TWO VERSIONS OF HIT ARE AVAILABLE:
RECTANGULAR HIT AND LINEAR HIT
has been designed to optimise the space available on a Double Eurocard daughter board. Two sizes are offered, Size A (128 contacts) and Size B (204 contacts). Eight Size A or four Size B connectors (or a mixture of both) can be accommodated. Using Surface Mount components both sides of the child board can be populated. The clearance between the underside of the child board and topside of the daughter board is 4.35mm. the child board is polarised.
LINEAR HIT
provides the opportunity for the child boards to be of variable lengths and widths and is available in three sizes, 16, 32 and 64 way. The standard clearance between child board and daughter board is increased to 6.35mm permitting thru board or surface mount components to also be mounted on the daughter board. In addition, the 32 and 64 way sizes can also be supplied with a 10mm clearance to cater for larger size components, along the surface of the p.c.b. The Linear HIT may be edge mounted or in-board mounted and can be polarised in a number of alternative positions in respect of the child board.
