Selecting Your Probe Type

• Choose the series for your application according to its properties, and then select the correct combination of test point size and travel/stroke length.
• Choose the most suitable tip style. This chart should answer most queries. Factors affecting your choice include the cleanliness of the PCBs, the component's leg length and whether or not the legs are clinched
• Choose the correct spring rate. A heavier spring will give a better penetration of dirt or flux but the total number of points on the fixture must also be considered. There are various pressures dependant upon the probe. These are given in the appropriate section for each probe type.
