For those who are wondering what a printed circuit board is, it is a shining copper device carrying circuit and it is found inside your electronic devices. Be it your mobile phone, computer mouse, laptop or any other electronic device; the electronic board is an integral part of that device. Let us understand and know more about how it came into being. The evolution of different techniques used to design printed circuit boards began right from the twentieth century.
In the year 1904, the renowned scientist; Thomas https://www.hemeixinpcb.com/company/news/475-what-is-an-elic-hdi-pcb-any-layer-hdi-pcb.html Edison conducted several experiments of chemical techniques used for electroplating conductors on the linen paper. Paul Eisler from Austria invented the PCB in the year 1936. Initially, the invention of electrical board was done specifically for the radio set design. The military of USA also utilized the PCB design for the radio sets to be used by the soldiers during the world war.
As soon as the government of USA permitted the official usage of PCBs, commercial businesses also started making use of them. Earlier, when the circuit design was utilized by the army and businessmen, the method of point to point structuring was put into practice. The preliminary models used by the businessmen utilized wire traps as well as the turret boards. Before the technological advancement we have today, the circuit boards in the electronic equipment had wire leads and they were attached to the holes made on the boards. This technique of amassing electronic apparatuses is known as through-hole construction.
A new assembling process came into being in the year 1949 wherein two army officials implanted the leads of the electronic apparatuses into an arrangement prepared out of a copper foil. Thereafter; dip soldering was done and different parts were fused with each other. This method has become an integral part of the printed circuit board manufacturing process used by several manufacturers these days. However, there is a disadvantage of putting this method into practice. A lot of time and effort is wasted in making holes and several wires also get wasted after the manufacturing process comes to an end.
Nowadays, people often prefer to use surface mounted parts because the demand for small packed electronic devices is accelerating. One wouldn’t be exaggerating if one says that these electronic board creating techniques have opened up new doors for innovations and ideas aimed at the making of electronic devices which we use in our daily lives.
