Double Sided PCB (also known as Double-Sided Plated Through or DSPT) circuits were the gateway to higher technology applications. The advent of the plated through hole was quickly adapted, and it allowed electronic designs to expand in capability and shrink in physical size.
Today the Double Sided PCB technology remains the workhorse of the assembly industry. 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.
