United Circuits history

For more than a century, the circuits functioned primarily as a way of assigning the justices and, after 1869, the circuit judges to service on the trial courts.

Only in 1889 was every district included within a circuit.

Herman Hollerith invented the tabulator in 1890 and would go on to found IBM.

In 1915 he filed a patent for the standard wall outlet plug that is still in use today.

1925: Charles Ducas, an American inventor, patents the first circuit board design when he stencils conductive materials onto a flat wooden board.

1936: Paul Eisler develops the first printed circuit board for use in a radio set.

The circuit judicial councils established in 1939 exercise administrative authority over all the federal courts within a circuit, and the circuit judicial conferences provide a forum for judges and lawyers to discuss the administration of federal justice within a circuit.

1943: Eisler patents a more advanced PCB design that involves etching the circuits onto copper foil on glass-reinforced, non-conductive substrate.

1944: The United States and Britain work together to develop proximity fuses for use in mines, bombs, and artillery shells during WWII.

The spread of information simply took time to travel before the Information Age. It took another six years in 1953 for this device to finally be used in products, but why so long? Back in those days, information was spread through journals, conferences, etc.

In 1956 the United States Army released their patent for the “Processing of Assembling Electrical Circuits.” Now manufactures had a method to both hold electronics and establish connectivity between components with copper traces.

Since 1977, Printed Circuits has been at the forefront of PCB technology.
