Build an Arduino Uno Reflow Oven Controller for Flawless PCB Soldering

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Transform a basic toaster oven into a precision instrument for SMD soldering. The kit’s MAX6675 thermocouple amplifier and 25A SSR relay form a closed-loop controller that executes a custom reflow profile — preheat, soak, reflow, and cooldown — while a 1.8-inch TFT plots the actual temperature curve in real time. No guesswork, no cold joints, just repeatable results that make your PCB prototypes look professionally assembled.

What You'll Build

You'll wire and program a stand-alone reflow oven controller. The Arduino reads junction temperature from the Type-K probe, drives the SSR to switch the oven's mains power, and renders a live graph of the entire thermal cycle on the ST7735 display. Three buttons let you start a profile, navigate menus, and adjust target temperatures without a computer. Once built, the controller lives inside its own enclosure — ready to handle anything from 0805 passives to QFP-100 packages.

What You'll Learn

• Interfacing a thermocouple via SPI and converting raw bits into degrees Celsius
• Programming a PID or bang-bang algorithm to follow a multi-stage reflow curve
• Wiring a solid-state relay safely to switch 230V AC mains
• Drawing dynamic graphics on a TFT screen – axis, grid, and moving trace

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit suits B.Tech ECE/EEE students looking for a capstone project that demonstrates embedded control and power electronics. CBSE Class 12 students who have tinkered with Arduino will find the build challenging yet deeply instructive for school innovation contests. Makers at ATL Tinkering Labs and participants in Smart India Hackathon will get hands-on experience with industrial-level temperature profiling — a skill directly relevant to IoT and manufacturing tracks.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
