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 Equipment: Router vs Laser vs V-Cut vs Saw Blade — What Works Best?
PCB Depaneling Equipment has evolved quickly over the past decade as electronics manufacturers push for higher-density boards, tighter tolerances, and more diverse materials. Across Europe, North America, and Asia, factories have adopted different depaneling technologies based on volume demands, quality requirements, component sensitivity, and long-term equipment cost.This article shares real shop-floor observations, user pain points, cost considerations, and practical case insights to help engineers compare the four major methods: Router, Laser, V-Cut, and Saw Blade. 🔧 Router Depaneling — Flexible and Precise for Complex Designs Router systems remain popular in automotive, industrial control, and IoT PCB assembly lines.What technicians appreciate: Challenges reported from European SMT lines: Best fit: Medium-to-high-precision PCBs with heavier components or complex outlines. 🔥 Laser Depaneling —
PCB Milling Cutter Machine vs V-Cut Method: What Global SMT Lines Prefer
PCB Milling Cutter Machine technology has increasingly replaced traditional V-cut separation in global SMT factories, especially as PCBs become thinner, denser, and more mechanically sensitive. While the V-cut method remains widely used in cost-driven or legacy production lines, manufacturing teams in Europe, North America, and Southeast Asia are reconsidering which depaneling approach brings better stability, reliability, and long-term yield. Below is a practical comparison based on insights shared by engineers, maintenance technicians, and line supervisors from Germany, France, the United States, and key Asian manufacturing hubs. 🏭 H1 — Why Factories Reevaluate PCB Separation Methods The core issue for modern SMT lines is mechanical stress. V-cut’s simplicity is appealing, but it introduces bending forces that many OEMs now consider unacceptable.
Automatic PCB Bottom Router Machine: How to Ensure That Components Are Not Damaged During PCB Cutting?
Automatic PCB Bottom Router Machine technology has become a core process in PCB depaneling for factories dealing with dense component layouts, fragile materials, and increasingly complex structures. A recurring question among European production engineers is straightforward but critical: How can we guarantee that components are not damaged during high-speed routing? Across different SMT lines in Germany and France, technicians share similar pain points — vibration affecting tall components, micro-cracks forming under thermal or mechanical stress, and unpredictable panel movement during cutting. Below is a collection of field-tested insights from daily production. 🔧 H1 — The Real Challenges Behind Component Safety in Bottom Routing Damage rarely occurs “suddenly.” Instead, it results from small, accumulated mechanical forces. The most common factors include:
Fixtureless PCB Depaneling Machine: Handling Warping, Thin Panels, and Complex Shapes
Fixtureless PCB Depaneling Machine solutions have become essential in modern SMT lines where board materials, component density, and outline geometry are more challenging than ever. Many production teams in Europe and North America continue to share similar questions: How do you keep panel stability under control? How do you avoid micro-cracks, edge stress, and material distortion when the PCB structure itself is fragile?Below are field-tested insights gathered from different factories running daily high-precision operations. 🔧 H1 — The Real Pain Points Behind Warping and Thin PCB Panels Warping is not only a material issue; it often increases when the panel size becomes larger or when the copper distribution is uneven. In Germany and France, engineers frequently point out three recurring
