The Pad ROL200 contact uses a rolling, elastomeric biasing contact design that works as a self-cleaning wipe to decrease cleaning cycle frequency, preserve load boards, and maintain electrical performance. The tip design reduces tin oxide build-up, which the company claims will extend mean time between assists (MTBA). The contacts are housed in the corresponding contactors and suit testing for lead-less, pad-style applications such as quad flat no-lead (QFN) and dual flat no-lead (DFN) packages.
