One issue that has received the greatest attention in this revision x the acceptance criterion for voids in BGAs. In the period from April 01 to May 31,the acquisition of data verified that the amount of this model of produced Notebooks reached the total of 16, PCI MB and BGAs were changed, corresponding to an index of 1.

IPCC: Design and Assembly Process Implementation for BGAs

It is worth noting that voids are not new to BGAs. Delimitation of the research The studies of welding quality have wide application in several components in the electronic area and two types of tests are more commonly used for evaluating the welding: This research was developed according to the process of change of components of BGA technology, and it had as objective to develop a study to diagnose the quality of the welding in this process.

The other area that needs to be revisited is design of land patterns for BGAs. Conclusions On the basis of the analysis of the results presented in Figure 5it is possible to affirm that the company could perform the exchange process of a BGA component, inserted in the process of manufacture of notebooks, without risk in the final quality of the product, because the study of cross-section carried out in the BGA demonstrated that the executed process of welding attend the criteria of acceptability of International Standards IPC-AE and IPCB, therefore, it can be concluded that there is quality in the welding process of the exchange of the component of BGA technology.

The BGA Technology is one of the most attractive and thoroughly used encapsulation option because of many benefits, as the reduction of coplanarity problems, reduction of the size, better electric and thermal performances ipd. The methods and techniques used were the qualitative-quantitative approach, conducted by the case study technique in the welding process of the BGA component by 709 cross section and X-ray and data analysis alignment, cracks and voids within the process.

This research could become a reference for future works inside of the organization. The intent is to provide useful and practical information to the industry. Would you like to tell us about a lower price? Nature of the Research This work can be classified as a descriptive research that uses the technique of the case study as collection and analysis of data tool, with an approach so much qualitative as quantitative; the method of the case study allows the researchers to keep the holistic and significant characteristics of the events of the real life [21].

This article aimed to conduct jpc analysis of the quality of the Reflow of soldering in exchange of component of BGA technology. The voids of the welded balls after the component exchange were verified using the X-ray.

Initially, it was analyzed a theoretical framework through scientific papers where it was identified that the cross section and X-Ray tests are broadly used for this study type. In BGAs, however, we cannot see the joints visually because they are hidden under the package, making X-ray a common inspection method.

There have been concerns raised in the industry, and it was highly recommended in IPC that solder mask-defined lands are undesirable 709 they impact reliability adversely. Design and Methods, 4 th ed. A comparative study”, Applied Soft Computing vol.

IPC-7095C: Design and Assembly Process Implementation for BGAs

The research is justified based on the need of a diagnosis of the welding process in the implantation phase, because the use of materials and processes exempt of lead, also conduces to new concerns with the quality [6], becoming this type of research indispensable for any organization that tries to offer to their customers a quality product, avoiding thus that the company assumes reliability risks of their products when offer them in the market.


The BGA component is 7905 example thoroughly used in printed circuit boards by a process of reflow welding, which is one of the critical items in Surface Mount Technology.

The costs involved for the company in the case of exchange of BGA components are referring to the manpower including the orders and replacement of the component. Kendall, “A survey of surface mount device placement machine optimisation: AmazonGlobal Ship Orders Internationally.

BGA is used in several types of components, among them, chipsets and memory chips. This article is delimited to the study of a component of BGA technology of mechanical position U22 in the PCI MB of a Notebook and the type of mechanical test that cc carried out is the Cross-section test that will show characteristics of the BGA’s located in the right corner, in the left corner and in the center of the component.

Get to Know Us. It is also necessary to verify the adaptation of the assembly components. From the identification of the BGA component for the analysis, a study to evaluate the welding of the component was carried out.

ComiXology Thousands of Digital Comics. The BGAs are developed as a viable solution for the demand of the industry and with this component type, the quality of the welded join became one of the more critical factors of the process [22]. Implementing ball grid array BGA and fine-pitch ball grid array FBGA technology presents some unique challenges for design, assembly, inspection and repair personnel.
