Description

technical field

[0001] The invention relates to the technical field of printed circuit boards, in particular to a printed circuit board and a method for manufacturing the printed circuit board. Background technique

[0002] Printed circuit boards are providers of electrical connections for electronic components. According to the number of layers of circuit boards, they can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer circuit boards. Since printed circuit boards are not general end products, Therefore, the definition of the name is slightly confusing. For example, the motherboard used for personal computers is called the motherboard, but not the circuit board directly. Although there are circuit boards in the motherboard, they are not the same. For another example: because there are integrated circuit parts loaded on the circuit board, the news media call it an IC board, but in fact it is not the same as a...
