A manufacturer of automated equipment for low-cost testing of complex printed circuit board assemblies has specified two Spyraflo bearings for its analysing machine.
The machine applies multiple test-probe points across a PCB to locate any manufacturing defects such as incorrect, missing or mis-oriented components and electrical-current opens or shorts.The machine's multiple spring-loaded probes are mounted in a custom platen, which is accurately positioned by a scissors mechanism to ensure that its hundreds of test points are heavily loaded on the appropriate areas of the PCB.
The complete scissors mechanism is held in place by four PB2-750P 19mm-diameter Teflon-Bronze, Aluminium Pillow-Block Bearings.
In addition, four FSP375N Self-Clinching 9.5mm-diameter Teflon-Bronze Bearings are securely mounted into the arms of the assembly carrying the extreme load associated with the elbows of the scissors mechanism.
The self-clinching process eliminates risk to the bearing's ID during installation and ensures a secure, permanent fit that won't come lose during operation.
