Embodiment 1

[0062] The embodiment of the present invention provides a three-stage detection method for PCBA manufacturing, which is applied to a server, and the above server is equipped with a production control system;

[0063] Preferably, the above-mentioned production control system is an MES production system, and the MES system is equipped with a database, and the above-mentioned database is loaded with all reference data required in the detection process.

[0064] The core of the invention is to detect the PCBA production line and PCBA products according to the thinking before the production process, during the production process and after the production.

[0065] like figure 1 As shown, the steps of the above-mentioned three-stage detection method for PCBA manufacturing include: S101: Obtain the process parameters of the PCBA production line before the PCBA line is started;

[0066] Specifically, the process parameters of the above PCBA production line include the furnace temperat...

Embodiment 2

[0082] The embodiment of the present invention provides a possible implementation of real-time detection in the PCBA production process, combined with figure 1 and image 3 , the embodiment of the present invention includes the following steps:

[0083] After executing S103, the step to be executed is S301: during the PCBA production process, the process parameters of the PCBA production line and the PCBA product parameters are detected respectively;

[0084] It should be noted that the above steps of S301 include: real-time detection of the furnace temperature value of the PCBA production line, the humidity value of the PCBA production line, the pressure value of the PCBA production line, the thickness of the solder paste of the PCBA product, the area of ​​the solder paste of the PCBA product, and the volume of the solder paste of the PCBA product;

[0085] Conduct AOI testing, ICT testing and FCT testing on PCBA products;

[0086] Further, in actual production, PCBA produc...

Embodiment approach

[0104] like Figure 5 As shown, the embodiment of the present invention provides step S302 in step embodiment two: based on the detection results of PCBA production line process parameters and PCBA product detection results, it is possible to determine whether the PCBA production line process parameters and PCBA product parameters meet the second requirement implementation, the specific steps include:

[0105] S501: call PCBA production line process parameter reference data and PCBA product parameter reference data;

[0106] Specifically, the process parameters of the above PCBA production line include: the furnace temperature value of the PCBA production line, the humidity value of the PCBA production line, and the pressure value of the PCBA production line. The above PCBA product parameters include: PCBA product solder paste thickness, PCBA product solder paste area and PCBA product solder paste Volume, AOI yield, etc.;

[0107] After performing the step of S501, perform S...

Abstract

The invention provides a three-stage detection method and device for PCBA production, and relates to the technical field of PCBA detection. The method comprises the steps of acquiring a PCBA production line technological parameter before a PCBA production line is started; judging whether the PCBA production line technological parameter accords with a first requirement based on the PCBA productionline technological parameter; if yes, starting the PCBA production line; if no, stopping the PCBA production line. During a PCBA production process, the PCBA production line technological parameter and a PCBA product parameter are separately detected; and based on the detection result of the PCBA production line technological parameter and the detection result of the PCBA product, judging whetherthe PCBA production line technological parameter and the PCBA product parameter accord with a second requirement. By using the method and device provided by the invention, the PCBA product technological parameter during the production process can be monitored in real time, and thus the problem that in the prior art, the PCBA detection is low in degree of automation is relieved, and the PCBA product quality is improved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a PCBA detection method and device. Background technique [0002] In the prior art, manual analysis of key data of process parameters before, during and after production has the following problems: [0003] 1) Manual detection is used, which is inefficient; [0004] 2) Key parameters of PCBA products (such as solder paste thickness, solder paste area, etc.) cannot be tested, and the quality of PCBA products is prone to problems. [0005] 3) It is impossible to monitor the parameters in the production process in real time. Contents of the invention [0006] In view of this, the purpose of the present invention is to provide a three-stage detection method and device for PCBA manufacturing, to monitor the process parameters of PCBA products in the production process in real time, so as to alleviate the problem of low intelligence in PCBA detection in the prior art , and impro...
