WELLPCB participated in the September 14-16 "Electronica India ", my company at HALL 12, Booth2105, exhibitors are PCB, PCBA, and other products. During the PCB exhibition, the company received hundreds of Chinese and foreign visitors, especially the company's PCB, PCBA attracted the attention of many viewers, and some also on the spot to establish cooperation intention, many customers concerned about the inquiry, there are many old customers come to the consulting firm New products, many customers on our company's small batch of one-stop service model that affirm and recognition.
Multi-Layer PCB
Obviously, a single or double layer PCB cannot be classified as a multi-layer PCB.

Two-Layer PCB
A two-layer PCB is also called a double-layer or double-sided PCB. It is basically made of an FR-4 glass epoxy substrate laminated with thin copper film or layers on both side. two-layer PCB is the simplest and the most economical PCB to design. A two-layer PCB can easily be manufactured by a professional PCB Prototyping factory (e.g. wellpcb.com), and can also be made at home. Two-layer PCB has only the top and the bottom copper layers.
Compared to a single sided PCB, it is much easier to route traces on a two-layer PCB by making use of through vias. These through vias electrically connect the top trace of the two-layer PCB with the bottom trace of the same board. The result is that, with two-layer PCB, you are able to conveniently and effectively place more PCB components on a single board using a smaller sized board as compared to a single layer PCB. With two-layer PCB, you can comfortably use the standard through-hole components to make your PCB or you can opt to use surface mount (SMD) Components. When designing your two-layer PCB, maximize the use of SMD Components as opposed to through-hole components. This makes it easy to manufacture your PCB and greatly cuts down on cost.
