Bridge Jumper - Automatic Assembly
Our jumpers are ideal for automatic assembly since they are delivered on reels ready for your pick and place machine.
The jumpers can be directly inserted as like any SMD component directly on the solder paste after which it can be reflow soldered. The surface usually consists of lead free tin but can alternatively be produced with a leaded chemical tin surface.
Other surfaces such as gold and silver are offered as well. As per request we can increase the tin construction so that a sufficient tin depot is produced allowing components can be directly hot bar soldered.
In addition we offer a suitable soldering system. Our standard types are 15 mm, 20 mm and 25-mm-wide components, with a robust foil which easily withstands reflow soldering.
Current Carrying Capacity
The components have an extremely good bending behavior and allow you to produce an electronic component assembly in 3D, assembly bending and later maintenance can be trouble and damage free accomplished.
The jumpers are available in assorted pin counts (see table) and have a pin pitch of .5mm and .93mm. Depending on size they are available in assorted reel sizes.
Footprints
Here we show you how to best construct your PCB to achieve an optimum soldering.
We recommend you implement these footprints in your layout this is much easier than working with single pads.
Layout Suggestions
Here are suggestions on how far apart the PCBs for the single types must be for a suitable assembly of the Bridge jumper.
Assorted Bending
Bridge jumpers are versatile and can be used in assorted projects. They are developed not to directly be bent to 90° angle but to distance the gap between two PCBs so they can be arranged at assorted angles.
Here are some examples:
Varied Rotations
Bridge Jumpers can also be used in varied rotations.

Bridge Jumper Short Pins
Above we have introduced our Bridge jumper with long connection pins.
The soldering pins have a length of 2 mm and fit in many available PCBs. Due to our constant construction and development we have advanced this product series to include an optional pin length of 1mm.
Thereby allowing for a greater space saving possibility.
Space Saving - Factory Reliable
All models from above can also be ordered with shortened pins. Please be aware that the foil covering will be lengthened by 2mm.
The following diagram represents the Bridge Jumpers with 15mm short pins. On page 16 is a diagram where you can compare the mass difference between the two.
Optimal Signal Transfer
Using our connection jumpers to connect PCBs it is very important, that signals are perfectly transferred.
The line characteristic impedance is responsible that the high frequency transference is cleanly transmitted. The finished jumper and assembly can be tested accordingly to your dimensions. We are able to measure a signal transference up to 2 GHz in our in house lab.
Evaluations are automatically recorded onto computer and the end result is then shown. This unique measuring method can not only show us if the theoretical dimensions are in order we can also see the results in the practical use.
Importance Of High Frequency
Systems which have an inhomogeneous impendence characteristic or are falsely dimensioned can cause shock areas.
These shock areas are responsible that certain frequencies can not be properly transferred. It is important especially with high frequency transference that it has properly conformed impedance characteristic.
PCBs can be electrically tested, but other connection pieces such as plugs, and cables are simply installed which can interfere with the signal transference and are often difficult to pin point.
