3.3 Flux, stating within the paragraph that “… Type H or M fluxes shall not [D1, D2, D3] be used for tinning of stranded wires.” Once the wires are tinned and assembled to their respective terminations, be it either a terminal, or a printed circuit board, other approved fluxes can be used to make those connections

: You ask a very interesting question regarding the selection of flux or fluxes and whether or not IPC provides information or dictates where certain fluxes can and cannot be used
