Double-sided extender boards for testing Eurocards. The extender board plugs directly into a subtrack connector with the unique support/ejector mechanism at the front supporting the board under test.

DIN 41612 type B connectors
Solder resist coating to prevent solder bridging and finger staining

Support/eject mechanisms and terminal assemblies which may be soldered onto pads on each connector track for attaching test probes (typically for measuring voltage levels)

PC / VME Bus Boards

Prototyping boards manufactured from epoxy glass material to BS 4584 part 3 or 16. Card thickness is 1.6 mm. Copper is 305 g/m² (1 oz/ft²). Edge connector fingers are gold plated to a thickness of 1.5 microns. 1.0 mm (0.040 in.). Diameter holes are pre-drilled on a 2.54 mm (0.1 in.) matrix.

Microboard Pattern

Incorporates, on the component side of the card, a colander ground plane for maximum screening and glitch free high speed operation, and complete solder mask protection.
