Cleaning of PCB’S and PCA’S

Making electronic assemblies involves many chemical steps, and each step can leave behind harmful residues. If not removed, these residues can weaken the reliability of the printed circuit assembly (PCA). Cleaning helps get rid of these contaminants, making the assembly more dependable and easier to inspect.

In fact, many customer contracts require assemblies to be cleaned and tested for cleanliness. Meeting these requirements ensures the final product meets quality standards.

Manufacturers use two main types of assembly processes: those that include cleaning and those that do not. Both methods can create reliable products, but the post-soldering cleanliness designator allows customers and manufacturers to choose the best approach for their needs.

Keeping parts clean before and after soldering is crucial. Dirt and residues can cause soldering problems, while poor post-soldering cleaning can lead to coating issues, leakage, and corrosion.

When cleaning is needed, the process must remove harmful flux residues without damaging other materials or components. The right cleaning solution should get rid of both conductive (ionic) and non-conductive (organic) residues to keep the assembly reliable and long-lasting.
