The Spring Contact Test Probes Tip Selection Page


Most tip styles can be used in a variety of applications. Factors to consider for loaded board tip selection are lead length (bent or straight), cleanliness and pad size. In general, tips with sharp points and internal cutting edges (to trap the lead) such as the Crown or Tulip, are excellent choices. To penetrate through contamination on bare boards choose a tip with sharp external cutting edges, like the Chisel or Star tip. These tips may mark the contact surface. As an alternative, use the Convex tip on boards which are clean and free of contaminants. Experiment with several different styles until you find the one that works for your application.
