Hi Patrick, thanks for the response. I might add some more information - we succesfully soldered some boards with the same settings of belt speed, pre-heat temp. etc. This batch of boards differs from the previous in a way that they are 4-layer. May

I've been looking for information on how, if at all, any of you treat water after a pcb batch wash. In particular, we have a Trident LD machine, using Zestron cleaning chemical. We have a carbon tank and two mixed bed media tanks as well as two 5 mic

Hi , The 4th stage in reflow soldering, the cool-down, I find is often over looked. A rapid cooling rate should give finer lead and tin structure with more bindings and thereby result in stronger solder joints. Can anybody give me some information
