Our Vapor Phase Asscon VP510
With the constant evolution of PCB assemblies bearing more complex components or having a more challenging substrate, the Asscon VP510 means that A Squared can complete the soldering stage of these products to a high standard using the vapor phase method.
What is Vapor Phase Soldering?
Vapor Phase soldering uses a special liquid called Galden which is heated up by the heating elements within the chamber to its boiling point where it turns into a fine vapor. This vapor then condenses over the printed circuit board assembly (PCBA), and the latent heat it carries is transferred across the entire board, melting the solder paste.
The temperature is able to be controlled precisely and efficiently due to how the heat is transferred which avoids any overheating of components and allows for uniformed soldering no matter what shapes or sizes.
The vapor phase is advantageous for more complex components as the heat is distributed evenly to all sides and none are then exposed to ‘one sided thermal stress’.
Whilst ensuring a controlled and even soldering, the vapor film also eliminates the potential for oxidation of the soldered section due to its high density.
Once the soldering process is finished the assembly is lifted from the vapor zone and starts the cooling down period where the Galden is evaporated completely and returns to liquid at the bottom of the VP510 to be cycled again.
The investment in the Vapor Phase VP510 means we can achieve the optimum results for a wide range of PCB assemblies with different board substrates and some which could be more complex or low-mass, heat sensitive assemblies.
