Control PCBA

PCBA is the abbreviation of the English Printed Circuit Board Assembly, that is to say, PCB empty board after SMT on the piece, or after the DIP plug-in the entire process, referred to as PCBA . This is a common way of writing in China, and the standard way of writing in Europe and the United States is PCB'A, with the addition of "'", which is called the official idiom.

PCBA is the abbreviation of the English Printed Circuit Board Assembly, that is to say, PCB empty board after SMT on the piece, or after the DIP plug-in the entire process, referred to as PCBA . This is a common way of writing in China, and the standard way of writing in Europe and the United States is PCB'A, with the addition of "'", which is called the official idiom.

  Printed circuit board, also known as printed circuit board, printed circuit board, often using the English abbreviation PCB (Printed circuit board), is an important electronic component, is the support body of electronic components, is the provider of electronic components line connection. Because it is made using electronic printing technology, it is called a "printed" circuit board. Before the emergence of printed circuit boards, the interconnection between electronic components are relying on the direct connection of wires to form a complete line. In the early 20th century, in order to simplify the production of electronic machines, reduce the wiring between electronic parts, reduce production costs and other advantages, so people began to study the way to print instead of wiring method. During the past thirty years, engineers have been proposing to use metal conductors on insulated substrates for wiring. The most successful one was Charles Ducas in 1925, who printed the wiring pattern on the insulated substrate and then successfully built the conductor for wiring by plating. Until 1936, Austrian Paul Eisler (Paul Eisler) published the foil technology in the United Kingdom, he used the printed circuit board in a radio device; and in Japan, Miyamoto Kiyonosuke to spray attached wiring method "Metaricon method blown wiring method (Patent No. 119384)" successfully patent application. Paul Eisler's method is the most similar to today's printed circuit boards, and is called the subtraction method, which removes the unwanted metal, while Charles Ducas and Kinosuke Miyamoto's method is to add only the required wiring, called the addition method. Although this is the case, because the electronic parts at that time generated a lot of heat, the two substrates are also difficult to use, so there is no official practical work, but also to make the printed circuit technology further.
