Web3.6.2 Flux Classification The material of composition, activity level and halide content of fluxes shall be specified according to IPC J-STD-004 and identified with a flux designator stated thereof. 3.6.3 Solder Pool When specified, the solder pool characteristics of fluxed solder shall be determined in accordance with IPC-TM-650, Test Method 2.4.49. WebTwo flux formulas can differ greatly in performance, despite having the same QQ-S-571E and J-STD-004 classifcations. Solder pastes with specific characteristics can be used to solve technical assembly problems that other forms of solder do not. The following are a few examples of flux characteristics that modify how a solder paste performs.
