Problems solved by technology

According to the PCBA software technical status in different states, due to the indistinguishable appearance, it is easy to make mistakes when marking, and there is a problem that the mark does not match the physical state, resulting in long production time, high production costs, and long and difficult after-sales maintenance; Different production equipment will also lead to a great increase in production costs, and it is also not convenient for centralized production

Abstract

The invention provides a novel PCBA state information indication method which is mainly used for distinguishing the product technical state of a PCBA. The method comprises the following steps that a,an output pin of an MCU is connected into a display unit; b, after the MCU is connected with a PCBA (Printed Circuit Board Assembly) to be detected, a power supply is switched on; c, the MCU outputs different control signals according to different curing software on the PCBA, and the control signals drive the display unit to work; and d, compared with the set product technical state of the PCBA according to the display condition of the display unit, the product technical state of the PCBA is obtained. The invention discloses a novel PCBA state information indication method. Technical personneland after-sales maintenance personnel can quickly judge the technical state of the PCBA by observing the flickering condition of the LED with naked eyes. Therefore, the time for classifying PCBAs canbe effectively reduced, centralized production of PCBAs is facilitated, the production time, cost and later after-sales maintenance are greatly saved, and meanwhile the problem that the identifiers are not consistent with the physical states is avoided.

Description

technical field [0001] The invention relates to the fields of fresh air purification air conditioners, fresh air purifiers, fan coil units, embedded control, circuit boards, and single-chip microcomputers, and more specifically relates to a novel PCBA state information indication method. Background technique [0002] As the generalization of products continues to increase, the same PCBA can already meet the hardware requirements of different products, and only needs to adjust the software according to the differentiated requirements of different products. According to the PCBA software technical status in different states, due to the indistinguishable appearance, it is easy to make mistakes when marking, and there is a problem that the mark does not match the physical state, resulting in long production time, high production costs, and long and difficult after-sales maintenance; Different production equipment will also greatly increase the production cost, and it is also not...
