Double-Sided PCB Manufacturing<\/h1>

FLJ manufactures custom double-sided PCBs with copper circuits on both faces of the board and plated interconnections where the design needs them. We supply two-layer bare boards for prototypes and production, with the selected laminate, copper, holes and solderable finish. Component sourcing and assembly can continue the build when you need a populated board.<\/p>

Two Copper Layers, One Connected Circuit<\/h2>

A double-sided PCB has a copper circuit on each side of an insulating core. It is also called a two-layer PCB: the layer count describes the conductive copper, rather than the solder mask, printed markings or number of faces populated with components.<\/p>

The second copper face gives connections another route through the layout. A track can pass through a plated via to the opposite face, continue around a crowded area and reach another component or connector. For example, a connector signal can start on the top copper, pass through a via and continue on the bottom toward a control device. A separate top-side connection can cross that bottom route without touching it. This illustrates a routing choice rather than a measured customer design.<\/p>

This extra routing space can support a smaller outline or a denser circuit. It does not require components to occupy both faces: a board with components on one face can still use both copper layers for its connections. The component layout and soldering route determine the assembly arrangement.<\/p>

FLJ fabricates the two copper patterns, their plated connections and the finished board shape as one bare-board product. For simpler circuits, our single-sided PCB service provides a one-copper alternative; designs needing additional routing or reference layers can move to a multilayer construction.<\/p><\/div>
