ReflowArc: Solder Profile

ReflowArc is an offline process notebook for prototype labs and small SMT benches refining repeatable solder profiles. Keep oven setup, board thermocouples, paste windows, profile revisions, and visible defects in one repeatable run history. KEY FEATURES - Recipe and oven-zone revision history - Thermocouple placement evidence - Ramp, liquidus, peak, and cooling calculations - Paste and board-lot lineage - Visible-defect observation matrix - PDF run comparison brief - Optional local photos through Apple's Photos picker - Local PDF project brief - 230 original offline reference plates - No account, ads, analytics, tracking, subscription, or network requirement ReflowArc is a documentation and transparent arithmetic tool. It does not control an oven, validate a solder process, assess fumes or fire safety, prescribe temperatures, or replace material data, equipment instructions, and qualified process engineering.
