Eurocard Extender Boards

A range of Double-sided & PTH & Multilayer extender board assemblies. An extender board kit, part no. 188-27542, allows 3U extenders to be combined in any arrangement to 6U or 9U high. See selection table below for alternatives.

The double-sided range, in either 64/64 or 96/96, is assembled with front and rear DIN 41612 connectors and supplied complete with ejector arms.

Features:-

• Provides support/eject mechanism to ensure the daughter board remains captive within the guides when ejecting and that the correct connector breaks when dismantling.
• Solder resist over all tracks to prevent contaminants from causing cross-talk between tracks.

See below for the selection table

Part Nos.:-

3 & 6 layer Multilayer extender boards with 4 separate Vcc power rails for hard wiring and test point/jumpers on all tracks for signal testing.

The super version, in 96/96 format only, is supplied as per the standard format but also including gold plated wirewrapping pins, jumper links and logic analyser reverse DIN connector.

Features:-

• Expandable height in multiples of 3U, i.e. 3U, 6U, 9U etc. is achieved by simply adding a standard divider plate assembly as required, part no. 188-27542
  
• The ability to mix different types of extenders on 3U upwards to suit a particular bus system
  
• Suitable for 160, 220 & 280mm deep systems
  
• Maximum track widths with a copper plating thickness of 70 microns in order to minimise voltage drop
  
• DIN connector outer rows 1abc, 2abc, 31abc and 32abc have extra wide tracks to match power rails on most standard bus systems, i.e. Vero's Microbus range
  
• Voltage and current measuring facilities available by either simply breaking tracks and pinning for the addition of jumper links (see illustration) or using the fully assembled super version
  
• Standard versions provide the facility for mounting a backplane stub terminator or logic analyser to the side of the board as required. This is supplied complete with the super version.
  
• Provides support/eject mechanism to ensure the daughter board remains captive within the guides when ejecting and that the correct connector breaks when dismantling
  
• Solder resist coated to prevent solder bridging of joints and finger staining
