Laptops typically use surface-mount CPUs, which take up less space on the motherboard than a socketed part. As the pin density increases in modern sockets, increasing demands are placed on the printed circuit board fabrication technique, which permits the large number of signals to be successfully routed to nearby components.
The term fine adjustment screw typically refers to screws with threads from 40–100 TPI (Threads Per Inch) (0.5 mm to 0.2 mm pitch) and ultra fine adjustment screw has been used to refer to 100–254 TPI (0.2 mm to 0.1 mm pitch). These screws are most frequently used in applications where the screw is used to control fine motion of an object.
LGA 1700 socket on a motherboard.. The land grid array (LGA) is a type of surface-mount packaging for integrated circuits (ICs) that is notable for having the pins on the socket (when a socket is used) — as opposed to pins on the integrated circuit, known as a pin grid array (PGA). [1]
The #6-32 UNC screw has a thread pitch of 1/32 in (0.031250 inches (0.7938 mm)).. The #6-32 UNC is a UTS screw specifying a major thread diameter of #6 which is defined as 0.1380 inches (3.51 mm); and 32 tpi (threads per inch) which equates to a thread pitch of 0.031250 inches (0.7938 mm).
Particleboard with veneer. Particle board, also known as particleboard or chipboard, is an engineered wood product, belonging to the wood-based panels, manufactured from wood chips and a synthetic, mostly formaldehyde based resin or other suitable binder, which is pressed under a hot press, batch- or continuous- type, and produced.

Typically, dementia is associated with classic symptoms like confusion and memory loss. But new research finds that there could be a less obvious risk factor out there: your cholesterol levels ...
SMEMA is an acronym for the Surface Mount Equipment Manufacturers Association.. In 1999 they merged with the IPC to form the IPC SMEMA Council. [1]One standard they have is for the wiring of communications between Surface mount technology producing machinery such as a Stencil Printer or a Pick and Place Machine on an Electronics production line.
A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.
