Product Name
Mark 8 IMC VME Connection Board
Product Introduction
This board is a VME interface and connection PCBA for the IMC architecture in TEL Mark 8 eight-inch track systems. It routes backplane control signals and data-bus communication across the VME card cage.
Detailed content
Technical Specifications
Manufacturer is Tokyo Electron. Part number is 1381-645294-12. System application is TEL Mark 8 eight-inch track. Subsystem is IMC VME card cage and backplane. Board type is connection or VME interface PCBA. Interface topology uses multipin VME backplane edge connectors. Recommended cleanroom enclosure environment is 15°C to 30°C, non-condensing.
Functional Features
The board provides high-density VME bus routing, multipin edge connectivity, signal continuity for slot-to-slot communication, and industrial noise suppression for track control traffic.
Application Scenarios
Use the board in Mark 8 VME racks for controller communication, backplane signal distribution, and IMC interfacing. It is intended for legacy eight-inch wafer track service where VME handshake errors or backplane faults are diagnosed.
Structural Characteristics
The assembly uses a multilayer VME-format printed circuit with edge connectors, multipin headers, and surface-mount components. Industrial shielding and trace layout support cleanroom electromagnetic conditions.
Working Principle
The VME backplane carries address, data, control, and power signals. The connection board distributes those signals to the assigned card cage slots and returns bus status to the system controller.
Installation Requirements
Install only in the compatible Mark 8 VME slot. Verify revision compatibility with existing IMC cards and rack software. De-energize the card cage before insertion. Inspect edge connectors and backplane pins before installation.
Usage Precautions
Do not hot-plug the board with active rack power. Seat the VME edge connector fully to prevent intermittent communication. Do not mix incompatible revision codes without system verification.
