Equivalent Circuit. 1 2 Figure 13. Internal Connections. Co-Planar Waveguide Shunt Connection for HSMP-482x Series Co-Planar waveguide, with ground on the top side of the printed circuit board, is shown in Figure 17. Since it eliminates the need for via holes to ground, it offers lower shunt parasitic inductance and higher maximum attenuation when compared to a microstrip circuit. See AN1050 for details. Figure 14. Circuit Layout. Co-Planar Waveguide Groundplane Microstrip Shunt Connections for HSMP-482x Series In Figure 15, the center conductor of the microstrip line is interrupted and leads 1 and 2 of the HSMP-482x diode are placed across the resulting gap. This forces the 0.5 nH lead inductance of leads 1 and 2 to appear as part of a low pass filter, reducing the shunt parasitic inductance and increasing the maximum available attenuation. The 0.3 nH of shunt inductance external to the diode is created by the via holes, and is a good estimate for 0.032" thick material. Center Conductor Groundplane Figure 17.

Components with a low mass, such as the SOT-323/-23 package, will reach solder reflow temperatures faster than those with a greater mass. The preheat zones increase the temperature of the board and components to prevent thermal shock and begin evaporating solvents from the solder paste. The reflow zone briefly elevates the temperature sufficiently to produce a reflow of the solder. The rates of change of temperature for the ramp-up and cool-down zones are chosen to be low enough to not cause deformation of the board or damage to components due to thermal shock. The maximum temperature in the reflow zone (TMAX) should not exceed 260°C. Avago’s diodes have been qualified to the timetemperature profile shown in Figure 21. This profile is representative of an IR reflow type of surface mount assembly process. These parameters are typical for a surface mount assembly process for Avago diodes. As a general guideline, the circuit board and components should be exposed only to the minimum temperatures and times necessary to achieve a uniform reflow of solder. After ramping up from room temperature, the circuit board with components attached to it (held in place with solder paste) passes through one or more preheat zones. tp Tp Critical Zone T L to Tp Ramp-up Temperature TL Ts Ts tL max min Ramp-down ts Preheat 25 t 25° C to Peak Time Figure 21.
