Abstract
Abstract A solder-free circuit base plate made by changing the two integrated halves of conventional circuit base plate to two separate pieces side-exchangeably and removably joined by means of butterfly tenons and mortises made in the edges of different width so that different spaces and distances between the inserting holes can be arranged for making full use of the inserting holes and for inserting of different sizes of electronic parts in addition to the round hole design which smooths the insertion, prevents the hole from deforming and enhances the efficiency.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
126 words
A solder-less circuit base plate for the mounting of integrated circuit boards comprising at least two rectangular plates having a top surface into which are formed a plurality of cylindrical insertion holes arranged in a grid pattern, notched formed into said plates at the junction of the top and the long sides, borders between said grid of said insertion holes and the edges of said plate, said border being wider on one long side of said plate then on the other long side, and a plurality of mortises formed in the long sides of said plate, whereby butterfly tennons inserted into said mortises join individual plates together and whereby the distances between said grids can be adjusted by selection of the width of the adjacent margins.
