SMD Surface Mount Components Introduced about 20 years ago, SMD: It is an acronym for Surface Mounted Devices, which is a surface mount device that is part of SMT (Surface Mount Technology) The And this has created a new era. From the passive components to the active components and integrated circuits, eventually become a surface mount device (SMD) and can be assembled through the pick and place equipment. For a long time people think that all the pin components can eventually be SMD package.

What is SMD
"At the initial stage of production of the electronic circuit board, the through-hole assembly is done by hand. After the first automated machines are available, they can be placed with some simple pin components, but the complex components still need to be placed manually for SMD wave soldering The
In addition to SMD also:
SMC: Surface Mounted Commponents
There are rectangular rectangular components, cylindrical chip components, composite chip components, shaped components.
SMD Architectural Design Office
SMD Architects is a world-renowned young architect design firm. SMD has been at the forefront of the world architectural design and construction industry, since its inception, completed design projects, including office buildings, banks and financial institutions, government buildings, public buildings, private homes, medical institutions, religious buildings, Entertainment and sports venues, school buildings and so on.
Surface mount precautions
A. Micro SMD surface mount operations include:
1. Print the solder on the PCB;
2. Use standard pick and place tools for component placement;
3. Reflow soldering and cleaning of the bumps (depending on the type of flux).
B. Micro SMD surface mount advantages include:
1. It is shipped in standard tape and package form for easy operation (according to EIA-481-1 specification);
2. You can use standard SMT pick and place tools;
3. Standard reflow process.
