Abstract

The embodiment of the invention discloses a PCB test-based processing technology and a PCB, and aims at solving the technical problems of test misjudgment and low test efficiency caused by a very small testable bonding pad and large test pin deformation or dimension location tolerance of an existing via. The PCB test-based processing technology comprises the steps of determining a via according to a preset PCB layout; carrying out leaking treatment on the via in the processed PCB; and printing solder paste on the via and taking the via as a test bonding pad.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a processing technology based on PCB testing and a PCB board. Background technique [0002] Printed circuit board {PCB circuit board}, also known as printed circuit board, is the provider of electrical connections for electronic components. Its development has a history of more than 100 years; its design is mainly layout design; the main advantage of using circuit boards is that it greatly reduces wiring and assembly errors, and improves automation and production labor rates. According to the number of layers of circuit boards, it can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer circuit boards. [0003] Since the printed circuit board is not a general terminal product, the definition of the name is slightly confusing. They are not the same, so when evaluating the industry, the two are related but cannot ...
