Wave soldering handles roughly 65% of through-hole PCB assembly worldwide—and for good reason. This guide breaks down the seven critical stages from flux application through rework, explaining how subtle shifts in wave height, conveyor speed, or preheat temperatures create defects like bridging, icicles, and poor hole fill. Get the full technical walkthrough with actionable fixes you can apply to your production line immediately.

If you’re still running the same wave soldering setup from five years ago, the 2026 market has shifted underneath you. This comprehensive guide cuts through the marketing noise with actionable guidance on equipment selection, lead-free compliance, total cost of ownership calculations, and the real specs that matter for your production line.
