Philips Semiconductors Product specification 1 W BTL mono audio amplifier with DC volume control TDA7052A/AT THERMAL RESISTANCE SYMBOL Rth j-a PARAMETER THERMAL RESISTANCE from junction to ambient in free air TDA7052A 100 K/W TDA7052AT 155 K/W Notes to the thermal resistance TDA7052A: VP = 6 V; RL = 8 Ω. The maximum sine-wave dissipation is 0.9 W. Therefore Tamb(max) = 150 − 100 × 0.9 = 60 °C. TDA7052AT: VP = 6 V; RL = 16 Ω. The maximum sine-wave dissipation is 0.46 W.

Philips Semiconductors Product specification 1 W BTL mono audio amplifier with DC volume control Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 °C. SOLDERING Introduction There is no soldering method that is ideal for all IC packages.
