For High Cut Control (HCC), the de-emphasis time constant can be changed to higher values (see Figs 7 and 8). This function is controlled by an analog input signal. The noise blanking facility is achieved by gating the stereo decoder output signal. The interference detector generates a gating pulse preferable forced by the level detector voltage of the IF part.

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. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. WAVE SOLDERING Wave soldering techniques can be used for all SO packages if the following conditions are observed: A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. The longitudinal axis of the package footprint must be parallel to the solder flow. The package footprint must incorporate solder thieves at the downstream end. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 C within 6 seconds. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. REPAIRING SOLDERED JOINTS Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C.
