Samtec Bulls Eye® test point systems are ideal for high-performance test applications because of their compression interfaces, small footprint, and high cycle count capabilities. Bulls Eye is now available in 50 GHz and 20 GHz designs, with a system up to 70 GHz in development.
Bulls Eye is a popular product because:

- The grid design and smaller footprint enables smaller evaluation boards and shorter trace lengths. The high-density array design significantly saves PCB space compared to traditional test points.
- The compression interface to the board provides easy on/off and eliminates soldering costs.
- The contacts are designed for high cycle counts, and replacement components are easy to order.
Here’s an article from our friends at Electronic Products about the collaboration between Samtec, eSilicon, and Wild River Technology to test a 56-/112-Gbps PAM4 SerDes for use in IEEE 802.3bs (200-/400-Gbps Ethernet).
And here’s another article from our friends at Signal Integrity Journal discussing how this test system addresses the demands of 56/112G PAM4 using the upcoming IEEE P370 standard.
And we have more friends at Xilinx who incorporate Bulls Eye into their characterization kits, like the Zynq UltraScale+ RFSoC ZCU1275 and the Virtex UltraScale VCU1287, to name a few. (In Indiana we try to be friendly.)
Our new BE40A series is a 50 GHz, double row system with signal and ground pogo pins. End 2 connectors are 2.92 mm and 2.40 mm, it’s available in microstrip or stripline PCB transmission, and is backward compatible with legacy, double row BDRA series 20 GHz solutions (stripline only).
The 70 GHz, BE70A series, currently in development, is a dual row system available in stripline or microstrip PCB transmission with a 1.85 mm End 2 connector.
