The angle of load path between the balls and the inner and outer ring. Can be 15, 25, 30, 40 and 60 degrees. Larger contact angles tend to be reserved for high axial load applications such as ball screws.
contact angle = zero for full wetting contact angle = 180 degrees for immiscible liquids contact angle = 90 degrees for meniscus maintaining fluids. On adding surfactant to the oil-water interface the contact angle decreases. This can be understood as: surfactants reduce (interfacial tension): Cosine(contact angle) ~1/(interfacial tension), therefore as Cosine(contact angle) increases the contact angle decreases.
The angle of wetting between the solder fillet and termination or land pattern. A contact angle is measured by constructing a line tangential to the solder fillet that passes through a point of origin located at the plane of intersection between the solder fillet and termination or land pattern. Contact angles of less than 90° (positive wetting angles) are acceptable. Contact angles greater that 90° (negative wetting angles) are unacceptable.
A contact angle is the angle between the solid surface (plate or vessel) and the liquid surface.
The angle made between the bonding material and the bonding pad.
Angle between upper surface of solder and surface of substrate material at the perimeter of the solder. (Greater the angle better the wetting)
angle which encloses the tangent line on the drop shape from the three-phase point to the base line on the solid surface; the contact angle is a measure of the wettability of a surface or interface with a different liquid phase; the smaller the contact angle the better the wettability;
The angle between the contact surfaces of two objects when bonding. The contact angle is determined by the physical and chemical properties of these two materials.
Angle between a drop of liquid and a surface of a solid.
See Operating contact angle and Nominal contact angle
The equilibrium angle of contact of a liquid on a rigid surface, measured within the liquid at the contact line where three phases (liquid, solid, gas) meet. For example, water sheeting on glass has zero contact angle, but water beading on an oily surface or plastic may have a contact angle of 90° or greater.
The contact angle is the angle at which a liquid/vapor interface meets the solid surface. The contact angle is specific for any given system and is determined by the interactions across the three interfaces. Most often the concept is illustrated with a small liquid droplet resting on a flat horizontal solid surface.
