When cleaning PCB assemblies, the primary goal is to remove contaminants from populated boards and hybrid circuits resulting from fluxes and improper handling. The use of engineered PCB cleaning solutions is essential to ensure flux residues are fully removed from the assemblies used in high-reliability applications and industries such as automotive, medical, aerospace, and military.

The targeted use of a cleaning agent substantially improves the integrity of subsequent processes such as bonding and conformal coating. Residues can cause improper adhesion of bonds that can lead to failures such as heel cracks or lift-offs. During the coating process, remaining residues can result in poor wetting and delamination that can cause assembly failures and ultimately lead to field failures.

These reliability risks are increased when using lead-free solder pastes as they contain more resins as well as aggressive activator systems and are soldered at higher temperatures.

VIGON N 680, based on the MPC® Technology (Micro Phase Cleaning), is a water-based, pH neutral cleaning agent specifically developed for the use in spray-in-air inline and batch equipment. VIGON N 680 removes a broad range of electronic assembly flux residues with an exceptional ability to penetrate and clean under low standoff components. Additionally, the cleaning agent provides excellent material compatibility, particularly with sensitive metals such as copper.

Advantages of VIGON N 680 compared to other cleaners:

Exceptional cleaning performance, specifically targeting low standoff component cleanliness
Easily rinsed yielding a wide process window
Excellent material compatibility with sensitive materials including copper and aluminum due to its pH neutral formulation
Performs well at low application concentrations in specific processes
Eco-friendly formulation eliminates the need for waste water neutralization
Halogen-free
