Introduction
The IR Lead-Free Reflow Oven, model AS-5001, is tailored for Surface Mount Technology (SMT) production and maintenance. It employs far-infrared heating with precise microcomputer control to align temperature curves with SMT requirements. The oven accommodates various soldering pastes and features functions such as soldering, maintenance, and drying, along with automatic fault alarms.

Main Technical Parameters
The oven operates on AC220V (with an AC110V option) at a frequency of 50-60Hz, with a maximum output power of 600W. It utilizes a combination of infrared radiation and hot air for heating. The operating system supports both Chinese and English languages, offering automatic soldering and maintenance modes. The temperature process includes warm-up, heating, soldering, heat preservation, and cooling stages. The effective soldering area measures 180×120mm, and the oven's dimensions are 300×250×160mm.

Structure Introduction
The oven's structure includes a work salver for PCB placement, a display for parameters and status, and operational buttons. Power is supplied and protected via a power jack, fuse, and switch.

Function Key Introduction
- ON/OFF: Powers the machine on or off
- “Ç” “È”: Adjusts settings
- SET: Saves settings
- RUN: Initiates or exits operations

Temperature Curve Function
The temperature curve is vital for SMT production, consisting of five segments: warm-up, heating, soldering, heat preservation, and cooling. Each segment serves specific functions like moisture elimination, flux activation, soldering completion, solder solidification, and cooling.

Common Alloy Solder Temperature Curve Adjustment Parameters
Specific temperature settings are provided for various solder types, including low-temperature leaded and lead-free, mid-temperature, and high-temperature solders.
