Little knowledge - Double Layer(Sided) PCB
Double sided PCBs (also known as Double-Sided Plated Thru or DSPT) circuits are the gateway to higher technology applications. They allow for closer (and perhaps more) routing traces by alternating between a top and bottom layer using vias. Today, double sided printed circuit board technology is perhaps the most popular type of PCB in the industry.
Benefits of Double Sided PCBs:
More flexibility for designers
Increased circuit density
Relatively lower costs
Intermediate level of circuit complexity
Reduced board size (which can reduce costs)
Applications of Double Sided PCBs
There are near limitless applications for old and new designs. Fine line surface mount, ultra high copper build, high and low temperature, Solder coated, Silver, and Gold finishes are just a few examples of DSPT applications.
The following are applications in which Double Sided PCBs can be used:
