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

Is there any benchmarking / report available on the industry regarding to the application of leadfree solder Sn(99%)/Ag(0.3%)/Cu(0.7%) e.g. Alpha Metals SACX0307 compared to SAC305? Thanks! Daniel

Of course it is needless to say the performance of SACX0307 is worse than SAC305, and also to some other lead free solders,eg SN100C & SCS7.

Hi, I have a lot of solder bridge in our wave soldering process.We use SACX0307 and Surf 11 flux.the SW mashine is Vitronics delta 6622.Itry to change flux and termoprofile but results is not god.Can you halp me - recommend me some flux or other adv

hi, we use SACx0307 since 2006 year.now , I want change this alloy with SN100C?I now that we must remuve all solder in the pot and cleen it.But that is very difficult process.What you think, can I just add new SN100C in the solder wave?What is the ri

Hello Greg, Glad to hear your success with the SACX0307 copy. By the way, does the P mean it contains phosphorus? Does yours also contain bismuth like the SACX0307 (according to their plumbing solder patent for X0307)? In response to your discussion

There are several alloys had been using in the industry. For SMT: most people use SAC305 For Wave: most of them use SAC305,SC100C,SCS7,and SACX0307. Of course, different alloy composition have its own recommended profile. There is no such rule tellin

We are experiencing a high incidence of what we call "black barrel" (to differentiate from black pad) with multiple contract manufacturers and PCB vendors. The PCBs are ENIG and during wave solder (SACX-0307) multiple thru-hole components are seeing

By and large, the industry has determined that SAC alloys are the "best fit" for replacement of SnPb in our industry. SAC305 seems to be the default alloy at this time. There are several other alloys out there, each with their own strengths and weakn

Hi everbody, I'm facing some soldering problems with a Diode (SMA) during wave soldering process. During this process almost all the time one of the component pads have no solder, according to the picture dsc000604 attached. Some considerations: * T
