Where screws stand in the movement to lower profiles and more compact sizes
Technological innovations are leading to increasingly lower-profile and more compact semiconductor-based, electronic, and optical devices. This trend calls for smaller individual components to be used with the devices as well. The development of lower-profile and more compact semiconductor-based, electronic, and optical devices is now running into frequent obstacles, because the market offers so few "low profile screws" and "miniature screws" with a head height of 2 mm or less which are used in these components.
Furthermore, when component loss must be prevented, screws need relief cutting to keep them from falling out. In addition to lower profiles and more compact sizes, there is an increasing demand for CE compliant screws.
Why are NBK's low profile/miniature screws most suitable for lower profile and compact environments?
NBK low-profile screws are available in stock with heads ranging from a slim 0.5 mm to standard sizes. The wide range of materials includes steel, stainless steel, titanium, aluminum and resin among others.
NBK miniature screws are also available in stock as standard products. Thread sizes range from S0.6 to M2.6, and materials include steel, stainless steel, and resin. The abundant lineup of head shapes also includes pan head and flat head machine screws through hex socket head cap screws and set screws.
Additionally, we also stock captive miniature screws with relief cuts in Japan. Sizes run from M1.4 to M2.6, with head heights from 0.5 mm to 0.8 mm, suitable for compact precision devices, electronic devices, etc.
Low-profile screws: Printed wiring circuit
There is no screw head protrusion even with thin PCBs, and the thickness is effectively uniform.
Miniature screws: Cameras/sensors
The use of miniature screws allows main units to be made more compact than conventional products.
