Power-One will nothonor any warranty claims arising from failure toobserve these instructions.The lead-frame is constructed for a hightemperature glass filled, UL94 V-0 flame retardant,dually ortho-phthalate molding compound commonlyused for packaging of electronics components. Ithas passed NASA outgassing tests, and is certifiedto MIL-M-14. The coefficient of thermal expansion isequivalent to FR4.The gull wing leads are formed to ensure optimalsolder joint strength and structure. Furthermore theyfacilitate visual inspection (manual or automatic).The leads are formed from a 97% Cu alloy platedwith Ni and matte Sn. This material is commonlyusedin the manufacture of integrated circuits. It has goodcorrosion resistance and exhibits the nobilityinherent to all high copper alloys. Unlike brasses,this material is essentially immune to stresscorrosion cracking. It also exhibits excellentsolderability. It is readily wetted by solders andperforms well in standard solderability tests. (Dip ofClass II or better).The product is manufactured with a patentedprocess, which is fully automated, and ‘in-line’. Thisensures that there is no contamination ormechanical stress on the lead-frame so that the coplanarity and solderability are maintained.The product is shipped in JEDEC trays to ensurepreservation of the co-planarity and enable fullyautomated assembly in the final application. Mindthe marking for pin 1!These products are approved for forced convectionreflow soldering only. Products RoHS-compliant forall 6 substances (model designation ending with -M6G) allow for a solder profile with highertemperatures; see following tables.BCD.00038 Rev.
