Temperature Profile for Wave Soldering
Wave soldering temperature profiles refers to the time and temperature curve of the printed-circuit
board when processed in the wave soldering machine.
This is an important parameter for the wave soldering procedure. It will have a direct impact on
soldering efficiency and quality.
Wave Soldering Temperature Graph: Composition
The temperature curve for wave soldering is generally composed of three parts:
Preheating Area: The preheating zone is used for heating the circuit board, components
and to ensure the solvent elements in the flux are vaporized by heat. This will prevent explosions and
tin particles problems.
Soldering Area: The solder is melted in this area, so it fills and wets the joint. This
creates a solder connection that is fixed.
Cooling Zone: The zone is used for cooling and solidifying the solder, and preventing
defects in solder joints.
Wave Soldering Temperature Curve: What Is It For?
Control of welding quality: The wave soldering temperature is an important basis for
welding quality.
Soldering defects can be reduced by optimizing the temperature curve for wave soldering.
Increased production efficiency: Optimization of the wave soldering curve can reduce
soldering times and increase production efficiency.
Cost Control: Optimizing wave soldering temperatures curves can reduce defects and
scrap rates, and reduce costs.
Wave Soldering Temperature Curve Optimization
Optimize the temperature curve for wave soldering by considering the following factors:
Select the Right Temperature for the Time:
The preheating temperatures are too low and the solvents in the flux won’t be fully volatilized.
This will result in bubbles or tin particles. The components will be damaged if the preheating
temperatures is too high.
If the time for preheating is not long enough, the solvents in the flux are not completely volatilized.
This results in bubbles and particles of tin. The circuit board will overheat if the preheating period
is too long. This will affect the quality of the weld.
If the temperature of soldering is set too low, it will result in cold soldering. If the soldering
temperatures is too high the solder will overexpand, leading to bridging or pores.
Cold soldering can occur if the time for soldering is not long enough. Soldering too long will cause the
solder to expand excessively and result in pores, bridges, and bridging.
A temperature of cooling that is too low will result in a poor solidification, which results in cold
soldering. A cooling temperature that is too high will result in excessive shrinkage and pores.
The solder will fail to solidify properly if the time of cooling is shortened. This can result in cold
solder joints. The solder will shrink too much if the cooling time is excessive.
