Different designs of PCB layout have different constraints, leading to specific challenges; Typical layout guidelines for PCBs are area, frequency, and cost. For example, having the area as a primary layout design constraint can lead to a need for additional layers, more expensive package types, and more complex placement and routing.
A cost-constrained design, on the other hand, may require a balance between the number of layers, the area, the drilling density, the types of packages, and possibly the number of different drill sizes. Having clear constraints is necessary to estimate the PCB layout service, as this can drastically affect complexity.
Printed circuit boards are electronic circuits created by the assembly of electronic components on a non-conductive board and the creation of conductive connections between them. The creation of circuit patterns is performed using additive and subtractive methods. The conductive circuit is usually copper, although aluminum, nickel, chromium and other metals are sometimes used.
There are three basic varieties of printed circuit boards: one face, double face and several layers. The spatial and density requirement and the complexity of the circuit determine the type of board produced. Printed circuit boards are used in the manufacturing of commercial machines and computers, as well as communication, control and home entertainment equipment.
As we just mentioned, the most basic printed circuit board will have all the components on one side and all the copper wire on the opposite side. Since the copper circuit wire only exists on one side, we call it the single-side printed circuit board.
Due to the high demand and usage, PCBA manufacturing is one of the most sought after services offered by many companies.
