But this solution also has the drawback of its limitation: in order to obtain more reliable bonding, a circuit board bonding pad needs to be subjected to a gold melting process or a nickel-palladium-gold process, so that the process cost is relatively high, and the environment is not protected; in addition, bonding has high requirements on the positions of the circuit boards, such as incapacity of forming an included angle between the two circuit boards, incapacity of forming a higher step, incapacity of being far away from each other, and the like, which bring limitation to the subsequent design; the bonding process is also required to reserve a process operation forbidden zone called a large area on the circuit board, and devices cannot be arranged on the circuit board of the part, so that the area of the circuit board of the part is wasted, and certain cost is also brought.
