In modern Surface Mount Technology (SMT), cleaning printed circuit board assemblies (PCBAs) is a critical functional requirement to ensure long-term reliability. The Cost of Poor Quality (COPQ) stemming from inadequate flux removal includes catastrophic field failures driven by electrochemical migration (ECM), dendritic growth, and parasitic leakage. As component densities increase and standoff heights under QFNs, BGAs, and BTCs shrink to 10-50µm, conventional cleaning methods fail. DCT delivers a 100% complete cleaning solution—integrating chemistry, machinery, and process control—to eliminate these risks and guarantee adherence to the strictest industry standards.
Achieving compliance with IPC-A-610, J-STD-001, and IPC 5704 standards requires overcoming the capillary barrier under low-standoff components. DCT’s Decotron® water-based fluids significantly lower surface tension to penetrate tight clearances and solubilize complex no-clean flux matrices. Designed specifically to synergize with our InJet® vertical Spray-in-Air systems, our fluids are naturally low-foaming. This prevents pump cavitation and micelle shearing, delivering maximum mechanical impact force directly to the board without leaving secondary residues.
Evaluating cleaning processes strictly on capital expenditure (CAPEX) ignores massive hidden operational costs. DCT solutions dramatically lower your Total Cost of Ownership (TCO) through continuous mechanical phase separation and advanced 2PR closed-loop filtration. By preventing premature bath saturation, Decotron fluids last up to three times longer than universal agents, cutting chemical consumption by 40% to 60%. The combination of reduced downtime, zero rework, and lower operating temperatures (20-45°C) yields a verified ROI typically within 12 to 18 months.
Eliminate the severe flammability hazards and high VOC emissions associated with Isopropyl Alcohol (IPA). DCT’s Decotron® portfolio features pH-neutral and mildly alkaline water-based formulations that are non-flammable, biodegradable, and free of halogenated compounds. Fully compliant with RoHS and REACH SVHC directives, our automated aqueous processes protect operator health, eliminate the need for expensive explosion-proof ventilation, and help your facility achieve critical ESG (Environmental, Social, and Governance) targets.
Selecting the optimal fluid depends on your solder paste formulation and board metallurgy. All fluids are optimized for high-pressure Spray-in-Air systems:
| Product Name | Primary Use | Key Feature |
|---|---|---|
| Decotron® CP 381 | PCBA Defluxing | Alkaline (pH 10-11) with integrated soft-metal corrosion inhibitors. |
| Decotron® 417XP | No-Clean Flux Removal | pH-Neutral, prevents white residues, excellent polymer compatibility. |
| Decotron® 411A | PCBA Defluxing | Alkaline, formulated for extreme metallic part protection. |
| InJet® 388 CRD | Cleaning System | Vertical Spray-in-Air technology eliminating shadowing effects. |
Components like BGAs and QFNs have standoff gaps of 10-50µm. Standard water cannot penetrate these gaps due to high surface tension. Decotron fluids reduce surface tension, allowing the chemistry to flow under the component and flush out active flux residues.
Horizontal spray systems often miss the trailing edges of tall components. DCT’s InJet® machines utilize a vertical Spray-in-Air architecture with rotating arms, ensuring 100% fluid coverage and direct impact force across the entire PCBA surface.
White residues are typically tin salts or partially solubilized no-clean flux matrices. They form when the cleaning fluid’s solvency is poorly matched to the paste. Decotron 417XP is specifically formulated with a novel solvent blend to completely dissolve these matrices without precipitation.
High-pressure pumps cause unmatched shear forces. If a fluid foams, it causes pump cavitation, resulting in pressure drops and poor cleaning. DCT designs its fluids to be “tenzide-free” or naturally low-foaming, maintaining maximum mechanical energy without secondary defoaming agents.
Unmodified alkalines can cause galvanic corrosion. However, fluids like Decotron CP 381 contain proprietary corrosion inhibitors that passivate soft metals, protecting copper, brass, and aluminum during the wash cycle.
