In the contemporary field of electronic manufacturing, strippable adhesives have emerged as a critical temporary protective material, serving as an essential bulwark safeguard high-value, high-precision PCB substrates and electronic components during the production process against contamination and damage. Currently, the common types of strippable adhesives available in the market encompass thermoset, solvent-volatilizing, room-temperature curing, and UV-curing variants. These products undertake vital roles in the production processes such as solder protection, masking, and insulation. For instance, they shield gold fingers, connectors, screw holes, and other sensitive areas from the encroachment ofer, coatings, or chemical solutions during processes like wave soldering, selective coating, electroplating, and reflow oven.
Traditional peelable adhesives often face numerous challenges in practical applications:
• Low curing efficiency: excessive curing time at room affects production cycles and becomes a bottleneck for capacity.
• Poor user experience: improper viscosity control can lead to uneven coating, sagging, or equipment blockage, increasing operational difficulty maintenance costs.
• Inadequate protection reliability: insufficient heat resistance of the adhesive film in high-temperature welding environments can lead to cracking, carbonization, and loss of protective, even contaminating the welding pads.
• Residue risk: if residue remains after peeling, it may cause circuit short circuits or affect subsequent contact reliability.
• compliance pressure: with increasingly stringent environmental regulations, there is a higher demand for the environmental safety of materials.
The PM7005 peelable adhesive launched by Yask New Materials is a high-performance product designed for the needs of modern electronic manufacturing. Compared to traditional products on the market, the PM7005 exhibits significant advantages in multiple, with its core properties directly addressing the core pain points of the current industry.
Ancham PM7005 Product Comparison Application Advantages:
1. Excellent "Efficiency and Reliability" combination:
• Rapid c, speeding up production: PM7005 has the property of fast curing, completing the curing process in just 0.5 hours at 70-8℃, which is much faster than the 2 hours at room temperature. This significantly shortens the production waiting time, especially suitable for the high efficiency demand of automated production lines, many products on the market still rely on long natural curing.
• Short-term high temperature resistance up to 280℃: In instant high-temperature processes such wave soldering, PM7005 can provide reliable short-term high temperature resistance (280℃), effectively preventing molten solder from penetrating and ensuring the protected area remains intact. This performance index is superior to many products with a temperature resistance of only 250℃ or lower.
2. Excellent workability and ease of use:
• High viscosity, precise control: The product has a viscosity of up to 0,000 ± 5,000 mPa.s, which falls within the high-viscosity category. This property makes it less likely to drip when or brushed, ensuring precise coverage of the target area and forming a uniformly thick film of glue, avoiding the problems of low-viscosity products such as flowing and imprecise masking.
• Easy to peel, no residue: The cured glue film has excellent flexibility (elongation at break > 500%) and moderate tensile strength (2MPa, which means it can not only form a complete film but also be easily and cleanly peeled from various complex surfaces without breaking or leaving residual glue after completing the task, ensuring cleanliness of the product.
3. Versatile applicability and excellent safety:
• Compatible with manual and automated operations: The design of PM7005 meets needs of both manual operation for precise positioning and automated equipment for large-scale spraying, providing flexible process options for the factory.
• Safe and environmental-friendly, quality assurance The product does not corrode parts and is safe for PCBs and components. At the same time, the product meets environmental requirements, helping enterprises achieve green manufacturing. The completeSDS (Material Safety Data Sheet) also provides guidance for safe operation.
4. Stable product quality:
• High solid content (70 ± 5%): This less water or solvent, low shrinkage during curing, and the ability to form a more dense and better-protected film of glue.
Ancham PM7005 is a high-performance temporary protective material with precise positioning and outstanding performance. It directly addresses the pain points the electronic manufacturing industry in terms of efficiency, reliability, and user experience through its three core advantages: rapid curing, excellent heat resistance, and excellent ease of peeling
