Jason 1. How does salt change the heat transfer from the carrier ? (new one to me!) 2. Sodium Cloride is probably not a very good thing to put near a solder bath (contamination) or a pcb (corrosion). Ruben Sorry to say but the only way to improve the situation is to blow air across the wet carriers (evaporation is much faster at cooling), or buy more carriers. Ensure the carriers are dry before sending them back to the wave !

We have cooling fans mounted on both the exit end of the wave and atop my exiting conveyor mechanism. What type of composite material are you using. We don't have any heat problems coming out of the wave with our CDM materials.

We need to use them in order to protect the contact gold fingers. We are currently using conductive cooling system by submerging them in water but anyhow at the moment of using them they are still hot and wet. Is there any possibility of using convective methods and some kind of rolling conveyors or something?
