Manual welding methods for SMT patch processing of leadless chip components: one by one welding spot, two, using special tools horseshoe iron head welding, three, using flat chip iron head quick welding
PCBA refers to a machining process, and the process on PCB board has been completed before it is calculated as PCBA. PCB refers to a blank printed circuit board without any parts, that is, PCBA is a finished board, PCB is a bare board.
As time goes by, the size of the high-performance chip increases, the number of Solder Bump increases, and the substrate becomes thinner and thinner. In order to improve the reliability of the product, it is necessary to fill the bottom.
Design the chip and integrate its digital and analog IP, and then optimize the placement of the chip in the package chosen and, in turn, the placement of the device on a multilayer PCB that is no longer sufficient.
PCB copy board and chip, the two are more like the relationship between the lips and teeth, think about it carefully, PCB copy board is like the shelter of the chip, without the shelter, the chip can only wander around, and can not play their role.
The chips are welded to the circuit board by soldering, and the circuit board is "wired" to establish the electrical connection between the chips.
Human body is a very sensitive organism, if disorderly implantation, the human body will reject many things, serious and even life-threatening, which is why ceramic circuit board is said.
Circuit board is to assist electronic components to better play their due performance, chipset mainly determines the function of the motherboard, and then affects the performance of the whole computer system, is the core component of the motherboard.
