Cooking and Freezing Processes; Food Tracker Profiling Systems; Datapaq Solar Tracker Systems. ” At this stage, the tin in the solder undergoes a “chemical reaction” with the copper (Cu) or nickel (Ni) on the pad, forming intermetallic compounds such as Cu 5 Sn 6 or Ni 3 Sn 4. Overall Equipment Effectiveness (OEE) Find common recipes for your assemblies, reducing changeover time. Automated profiling systems continuously monitor the process and create profiles for each assembly. Proper reflow profiling can improve or eliminate defects. Technical data sheets provided by the manufacturer will provide the operator all the information they need about the paste. (ECD): MEGAM. Lasky, Ph. ) and as narrow as 57 mm (2. Data sheets are also provided by the PCB and part manufacturer. Rework If we consider profiling a PCB for reflow in production, we are generally concerned with achieving an even Delta T ( T) across all of the joints being soldered. Only through proper profiling can the actual component temperatures within a reflow soldering process become known. In fact, as is discussed later in this paper, using the RTS profile generally will improve wetting. Thermal ProfileA thermal profile is a time versus temperature graph of the soldering process.
