Unleashing Precision with Boundary Scan Technology: E-Metric Technology Elevates Automated Test Equipment


In the rapidly evolving landscape of electronics manufacturing, ensuring the integrity and performance of complex products is more critical than ever.

As electronics become increasingly intricate, densely packed, and with higher speed signals, traditional testing methods can struggle to keep pace. This is where boundary scan technology comes into play.

E-Metric Technology specializes in the design and development of cutting-edge Automated Test Equipment (ATE) that leverages boundary scan to deliver unparalleled testing precision and efficiency.

What Is Boundary Scan Technology?

Boundary scan, also known as JTAG (Joint Test Action Group), is a powerful method for testing and debugging integrated circuits (ICs) and printed circuit boards (PCBs). Introduced since the 1980s, boundary scan has been providing a standardized approach to testing and verifying the electrical connections and functionality using built-in test logic.

The method of boundary scan involves integrating a Boundary Scan Cell into each IC, which enables testing the I/O pins and interconnections through a standardized test interface.

The core of boundary scan lies in its ability to test without physical access to the internal signals of the circuits. It utilizes a serial test access port (TAP) to communicate with boundary scan cells and perform various operations:

  • Boundary Scan Testing: Verifying connections between ICs and detecting faults like open / short circuits.
  • In-System Programming: Programming and debugging ICs while they are in operating environment.
  • Debugging and Diagnostics: Identifying issues within the circuitry and debugging complex systems with high-speed data paths.
