Contaminants left on printed circuit boards (PCBs) after soldering like flux residues, ionic contaminants, and dust can cause corrosion, dendritic growth, and electrical leakage. Proper PCB cleaning improves reliability, extends product life, and reduces the risk of failure in the field, especially in high-reliability sectors like automotive, aerospace, and medical electronics.

ZESTRON offers several cleaners formulated to remove even the toughest no-clean flux residues. VIGON® N 680, ZESTRON® SD 301, and ATRON® AC 207 are top choices depending on your process (spray-in-air, ultrasonic, etc.). These products effectively clean no-clean fluxes while meeting IPC standards for cleanliness and ionic contamination.

Choosing between aqueous and solvent-based PCB cleaners depends on your cleaning equipment, board complexity, environmental goals, and process requirements. Aqueous cleaners like VIGON® A 250 are eco-friendly and ideal for high-throughput systems, while solvent-based options like ZESTRON® SD 301 work well for precision cleaning in limited-space applications or manual cleaning processes.

ZESTRON cleaning agents are designed to remove a wide range of contaminants, including flux residues (rosin, water-soluble, and no-clean), ionic contaminants, particulates, solder paste, and even polymers. Whether your issue is solder balling, dendritic growth, or electrochemical migration, ZESTRON has solutions tailored to your application.

Yes. ZESTRON formulates high-performance cleaners with low surface tension and optimized wetting to effectively penetrate and clean under low standoff components like BGAs, QFNs, and passive 01005s. Products like VIGON® NX 728 and ATRON® AC 205 are specifically designed to address the challenges of modern PCB miniaturization.

Semiconductor cleaning removes microscopic particles, organics, and ionic residues from wafers, interposers, and substrates. In advanced packaging, wafer-level cleaning, and 2.5D/3D integration, even trace contamination can impact device performance or yield. Precision cleaning ensures surface integrity, adhesion, and electrical functionality.

ZESTRON offers a dedicated line of high-purity cleaners for semiconductor and advanced packaging applications. Products like VIGON® SC 200, ZESTRON® HC, and HYDRON® SE 220 are engineered for processes such as wafer bump cleaning, stencil/mask cleaning, and die attach residue removal, ensuring compatibility with sensitive materials and ultra-clean requirements.

ZESTRON provides full technical support, including process development, material compatibility testing, and onsite or lab-based cleaning trials. Our global ZESTRON Technical Centers offer analytical tools, such as ion chromatography and SEM, to optimize cleaning parameters and validate performance for semiconductor and microelectronics manufacturers.

Yes. ZESTRON’s cleaners are compatible with a wide range of automated cleaning systems, including batch, inline, and tool-integrated solutions. They are also used in FOUP and carrier cleaning, ensuring particle and residue removal without damaging sensitive materials. Ask about formulations tailored for spray, immersion, and ultrasonic systems.

PCB cleaning typically targets flux residues and assembly contaminants, while semiconductor cleaning demands higher purity and the removal of ultra-fine particles and trace organics. ZESTRON addresses both by offering application-specific products, each optimized for its industry. Whether it’s inline aqueous cleaning for SMT or precision chemical cleaning for advanced packaging, ZESTRON has proven solutions for both environments.
