Dr. Lee, For lead-free wave soldering, we are recommended to use SnCu0.7, why not 0.8 or more ?? Since SnCu0.7 has eutectic melting point at 227 deg C, does it mean with more Cu or less Cu, the melting point will be higher ?? Also, in lead solderin

I tried some SN100C from AIM... On only one array. It flowed well on the chips but did not like the finish on the SOT23's on the board. I did not have enough arrays to mess around, so we switched it over to SAC305 and had no issues. I'm guessing w

Sn/Cu/Ni is introducted to me in wavesoldering lead free process. Around in our industry, we have a plenty of info. about SAC but not on this alloy. The distributor showed me some information about this alloy including less dross, more shiny /smoot

I heard from Electrovert's engineers that the SnCu alloy has a really tight process window and is not very machine friendly. It is pretty much used exclusively by the consumer electronics folks. They�re always pinching pennies and are running, lets s

Not sure about Sn/Cu/Ni large market share here in Europe as we have a large part of the UK market with SACP0307 alloy 0.3%Ag introduced over Two years ago Also worked against Sn/Cu/Ni alloy with large TV Co and they went with 0.3%Ag due to reliabili

Is anybody out there using Sn99.3Cu0.7 for wave soldering? How does it look. (Cost is about the same as eutectic 63/37).

Anyone with definitive reliability data on mixing thru hole lead free terminations (SAC and Sn/Cu) with Sn/Pb solder. Seems like a lot of conflicting information

You as, "What data is available showing the long term reliability of the intermetallics of the solder joints?" Alloy||Microstructure Sn-Pb||Lamella or globules Sn-Cu||Sn-matrix, Cu6Sn5 needles or globules Sn-Cu-Sb||Sn-matrix, cuboids of SbSn and Cu6

Hi, Anybody apart from the solder manufacturer themselves or their distributors who have used this alloy for lead free wave solder ?

CEMCO Uk have done testing using SACX0307, SAC305 and Sn/Cu/Ni. The copper dissolution tests (report available) conducted at CEMCO showed that the lowest copper erosion rate was achieved by SACX0307. Regards Gerry
