Dark Packages Metal Shields and Shadowing in PCB IR Heating
Dark Packages, Metal Shields and Shadowing in PCB IR Heating Dark packages, shield cans and tall components can distort an IR temperature map, but their appearance alone does not identify the cause. Determine whether the pattern moves with the PCB …
Thermocouple Placement for PCB Infrared Preheat Profiling
Thermocouple Placement for PCB Infrared Preheat Profiling Place thermocouples where the process is most likely to fail, not simply where the wires are easiest to attach. At a minimum, the profile should cover a likely cold joint, a likely hot …
PCB Thermal Mass Predicting and Measuring IR Preheat Response
PCB Thermal Mass: Predicting and Measuring IR Preheat Response Board weight may indicate that one assembly requires more energy than another, but it cannot predict the IR preheat time on its own. Use prediction to rank the risks; use measurements to …
