Reflow Curve

Reflow Curve is an offline-first thermal-profile logger built for electronics assembly techs who complete one named oven run at a time. Cold start opens a fullscreen reflow graph: temperature (°C) versus time, with colour-coded phase bands for preheat ramp, soak plateau, peak / time-above-liquidus (TAL), and cool-down. Set paste alloy and liquidus, then drag or type phase breakpoints so the curve matches the cycle you just ran—or the profile you intend to hit. Capture full run context without spreadsheets: • Paste & alloy library (Sn63/Pb37, SAC305, SN100C, low-temp BiSn, custom) with an automatic liquidus guide line on the graph • Phase parameter pad—ramp rate °C/s, soak temp/duration, peak temp, seconds above liquidus, cool rate—typed fields stay synced with the curve • Board identity strip: name/revision, layer count, paste lot, stencil note • Oven identity strip: name/model, zone count, fixture or pan used • Defect checklist tied to that exact run (tombstoning, bridging, voids, insufficient wetting, cold joints, polarity, solder balls) plus optional free-text outcome Browse a run library of past profiles with thumbnail curves. Open any run to resume editing or duplicate it as a new attempt. Stack two runs side-by-side on one graph to spot soak or peak drift. Start faster with profile templates (leaded wave-style, SAC305 production, low-temp rework, hand-batch toaster) and save your own. Share a plain-text run summary via the system share sheet. All data stays local—no account, no network required. Turn every solder-reflow cycle into a durable thermal curve plus paste, board, oven, TAL, and defect record so you can diagnose tombstoning, voids, and cold joints by comparing profiles—not by memory.

Initial production release of Reflow Curve. First release: fullscreen reflow-graph editor with draggable phase breakpoints for preheat, soak, peak, TAL, and cool-down. Paste alloy library with liquidus guides, board and oven identity strips, defect checklists per run, side-by-side curve overlay, profile templates, and plain-text share. Fully offline.
