Daily Maintenance Procedures for Reflow Soldering Machines

A well‑maintained reflow oven delivers consistent thermal profiles and long component life. Here are the daily maintenance procedures for reflow soldering machines recommended by SMTFullLine.

1. External Cleaning

• Wipe the conveyor rails and side plates with a lint‑free cloth.

• Remove solder balls or flux residue from the entrance and exit areas.

• Clean the chain or belt lubricants – use only high‑temperature grease.

2. Inspect Heater and Blower Vents

• Use a soft brush or vacuum to remove dust from heater module intakes.

• Ensure blower fans are not obstructed.

3. Check Thermocouple and Profile Stability

• Run a quick profile test (or check last batch logs).

• If zones drift more than 5°C, schedule calibration.

4. Remove Flux Residue from Conveyor Fingers

• Flux builds up on conveyor fingers over time, sticking to PCBs.

• Use a plastic scraper or alcohol wipe daily.

5. Verify Fume Extraction

• Check that the exhaust fan is working.

• Clean or replace filters (weekly, but inspect daily).
