The particularly space-saving board-to-board connectors enable high-speed data transmission of up to 40 Gbps and a current carrying capacity of 0.5 A per contact. The floating version offers particularly high tolerance compensation during insertion and in the inserted state. This gives you the choice between a rigid and floating connection with a compact 0.635 pitch.

How can the solder contacts on the FS 0,635 board-to-board connector be tested after the SMD soldering process?

The contacts are routed under the housing, enabling automated optical inspection (AOI).


With which numbers of positions is the FS 0,635 board-to-board connector available?

The FS 0,635 board-to-board connector is available with the following numbers of positions: 20, 40, 60, and 80.


Do the vertical items have a suction pad for automatic PCB assembly?

Yes, all standard vertical items in tape-on-reel packaging have a suction pad. The position and size are specified in the TecDoc Packaging (i.e., in the technical packaging drawing) in the download area for each item. The suction pad is removed after the reflow soldering process.


Are both mating partners designed as floating variants to enable floating?

As a rule, only one side of the plug connection is designed as a floating version and the counterpart is rigid. This already covers a very large tolerance range. The floating female connector strip can be combined with three rigid variants of the mal... View more

As a rule, only one side of the plug connection is designed as a floating version and the counterpart is rigid. This already covers a very large tolerance range. The floating female connector strip can be combined with three rigid variants of the male connector strip, so that three different stack heights between 8.0 mm and 12.6 mm can be realized.

Does the specified data transmission rate apply to all combinations?

No, the specified data transmission rate refers to an example combination. It may vary depending on the item combination. Factors such as different stack heights - due to longer or shorter contacts - influence the signal quality and thus the achievab... View more

No, the specified data transmission rate refers to an example combination. It may vary depending on the item combination. Factors such as different stack heights - due to longer or shorter contacts - influence the signal quality and thus the achievable data rate. We can work with you to optimize high-speed data transmission for individual applications. Feel free to contact us.

Position a1 (row a, pin 1) is marked on the item. Position 1 is also marked in the TecDoc drawings (product family drawing and packaging drawing). The orientation of the item for PCB assembly and the plug-in direction are thus clearly defined. The customer can provide a different definition in its own documentation.

Where can I find information on extended air clearances and creepage distances to realize the necessary voltage requirements in my application?

The minimum distances are specified in the technical data. We are happy to calculate distances for partially assembled connectors or between omitted pins (so-called death metal parts) on request. This means that increased voltage requirements can also be realized.
