Embodiment Construction

[0024] The invention relates to a treatment chamber for heat treatment in the manufacture of electronic components. During the manufacture of electronic components, the individual process steps (eg painting, assembly, soldering, painting, testing, etc.) are not hermetically separated from one another. Between the individual processing steps, the electronic components are transported on a conveyor between the processing stations / chambers. The processing chamber has openings for bringing the electronic modules into and out of the processing chamber. Therefore, the manufacturing process takes place in an open environment, which facilitates the workflow. However, heat treatment is carried out in a protective atmosphere to avoid oxidation. For this purpose, a local protective atmosphere is formed by a local supply of protective gas. Due to the open nature of the process sequence, this situation is a dynamic equilibrium of the shielding gas concentration at the processing point, ...

Abstract

An electromechanical curtain for a processing a chamber for heat treatment in electronic component manufacturing is disclosed. The processing chamber for heat treatment in the manufacture of an electronic component comprises at least one opening for feeding and / or removing the electronic component; and a means for supplying a shielding gas; the electromechanical curtain is characterized in that acontrollable protection device is arranged at the opening so as to reduce escape of protective gas from the processing chamber; and a control device capable of controlling the protection device is arranged, so that when the electronic component passes through the opening, the opening cross section of the opening corresponds to the cross section of the electronic component.

Description

technical field [0001] The invention relates to a device for heat treatment in the manufacture of electronic components. In particular, the invention relates to a treatment chamber as stated in the preamble of claim 1 . Background technique [0002] During the manufacturing of electronic components, various heat treatment processes such as soldering, drying and functional testing are performed at high and low temperatures. In order to avoid oxidation or freezing during the heat treatment, it is necessary to continuously or intermittently fill the treatment chamber with a protective gas, such as an inert gas such as nitrogen. [0003] In a typical electronic component manufacturing facility, components are automatically conveyed from one processing station to the next. For example, solder mask is applied to printed circuit boards and dried in processing stations after fabrication. Solder paste is then applied to the printed circuit board in another processing station, and ...
