Manual Solutions

Curve Tracing has its roots in Manual test methods like Pin to Pin curve tracing.  As the technique has evolved, so have the hardware solutions.  While some information can be gleaned from poking at the part with probes, it quickly becomes evident that more formal and efficient methods are needed to hold the device and provide reliable means to electrically connect to the pins.

Manual curve tracing is sometimes called a “Bench Test”.

RTI Supports Manual Curve traces methods with Manual Switch Boxes, Test Cables, Test Fixtures, DUT Boards and Breakout Boards:
  • Fixtures and Interfaces:  RTI has a variety of test fixtures well suited for manual or automated curve tracing.  96, 128 and 384 pin pogo block fixtures with compatible Yamaichi cables are an excellent interface choice.
  • Dedicated DUT Boards:  DUT Boards made for one particular device or featuring an RTI Universal BGA or Universal CSP socket can be directly connected to the switch box without an intervening fixture. 
  • Interchangeable DUT boards:  DUT boards made to be swapped onto a fixture are a common choice.  The fixture base can provide a convenient stand or in microscope mounting point while keeping the DUT board small and simple.  Features like a breakout area can often be added to the DUT board making it even more convenient for Bench Test menthos
  • Manual Switch Boxes:  96 pin Toggle Switch boxes simplify a variety of bias conditions and are compatible with dedicated fixtures, Spring pin interfaces like RTIs 950 fixture, as well as DUT boards made by some 3rd party suppliers. 
  • Breakout Boards:  These are fixtures that feature some kind of array of test points often used for bench testing.  The test points can be 1 2 or 3 pin and can be simple header pins, banana jacks or another kind of connector.
    • Single pin breakout is called a “Test Point” and just goes from the device pin to the test point.
    • 2 pin jumpers are usually installed in series with the DUT pin and are called “make Break” jumpers because they can open or close a circuit like a switch
    • 3 pin jumpers are used for programming pins to one of two bias nodes.  The center pin goes to the DUT pin and the outer two pins go to power planes these are called “Programming” Jumpers
