Hi The issue is not the equipment or any other technical matter. The point is that the argument is about the 10 deg C higher melting point. The process window of SN/CU is somewhat smaller but manageable. I know Nihons web site but found not enough i

Some fella from Honda once used a potatoe to clean his pot. Siad it was a pretty good idea that he learned from the japs he works for. There was a thread here on The Forum once if you could look it up.

There are competitors to REL solder alloys from AIM. Tin-Copper-Nickel-Bismuth alloys (Nihon Superior) are an alternative option which do very well in thermal cycle testing. The reflow profiles required are similar to SAC305 profiles. You may als

Hi, I have done conversion from SAC387 to SCS7 with great results on process improvement with low cost. I see only the melting point is higher but still the solder pot temperature settings is 250�C to 260�C as SAC. If somebody think the temperature

Yes, all the leadfree solders are currently for consumer products. Military and aerospace industry haven't implemented leadfree yet. They are still study which to go! Maybe that time, we all can follow military std and having high reliability product

What are Resins, Solvents, Activators, and Thickening Agents in Solder Paste and what are their helpful and harmful effects? AND What are the purposes/properties and effects of Sn(Tin), Pb(Lead), Ag(Silver), Bi(Bismuth), In(Indium), Cu(Copper), Ni(

Yes! I would like to see the pics. I've already been looking into the SolderQuick system that Dave has recommended, but my customer wants some with 63/37 balls and some SAC305. SolderQuick doesn't have any SAC305 alternatives available as of yet. Tha

We use SN100C in our selective solder process. The 3 keys to proper hole fill are applying a proper amount of flux, heating of the pcb and solder temperature. If either the pcb or solder is not hot enough, you may not get good hole fill. To adjus

Hello, We are facing solderability issues on a particular lot of board. THe Nickel thickness measured with an XRF is around 400 U inches. Spec calls out for 130 u inches Nickel and 3 - 5 U inches gold over it. Assuming there is no porosity on the g
