Hi Russ, Just a quick note to you the assembly houses, You say your transition will be the easiest, I would have to beg to differ after working with several CM's and working with there Wave solder lines and finding compatibale fluxes that will work

We have a customer that is transitioning to RoHS compliant assemblies. Their layouts are not changing from the old boards to the compliant ones so the stencils will remain unchanged. They are going through a transition phase where both will be buil

We've looked at our stencil under magnification after hand cleaning. There is some paste left behind. Machine washing removes all of the paste. Your best bet is to clean like normal, then look at the aps under magnification. Adjust accordingly (a
