The SPEA 4040, claimed to be the fastest and most precise flying prober, contacts now on both board sides. The bottom-side moving heads test the underside and thus enable a synchronous access to the top and bottom side of an assembly. The movable heads are freely movable, programmable and cover a size of up to 600x500mm. The XY-axes are driven by linear motors with closed-loop circuit. However, the moving heads are not simple probes for verifying undersides, but rather a multifunction tool performing demanding tasks. Depending on the requirement, they can carry out a range of verification procedures such as: standard tests, electro-scan, on-board programming, boundary scan, power-on and functional tests as well as optical inspection. In addition, equipped with a marking unit they can write on board assemblies. If the underside of an assembly needs not be contacted, the heads can rather be used to support bigger boards from below. The operating software automatically takes into account the profile of an assembly, so that higher components on a board will not represent any problem. The marking as “no-fly-zone“ assures a safe crossing or driving around the parts. Contacting on both sides extends the application area of this test equipment, so reportedly it is labeled the most modern flying prober on the market.
