In 1995, a little over 50 years after the introduction of PCBs, they became a $7.1 billion industry for the first time. Just 5 years later in 2000, they became an over $10 billion industry, and since 2012 have reached over $60 billion worldwide. Before PCB design software was introduced, printed circuit boards were designed using clear Mylar sheets, up to four times bigger than the circuit board itself, on which designers would create a transparent photomask of the proposed design.
Turnkey PCB assembly has made professional PCB production and assembly much more efficient. The advent of machine-assembly for any size orders means that shops can assembly PCBs in a fraction of the time i
To maximize revenue, printed circuit board assembly services should be carried out with high standards for efficiency and precision. There are many important aspects of small batch PCB assembly, particularly in regards to its design and accuracy. Today, its possible to use printed circuit board design software to assist in these services. However, before this software existed, printed circuit boards were designed and created with clear Mylar sheets. Designers would create a transparent photomask of the design on a sheet that was about four times larger than the circuit board itself.
