WebQuantiServ has built up a lot of experience in white metal bearing reconditioning. Depending on the bearing’s application, we apply either a static or a centrifugal casting process and then carry out all post-casting machining work in-house. We exclusively use tin-based white metal and no lead-based one because the former has a much greater ... WebTable 1 compares a standard lead-free sphere to a standard lead-bearing sphere. As shown in Table 1, lead-free sphere BGA packages require a higher reflow temperature during soldering than lead-bearing sphere BGA packages, typically 20–40°C hotter. Parts with a moisture sensitivity level (MSL) 3 require a peak reflow of 245–260°C.
