    Product Details Data Sheet

    RT / Duroid 5880 copper clad laminates are usually fabricated by directly bonding Teflon components of the laminate to the surface of the foil. If electrodeposition is used, the spherical joint surface of ED foil will be mechanically interlocked with Teflon.

    Due to the thermal stability of RT / Duroid 5880 PCB, people seldom pay attention to the precise control of welding process, but sometimes they encounter joint problems in the process of solver. Especially in the assembly and rework process when using rough control of manual soldering tools.

    We designed an experiment to detect the effect of temperature on the bonding strength between copper foil and RT / Duroid 5880 plate. The test sample is a 0.062 inch (1.59 mm thick) RT / Duroid 5880 laminate covered with 1 oz ft2 (34 mm thick) ed copper foil. In the experiment, the samples were exposed to a series of different temperatures (from 182 ℃ to 371 ℃). The sample consists of 1 / 8 inch (3 mm) wide copper wire with a 1 / 4 inch liner at one end. The copper wire and pad are etched on a 2 inch square laminate specimen.


    The experimental measurement consists of three parts

    1. Cold peel strength: after the RT / Duroid 5880 sample floated on the solder for 30 seconds, the force required to peel the 1 / 8 inch (3.2mm) wide copper wire from the substrate at an angle of 90 ° was measured under the ambient temperature of 21 ℃.

    2. Thermal peel strength: after the RT / Duroid 5880 sample is immersed in solder and stabilized for one minute, measure the force required to peel 1 / 8 inch wide copper wire from the substrate at a 90 ° angle

    3. Thermal shear strength: peel the 1 / 8 inch wide copper wire from the substrate, leaving only the liner at the end, immerse the RT / duroid5880 sample in the solder and stabilize it for one minute, pull the 1 / 8 inch wide copper wire, and measure the tensile force required to make the liner separate from the substrate.


    The cold peel strength shows that when the temperature is close to the melting point of Teflon (327 ℃), the joint between teflon and Cu foil begins to be destroyed. At this temperature, Cu in contact with air is easy to oxidize. At the same time, when the phase transition of teflon begins, the protective effect of air isolation provided by PTFE bonding with the surface of metal foil will gradually lose.


    The thermal peel strength and shear stress show that the joint of Teflon and Cu foil is easy to be damaged at high temperature. Therefore, attention should be paid to manual soldering to avoid excessive temperature or stress.


    Rogers 5880 PCB material is manufactured with the same high-quality, reliable materials and processes as Rogers, enabling Rogers to win important awards from high-frequency material manufacturers. In some designs, the dielectric properties of the PCB are critical. Whether it is a high-speed PCB, RF PCB, or microwave PCB, you will find that PCB prototypes require more PCB dielectric properties than standard FR-4 cannot provide. we know. This is why we use Rogers 5880 dielectric material. These new low-loss dielectric materials mean higher performance for demanding PCB prototypes.
