Product Details

SEC-4400, 5000 SCCM, SEC-4400 SGDV-OCB01A SGDV-2R8AE1A 410126-711 Product Description

The STEC SEC-4400 is a high-precision, energy-control mass flow controller from the renowned SEC Series, engineered for demanding semiconductor fabrication, chemical vapor deposition (CVD), and advanced industrial process environments. Rated at 5,000 SCCM, the SEC-4400 delivers stable, repeatable gas flow regulation with minimal thermal drift, directly contributing to reduced energy waste, lower heat load on process chambers, and optimized production line throughput. Whether integrated into a new smart factory build or retrofitted into an existing automation architecture, the SEC-4400 is a cornerstone component for energy-aware process control.

In a fully integrated smart production line, the STEC SEC-4400 does not operate in isolation — it functions as a precision node within a broader energy management and process control ecosystem. When paired with a Mitsubishi MELSEC Q-Series PLC or a Siemens S7-300 programmable logic controller, the SEC-4400 receives real-time setpoint commands via analog signal (0–5 VDC or 4–20 mA), enabling dynamic flow adjustment in response to recipe changes or process deviations without manual intervention.

For facilities running multi-zone gas distribution, the SEC-4400 integrates seamlessly alongside STEC SEC-4100 and STEC SEC-4200 controllers within the same SEC Series platform, allowing engineers to standardize calibration procedures, spare parts inventory, and maintenance schedules across the entire gas panel. This uniformity reduces operational overhead and minimizes unplanned downtime.

On the power monitoring side, the SEC-4400 can be deployed in conjunction with Yokogawa WT series power analyzers or Hioki PW3390 power meters to correlate gas flow consumption with electrical energy draw at the process chamber level. This data feeds directly into SCADA platforms such as Wonderware InTouch or Ignition, where energy KPIs are tracked in real time and anomalies trigger automated alerts before they escalate into yield-impacting events.

For facilities using Yaskawa SGDV-2R8AE1A Sigma-5 servo drives or SGDV-OCB01A communication option cards — components already associated with this SEC-4400 unit — the integration extends to coordinated motion and flow control, where servo-driven valve actuators and MFC setpoints are synchronized through a shared MECHATROLINK-II or EtherCAT network. This tight coupling eliminates latency between mechanical positioning and gas delivery, reducing transient over-flow events that waste process gas and energy.

Omron NX-series I/O modules and Keyence SR-series barcode readers on the production line further enhance traceability, ensuring each wafer lot processed under SEC-4400 control is logged with its corresponding flow profile for quality assurance and energy audit purposes. An HMI panel — such as a Proface GP4000 or Siemens TP700 Comfort — provides operators with a real-time dashboard of flow rates, setpoint deviations, and cumulative gas consumption, empowering line supervisors to make informed energy-saving decisions without interrupting production.

Uncontrolled or imprecise gas flow is one of the most overlooked sources of energy waste in semiconductor and specialty chemical manufacturing. Excess flow not only consumes more process gas — a significant direct cost — but also increases the thermal load on exhaust treatment systems, vacuum pumps, and abatement units, all of which draw additional electrical power. The STEC SEC-4400 addresses this at the source by maintaining flow accuracy within ±1% of full scale, ensuring that every SCCM delivered to the process chamber is intentional and productive.

In multi-step deposition or etch processes, the SEC-4400's fast response time (under 2 seconds to setpoint) enables tighter recipe control between process steps, reducing the inter-step purge time that is typically wasted as non-productive gas consumption. Over a 24/7 production schedule, this translates into measurable reductions in specialty gas procurement costs and lower load on gas abatement systems.

From a predictive maintenance perspective, the SEC-4400's stable analog output signal provides a continuous health indicator. Drift in the output — detectable by the connected SCADA or APC system — serves as an early warning of valve wear or sensor degradation, allowing maintenance teams to schedule replacement during planned downtime rather than reacting to unplanned failures. This proactive approach directly improves equipment utilization rates and sustains production line rhythm (takt time) without energy-intensive emergency recovery procedures.

All STEC SEC-4400 units supplied by NANKMOS are sourced from verified inventory, subjected to pre-shipment functional testing, and backed by a 12-month warranty. Stock is maintained for rapid global dispatch, minimizing lead time for both new installations and emergency replacement scenarios.

Q1: How does the STEC SEC-4400 contribute to energy savings in a semiconductor fab? The SEC-4400 maintains gas flow within ±1% F.S. accuracy, eliminating over-flow waste that increases process gas consumption and thermal load on downstream abatement and vacuum systems. Tighter flow control also shortens inter-step purge cycles, reducing non-productive energy consumption across each production shift.

Q2: Is the SEC-4400 compatible with existing PLC and SCADA control architectures? Yes. The SEC-4400 uses standard analog interfaces (0–5 VDC / 4–20 mA) compatible with most PLC platforms including Mitsubishi MELSEC, Siemens S7, and Allen-Bradley ControlLogix series. It can be integrated into SCADA systems such as Ignition or Wonderware for centralized energy monitoring and recipe management.

Q3: What is the recommended replacement or upgrade path from an older MFC model? The SEC-4400 is a direct form-factor and interface replacement for earlier STEC SEC-Series controllers. For facilities upgrading from SEC-4100 or SEC-4200 units, no gas panel re-piping is required — only setpoint calibration and functional verification are needed before returning the line to production.

Q4: What testing and warranty coverage does NANKMOS provide? Every STEC SEC-4400 unit is functionally tested prior to shipment to verify flow accuracy, valve response, and signal integrity. All units are covered by a 12-month warranty from the date of delivery. NANKMOS maintains ready stock for fast global shipping, and our technical team supports installation verification and commissioning guidance upon request.
