About Seprays
Founded in Taiwan in 1993, Seprays focuses on technological R&D and innovation. In 2002, it established a branch in Dongguan (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 to 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, 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.
The company is ISO9001, ISO14001, and ISO45001 certified, holds CE certification, and owns over 100 hardware and software patents. It operates two modern factories covering over 26,000 square meters in mainland China and has service locations in nine cities across China, providing nationwide after-sales service. Sales and service locations in 31 countries worldwide provide timely customer service.

Moving forward together, creating extraordinary achievements | Seprays 2026 Team Building and 2025 Year-End Party successfully held
From January 31 to February 1, 2026, Seprays colleagues stepped away from daily routines and into the mountains, rivers, and—most importantly—into each other’s company. This two-day journey was more than a team-building activity or an annual meeting.It was a reflection on the past year, a shared experience as a team, and a quiet preparation for the year ahead. 🚍 Journey to Zhaoqing | Over a Hundred Colleagues, One Shared Departure On the morning of January 31, more than one hundred Seprays employees departed from Dongguan by bus, officially beginning our “Team Building + Annual Meeting” trip. By noon, we arrived in Zhaoqing. After lunch and a short break, everyone headed to Dinghu Mountain for free exploration. The mountain air was
Is inline PCB router depaneling worth it?
For some factories, it clearly is. For others, it becomes an expensive upgrade that never fully pays back. The real value depends less on the machine itself and more on how your SMT line actually runs day to day. This article looks at inline PCB router depaneling from a production-floor perspective—what problems it really solves, where it struggles, and when the investment makes sense. 🧩 What “inline” really changes Inline PCB router depaneling connects directly to the SMT line. Panels move automatically from reflow or AOI into depaneling without manual loading. What changes in practice: What doesn’t change: Inline doesn’t make routing magically faster—it makes the flow smoother. ⚠️ The pain points that push teams toward inline systems 👷 Labor
Is saw blade PCB depaneling faster than routing?
In most real production environments, yes—saw blade depaneling is usually faster, but speed alone rarely tells the full story. The better question engineers ask after a few projects is: faster for which boards, at what cost, and with what long-term risk? This article breaks the answer down from a production and reliability perspective. ⚡ Short answer first Speed matters—but only when it doesn’t compromise yield. 🧩 Where the speed difference really comes from 🔪 Cutting path length Saw blade depaneling follows straight, continuous lines. Once aligned, the blade cuts through the panel in a single motion. Routing removes material gradually, following programmed paths, which naturally takes longer. 🔄 Tool motion Routing involves frequent acceleration, deceleration, and direction changes. Saw blade
When Should You Choose Router Depaneling Instead of V-Cut?
Router depaneling vs V-cut is one of the most practical decisions PCB engineers face when balancing cost, quality, and long-term reliability. The short answer is simple: choose router depaneling when mechanical stress, design flexibility, and edge quality matter more than raw speed. Below, we break this down from real production experience—not theory. 🔍 What problem are engineers really trying to solve? Most depaneling issues don’t show up at the cutting stage. They appear later as: The depaneling method often becomes the hidden root cause. ⚙️ When V-cut starts to struggle ⚠️ High mechanical stress V-cut relies on the bending force to separate boards. This force travels through the entire PCB, not just the score line. For simple, low-density boards, this
