PCBA = assembly of PCB. Various electronic devices are assembled on a circuit board by a surface encapsulation process. Next is the box assembly, the assembly is about to assemble the PCB and so on, forming the finished product. That is, after the PCB board empty pieces, PCBA and then through the DIP plug-in the entire process, referred to as PCBA. This is a commonly used in the domestic wording, and in Europe and the United States standard writing is PCB'A, is added to the ramp point. PCBA, is posted on the PCB.
PCBA Another statement refers to the assembly of printed circuit boards. That is, PCBA after the PCB board empty pieces, and then through the DIP plug-in the entire process, referred to as PCBA.
PCB refers to the circuit board, and PCBA refers to the circuit board plug-in assembly, SMT process.
PCBA may be understood as finished circuit board, also on the circuit board after the completion of the process can be considered PCBA.
PCBA = Printed Cirruit Board + Assembly.
That is, after the PCB board empty pieces, and then through the DIP plug-in the entire process, referred to as PCBA.
PCBA, also known as printed circuit board, printed circuit board, often use English abbreviation PCB (Printed circuit board), is an important electronic components, PCBA is the electronic component of the support, is the electronic component line connection provider. Because it is made using electronic printing technology, it is called "printed" circuit board.
Before the printed circuit board appears, the interconnection between the electronic components are directly connected by wires to form a complete line. Now, PCBA the circuit breadboard is only as an effective experimental tool exists, and PCBA in the electronics industry has become occupied by the absolute dominance of the position. At the beginning of the 20th century, people in order to simplify the production of electronic equipment, PCBA reduce the wiring between electronic parts, reduce production costs and other advantages, so began to study the way to replace the wiring method.
PCBA is widely used in the 60 years after the 60 years, its technology is also increasingly mature. And since Motorola's dual-panel available, multi-layer PCBA began to appear, so that wiring and substrate area ratio is more improved.
PCBA design mainly refers to the layout design, the need for internal electronic components, metal wiring, through-hole and external connection layout, electromagnetic protection, heat dissipation, PCBA crosstalk and other factors. Excellent circuit design can save production costs, to achieve good circuit performance and thermal performance. Simple layout design can be done by hand, but complex circuit design also need to use computer-aided design (CAD) to achieve, and the famous design software AutoCAD, OrCAD, PowerPCB, FreePCB and so on.
