11, Philips TDA4861 1997 Jan 20 11 Philips Semiconductors Product specification Vertical deflection power amplifier for monitors TDA4861 SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with hi…
