What is PCBA and PCB’A ?
Jan 31, 2018

       PCBA is short for English Printed Circuit Board + Assembly, that is to say, the PCB is empty and passes through SMT, and then passes through the whole process of DIP plug-in, referred to as PCBA for short. This is a commonly used written PCB'A, is a plus point. This is called the official idiom. When we communicate or promote with foreign clients, they often ask PCBA what it means.


         Printed circuit board, also known as printed circuit board, printed circuit board, often used in English abbreviation PCB (Printed circuit board), is an important electronic components, is the support of electronic components, is the electronic components of the circuit connection provider. Because it is produced using electronic printing technology, it is called "printed" circuit board.

Before the advent of printed circuit boards, the interconnections between the electronic components were made up of complete wires by direct connection of the wires. Circuit breadboards now exist only as effective experimental tools, and printed circuit boards have assumed absolute dominance in the electronics industry. At the beginning of the 20th century, people began to study the method of replacing the wiring by printing in order to simplify the manufacture of electronic machines, reduce the wiring between electronic components, and reduce the manufacturing cost. Thirty years, there are constantly engineers proposed to be insulated metal substrate for wiring. And the most successful is that in 1925 Charles Ducas of the United States printed circuit patterns on insulated substrates and electroplating successfully established conductors for wiring. [1]

       Until 1936, the Austrian Paul Eisler published foil technology in the United Kingdom [1], he used a printed circuit board in a radio installation; and in Japan, Miyamoto helped spray the wiring Act " Act blowing method (Patent No. 119384)" successfully applied for a patent. [2] And both Paul Eisler's approach is most similar to today's printed circuit boards, a practice called subtraction that removes unwanted metals; and Charles Ducas, Miyamoto's approach is to add only The required wiring, known as addition. However, because of the large amount of heat generated by the electronic components at that time, the two substrates were difficult to co-operate with [1], so that there was no official practical application, but the printed circuit technology went one step further.
