![]() ![]() High peak temperature can cause the damage of the component, damage of the assembly or detach of the pervious soldered components. ![]() Profiling is the process to determine the proper time duration and temperature a PCB assembly (PCBA) must endure throughout the reflow cycle1 (applicable to oven reflow and wave soldering. Thermal ProfileA thermal profile is a time versus temperature graph of the soldering process. The peak temperature should be controlled at 215☌ 5☌, with time above liquidus (183☌) at 60 seconds 15 seconds. Reflow soldering profiling warrants more discussion in detail. After reaching 150☌, the peak temperature should be reached as quickly as possible. Since larger components normally reach lower maximum temperatures during reflow than smaller ones, because of the different heat capacities, keeping them below their ratings may not be difficult, as long as 250 ☌ is used as the maximum temperature for the joints of smaller components. The spike zone of the RTS profile is the stage where the assembly reaches the reflow temperature of the solder. This means that 250 ☌ may not be usable as the maximum joint temperature for some components a lower temperature may be required. An oven temperature profiler is used to monitor the internal temperature of your Reflow oven, it is designed to provide accurate data about the temperature. The Auto-Focus database ships empty but starts making oven setup recommendations after a dozen profile runs. Although Intel BGAs are generally rated at 260 ☌, other components, especially large ones, may be rated at 250 ☌ or 245 ☌. Components are typically rated as per J-STD-020C (or later), based on their package thickness and volume. The global Reflow Oven market size was valued at USD 227.14 million in 2022 and is expected to expand at a CAGR of 0.23 Percent during the forecast period, reaching USD 230.28 million by 2028. Higher T g material is not necessarily more resistant to this damage, and must be tested for compatibility. If maximum solder joint temperatures exceed 250 ☌, PCB damage such as delamination and warpage may result when standard FR4 (T g =130 ☌) material is used. Optimum results can be achieved by identifying all aspects of the product characteristics, including component types, solder and board requirements, volume, pace, size, and thermal. A thermal profile is a time versus temperature graph of the soldering. A reflow oven is the ideal choice for several soldering needs. Reflow soldering profiling warrants more discussion in detail. (The Expresswire) - New Research Report 2023: Convection Reflow Oven Market research study investigates deep into the industrys revenue, volume, and size, analysis based on. 250 ☌ is recommended as the maximum temperature for all solder joints on the board, except for components with temperature ratings lower than 250 ☌. Ensuring proper reflow oven profiling can help to avoid costly production problems.
