Mixed signal test platforms require the load board to be changed nearly as often as the probe card. The Xandex PCLBA design (Probe Card, Load Board/Interface Assembly) incorporates the existing load board and stiffener, the interface tower, and the probe card and stiffener into one compact assembly, which attaches directly to the tester.
This tightly integrated package ensures proper alignment of Pogo pins to both the load board and the probe card, ensuring accurate signal transmission. Touch Memory modules mounted on the Probe Card and on the Load Board allow for dynamic storage and retrieval of data about these components and their usage. This solution provides cost-effective time savings because there is no requirement to purchase new cards or associated hardware. Features and BenefitsNo need to undock test head to swap out probe card and/or load boardTightly integrated package ensures proper alignment of Pogo pins to both the load board and the probe card, thus ensuring accurate signal transmissionDoes not require dedicated manipulator at work cell - reduces floor space requirementsNo prober "head plate" or "ring carrier" required - allows for reduced length of signal path between pin electronics and DUTMechanically robustPTI is an easily separable part of the PCLBA - easy to maintain; individual spring contact pin tips are easily replaced if damagedLowered maintenance costs resulting from less docking/undocking and less operator handling of delicate interface components |
