Working with Others

Electronic assemblers, fabricators, inspectors and testers work independently. In large companies, they are part of an assembly team and are responsible for one stage of production, for example, assembly, visual inspection, or testing. In smaller companies they may be responsible for a wider variety of tasks and may even be part of a design team.

Continuous Learning

Electronic assemblers, fabricators, inspectors and testers mostly learn on the job. At larger companies they receive in-house training on new equipment, tools and procedures, including safety procedures. There may be seminars and workshops offered by suppliers. They may attend distribution shows to learn about new equipment and technology. They ask co-workers, supervisors and lead hands for information. They may look for information online including both electronic and hobbyist sites.
