What quality results have been noted as a result of processing SMT boards, using no-clean paste, without the aid of nitrogen? How much effect does the inert environment have versus processing SMT boards in an air environment? We are currently equipped with an IR reflow oven and an IR convection style reflow oven. Neither are nitrogen equipped. We are also in the process of experimenting with no-clean fluxes at the present time. What are the preferences as far as fluxes? Currently we are readying ourselves to look at Kester 244-c, ESP, Indium, Qualitec, and Alpha. We have dense mixed technology boards and some 100% SMT boards. Need some help.
