Patent ID: 7378600

Claim:
A composite support for fabricating a prototype electrical circuit comprising: a rectangular planar board having a pattern of a plurality of rows and columns of through openings formed therein, said through openings having a center to center distance between neighboring openings of 2.54 mm, and said planar board having a maximum thickness of 1.0 mm, annular toroidal connection eyelets mounted in said through openings, each one of said toroidal connection eyelets including a first annular metal ring disposed on a top surface of said planar board, a second annular metal ring disposed on a bottom surface and located directly below said first annular metal ring, and a metal sleeve portion located in said through openings and extending and connected to said first annular ring and said second annular ring, said annular toroidal connection eyelets having an inside diameter of from 1.30 mm to 1.80 mm, a high temperature sheet material adhered to the entirety of said bottom surface of said planar board and adapted to be pierced by leads of electrical components inserted through said connection eyelets, a rectangular support tray having planar dimensions equal to said planer board and adapted for said planar board to be mounted thereon, said support tray having a rectangular well, a rectangular breadboad disposed in said rectangular well, said breadboard having a pattern of a plurality of rows and columns of receptacle openings corresponding to said pattern of through openings in said planar board and being aligned with said through openings when said planar board is mounted on said support tray, a plurality of spring socket contacts located within said breadboard and directly below said receptacle openings.
