The Next Generation Lead-Free Solder Paste
DKL Metals, in conjunction with Nihon Superior, are proud to announce the launch of a revolutionary new lead-free solder paste — SN100CV P608 D4.
Built on the patented SN100CV alloy formulation, this innovative product is designed as a direct drop-in replacement for traditional SAC305 alloys. With silver prices at record highs, switching to SN100CV offers exceptional performance without the cost burden associated with silver-bearing solders.
Like the rest of the SN100 range, it is a patented product and only available from licensed distributors.
