1. The interference suppression and noise feedback control thresholds can be determined by R13 or a capacitive voltage divider at the input of the high-pass filter and they are defined by the following formulae: Vi(tr) = (1 + R13/RS) × Vi(tr)O in which RS = 2 k; Vni = (1 + R13/RS) × VniO in which RS = 2 k. 2. The suppression pulse duration is determined by C11 = 2,2 nF and R11 = 6,8 k. 3. The characteristic of the noise feedback control is determined by R12 (and R10). 4. The feedback control of the interference suppression threshold at higher repetition frequencies is determined by R10 (and R12). 5. The 19 kHz generator can be adjusted with R7-16 (and R7-8). Adjustment is not required if components with small tolerances are used e.g. R < 1% and C < 2%. 6. Measuring conditions: The peak output noise voltage (Vno m, CCITT filter) shall be measured at the output with a de-emphazing time T = 50 µs (R = 5 k, C = 10 nF); the reference value of 0 dB is Vo int with the 19 kHz generator short-circuited (pin 7 grounded).

Interference and noise suppression circuit for FM receivers
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. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). DIP SOLDERING BY DIPPING OR BY WAVE The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. REPAIRING SOLDERED JOINTS Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 °C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 °C, contact may be up to 5 seconds. SO REFLOW SOLDERING Reflow soldering techniques are suitable for all SO packages. Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement.
TDA1001B TDA1001BT
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.
