In the SMT (Surface Mount Technology) production process, the quality of stencil cleaning wipes directly affects printing quality and equipment maintenance efficiency. For purchasing personnel, selecting the right MPM stencil cleaning wipes not only ensures product yield but also reduces maintenance costs. This article systematically outlines the core features of MPM stencil cleaning wipes, key purchasing points, cost control, and risk mitigation strategies to help you make effective procurement decisions.
1. Core Product Features Analysis
-
Material and Process Advantages
MPM stencil cleaning wipes are made of 55% natural wood pulp and 45% polyester fiber composite. The natural wood pulp provides excellent liquid absorption, while the polyester fiber enhances tensile strength to prevent tearing and lint shedding during wiping. The wipes use a special spunlace process that bonds fibers without glue, resulting in a soft texture with minimal lint, effectively reducing the risk of stencil clogging. The basis weight is 56g/m², balancing absorption efficiency and thickness, suitable for high-speed wiping equipment. -
Specification Parameters
-
Width options: 250/300/330/350/400 mm to fit different equipment widths.
-
Tube inner diameter: 19.5mm ± 0.2mm
-
Tube thickness: 1.5mm ± 0.1mm
-
Roll length: 10 meters
-
Compatible equipment: Supports all MPM series and compatible printers.
-
For customized specifications, it is recommended to choose professional SMT stencil wipe manufacturers like Uster who support non-standard customization.
2. Key Purchasing Decisions
-
Width Compatibility
Ensure the wipe width matches the printing machine’s wiping mechanism width exactly, within a tolerance of ±3mm. For example, MPM Ultraprint equipment recommends 330mm or 350mm widths. -
Performance Testing Indicators
-
Oil absorption: Tested via standard oil immersion weighing method.
-
Tensile strength: Tested with an electronic tensile testing machine.
-
Lint shedding: Assessed through cleanroom vibration sieving.
-
Procurement staff can request samples from suppliers for in-house testing. Uster has its own professional testing labs and conducts strict quality control before delivery to ensure high product standards.
-
Supplier Qualification Review
-
Certification requirements depend on your company’s standards.
-
Prefer suppliers with over 5 years of SMT industry experience and key client references.
-
Must provide material testing reports, process flow diagrams, and on-site technical support capability.
-
Uster Group’s parent company boasts over 20 years of experience in this field, ensuring strong technical support.
3. Cost Control Strategies
For first-time purchases, compare multiple suppliers based on price and quality to select the best value option. For repeat purchases, compare with previous products and negotiate better pricing while ensuring equal or better quality, helping the company reduce costs and improve procurement performance. Avoid compromising quality just to lower prices, which can harm production and equipment safety.
4. Risk Mitigation
-
Storage Environment Management
-
Temperature: 15-25°C to avoid deformation of the tube.
-
Humidity: ≤60% RH since high humidity can reduce oil absorption speed.
-
-
Batch Consistency Verification
Sample 3 rolls per batch for quality checks, focusing on tube inner diameter tolerance (±0.2mm) and basis weight fluctuation (±2g/m²) to ensure batch stability. -
Environmental Compliance
Confirm compliance with RoHS 2.0 directives, especially regarding phthalate content, to ensure eco-friendly products.
5. Procurement Process Recommendations
-
Confirm technical requirements with process and equipment departments.
-
Shortlist 3 candidate suppliers.
-
Conduct at least one round of real-production environment sample testing (recommended continuous 8-hour verification).
-
Specify contract terms clearly, including quality penalties, minimum order quantity (MOQ), and payment terms.
6. Summary
Selecting MPM stencil cleaning wipes requires a comprehensive evaluation of technical compatibility, cost-effectiveness, and supply stability. Establish long-term supplier records, continuously monitor batch KPIs (yield improvement, downtime reduction), and leverage data-driven procurement to achieve cost reduction and efficiency improvements. As a leading domestic manufacturer of SMT stencil cleaning wipes, Uster adheres to the principle of “better quality at the same price, better price at the same quality,” offering free samples and professional technical support to help customers achieve efficient and stable production.
