How Accurate Is PCB Saw Depaneling?

This is one of the first questions engineers ask when evaluating depaneling methods for volume production. Saw blade depaneling is widely used in SMT lines, especially for standard FR4 panels—but accuracy is often misunderstood. The short answer: PCB saw depaneling is accurate enough for many mass-production boards, but it has clear limits. Understanding those limits […]

Does Laser PCB Depaneling Meet Mass Production Demands?

This question comes up frequently as electronics move toward higher density, thinner materials, and stricter reliability requirements. Laser depaneling is often associated with precision and flexibility—but can it really keep up with volume manufacturing? The short answer: yes, but only under the right conditions. This article looks at where laser depaneling works well in mass […]

New Year, Full Speed: Seprays Is Back in Action

Glorious Resumption of Work · Embarking on a New Journey On the twelfth day of the first lunar month, February 28, 2026, Seprays Group officially resumed operations, marking the start of a new chapter in the year ahead. As we move into the new year, we remain committed to creating long-term value for our global […]

Does Saw Blade Depaneling Damage Components?

This is one of the most common questions engineers ask when evaluating depaneling methods for high-volume SMT production. The short answer is: it depends on how the process is designed, not just the cutting method itself. Saw blade depaneling can be fast and consistent, but it also introduces mechanical forces that must be controlled carefully. […]

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 […]

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, […]

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 […]

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 […]
