Abstract

A production line (13) for the one-sided and two-sided assembly of printed circuit boards with components consists of two successive sections (13a, 13b), each comprising a printer (4), at least one printed circuit board assembly machine (6, 7, 8) and a vertical reflow soldering furnace (14), in the direction in which the printed circuit boards pass through. One of each of the assembly modules (6, 7, 8) that are necessary for the desired product flexibility and which are allocated to the processing of different components is provided in the production line (13), said modules being distributed between the two sections (13a, 13b), between which a reversing station (11) is located. The soldering furnace (14) of the second section (13b) is preferably followed by another reversing station (11) which can be switched on and off.

Claims

1. A production line (13) for one-sided and two-sided assembly of printed circuit boards with components, the production line (13) consisting of two successive sections (13a, 13b), each comprising a printer (4), at least one assembly module (6, 7, 8) and a soldering furnace (14), in the direction in which the printed circuit boards pass through, characterized in that one of each of the assembly modules (6, 7, 8) allocated to the handling of different components is provided in the production line (13) and said modules are distributed between the two sections (13a, 13b).

2. The production line as claimed in claim 1, characterized in that the soldering furnaces (14) are vertical reflow furnaces.

3. The production line as claimed in claims 1 and 2, characterized in that a turning station (11) is arranged between the two sections (13a, 13b).

4. The production line as claimed in as claimed in claim 3, characterized in that a turning station (11) is arranged downstream of the soldering furnace (14) of the second section (13b).

5. The production line as claimed in either of claims 3 and 4, characterized in that the turning station (11) arranged downstream of the soldering furnace (14) of the second section (13b) can be switched on and off according to choice.
