In electronics manufacturing, downtime is rarely caused by machines failing outright. More often, it comes from small interruptions in material flow. In through-hole assembly and radial component insertion, one of the most common and frustrating problems is damaged or depleted carrier tape. When a tape breaks or runs out at the wrong moment, even the most advanced auto-insertion machine comes to a stop.
That is where SMT Radial Axial tape splice products play a critical role. These splices allow operators to reconnect carrier tapes quickly and accurately so production can continue without misfeeds, jams, or alignment errors. Sierra Electronics has been manufacturing these solutions for decades, and their radial splice tapes are designed by people who understand real-world production demands.
Having used these products on active lines, the difference in reliability and consistency is immediately noticeable.
Radial components are typically supplied on carrier tapes that feed directly into auto insertion equipment. These machines rely on alignment holes in the tape to position components correctly before insertion. If the tape is damaged, misaligned, or ends abruptly, the entire line can stop.
Tape splices solve this problem by joining two sections of carrier tape together with precise hole alignment and a high-strength adhesive. A proper splice maintains correct pitch, keeps the tape rigid, and ensures smooth feeding through the machine.
Sierra’s SMT Radial Axial splice tapes are designed to meet those requirements without adding complexity to the process. They are easy to apply, hold firmly under tension, and maintain consistent alignment throughout long production runs.
One of the reasons these splice tapes stand out is how they are made. Sierra Electronics manufactures all of its splice products in the United States, maintaining strict quality control from raw materials through final packaging.
This matters on the factory floor. Consistent adhesive strength, uniform hole placement, and reliable material thickness all translate into predictable machine behavior. When you use the same splice hundreds of times per shift, that consistency prevents small issues from turning into costly downtime.
There is also confidence in knowing that these products are tested in real production environments, not just in controlled lab settings.
Sierra offers three distinct radial splice formats, each designed to meet different production needs while maintaining the same core quality.
2-Hole Tape Splice for Radial Components
The 2-hole splice is the most straightforward option and is commonly used in standard radial insertion setups.
It features two precisely punched alignment holes that match common carrier tape formats. The adhesive bonds securely without curling or lifting, even when the tape is under constant motion.
In day-to-day use, the 2-hole splice is ideal for fast repairs and routine reel changes. It is simple, reliable, and easy to apply without tools. For many production lines, this splice handles the majority of splicing needs without issue.

The 3-hole splice adds an extra alignment point, which improves tape stability and feeding accuracy.
That third hole provides better pitch control and reduces lateral movement, especially on faster machines or longer runs. This added precision can significantly reduce misfeeds and sensor errors.
From experience, switching to 3-hole splices on high-speed lines results in smoother operation and fewer interruptions. It is a solid upgrade for facilities that demand tighter control without slowing down production.
The 5-hole splice is the most robust option in the lineup and is designed for maximum alignment and stability.
With five alignment holes, the tape is locked into position as it passes through the feeder. This configuration minimizes drift and maintains consistent positioning even under high tension or continuous operation.
This splice is often chosen for demanding environments such as automotive electronics, medical devices, aerospace assemblies, and other high-reliability applications. When uptime and precision are critical, the 5-hole splice delivers confidence.
These SMT Radial Axial splice products are widely used across industries that still depend on through-hole or mixed-technology assembly, including:
In each of these industries, unplanned downtime can be costly, and reliable splicing is a small investment that protects production flow.
Using high-quality radial splice tapes delivers several practical advantages:
Because each roll contains 1000 splices, operators can work through full shifts without worrying about running out of splicing material at critical moments.
SMT Radial Axial tape splices may seem like a small accessory, but in real production environments, they are essential. Sierra Electronics’ 2-hole, 3-hole, and 5-hole splice tapes are built for the realities of modern manufacturing: speed, precision, and reliability.
After using them on active lines, the value is clear. They install quickly, feed smoothly, and hold up under continuous operation. Combined with consistent Made in USA quality, these splice tapes are a dependable solution for keeping through-hole assembly lines running efficiently.
When every minute of uptime matters, choosing the right splice tape is not optional, it is part of running a disciplined, professional production operation.
