    ... Philips Semiconductors Data amplifier and laser supply circuit for CD audio and video optical systems (ADALASLC) 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 high population densities ...
