Kevin, The Technical Devices Machine, the EVS is a stand alone system that can reclaim up to 75% of the dross weight as usable solder. It has a much more proven history than the Electrovert add on, as well as being lower priced. The Technical Devi

Norman- I would be pushing to get the real world to match the ideal world, in other words get your jobsetters to do the right thing. You are looking to incur more costs to justify not having to make people do their job right. A bit of training a

Dave F asked me for an update on the SRS we evaluated last month... I like this machine. Over 80% of your wave dross is actually good solder; you just can't get to it without some type of separating agent. I like the mechanical sepration method mu

Gyver: Lemme take a wack [if you�ll excuse the expression, given direction of the later discussion] at your questions. Q1. Will the baking of BGA or PCB cause more oxidation before the SMT process? A1. It certainly will not cause less oxidation,

Yeh, I worked at Wang Computer factory in a reclaimed fabric mill with wooden floors. One of the causes of grapping is flux loss. In their paper, Briggs and Laskey talk about flux loss due to spreading and suggest: * Graping is much less prevalent i

Now there�s a conundrum. You want the �best way to clean leads�, but you want to use the worst type of flux for cleaning leads. You say, �20% copper exposed� � * What happened to the solderability protection during this two-year storage? Wouldn�t

Frank, I am not talking about the masking on the PCB. I am actually talking about the masking on the solder side of the BGA. We have a very very high dollar BGA and are trying to reclaim alot for reuse. When we remove the BGA from the assembly, you

Dreamy, Adding chemistry to the wash section in a cleaner does have its advantages. It reduces the surface tension of the liquid and will remove contaminates such as fingerprints. It does however complicate the process in respect to water treatment

John: What�s the matter? Free gold � good thing for you, bad thing for your supplier. :^) Pre-tinning of gold plated leads is important to: � Prevent gold embrittlement of the solder joint � Determine if the leads are solderable prior to assembly (
