Latest price list of Interlock used in electronics factory

1. Interlock System - The "Gatekeeper" of Electronic Cleanrooms

In electronic manufacturing environments, especially SMT (Surface Mount Technology) lines, cleanrooms are not only mandatory to protect sensitive components from dust and static electricity, but also essential for controlling airflow and pressure between zones.

Cleanroom interlock systems serve as critical “gatekeepers” that help ensure:

• Only one door opens at a time, preventing cross-contamination between zones with different cleanliness levels.
• Pressure differentials are maintained to direct clean airflow properly.
• Cross-contamination from personnel, materials, or equipment is minimized when passing through airlocks or sensitive areas.

In practice, many incidents involving dust particle contamination, ESD damage, or component failure stem from seemingly minor door control issues - problems that a well-designed electronic interlock system can completely prevent.

Why are electronics factories racing to install interlock systems?

Vietnam’s electronics sector is rapidly expanding, with new factories producing chips, PCBs, and advanced technology devices. This growth drives the need to upgrade cleanroom infrastructure, particularly:

• Adding airlocks, gowning rooms, and ESD weighing rooms
• Upgrading from mechanical doors to smart interlock systems
• Integrating pressure monitoring, door status indicators, and central control units

As a result, understanding and updating interlock pricing has become a practical necessity for maintenance managers, cleanroom engineers, and HVAC/cleanroom system consultants.

2. Key Factors Affecting Cleanroom Interlock System Pricing

On today’s market, the price of cleanroom interlock systems can range from a few million to tens of millions of VND, depending on configuration and technical requirements. To select the right system for your budget and operational needs, it’s essential to understand the main factors influencing the cost:

1. Type of Interlock System: Mechanical - Electronic - Smart Sensor-Based

• Mechanical interlock: Operates with a basic mechanical latch, typically used for basic 2-door systems. It is cost-effective but lacks expandability or logic control.
• Electronic interlock: Uses electrical signals to control door locking/unlocking. These can be integrated into centralized systems and are well-suited for modern cleanrooms.
• Sensor-based smart interlock: Allows for flexible scenario programming (e.g., only opens when pressure differential is correct). Commonly used in SMT lines requiring high precision.

2. Number of Interlocked Doors: 2 - 3 - Multi-door Systems

• 2-door systems: The most common setup for basic airlocks.
• 3-door systems: Ideal for gowning rooms or areas with multiple material/personnel flows.
• Multi-door systems (4-6 doors or more): Require a central control unit and logic management software. These setups are more complex and therefore more expensive.

3. Additional Features

• Audible alarms & door status indicators: Help users easily identify whether a door is open or locked.
• Touchscreen control panels: Allow for intuitive programming and real-time display of door status.
• Pressure differential monitoring & fault alerts: Enhance safety in sensitive production zones.

4. Component Origin & Compliance with Technical Standards

• Imported components from Germany, Japan, or South Korea offer higher durability and precision, but at a higher cost than domestic options.
• Compliance with cleanroom standards such as ISO 14644-1, ESD, or GMP also affects pricing due to certification and specialized design requirements.

Conclusion:

When comparing interlock system quotes, don’t just look at the final price - evaluate the full picture: intended use, integration level, and scalability. Choosing the right configuration from the start will save you considerable upgrade costs in the long run.

4. Recommendations for Choosing Interlock Systems by Area in Electronics Factories

Selecting the right type of interlock system not only ensures optimal environmental control but also helps manage investment costs effectively across different zones of an electronics facility. Below are practical recommendations for key functional areas:

SMT Area - Surface Mount Technology Lines

• Environmental Impact: Requires strict control of dust, static electricity, and pressure differentials.
• Recommended Lock: 2-door electronic interlock system with sensors and precise logic control.
• Why: Prevents simultaneous door openings, protecting sensitive components from particle exposure or static discharge.
• Recommended Models: VCR‑X2M, SM2‑861S.

Gowning Room - Transition Area to Cleanroom

• Environmental Impact: Serves as a buffer between external environments and cleanroom zones; high risk of cross-contamination.
• Recommended Lock: 3-door interlock system with status indicators and alarm notifications.
• Why: Ensures one-way flow and compliance with gowning, handwashing, and sanitization protocols.
• Recommended Models: VCR‑X3S, SM3C.

ESD-Sensitive Weighing Room (ICs, PCBs, Chips)

• Environmental Impact: Components are highly sensitive to ESD; require complete isolation and controlled access.
• Recommended Lock: Electronic interlock system with ESD access control (grounding verification).
• Why: Restricts access to only ESD-compliant personnel, integrates with ESD testers or touchscreens.
• Recommended Models: SM2T, customized systems with ESD control.

Tip for Selecting the Right System: Always base your decision on your cleanroom layout and actual operating procedures. VCR offers free consultations and layout-based interlock design support tailored to each production line.

6. FAQ - Quick Answers About Cleanroom Interlock Systems

1. Do electronic interlock systems require regular maintenance?

Yes. To ensure stable operation and synchronization between doors, maintenance should be performed at least every 6 months. This includes checking the power supply, control signals, magnetic locks, and any built-in alarm or indicator functions.

2. Can a mechanical interlock system be upgraded to an electronic one?

Absolutely. However, it requires an assessment of your current setup, including:

• Distance between doors
• Concealed or surface-mounted wiring system
• Available power supply

VCR can assist in redesigning the interlock layout and provide the right conversion kit without replacing the entire system.

3. How long is the delivery time after placing an order?

Standard delivery time is 3-5 working days. Popular models like VCR-X2S or SM2T are often available in stock in Hanoi and Ho Chi Minh City, so they may ship sooner for domestic orders. Custom or multi-door systems may take 7-10 days to deliver.
