Since the first PCB board was made by Paul Eisler in the year 1942, a lot of improvements have been made since then. These transformations have been seen in the increase in the layers of a PCB, development of better PCB materials, development of new PCB assembly methods etc. We will discuss some interesting facts about PCBs that very few pcb board Printed company china or scholars will talk about.
The PCB technology was started by an Australian inventor by the name Paul Eisler, who made a radio using the High Quality PCBs china which was able to work effectively. He invented this radio in the year 1942. Since then, continuous improvements have been made in PCB production. Mass production and usage of the PCB got rampant from the 1950s up to the present age where PCBs are being widely used and applied in many areas of the electronic industry.
The process of designing and manufacturing PCBs is dictated by the Ohm’s Law. So Engineers have to account for the resistance of the traces in making high precision PCB, because they can have degrading effects.
These two methods are the Through Hole Construction and the Surface Mount Assembly. The first one is the Through Hole Construction method. This method basically involves inserting PTH components into holes drilled into the PCBs and fixing the ends or leads to pads on the other side with metal solder. The other method of PCB assembly which is newer is the Surface Mount Assembly method. This method involves placing or mounting components directly to the surface of the PCB. It has replaced the Through Hole technology.
During oem pcb board Printed company of the printed circuit board, the analogue and digital circuits should be physically separated as much as possible. High level analogue signal are usually separated from other low level analogue signals and both are kept away from digital signals. This practice is observed so as to ensure that noise from the digital portion does not interfere with the sensitive analogue circuits. When the PCB is partitioned into digital and analogue regions the task of separation is simplified.
