KEMET's recommendedprofileconditionsforconvectionandIR reflowreflecttheprofileconditionsoftheIPC/J–STD–020D standard for moisture sensitivity testing. The devices can safelywithstandamaximumofthreereflowpassesatthese conditions. PleasenotethatalthoughtheX/7343–43casesizecan withstandwavesoldering,thetallprofile(4.3mmmaximum) dictates care in wave process development. Hand soldering should be performed with care due to the difficultyinprocesscontrol.Ifperformed,careshouldbe taken to avoid contact of the soldering iron to the molded case. The iron should be used to heat the solder pad, applying solderbetweenthepadandthetermination,untilreflow occurs.Oncereflowoccurs,theironshouldberemoved immediately. “Wiping” the edges of a chip and heating the top surface is not recommended. Duringtypicalreflowoperations,aslightdarkeningofthe gold-colored epoxy may be observed. This slight darkening is normal and not harmful to the product. Marking permanency is not affected by this change.

While the chips themselves are quite robust in other environments, solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and long term storage. In addition, packaging materials will be degraded by high temperature – reels may soften or warp and tape peel force may increase. KEMET recommends that maximum storage temperature not exceed 40°C and maximum storagehumiditynotexceed60%relativehumidity.Temperaturefluctuationsshouldbeminimizedtoavoidcondensationon thepartsandatmospheresshouldbefreeofchlorineandsulphurbearingcompounds.Foroptimizedsolderabilitychipstock should be used promptly, preferably within three years of receipt.
