Philips Semiconductors Product specification 2 W BTL audio amplifier TDA8543 SOLDERING to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Introduction Several techniques exist for reflowing; for example, There is no soldering method that is ideal for all IC thermal conduction by heated belt. Dwell times vary packages. Wave soldering is often preferred when between 50 and 300 seconds depending on heating through-hole and surface mou
