Initially made the design and construction of the mold set up for the production of samples of metal parts as well as soldering tests. test with liquid solder all RMA type 3 category: NH-100VK-1, NF and NF
2107 1103.Results from the study found that the average Ratio value Spread NH-100VK-1 equal to 3.64 and the average Spread Factor equal to 82.44, rather than of the NF and NF 1103 2107 and NH-VK 100-1, the average contact angle is equal to the degree of is less than the 14.66 NF and NF
2107 1103.NH-100VK-1 conclude that better suit the solder on the surface of metal surfaces, metal Sn-58Bi copper.
