10. MountingRecommendations˃ Provideproperlyspacedholesformountingaccordingtothespecifiedcelldimension
inordertominimizetheterminalsofthecellbeingmechanicallystressed.˃ Donotplaceanythrough-holesdirectlyunderneaththecellorinthecloseproximity
ofthecell.Allowatleast5mmdistancefromanypointontheouterdiameterofthecelltotheouterdiameterofanythrough-hole.
˃ Protective coating of components on the PCB is strongly recommended in order toreducetheriskofthecomponentsbeingdamagedinaneventofelectrolyteleakage.
˃ Provide at least 2mm clearance from the safety vent and do not position anythingnearthesafetyventthatmaybedamagedbytheventrupture.
˃ AssemblethecellonthePCBtakingintoaccountthatthecellmaynotbecompletelyhermetic during its lifetime. Electrolyte vapor and gases generated during normaloperationmayescapethepackage.
