About Seprays
Founded in Taiwan(Genitec) in 1993, Seprays focuses on technological R&D and innovation. In 2002, it established a branch in Dongguan (which was upgraded and reorganized into a subsidiary in 2013), fully responsible for R&D, production, sales, and after-sales technical training services, ensuring rapid response and comprehensive support for customer needs. To further expand production, in 2003, it purchased nearly 20 acres of land in Zhejiang Province and established a 20,000-square-meter modern industrial plant, thereby increasing production capacity and manufacturing capabilities.
Seprays has been dedicated to the PCB/FPC depaneling field for over 30 years. Its main products include milling cutter depanelers, laser depanelers, V-groove depanelers, and stamping depanelers, as well as automated loading and unloading solutions for the front and rear ends of depaneling, including plate placement. It is a high-tech enterprise integrating R&D, production, sales, and service.
Seprays provides a complete line of equipment services to Fortune Global 500 and China’s Top 500 companies, including Foxconn, Flextronics, State Grid, Luxshare, Compal, Wistron, Bosch, China Electronics, Quanta Computer, CRRC Corporation Limited, China Aerospace Science and Technology Corporation, OPPO, and ZTE, as well as small and medium-sized enterprises. Seprays’ complete panel separation lines are widely used in factories both domestically and internationally.

Common PCB Depaneling Problems in SMT Production Lines
Common PCB depaneling problems in SMT production lines don’t usually show up at the start. The line runs. Output looks fine. But over time, small issues begin to affect yield, speed, and consistency. From an operator or process engineer’s point of view, these problems are familiar—and often underestimated. 🔍 Why Depaneling Becomes a Hidden Bottleneck Depaneling is typically the last mechanical step. It seems simple. Cut the board. Move it forward. But in reality, it directly impacts: When something goes wrong here, it affects everything downstream. ⚙️ Problem #1 — Mechanical Stress Damage This is one of the most common and most overlooked issues. Symptoms include: The challenge: These defects are often invisible at first. They appear later in testing—or
Fully Automatic PCB Depaneling Machines: Are They Worth It in 2026?
Fully automatic PCB depaneling machines are becoming a serious consideration in 2026. Not because they are new—but because production pressure has changed. Orders are increasing.But many depaneling processes still rely on manual handling. Frequent loading.Inconsistent output.Rising labor costs. These are no longer small inefficiencies.They are bottlenecks. So the real question is not “automation or not.”It’s whether your current process can keep up. 🔍 What “Fully Automatic” Really Means on the Line A fully automatic depaneling system typically includes: It runs continuously. With minimal manual intervention. The goal is simple: Stable, repeatable production. ⚙️ What Problems Automation Actually Solves From a user perspective, automation addresses real pain points: 1. Labor Dependency Manual loading creates: Automation reduces variability. 2. Production Interruptions Manual
Depaneling Solutions for BMS and Power Control Boards (EV Industry)
Depaneling solutions for BMS and power control boards are not just about separating PCBs. In EV manufacturing, they directly affect product safety, reliability, and long-term performance. If you’ve worked with battery management systems or power control modules, you already know: These boards are different. Thicker. Heavier. More sensitive to stress. 🔍 What Makes BMS and Power Boards So Challenging? From a user perspective, these PCBs typically have: They are used in: The challenge is simple: You must separate the board without introducing mechanical or thermal damage. ⚙️ Why Standard Depaneling Methods Often Fail Many factories initially use general-purpose methods. But for EV boards, problems quickly appear: 1. High Mechanical Stress 2. Poor Edge Quality 3. Low Efficiency 💥 Real Pain
Best PCB Depaneling Method for V-Cut and Mouse Bite Panels
Best PCB depaneling method for V-cut and mouse bite panels is not as straightforward as it looks. Many engineers assume one method is enough—until mixed designs start causing defects, stress cracks, or efficiency drops. V-cut and mouse bite in one PCB… how do you depanel it without damage? That’s where real process decisions begin. 🔍 Understanding V-Cut and Mouse Bite Panels Before choosing a method, it’s important to understand the difference. These two designs often appear together in modern PCBs. Especially in: ⚙️ Why Mixed Panels Create Real Problems When both V-cut and mouse bite exist in one panel, problems start to show. Typical issues: The core issue: Each design needs a different depaneling approach. 💥 What Happens If You
