Many different processes require the use of an oven in the manufacture of electronic components and assemblies. These include curing sealants within the assemblies; potting; stress relieving the housing; curing an adhesive; and burn-in testing. Three key factors -- work space size, loading method and operating temperature -- should be considered when selecting an oven for processing electrical components and assemblies.
Some manufacturers test a small sample of a production lot while others test each individual component. Regardless of whether you choose to sample test or test each device, the size and number of parts to be processed in the batch must be determined to establish the necessary workspace size. A number of loading methods are possible and should be considered in view of production floor layout and available personnel. Parts can be loaded directly onto shelves in a shelf oven or placed on material-handling trucks that are loaded into a truck oven. These trucks can be used to convey the material through other processing areas in the plant.
