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).
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).
Flash Gold

Hard Gold (contact / bonding)
Gold fingers for contact purpose, Pads for rotary switch, Pads for Thermosonic Bonding, Lead free and RoHs compliant material.
Lead free & RoHs compliant materials, Extremely flat & uniform.
Electroless Nickel Immersion Gold finish (ENIG)
Contact surfaces. Minimum 1 micro-inch Gold over 100 micro-inch, Nickel Solderable surfaces, Electroless Nickel / Immersion Gold, Lead free and RoHs compliant materials, Extremely flat and uniform.
