Problems solved by technology

In addition to the static pressure already present, this can lead to build-up pressure and uneven flow rates at the nozzle opening
A further consequence is that the output of the treatment liquid is not uniform

Embodiment Construction

[0039] The nozzle arrangement shown in FIG. 1, which is particularly suitable for use as a flow nozzle in an electroplating system in which printed circuit boards pass through horizontally, comprises a housing 2 substantially in the shape of a parallelepiped. Arranged on the rear of the housing 2 is a connection sleeve 1 which is coupled to the fluid feed opening of the housing for feeding in process fluid. On the side of the casing 2 opposite to the workpiece to be processed or the product to be processed, rows of staggered slits or holes are provided, and these slits or holes form an output opening 8 for the processing liquid. In the illustrated embodiment, all slit delivery openings or holes 8 have the same dimensions, ie have the same length and width or the same diameter. However, different dimensions can also be chosen in order to produce a predetermined spray or stream pattern.

[0040] Inside the housing 2 there is provided a wedge-shaped insert 3, preferably made of ...

Abstract

The invention discloses a nozzle device, which is especially used as a flow nozzle of an electroplating system for printed circuit boards passing horizontally. The nozzle arrangement comprises a longitudinal housing (2) having at least one fluid feed opening for feeding a treatment liquid to treat workpieces (such as printed circuit boards), and preferably a plurality of The slit-type fluid output opening (8) for releasing the treatment liquid. A fluid channel (5) is formed in the housing (2) for feeding treatment liquid from the fluid feed opening to the fluid output opening (8). In order to obtain as even as possible a flow rate of the treatment liquid at the fluid output opening (8), (a) the throughflow of the fluid channel (5) for the treatment liquid decreases continuously from the fluid feed opening in the longitudinal direction of the housing (2) , and/or (b) a storage chamber is provided before the fluid is output from the fluid output opening (8).

Description

technical field [0001] The present invention relates to a nozzle device, which can be used in the occasion of treating a workpiece with a treatment liquid, or in the occasion of flooding a treatment liquid into a corresponding treatment bath. In particular, the present invention relates to a flow nozzle arrangement which can be applied, for example, in continuous systems for the wet chemical treatment of printed circuit boards. Background technique [0002] Nozzle arrangements of the type described are widely known. Thus, for example, such nozzle arrangements are used in continuous systems for the wet-chemical treatment of printed circuit boards in order to achieve as rapid and uniform a treatment of the passing printed circuit boards as possible. For this purpose, in a known form, various such nozzle arrangements are arranged above and / or below the horizontal position in which said printed circuit board passes, and diagonally opposite the direction of passage of this print...
