Connector simplifies daughterboard replacement
A recent application for the ODU Mini-Fix card-to-cable connector system simplifies the safe replacement of daughterboards in an optical multiplexing project
A recent application for the ODU Mini-Fix card-to-cable connector system simplifies the safe replacement of daughterboards in an optical multiplexing project where the system operates at signal speeds up to 10GHz. In this application the daughter board has five ribbon cables, four 20-way and one 10-way, to be connected to the motherboard.

The Mini-Fix card-to-cable connector is designed to withstand hundreds of mating cycles with high contact security and mechanical stability
Card connector gains a flexible option
The ODU Mini-Fix card-to-cable connector can now be used with flexfoils in addition to ribbon cables
Normally these ribbons are connected with a sliding or pressure contacts but for this application it was decided to use insulation displacement type connectors (IDC) using the ODU Mini-Fix.
A surface mount header is soldered to the motherboard and because the Mini-Fix connector is easy to unplug, the expensive daughterboard can be replaced easily and with high security during service work Based on a 1.27 x 2.54mm contact grid the Mini-Fix is available in 10, 20, 30, 40 and 50 ways.
It has been designed for high mating cycles, has a contact resistance of less than 6mohm, a mating force of 0.18N/contact and has excellent impedance values.
Two types of latching are available if required: plastic side levers giving the component an assembly height of 12.7mm or a metal clip that reduces the assembly height to only 9mm.
Components in the range include straight and angled solder-in headers, straight SMT headers, IDC sockets to mate with the headers and solder-in PCB connectors.
Medical equipment, telecommunications systems, mobile GSM modules for vehicles, basestations, test equipment, industrial electronics, data collection systems and general instrumentation are just some of the other applications for this space saving connector.
