Wave Solder Conveyor Speed
A precise tool.
What is the Wave Solder Conveyor Speed & How does it work?
Wave soldering is a high‑throughput method for attaching components to printed circuit boards, where the board travels over a continuously flowing solder wave.
The conveyor speed determines how long each board remains in the solder wave, known as the dwell time, which must be sufficient for flux activation and reliable solder joints.
v = \frac{L}{t \cdot f}
v = conveyor speed (mm/s), L = conveyor length (mm), t = desired dwell time (s), f = flux activation factor (dimensionless)
Adjusting the flux activation factor accounts for variations in flux chemistry and temperature, allowing manufacturers to fine‑tune the speed without compromising joint quality.

Frequently Asked Questions
What is the formula for calculating wave solder conveyor speed?
The formula is v = L / (t * f), where v is conveyor speed in mm/s, L is conveyor length in mm, t is desired dwell time in seconds, and f is the flux activation factor.
How does conveyor speed affect wave soldering?
Conveyor speed determines the dwell time of each board in the solder wave. Proper dwell time ensures sufficient flux activation for reliable solder joints.
What is the role of flux activation factor in this calculation?
The flux activation factor (f) accounts for how quickly the flux becomes active and effective at creating good solder joints, influencing the required conveyor speed.
How do I adjust the conveyor speed for different board sizes?
For larger boards, you may need to increase the conveyor length or decrease the speed to ensure adequate dwell time for proper soldering.
What are the consequences of setting the conveyor speed too high?
Setting the conveyor speed too high can result in insufficient dwell time, leading to poor flux activation and unreliable solder joints.
Can this calculator be used for all types of wave soldering machines?
This calculator provides a general guideline. Specific machine parameters may require adjustments based on the manufacturer’s recommendations.
How often should I recalibrate the conveyor speed settings?
Recalibration is recommended whenever there are changes in board design, flux type, or soldering process conditions to maintain optimal solder quality.
