EIA-476 Date Code Marking; EIA-RS-481 Taping/Leadless Components for Automatic Placement; RS-485 Electrical Characteristics of Generators and Receivers for Use in Balanced Digital Multipoint Systems (serial data communications) RS-494 A 1983 Binary Cutter Location (BCL) standard for CNC
Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process. The presence on an item of a recycling code, a chasing arrows logo, or a resin code , is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.
Non-SMD types of LED lighting also exist, such as COB (chip on board) and MCOB (multi-COB). Surface-mounted device LED modules are described by the dimensions of the LED package. A single multicolor module may have three individual LEDs within that package, one each of red, green and blue, to allow many colors or shades of white to be selected ...
The metric codes still represent the dimensions in mm, even though the imperial size codes are no longer aligned. Problematically, some manufacturers are developing metric 0201 components with dimensions of 0.25 mm × 0.125 mm (0.0098 in × 0.0049 in), [ 31 ] but the imperial 01005 name is already being used for the 0.4 mm × 0.2 mm (0.0157 in ...
1×6 pin header (one row) 1×6 female header (one row) A pin header (or simply, header) is a form of electrical connector.A male pin header consists of one or more rows of metal pins molded into a plastic base, often 2.54 mm (0.1 in) apart, though available in many spacings. [1]

This does have the potential to affect the thermal and electrical performance of the joints, so it can be helpful to consult the package manufacturer for optimal performance parameters. SMD pads can be used to reduce the chances of solder bridging, however this may affect overall reliability of the joints. Stencil design is another key ...
