Kiln assembly and method for operating the kiln assembly

摘要

The furnace installation (1) carries out heat treatment for two regions (10,11) of a circuit board (5) by using a radiant heat (4) with various conservation temperatures. The region (11) of the circuit board is tempered at a moderate temperature by radiant heat sources (2) under AC1 temperature. The region (10) of the circuit board is conductively heated under AC3 temperature. An independent claim is included for method for operating furnace installation.
