PCBA is the English printed Circuit Board +assembly abbreviation, that is, PCB empty board through the SMT, and then after the whole process of dip plug-ins, referred to as PCBA.
PCBA refers to a processing process, can also be understood as the finished circuit board, PCB board on the process has been completed to calculate the PCBA. And PCB refers to an empty printed circuit board, there is no part.
Pcba=assembly of PCB. A variety of electronic devices through the surface packaging process assembled on the circuit board. Next is box assembly, will assemble the PCB with the shell and so on to assemble, PCBA forms the finished product. In other words, PCB board through the SMT, PCBA and then after the whole process of the dip plug-in, referred to as PCBA. This is commonly used in China, while in Europe and America the standard writing is pcb& #39; PCBA, that is, SMD PCB
PCBA manufacturing process is the combination of SMT processing process and dip processing process, according to the requirements of different production technology, can be divided into single-sided SMT process, single-sided dip interpolation process, single-sided mixing process, single-sided and plug-in mixing process, double-sided SMT mount Process and double-sided mixing process and so on.
PCBA, also known as printed circuit boards, printed circuit boards, often use the English abbreviation PCB (printed circuit board), is an important electronic components, is the support of electronic components, is the electrical components of the line connection provider. PCBA Because it is produced by electronic printing technology, it is called "printed" circuit board.
Prior to the advent of printed circuit boards, the interconnection of electronic components is based on wires directly connected to form a complete line. Now, the circuit board exists only as an effective experimental tool, and the PCBA has become an absolute dominant position in the electronics industry.
PCBA is widely used 10 years after the 60 's, its technology is also increasingly mature. Since Motorola's dual panel appeared, multilayer PCBA began to appear, making wiring and substrate area ratio increased.
As the production of PCBA is in the latter half of the electronic equipment, it is the downstream industry of the electronics industry. Almost all electronic devices require support, PCBA so printed circuit boards are the world's largest market share of electronic components products. At present, Japan, China, Taiwan, Western Europe and the United States as the main production base of printed circuit board.
