Today in the market you can pcb board find a great variety of electronic component packages. It is common to find several types of packages for one device. For example you can find the same pcb board integrated circuit in QFP's and LCC's packages.
Thru-Hole
Are all those components that have pins intended to pcb board be mounted through a plated hole in the PCB. This kind of component is soldered to the opposite side pcb board of the board from which the component was inserted. Generally these components are mounted on one surface of the board only.

SMD/SMT pcb board (surface mount device/surface mount technology)
Are all those components that are soldered in the same side of the pcb board from which the component was placed. pcb board The advantage of this type of package is that it can be mounted on both sides of the PCB. Also, these components are smaller than the thru-hole type, which allows the design of smaller and denser printed circuit boards. These types of components are useful for frequencies up to 200 [MHz] (fundamental clock frequency).

BGA (Ball grid array)
These types of components are frequently pcb board used for high density pin integrated circuits. For soldering them to the printed circuit boards it is required to have specialized machinery due that the pins are made of solder balls that have to be melted for making the electrical contact with the pads.
BGA components pcb board are ideal for high frequency integrated circuits due to the very small parasitic inductances present in the joint between the pad pcb board and the balls. These type of components are very common in computer hardware like motherboards and video accelerator cards.
