Hi DaveF, Thanks a Good to Great approach. I would still recommend getting another one, just in case. I am never too sure about how anyone follows procedures and maybe the start up just won't go well for some reason and you don't want to piddle a

RMA vs No clean

Electronics Forum | Thu Jan 16 15:16:52 EST 2003 | Mike Konrad

You are comparing apples to oranges. No-clean fluxes, because they are designed not to be cleaned off after reflow, contain very low solids. Normally, no-cleans have a solids content of 2% - 5%. Your basic RMA has a solids content of 15% to 30% (s

Scrapped Boards

Use and Restrictions of solder containing lead

Electronics Forum | Thu Jun 05 16:44:19 EDT 2003 | blnorman

The data we have is from an IBM report. Below 100�C the SAC reliability is almost double that of SnPb (-40 to 100�C thermal cycle). When the upper end temp is increased to 125�C the reliability drops to 75% of SnPb. I'd like to see the data that s

Another Lead Free question ?
