INTEGRATED CIRCUITS DATA SHEET TDA6800 TDA6800T Video modulator circuit Product specification File under Integrated Circuits, IC02 March 1986 Philips Semiconductors Product specification TDA6800 TDA6800T Video modulator circuit GENERAL DESCRIPTION The TDA6800 is a modulator circuit for modulation of video signals on a VHF/UHF carrier. The circuit requires a 5 V power supply and few external components for the negative modulation mode. For positive modulation an external clamp circuit is required. This circuit can be used as a general purpose modulator without additional external components.

Typical reflow temperatures range from 215 to 250 °C. SOLDERING Introduction Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 °C. 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. WAVE SOLDERING Wave soldering techniques can be used for all SO packages if the following conditions are observed: 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). • A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. DIP • 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. 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. 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. 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. 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 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. 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. 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. Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating March 1986 9 Philips Semiconductors Product specification TDA6800 TDA6800T Video modulator circuit DEFINITIONS Data sheet status Objective specification This data sheet contains target or goal specifications for product development.
