However, the implementation of the RTS profile can reduce energy costs, increase efficiency, reduce solder defects, improve wetting and simplify the reflow process. Table 2 lists the reflow profile recommendations. Table 3 lists the Sn-Pb eutectic process peak reflow temperature (T P). Table 4 lists the Pb-free process peak reflow temperature (T P). Table 2. Reflow Profile Recommendations (JEDEC/IPC J-STD-020D.1) (1) Profile Feature Sn-Pb Eutectic Assembly Pb-Free Assembly Average ramp-up rate (Ts MAX to T P) The 'Reflow Profile' calculator is now available in our Calculators section.

Reflow profile

The two most common types of reflow profiles are the ramp-to-peak profile, also called ramp-to-spike or tent profile (see Figure 1) and the soak profile, or ramp/soak/spike profile (see Figure 2). A ramp-to-peak profile is a linear ramp to the peak (max) temperature. A soak profile displays some “plateau” within a limited the reflow profile allows the thermal gradient across the PCB to equilibrate prior to reflow. In this way, the entire assembly sees nearly the same reflow conditions (peak temperature and time-above-liquidus) to form consistent solder bonds. Any potential thermal gradient increases as the physical size of As an initial starting point, the reflow profile shown in Figure 3 can be used with a typical range for the customer peak reflow temperature (Tp) of 235°C - 250°C.

Caution: Please contact your solder paste manufacturer for exact solder profile requirements. When using thermocouples for profiling, it should be noted that So, you must analyze your target board first before creating a unique reflow profile. Make an virtual reflow profile. A virtual reflow profile is based upon soldering theory, the recommended solder profile from the solder paste manufacturer, size, thickness, cooper weight, layers of the board and size, and the density of the components. CNSMT not only sale new slim kic2000 reflow oven temperature profile, but also provide repair service for all types of the profile, So if your current device has any issue while operating, and don’t want to buy a new one, then you can send to us help repair. common reflow process used today because of its low operational cost, easy and contin-uous operation, and ability to accurately control the heating and cooling profile. Convection reflow can be used in conjunction with infrared reflow and typically has multiple heating stages, so the assembly is slowly heated to the appropriate tempera-ture.

This paper presents experimental results on the effect of reflow profile on both 63 %Sn 37%Pb (SnPb) and 96.5%Sn 3.0%Ag 0.5%Cu (SAC 305) solder joint Jun 12, 2017 Reflow soldering is an assembly process for printed circuit boards (PCBs) in which surface-mount parts are placed on a PCB prepared with By using infrared (IR) reflow soldering, the heating is contact-free and the energy for heating the assembly is derived from direct infrared radiation and from G. Damage to components caused by the reflow profile and other reflow errors . temperature-time characteristic (= soldering profile) for the reflow soldering. See classification of reflow profiles as per J-STD-020 in Figure 2. below. Fig 2. Typical IR reflow profile with key parameters and classification – refer to IPC/ Recommended Pb-free Reflow Soldering Temperature Profile · Typical Pb-free Wave Soldering Temperature Profile. A second advantage of the tent profile is that it speeds the reflow process, since residence in the oven is reduced by the time formerly required for the dwell zone.
