electronics interface |
| Execution | Head motors, valves, sensors | Physical placement operations |
Important Notes on Replacement:
- Edition matching is critical — verify Ed-3B compatibility with MCB and MOT3 board versions
- Drag chain cable harness connections should be inspected during replacement
- Full wagon functional verification including vision, vacuum, and head motion required after installation
- Engage Mycronic service support for post-installation configuration and verification

Lewis & Clark is a trusted global broker and service partner specializing in pre-owned SMT equipment, feeders, and machine parts. We help electronics manufacturers buy, sell, service, and support SMT assets throughout their entire lifecycle.
Our role goes far beyond simply brokering equipment — we act as a connector between buyers and sellers, a technical resource, and a long-term partner to customers across the PCB assembly industry.
SMT Equipment Brokerage
Lewis & Clark sources, evaluates, and sells pre-owned SMT equipment, including:
- Pick & Place machines
- Screen printers
- Reflow ovens
- AOI and SPI systems
- X-ray inspection equipment
- Inline and batch washers
- Flying probes
- Conveyors and automation
All equipment we sell is guaranteed to be 100% complete and operational, ensuring it can be installed and run on a customer’s production floor. If any components are missing or require replacement, we address those issues before shipment or as part of the sale.
What is Feeder Frenzy?
Through our sister company, Feeder Frenzy, we specialize in pre-owned SMT feeders, magazines, and spare parts. Customers can purchase these items directly through our online e-commerce platform, making it easy to find and order critical production components.
We support major SMT platforms including Mycronic, Universal Instruments, ASM/Siemens, FUJI, Panasonic and JUKI. All feeders and parts are authentic OEM-manufactured products and are backed by a 60-day warranty.
Professional Feeder Repair Services
Lewis & Clark provides professional SMT feeder repair and refurbishment services. Customers regularly send us anywhere from 5 to over 100 feeders at a time.
Our repair process includes:
- Individual feeder inspection
- Detailed repair estimates (labor + parts)
- OEM-quality repairs and testing
- Fast turnaround and clear communication
Every repaired feeder is returned fully tested and backed by a 60-day warranty.
Asset Purchasing & Equipment Sourcing
A major part of our business is buying SMT equipment, feeders, magazines, and parts from customers looking to sell surplus or idle assets.
We work directly with:
- Contract manufacturers
- OEMs
- End-users upgrading or consolidating production lines
- Facilities undergoing closures or relocations
Whether it’s a single machine, a feeder lot, or an entire SMT line, we provide fair market evaluations and streamlined transactions.
