Why Preheat a PCB Before Soldering or Component Rework
Why Preheat a PCB Before Soldering or Component Rework? Preheating is useful when it reduces the temperature difference between a solder joint and the rest of the assembly without pushing another part beyond its limit. It is not necessary for every …
Bottom Side IR Preheat vs Hot Plate for PCB Rework
Bottom-Side IR Preheat vs Hot Plate for PCB Rework Choose bottom-side IR when non-contact access and controllable radiant zones suit the assembly. Choose a hot plate when a stable conductive path can be established without damaging features on the …
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 …
