What is the difference between PCB and PCBA
What is a PCB
PCB = printed circuit board;
PCB is an important electronic components and support of electronic components, electronic components is the carrier of electrical connection.Because it is made by electronic printing, it is called printed circuit board.
What is a PCBA
PCBA = the assembly of PCB.
Various electronic devices are assembled on the circuit board by surface packaging technology.Next is box assembly, which is to assemble the PCB with the shell and other components to form the finished product.That is to say, the empty PCB board passes through the SMT upper part and then the entire manufacturing process of the DIP plug-in, which is called PCBA for short.This is A common way of writing in China, while the standard way of writing in Europe and America is PCBA, with oblique points added.A PCBA is a pasted PCB.
What is the difference between PCB and PCBA?
PCB refers to the circuit board, and PCBA refers to the circuit board plug-in assembly, SMT process.
One is the finished board and one is the bare board
Printed Circuit Board (Printed Circuit Board) is called “Printed Circuit Board”. It is made of epoxy glass resin material and can be divided into four, six and eight layers according to the number of different signal layers.The chip and other patch elements are pasted on the PCB.
PCBA may be understood as finished circuit board, that is, PCBA can only be calculated after all the procedures on the circuit board have been completed.
PCBA =Printed Cirruit Board +Assembly.
That is to say, the empty PCB board passes through the SMT upper part and then the entire manufacturing process of the DIP plug-in, which is called PCBA for short.
Printed circuit Board PCB(Printed Circuie Board) is the abbreviation of Printed circuit Board, usually in insulating material, according to the predetermined design, produced Printed circuit, Printed components or two combinations of conductive graphics is called Printed circuit.And in the insulation substrate to provide electrical components between the conductive graphics, known as printed circuit.So the printed circuit or printed circuit of the finished board called printed circuit board, also known as the printed board or printed circuit board.
