Continuing along the path that Brian took ... IPC-7525 gives design guideline for stepped stencils. It goes something like: * Stepped area SB GT 25 thou from pads located on the greatest thickness of the stencil * Pads in stepped area SB GT 35 tho

Have used IC for years, but I'm not familiar with that, ROSE maybe. Its a stretch, but maybe R/O/I would be rosin/resin, organic, or inorganic for the type flux being used?

According to J-STD-004 "Requirements for Soldering Fluxes", fluxes are classified by their chemical composition, activity level and halide content. In this scheme, each flux type is identified by a 4-character designator, where: * First two character

Rosin. A hard, natural resin, consisting of abietic acid [and pimaric acids in Europe] and their isomers, some fatty acids, and terepene hydrocarbons. Rosin is extracted from pine tree stumps. It�s an organic material distilled from oleoresin in p

First, don�t get distracted by �OA� and �NC� formulations. This is nomenclature. We want to discuss the issue of �activity�. J-STD-004 "Requirements for Soldering Fluxes" classifies fluxes by their chemical composition, activity level and halide c

OR: Stands for organic (organic acid based flux) with the absence of rosin and/or resin. If you want to know everything about the classification of fluxes get the J-STD-004 �Requirements for Soldering Fluxes� at following link: http://webvision.ipc
