Types and Features of V-Groove PCB Depaneling Machines – And How to Choose the Right One

V-groove PCB depaneling is a common method used to separate pre-scored PCBs.
Choosing the right machine can significantly impact product quality, production speed, and equipment longevity.

In this article, we’ll break down the main types of V-groove PCB depaneling machines and what to consider when choosing the right one for your factory.

⚙️ Common Types of V-Groove PCB Depaneling Machines

🛠️ Moving-Blade Type

• Uses a rotary upper blade and a linear lower blade
• Produces very low stress, ideal for protecting solder joints
• Clean, burr-free edges—suitable for FR4 or component-loaded PCBs
• Comes with infrared safety curtains for operator protection

This is one of the most commonly used models across small to mid-volume electronics manufacturing.

✂️ Guillotine-Type (Straight-Blade)

• Dual pneumatic straight-blade design
• Cuts only short distances (≤2mm), reducing mechanical strain
• Ultra-low stress levels (down to 600μST)
• Works well with aluminum or copper-based boards
• Easy to operate, no training required

Perfect for high-hardness substrates and environments that prioritize simplicity.

💡 Multi-Blade Depaneling (for LED Strips)

• Equipped with six grouped blades for simultaneous multi-line cutting
• Reduces internal stress by 80%
• Prevents warping in aluminum-core PCBs
• Blade wobble <0.02mm, ensuring smooth, clean edges

A great choice for LED manufacturers or large-format light panel producers.

🧠 Seprays Featured Machines (For V-Scored Panels)

🔧 ZM30ASV / ZM300SV: Full-Automatic Online V-Groove Saw Depanelers

• Dual-direction cutting (X/Y axis)
• In-line conveyor system for unmanned operation
• Equipped with dust collection and quick-change blade modules

Ideal for high-throughput SMT lines that demand flexibility and cleanliness.

🎯 Vision-Based V-Groove Depaneling Machines

• Uses CCD vision correction for cutting accuracy (±0.05mm)
• Dual-table design enables simultaneous cutting and loading
• Great for applications that require tight tolerances and camera-based feedback

Recommended for precision electronics, such as mobile devices or automotive boards.

🔍 Other Depaneling Methods (For Comparison)

🌀 Router-Based Depaneling

• Seprays GAM386 represents this class
• Uses bottom-up milling, producing stress levels 1/100 that of manual snapping
• Best suited for boards with non-linear shapes or component-dense zones

🔬 Laser Depaneling

• High-end solution from Seprays
• Non-contact, zero-stress cutting
• No mechanical wear or blade changes required
• Ideal for ultra-thin or flexible PCBs

📌 How to Choose the Right Depaneling Machine

When selecting a V-groove PCB separator, consider:

1. Board type: FR4, aluminum, copper, or flex
2. Required throughput: Manual, semi-auto, or fully automated
3. Stress sensitivity: Will you be cutting near BGA, QFN, or LEDs?
4. Budget and scale: Consider long-term value, not just upfront cost
5. Precision level: Some applications require CCD-guided systems
6. Safety and cleanliness: Does your workspace need dust collection or noise reduction?
