What it is

The Despatch CBB 2-27-1 is an oven.[1]

How it works

General reference — not yet source-verified

Thermal processing ovens such as the Despatch CBB 2-27-1 use forced convection or radiant heating to raise the temperature of a load. The oven chamber is designed to maintain uniform temperature distribution across multiple shelves or racks. Control systems regulate temperature, ramp rates, and dwell times according to process recipes.

Where it fits in the process flow

General reference — not yet source-verified

In semiconductor fabrication, baking ovens are employed after photoresist coating, after development, and during assembly and packaging steps. The Despatch CBB 2-27-1 can be placed in a photolithography area for post-coat and post-exposure bakes, or in a packaging line for curing encapsulants. The equipment processes wafers in batches rather than single-wafer, fitting into slower-throughput steps where uniformity across many wafers is required.

Applications

General reference — not yet source-verified

Typical applications for the Despatch CBB 2-27-1 include soft and hard bakes for photoresist, drying of cleaned substrates, curing of adhesives and underfill materials, and thermal treatment of thin films. The oven is also used for aging and stress-testing of devices.
