Overview of a printed circuit board production

Industrial printed circuit board production is a complex and multi-layered process that requires a wide variety of processing steps. Mechanical, chemical and photosensitive processes alternate. Each PCB is manufactured individually - although there are some basic processes and time-defined sequences - depending on the structure, material and requirements, the sequence or duration of the individual work steps vary considerably.

Not every manufacturer is able to deliver the same PCB in the same quality or time - machinery and know-how play an essential role in choosing the right partner. In the following we present a highly simplified overview of the most important processes. Depending on the type of PCB, its structure and material, the actual process can vary greatly - work steps take place in a different order or frequency or take different lengths of time.
