1-layer and 2-layer PCB – also called single- and double-sided – are mainly used in mass production and simple circuits. Because of manageable number of production steps, especially 1-layer PCB can be inexpensive and quick getting produced.
2-layer PCB typically have a through-hole plating of the both layers.2-layer PCB require, compared to 1-layer PCB, further production steps, which leads to a longer production time.
In these standard segments of single- and double-sided PCB Becker & Müller has been one of the top manufacturers and leading companies for years when it comes to combine highest quality with minimum delivery time.
