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.

PCB Depaneling Insights & Manufacturing News
What Problems Can Saw Blade PCB Depaneling Solve in SMT Manufacturing?
What Problems Can Saw Blade PCB Depaneling Solve in SMT Manufacturing? It’s a question that often comes up when production lines start pushing for higher output but run into bottlenecks at the depaneling stage. In real factory environments, the issue is rarely about technology alone—it’s about stability, cost, and keeping the line moving. 🔍 The Hidden Bottleneck in SMT Lines In SMT manufacturing, most attention goes to placement accuracy and reflow quality. But once boards come off the line, depaneling becomes the next critical step. Common issues include: Saw blade depaneling addresses these problems with a straightforward approach. It keeps things predictable. ⚙️ Solving Throughput Pressure High-volume SMT lines don’t wait. If depaneling can’t keep up, everything backs up. Saw
Why Saw Blade Depaneling Is Common in Mass PCB Production
Saw blade depaneling is one of those processes that rarely gets the spotlight, yet it quietly supports high-volume PCB manufacturing every day. If you’ve ever dealt with tight production schedules or cost pressure, you’ve probably seen why this method keeps showing up on factory floors. 🔧 What Makes Saw Blade Depaneling So Widely Used? In mass production, consistency matters more than anything. Saw blade depaneling delivers exactly that. It uses a rotating blade to separate PCBs along straight lines, typically V-grooves. The process is simple, repeatable, and fast. No complex programming.No expensive setup.Just stable throughput. For manufacturers producing thousands—or millions—of identical boards, that reliability becomes a major advantage. ⚙️ Speed vs. Precision — Where It Fits Best Not every depaneling
Why PCB Router Depaneling Is Widely Used in Electronics Manufacturing
PCB router depaneling remains one of the most common PCB separation methods in electronics manufacturing. Even with newer technologies like laser cutting, many factories still rely heavily on router systems for daily production. Why? Because router depaneling sits in a practical middle ground. It offers flexibility, stable cutting quality, and reasonable operating cost. For many PCB designs, that balance makes it the most reliable choice. In real manufacturing environments, the decision is rarely about technology alone. Engineers care about yield stability, production speed, board design, and long-term reliability. 🔍 Router Depaneling Handles Complex PCB Shapes One of the biggest advantages of router depaneling is its cutting flexibility. Unlike V-cut separation, which only works along straight panel lines, router systems follow
How Do Engineers Decide If PCB Router Depaneling Is Necessary?
PCB router depaneling is one of the most widely used PCB separation methods in electronics manufacturing. But engineers rarely choose it automatically. In many projects, the decision is made only after reviewing PCB design details, production requirements, and reliability risks. Some boards work perfectly with V-cut separation. Others require laser cutting. In many cases, router depaneling is the most balanced option. So how do engineers actually make that decision in real production environments? 🔍 The First Question Engineers Ask — How Is the PCB Designed? The PCB layout usually determines the depaneling method. Engineers start by checking several key design factors: If the board outline includes curves, internal slots, or complex contours, router depaneling is often necessary because routers can follow
