SMT Soldering
- overview or tutorial about SMT soldering, the SMD solder process for
surface mount components.
With the rise in the level of SMT or surface mount technology
used in electronics to the extent that traditional leaded components are rarely
used for mass produced electronics equipment, there has been a similar move
forward on soldering techniques for SMT.
Although in the very first days of using surface mount
technology, SMT, soldering was sometimes achieved manually, this is not feasible
in the vast majority of cases today for two reasons:
- The minute size of the components and tracks is too small for manual
operations and traditional soldering.
- The quantities of circuits normally produced could not be achieved using
manual methods.
SMT soldering process
There are several stages required to solder SMDs to boards.
However there are two basic methods of soldering that are used. These two
processes require the board to be laid out with slightly different PCB design
rules, and they also require the SMT soldering process to be different. The two
main methods for SMT soldering are:
- Wave soldering
- Reflow soldering
