Class B delete code-named 35 B, 30 B, 25 B, 20 B 4 grades. Silver solder delete code 63 ag, 50, 60 ag ag three brands, increase code-named AG1.5, AG2.5 2 grades; - chemical composition made some modification. Code 63 AA bismuth content by 0.005% or less of the impurity elements is modified to 0.008% or less; Class A, code-named 63 A 55 A, 50, 60, A, A, silver solder and bismuth in solders to complete A phosphorous content of 0.01% or less modification for 0.020% or less, codenamed hf-solvated AG2 of silver content in silver solder by 1% ~ 4% ( Specific content is decided by both parties of supply and demand) is modified to 1.80% ~ 2.20%; --, delete the original standard "besides SB, BI, CU, impurities total is not more than 0.08%"; - delete in the required physical properties; --, increasing the production of the product sampling requirements; - delete the article Heavy, 250 + 25 g ". This standard reference to the American ASTM B32-2008 ISO9453 flux metal standards, international standards - 2006 "soft solder alloy chemical composition and shape" and Japan standard JISZ3282-2006 "soft solder chemical composition and shape" . Every brand the impurities limited strictly to brand the impurities in the above standard. Casting tin-lead solder physical properties of reference appendix A, compared with ASTMB32-2008 brands in annex B.
