Introduction

The MPM printer, manufactured by ITW EAE Speedline, is a widely used machine in the electronics assembly industry, particularly for screen printing on printed circuit boards (PCBs). However, one common issue faced by users is solvent leakage, specifically with the solvents used in the printing process. This can lead to operational inefficiencies, environmental concerns, and increased costs. Understanding the causes, consequences, and solutions for solvent leaking in MPM printers is crucial for maintaining optimal performance and ensuring a safe working environment.

Causes of Solvent Leakage

1. Poor Seal Integrity: One of the primary reasons for solvent leakage is the degradation of seals within the printer. Over time, seals can wear out or become damaged due to exposure to harsh chemicals or mechanical stress. This wear can create gaps that allow solvents to escape.
2. Incorrect Maintenance: Regular maintenance is essential for the smooth operation of MPM printers. Neglecting to clean and inspect components such as hoses, fittings, and reservoirs can lead to buildup and eventual leaks. Operators should adhere to the manufacturer’s recommended maintenance schedule to prevent such issues.
3. Temperature Fluctuations: Solvents can expand and contract with temperature changes. In environments where temperature fluctuates significantly, this can lead to increased pressure within the solvent reservoirs, potentially causing leaks. Maintaining a consistent temperature in the workspace can help mitigate this risk.
4. Improper Handling of Solvents: Mishandling solvents during refilling or maintenance can also lead to spills and leaks. Operators should be trained in proper handling techniques and provided with the necessary tools to minimize risk.
5. Wear and Tear: Regular use of the printer can lead to wear and tear of components, including hoses and fittings. This gradual degradation can eventually lead to leaks, emphasizing the importance of routine inspections.

Consequences of Solvent Leakage

1. Operational Inefficiency: Solvent leaks can disrupt the printing process, leading to downtime and reduced productivity. Repairing leaks or cleaning up spills takes time away from production.
2. Increased Costs: Beyond the immediate impact on productivity, solvent leakage can increase operational costs. Users may need to purchase additional solvents to replace what has been lost, and there may also be costs associated with repairs or cleanup.
3. Environmental Concerns: Solvent leaks can pose environmental hazards, especially if they escape into the surrounding area. Many solvents are volatile organic compounds (VOCs), which can contribute to air pollution and have harmful effects on health.
4. Safety Hazards: Solvent leaks can create hazardous working conditions. Many solvents are flammable or toxic, posing risks to the health and safety of operators. Ensuring a safe working environment is paramount in any manufacturing process.

Solutions and Best Practices

1. Regular Inspections and Maintenance: Implementing a routine inspection schedule for seals, hoses, and other components can help identify potential issues before they become significant problems. Regular maintenance, including cleaning and replacing worn parts, is essential for preventing leaks.
2. Training for Operators: Providing comprehensive training for operators on the proper handling of solvents and maintenance procedures can significantly reduce the risk of leaks. This training should include emergency response measures in case of a leak.
3. Temperature Control: Maintaining a stable temperature in the printing environment can help minimize solvent expansion and reduce pressure buildup in reservoirs. Consider using temperature-controlled storage for solvents.
4. Use of Quality Materials: Investing in high-quality seals and hoses can lead to longer-lasting performance and reduce the likelihood of leaks. Ensuring compatibility between the materials and the solvents used is also crucial.
5. Leak Detection Systems: Implementing leak detection systems can help identify leaks early and reduce the risk of significant spills. These systems can alert operators to potential issues before they escalate.

Conclusion

Solvent leakage in MPM printers, such as those manufactured by ITW EAE Speedline, is a common issue that can lead to operational inefficiencies, increased costs, and safety hazards. By understanding the causes and consequences of these leaks, manufacturers can implement effective solutions and best practices to mitigate the risks associated with solvent leakage. With proactive maintenance, proper training, and investment in quality materials, manufacturers can ensure a safer and more efficient printing process.

The Mpm Printer Momentum II stencil printers are designed for high throughput and accuracy

Mpm Printer are engineered with proven technology that was built on our successful legacy MPM stencil printer machines.
From Mpm Printer head technology to vision system development, today’s leading Momentum series of stencil printers are ready
to meet the most exacting manufacturing challenges.

The RapidClean stencil cleaner is a high-speed stencil cleaning solution that improves cleaning performance and cuts cycle time. The RapidClean stencil cleaner provides precise wet/dry wipe transition and exceptional cleaning results with its paper over plenum design, venture vacuum, and patented roller solvent bar delivery system.

The Mpm Printer EnclosedFlow print head offers significant process and cost advantages over printing with metal squeegee blades, particularly for fine-feature printing. Solder paste is held within an enclosed chamber, and is directly pressurized during the print stroke to provide uniform and complete aperture filling for the full range of aperture sizes and fill types.

The Mpm Printer EnclosedFlow print head delivers superior volume/yield on fine pitch pads. Print fine pitch features such as 01005s and 0.3 mm pitch CSPs with up to 50% greater volume and 25% lower deviation that squeegee blades. The Mpm Printer EnclosedFlow print head ensures optimal aperture filling for fine pitch devices and crisp uniform printing with less waste.
