Recommended Reflow Profile
The reflow profile is a straight-line representation of a
nominal temperature profile for a convective reflow sol-
der process. The temperature profile is divided into four
process zones, each with different ∆T/∆time temperature
change rates or duration. The ∆T/∆time rates or duration
are detailed in the above table. The temperatures are
measured at the component to printed circuit board
connections.
In process zone P1, the PC board and HSDL-3000 pins are
heated to a temperature of 150°C to activate the flux in
the solder paste. The temperature ramp up rate, R1, is
limited to 3°C per second to allow for even heating of
both the PC board and HSDL-3000 pins.
Process zone P2 should be of sufficient time duration (100
to 180 seconds) to dry the solder paste. The temperature
is raised to a level just below the liquidus point of the
solder, usually 200°C (392°F).
Process zone P3 is the solder reflow zone. In zone P3, the
temperature is quickly raised above the liquidus point
of solder to 255°C (491°F) for optimum results. The

dwell time above the liquidus point of solder should
be between 20 and 40 seconds. It usually takes about
20 seconds to assure proper coalescing of the solder
balls into liquid solder and the formation of good solder
connections. Beyond a dwell time of 40 seconds, the
intermetallic growth within the solder connections be-
comes excessive, resulting in the formation of weak and
unreliable connections. The temperature is then rapidly
reduced to a point below the solidus temperature of the
solder, usually 200°C (392°F), to allow the solder within
the connections to freeze solid.
Process zone P4 is the cool down after solder freeze. The
cool down rate, R5, from the liquidus point of the solder
to 25°C (77°F) should not exceed 6°C per second maxi-
mum. This limitation is necessary to allow the PC board
and HSDL-3000 pins to change dimensions evenly, put-
ting minimal stresses on the HSDL-3000.
It is recommended to perform reflow soldering no more
than twice.
