ENIG and ENEPIG are meant to replace the more conventional coatings of solder, such as hot air solder leveling (HASL/HAL). While more expensive and require more processing steps, they have several advantages, including excellent surface planarity (important for ball grid array component mounting), good oxidation resistance, prevents 'copper migration', and suitability for movable contacts such ...
The gold is typically applied by quick immersion in a solution containing gold salts. This process is known in the industry as electroless nickel immersion gold (ENIG). A variant of this process adds a thin layer of electroless palladium over the nickel, a process known by the acronym ENEPIG. [19]
In surface-mount technology (SMT), the component is placed on the PCB so that the pins line up with the conductive pads or lands on the surfaces of the PCB; solder paste, which was previously applied to the pads, holds the components in place temporarily; if surface-mount components are applied to both sides of the board, the bottom-side ...
An unfinished surface is often called mill finish. Surface finishing processes can be categorized by how they affect the workpiece: Removing or reshaping finishing; Adding or altering finishing; Mechanical processes may also be categorized together because of similarities in the final surface finish.
Defense secretary nominee Pete Hegseth said Wednesday he won't drink "a drop of alcohol" if confirmed by the Senate to lead the Pentagon
NFL Commissioner Roger Goodell on Wednesday said the league is aware of a lawsuit that accuses musician Jay-Z of rape but said it is not impacting the NFL's partnership with the rap mogul's Roc ...
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 ...
Surface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. [1] It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane ).
