reflow profile - Swedish translation – Linguee

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. State Surface Mount Devices) for both Pb-free solder profiles and MSL classification procedures.

For the customer production reflow soldering process, the peak reflow temperature (Tp) has to be lower Reflow Profiles (per Jedec J-STD-020D.1) Profile Feature Sn-Pb Eutectic Assembly Pb-Free Assembly Preheat/Soak Temperature Min (Tsmin) 100 °C 150 °C Temperature Max (Tsmax) 150 °C 200 °C Time (ts) from (Tsmin to Tsmax) 60-120 seconds 60-120 seconds Ramp-up rate (TL to Tp) 3 °C/second max. 3 °C/second max. The reflow oven temperature profile is suited for characteristics of a particular circuit board assembly, the size and depth of the ground plane layer within the board, the number of layers within the board, the number and size of the components, for example. The reflow oven is used primarily for the reflow soldering of surface mount electronic components to printed circuit boards (PCB). If you fail to profile the oven correctly, then all of the hard work and effort that has gone into loading feeders, programming the machines, optimising the build and then running the production line will be wasted.

The reflow profile for these devices can be any-where between the upper and lower curves shown in Figure 4. Please note that the peak temperature is The RTS profile is not a cure-all for every reflow profile soldering issue. Also, the RTS profile cannot be used with all ovens or all assemblies. 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.

Solder profile for lead free Reflow Process Figure 1 Classification Reflow Profile for SMT components refer to IPC/JEDEC J-STD-020E Table 1 Classification Reflow Profiles Profile Feature Pb-Free Assembly Average Ramp-Up Rate (T Smax to T P) 3°C / second max. Preheat Temperature Min (T Smin) Temperature Max (T Smax) Time (t Smin to t Smax) 150 upward during the reflow soldering process. OSRAM Opto Semiconductors follows this guideline, and all its temperatures statements in the classification or in the reflow profile refer to the center of the package, which is measured at the top of the component. For SMD LEDs, especially for LEDs with lenses, the choice of two measuring profile for the specific solder being used. The manufacturer’s profile or the typical solder reflow profiles table in this document can be used as a starting point for profiling the process.
