Biggest differnce is tooling. Tooling cost with a fixed pot - no tooling cost with programable "moving"pot. There are various way to control peel off with a moving pot. Depending on the machine, you can use either the Z axis or the actual pump spe

I think what Chunks meant is... TOOLING = THOSE POTS So basically, if some of your SMT or Through-Hole parts move around via a redesign or a respin, you will incur tooling costs (TOOLING is "THOSE LITTLE POTS FULL O' SOLDER.") When you're research

We have a Vitronics mySelective machine (model 6749, or "the Fat Bastard" as we affectionately call it). It's configurable with various combinations of "select wave" and "multi wave" pots. Ours has one of each. The "select wave" is for the most pa

Looking at the different Selective solder machines. Are there any process considerations with a moving pot versus a fixed pot. What about the angle and peel off on the moving pot?

Chunks, It sounds like you are referring to the construction of the solder pot. Not sure how that would require additional tooling cost? Thanks PCBHELP

Out of curiousity... What is the benefit of the selective solder machine that does NOT have a moveable nozzel? I am curious since this can be accomplished using a wave pallet. Thanks

Good afternoon! Typically, we normally recommend testing the pot, and adding either Sn/Ag or just Sn to keep it at bay. One nice thing about the solubility of Cu in Sn based alloys is that it should reach a theoretical upper limit of about 0.1%. I
