PCB Tunnel Oven is an industrial thermal processing system designed for printed circuit board (PCB) manufacturing. It employs a conveyor belt to transport PCBs through precisely controlled heating zones, enabling uniform curing, drying, or soldering of coatings, adhesives, or solder paste. Key functions include:

​Thermal Curing: Solidifying solder paste during reflow soldering
or polymerizing protective coatings like solder mask ink.
​Moisture Removal: Pre-baking PCB substrates to eliminate moisture and internal stress before fabrication, reducing delamination risks.
​Efficiency: Continuous processing supports high-volume production with minimal manual intervention.

​Core Applications in PCB Manufacturing​
​Reflow Soldering:
Melts solder paste to form electrical connections between surface-mounted components and PCB pads, critical for PCB assembly (PCBA).
Temperature profiles (preheat, soak, reflow, cooling) are strictly managed to prevent defects (e.g., tombstoning, voids).
​Solder Mask Processing:
​Pre-baking: Partially evaporates solvents from applied solder mask ink before UV exposure, enhancing adhesion.
​Final Curing: Fully crosslinks the ink via thermal/UV energy to create a durable, insulating layer resistant to chemicals and abrasion.
​Substrate Pre-treatment:
Dries and stabilizes raw PCB laminates (e.g., FR-4) after cutting or washing, preventing warpage and blistering during subsequent drilling or etching.
