Fact of the day

[Karl W4KRL]

Printed circuit board technology was invented by Paul Eisler, an Austrian
refugee to England in 1936. Its first significant use was in anti-aircraft
proximity fuses by the US Army. Eisler made little money from his invention.
His autobiography is "My Life With the Printed Circuit".

Prior to the PCB almost all construction was point-to-point except for a few
high-end and military products that used turret boards.
