Don't try to pull the component away from the carrier otherwise you could damage it. NOTE: Some components have pre-bent leads and they'll need to be reformed to allow the part to fully seat on the surface of the circuit board. NOTE: Polarized capacitor locations include a "+" (plus sign) silkscreened where the positive lead orients.
