In stock

Product Introduction:
The GE PWB68A993125 is a Printed Wiring Board (PWB) Assembly, which is the physical circuit board that forms the foundation of a GE Mark VIe control system module. Unlike the functional boards described earlier (which are complete products with their own part numbers), a PWB is the bare or populated circuit board that gets installed into a carrier or backplane. The “68A993125” is the specific part number for this board revision, which defines its component layout, trace routing, and connector positions. This PWB serves as the backbone for various I/O or communication modules, providing the electrical pathways that connect all the components together.

Technical Specifications:
Board Type: Printed Wiring Board Assembly (PWB)
Part Number: 68A993125
Layer Count: 8 to 12 layers (multi-layer PCB)
Material: FR-4 high-TG (glass transition temperature) epoxy laminate
Trace Width: 4 to 8 mils (fine pitch for high-density routing)
Connectors: High-reliability VIC bus connectors or mezzanine connectors
Surface Finish: ENIG (Electroless Nickel Immersion Gold) for corrosion resistance
Component Density: High-density surface mount (SMT) with through-hole components for power sections
Dimensions: Standard VIC Eurocard size (160mm x 233mm) or custom
Operating Temperature: -40 to 85 degrees Celsius (industrial grade)

Functional Features:
Multi-Layer Design: The 8-12 layer stackup provides dedicated layers for power, ground, and signal, minimizing crosstalk and electromagnetic interference.
High-Reliability Connectors: Uses gold-plated pins and locking mechanisms to ensure secure connection to the backplane, even in high-vibration environments.
Conformal Coating: Board is coated with a protective conformal coating to resist moisture, dust, and chemical exposure.
Impedance Control: Critical signal traces are impedance-controlled to ensure signal integrity at high frequencies.
Test Points: Includes test points for factory testing and field troubleshooting of individual signals.
Revision Tracking: The “68A993125” part number ensures traceability to a specific manufacturing batch and component lot.
