Maximum Ramp Up Rate = 3ºC/seconds

Maximum Ramp Down Rate = 6ºC/seconds

Soldering Process

KEMET’s families of surface mount capacitors are compatible

withwave(singleordual),convection,IR,orvaporphasereflow

techniques. Preheating of these components is recommended

toavoidextremethermalstress.KEMET'srecommended

profileconditionsforconvectionandIRreflowreflecttheprofile

conditions of the IPC/J–STD–020D standard for moisture

sensitivity testing. The devices can safely withstand a maximum

ofthreereflowpassesattheseconditions.

Please note that although the X/7343–43 case size can withstand

wavesoldering,thetallprofile(4.3mmmaximum)dictatescarein

wave process development.

Handsolderingshouldbeperformedwithcareduetothedifficulty

in process control. If performed, care should be taken to avoid

contact of the soldering iron to the molded case. The iron should

be used to heat the solder pad, applying solder between the pad

andthetermination,untilreflowoccurs.Oncereflowoccurs,the

ironshouldberemovedimmediately.“Wiping”theedgesofachip

and heating the top surface is not recommended.

Duringtypicalreflowoperations,aslightdarkeningofthegold-

colored epoxy may be observed. This slight darkening is normal

and not harmful to the product. Marking permanency is not

affected by this change.
