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 component pins are heated to a temperature of 150C to activate the flux in the solder paste. The temperature ramp up rate, R1, is limited to 3C per second to allow for even heating of both the PC board and component 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. Process zone P3 is the solder reflow zone. In zone P3, the tem- For product information and a complete list of distributors, please go to our web site: perature is quickly raised above the liquidus point of solder to 260C (500F) for optimum results. The dwell time above the liquidus point of solder should be between 60 and 90 seconds. This is to assure proper coalescing of the solder paste into liquid solder and the formation of good solder connections. Beyond the recommended dwell time the intermetallic growth within the solder connections becomes 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 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 25C (77F) should not exceed 6C per second maximum. This limitation is necessary to allow the PC board and component pins to change dimensions evenly, putting minimal stresses on the component. It is recommended to perform reflow soldering no more than twice. www.avagotech.com Avago, Avago Technologies, and the A logo are trademarks of Avago Technologies in the United States and other countries.
