Single Sided PCB

These are the simplest printed circuit boards. Single-sided printed circuits do not require plating through holes and have a circuit pattern only on one side.

Double Sided PCB

Double sided printed circuits are one step up from the single-sided PCBs in their complexity. When fabricating double-sided boards, through-holes are usually required between the top and bottom pads; these pads are connected using a special copper plating process commonly referred to as Plated Through Hole (PTH). This process and the resultant products allow interconnections between layers through all holes.

Multilayer PCB

Multilayer printed circuits consist of four or more circuit layers bonded together by a thickness of insulating material called prepreg and core.

Hot Air Leveling (HAL) or HAL-lead free

Solder Mask over bare copper (SMOBC) and HAL-lead free (RoHS) or 63/37 Tin-lead over copper is the final finish. Copper is exposed by solder mask, is coated by Hot Air Solder Leveling (HASL).
