Publication number: 20020182500Abstract: A lead alloy for lead acid-battery grids which essentially consists of about 0.05-0.07 wt % calcium; about 0.09-1.3 wt % tin; about 0.006-0.010 % silver; about 0.0100-0.0170 wt % barium and about 0.015-0.025 wt % aluminum with the balance lead. This lead alloy allows the improvement of the age hardening step, by eliminating the high temperature treatment process required for silver alloys in the manufacturing of lead-acid batteries. By using this lead alloy, a longer service life of the lead-acid batteries are also obtained by increasing the corrosion resistance and the mechanical strength of battery grids manufactured by the book molding process. Additionally, the reduced silver level used dramatically mitigates the problem of silver elimination from the stream of recycled lead in the secondary production of this metal.Type: ApplicationFiled: June 4, 2001Publication date: December 5, 2002Applicant: ENERTEC MEXICO, S. de R.L. de C.V.Inventors: Luis Francisco Vazquez Del Mercado, Luis David Silva-Galvan

Patent number: 6016947Abstract: A non-destructive method for identifying off-composition solder columns of for example, a ceramic column grid array. The method is performed at the ceramic module level prior to card assembly to avoid costly loss or rework post card assembly. The assembly of solder columns on a substrate is heated to a temperature below the melting temperature of pure-composition solder and above the temperature of attachment of a solder column to an organic board. Heating the assembly produces visually detectable changes characteristic of off-composition solder which are used for identifying which solder columns are composed of off-composition solder.Type: GrantFiled: October 21, 1997Date of Patent: January 25, 2000Assignee: International Business Machines CorporationInventors: Timothy W.

Patent number: 4525327Abstract: A lead based alloy for electrode supports of a lead-acid storage cell, the alloy containing between 0.05% and 4% antimony between 0.02% and 0.3% magnesium, and no barium.
