Your customer's cost will increase. Consider: * The majority of no-lead components have matte tin solderability protection. Bright tin, as mentioned by an earlier poster, has had reliability issues. Many component suppliers have documented their re

Most component fabricators don't properly understand the impact of soldering with pure tin solderability protection on components. Here's one that does: "The Effects of Board Attachment Processing on Sn Whisker Formation on Electroplated Matte-Sn on

Grant, Newer lead-free fluxes have 6%-10% solids content - more activator, therefore leave more "visible" residues. Old technology tin-lead fluxes got down to as low as around the 4%-6% range (I'm going off memory, so me might be wrong)... You'll

Matt solder mask finishes gives the widest process window in view of potential amount of residues when using No-Clean. Shiny (glass like) finishes are more sensitive to residues due to lower surface area compared to matt finish. If the shiny finish i

Just feel relieved that we didn't go to the matt on the use of "leaching" rather than "dissolution". And you thought this was easy, eh?
