In recent exchanges with customers, many friends will ask some questions, roughly pointing in one direction, that is, what is the difference between PCB and PCBA, can not distinguish circuit board manufacturers in the production of circuit boards in the main business, resulting in imprecise choice of manufacturers, a waste of a lot of time and energy. Today as a professional production circuit board 13 years of pcb circuit board manufacturers, jiubao circuit to give you an answer to the distinction between the tw
First of all, PCB, circuit boards are very familiar with, PCB (Printed Circuit Board), also known as printed circuit boards, is an important electronic component, is the electronic components of the support body, is the carrier of the electrical connection of electronic components. Because it is the use of electronic printing technology, it is known as the "printed" circuit board. pcb circuit board factory production, the main production is this board.
Electronic equipment using printed circuit boards, due to the consistency of similar printed circuit boards, thus avoiding the error of manual wiring, and can realize the automatic insertion or placement of electronic components, automatic soldering, automatic testing, to ensure the quality of electronic equipment, improve labor productivity, reduce costs, and easy maintenance.
PCBA is not just a circuit board, the full name of PCBA is assembly of PCB, in the circuit board printed out on the board, and then a variety of electronic devices through the surface packaging process assembly on the circuit board. Next is box assembly, is the assembly of PCB with the shell and other assembly, forming a finished product.
That is to say, the PCB empty board through the SMT on the piece, and then through the DIP plug-in the entire process, referred to as PCBA. this is a commonly used in the country a way to write, and in Europe and the United States, the standard writing is PCB 'A, is added with a slash. pcba, that is, paste the piece of pcb. in the customer needs multilayer circuit board manufacturer pcba, the SMT materials are generally Customer supplied.
The difference between PCB and PCBA is that pcb is a bare board, while pcba is a finished product. PCB is made of epoxy glass resin material and is divided into 4, 6, and 8 layer boards according to the number of signal layers, with 4 and 6 layer boards being the most common. After the circuit board manufacturer produces the bare board, chips and other SMD components are pasted on the PCB. PCBA may be understood as a finished circuit board, that is, the circuit board on the process are completed before the PCBA, that is, the PCB empty board through the SMT on the pieces, and then after the DIP plug-in the entire process, referred to as PCBA
Short for printed circuit board, usually in the insulating material, according to a predetermined design, made of printed lines, printed components or a combination of the two into a conductive pattern known as a printed circuit. And in the insulating substrate to provide electrical connections between components of the conductive pattern, known as the printed line. This makes the finished board of the printed circuit or printed line known as a printed circuit board, also known as a printed board or printed circuit board.
The standard PCB has no parts on the header and is often referred to as a "Printed Wiring Board (PWB)".
The above is the difference between PCB and PCBA, I believe that after reading, we must have a lot of understanding. Ltd. is a professional jiubao in multilayer PCB circuit board mass production of factories, factories have been producing more than 13 years, advanced technology, the default A-grade plate, the order of the whole process of personal follow-up, 22w + customer quality recognition.
