Applied Materials 0100-01629 GF125CXXC – PCB Assembly for Mass Flow Controller | GF125C Platform
Engineering Background: The GF125C series Mass Flow Controllers (MFCs) are precision gas delivery components widely deployed in CVD, ALD, and etch process chambers across Applied Materials platforms including Centura, Producer, and Endura. The PCB Assembly (P/N 0100-01629) is the core electronic control board governing analog signal conditioning, valve drive, and flow calibration logic within the GF125CXXC variant configured for N₂ service at 280 SCCM full scale.
Product Positioning: This board is a direct OEM-equivalent replacement for field-failed or ESD-damaged control electronics in GF125CXXC MFCs. It restores full closed-loop flow accuracy without requiring full MFC replacement, significantly reducing downtime cost and spare-parts expenditure for fab maintenance teams.

System Architecture & Signal Flow
The GF125CXXC MFC operates on a closed-loop thermal mass flow measurement principle. The PCB Assembly (0100-01629) interfaces with the thermal sensor bridge, processes the differential voltage signal, compares it against the analog setpoint input (0–5 V), and drives the proportional solenoid valve to maintain the commanded flow rate. The board also provides diagnostic output signals compatible with standard MFC controllers and fab automation systems (SECS/GEM-compatible host interfaces via upstream MFC controller).

Technical FAQ
Q: Is this board compatible with both GF125C-102895 and GF125C-102896?
A: Yes. The 0100-01629 PCB Assembly covers both sub-variants. Verify your MFC label against the listed P/Ns before ordering.
Q: Does installation require MFC recalibration?
A: In most cases, no. The board retains the original calibration constants stored in the MFC body. However, we recommend a flow verification check post-installation per your fab SOP.
Q: Can this board be used for gases other than N₂?
A: This unit is calibrated for N₂ at 280 SCCM. Use with other gases requires recalibration by a qualified MFC service center.
Q: What warranty is provided?
A: 90-day functional warranty against DOA. Contact us within 72 hours of receipt for any claims.
