| Always experiencing dross in pot with different characteristic such as color, shape, dry/wet etc. Any paper, wetsites provide the more comprehesive explanation on its characteristic | Dross is a mixture of various things. The obvious ones are met

Robert: Several points: 1 Dross is a mixture of various things with no "fixed" composition: � The obvious things are metal oxides mixed with metal and this can vary in color with temperature and composition - remember some intermetallic oxides form

Try to process the composite pallet through the wave without any flux and view volume of smoke and if any residue is deposited in the wave when it exits. My guess is that the pallets are releasing some binders that are high boiling and this in turn c

In a previous life, we would send samples to our bar solder supplier and they would provide analysis. For contaminants, ICP (inductively coupled plasma) is a method we also used to determine composition. Google labs that have ICP capabilities.

| I am running composite fixtures on my wave solder machine and after about 500 passes each (1 month)they are showing serious signs of wear in that the composite surface is bubbling up and glass fibers are also starting to show. | The problem here

This is one of the biggest mistakes with the Lead Free process. We have all listened to the 'industry experts' and followed their advice and unfortunately got it wrong. Keep the dwell times (dependant on alloy selection) the same as Leaded so you are
