SMT Assembly Boot Camp Master Workshop at STI Electronics, Madison, AL

October 10, 2022 - October 11, 2022

The SMT Electronics Assembly Class is a practical overview of the many different processes and materials used in through hole and surface mount technologies (SMT). It is a focused two-day long workshop, which provides students with the opportunity to learn and understand the processes, equipment, and materials used in today’s manufacturing of electronic assemblies. It is taught by an experienced and knowledgeable instructor who has worked in a variety of electronics manufacturing-related fields.

Combining a lecture, discussion, and some videos, this electronic assembly basic training workshop was designed to give a very comprehensive and complete “immersion” into SMT and mixed technology PCB assembly. People who are new to the field, as well as somewhat experienced personnel who want to “fill in the gaps,” have found this workshop to be a perfect solution.

As it runs only two days, it is extensive (and non-superfluous) without taking people “out of the shop” for an extended period of time: learn, absorb, and take that knowledge back to the manufacturing floor.
