XJTAG launched a newest powerhouse for PCB testing for high-density circuit board diagnostics
XJTAG, Cambridge, England is a leader in electronic testing solutions which has showcased its latest innovation, the ‘XJLink-PF40 JTAG’ controller, at Electronica 2024, Munich. This newly introduced joint test action group (JTAG) controller is set for release in 2025 and is designed to meet the intricate demands of printed circuit board (PCB) prototyping and manufacturing which will be offering PCB engineers a durable tool for tackling complex and high-density circuit boards.
Engineers in R&D, production line testing, and those focused on board bring-up and debugging will find this controller invaluable in increasing test coverage and reliability across multiple access points on a unit under test (UUT). With its configuration of up to eight JTAG TAPs and 40 I/O pins, it expands test coverage for demanding applications, enabling engineers to enhance accuracy and diagnostics even on intricate board designs. “The XJLink-PF40 is ideal for engineers tackling high-density projects who need flexible, reliable testing solutions,” notes the company, emphasising its utility in complex test environments.
Adding to its adaptability, the controller offers multi-voltage domain capabilities, with four voltage domains allowing connectors to operate independently for versatile testing conditions. Each TAP can operate at configurable frequencies, ensuring compatibility with specific circuit needs a critical feature for those involved in diverse testing scenarios.
Another innovation lies in the connector design, with 20-way connectors featuring even-numbered pins as ground (GND) for improved signal integrity, while odd-numbered pins are configurable as I/O or TAP pins. Housed in a durable aluminium case, the controller withstands voltages of ±30V on any pin, meeting the robustness requirements of high-demand production environments.
Widely used across various industries, the company’s tools aid engineers in board bring-up, testing, and debugging, driving efficiency and reliability in electronic production. You may click here for more information.
