JEOL BP102150-00 Master Cont PB Card 886550050 172007-7 Electron Microscope

JEOL BP102150-00 Master Cont PB Card 886550050 172007-7 Electron Microscope Board

This is a JEOL Master Controller Printed Board (Master Cont PB) assembly, part number BP102150-00, also identified by part number 886550050 and board revision 172007-7. The board carries the internal description code "HSCAN CK PB" and reference number BOEBA577-03, consistent with a horizontal scan control or scan controller function within a JEOL electron microscope system. The PCB is a full-length parallel-bus card populated with a dense array of logic ICs and features a large multi-pin card edge connector along one side for integration into the microscope's backplane.

Applications

JEOL is a Japanese manufacturer of electron microscopes and related scientific instrumentation, producing scanning electron microscopes (SEMs), transmission electron microscopes (TEMs), and focused ion beam (FIB) systems used in semiconductor research, materials science, life science, and industrial quality control. Controller PCBs like this Master Cont PB card are core elements of the microscope's electronic control architecture, managing scan generation, signal routing, or system-level coordination depending on their specific function within the instrument. The HSCAN CK designation suggests this board is involved in the horizontal scan control chain — the circuitry responsible for driving the electron beam's raster scanning across the sample. These boards plug into the microscope's internal backplane and communicate with other subsystem cards. Replacement and spare controller boards for JEOL instruments are sought by research institutions, universities, semiconductor fabrication facilities, and specialized electron microscope repair and service shops maintaining aging JEOL systems.
