Sigma Series WLCSP Probe Head



             Highly parallel, stable test performance for full function wafer testing



              WiFi 6+                        5G                       IoT               Automotive




         TTS Sigma Series WLCSP Probe Heads are designed to provide optimal performance and signal integrity
         for full functional test of high frequency devices in both the HVM wafer testing environment and during lab
         qualification. With long pin life, low inductance, and repeatable and stable contact resistance, Sigma Series
         Probe Heads can increase first pass yields, reduce maintenance down time, and improve overall cost of test.
         TTS uses our internally developed, custom made pins, advanced engineering materials and extensive
         simulations to ensure we deliver a product that is capable of high parallelism, tri-temp testing, and works out
         of the box each and every time. With pitch capabilities down to 150um, TTS WLCSP products can meet and
         exceed all your WLCSP testing needs.
