In BGAs, however, we cannot see the joints visually because they are hidden under the package, making X-ray a common inspection method.

As previously affirmed, the normal process to accomplish the reworking is to try to emulate the Reflow profile production for the individual component to be substituted [13]. Would you like to tell us about a lower price? Additionally, he is president of BeamWorks Inc.

This research could become a reference for future works inside of the organization. Amazon Advertising Find, attract, and engage customers.

Yin, Case Study Research: The assembly and welding of the component in the process of change of BGA were accomplished by a Station of Change ilc BGA operated 705 technicians of repairing area of the company. Processes of SMT assembly lines usually involve welding paste, placement of components and the operations of Reflow Welding [11].

Design and Assembly of BGAs and Voiding Requirements: IPC 7095 B

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: A characteristic model of recommended profile is described in the Figure 3 [12]: Analysis of the quality of the welding process in the exchange of component of BGA technology. Before proceeding with our next revision to IPCwe will conduct a survey, and you can help shape the next revision. 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 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 Reflow Process is a part of the process of Surface Mount Technology SMTtechnology where the components are mounted directly on the surface of the printed circuit board [10].

Results of the survey will help organize the amendment being discussed for IPC B. A comparative study”, Applied Soft Computing vol.

IPC C Design and Assembly Process Implementation for BGAs: IPC: : Books

Definition of Research Opportunity The use of components of BGA technology needs that companies carry out a complete monitoring of the process to assure the welding quality.

The cross section test was carried out in a certified laboratory of national recognition and the data of the tests were tabulated as well as the photographic images of the component obtained through electronic microscopy. If you are a seller for this product, would you like to suggest updates through seller support?

The organization in study makes the change of this component type frequently, without a diagnosis of the quality level of the welding developed in this process.

The critical issue of black pad associated with electroless immersion nickel gold ENIG has been described in detail. East Dane Designer Men’s Fashion. One of the unintentional consequences of this migration is that the industry had to request new methods for the welding of components in the boards; this comes in one moment in which the industry of semiconductors is developing components continually smaller and accommodating higher functionalities [5].

Withoutabox Submit to Film Festivals. Kendall, “A survey of surface mount device placement machine optimisation: IPC is using a tool called SurveyMonkey. 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.

Printing of Welding Paste, procedure of welding paste application, assembly of the component Place Component and welding in a re-fusion furnace.

Welding joins breakage is one of the main failure manners due to an inadequate lead-free reflow welding process [20]. The Reflow welding process consists of heating up the whole mounted board to liquefy the solder paste to form welding unions between SMDs and PCB without altering the original characteristics of v electric components.


When a BGA component change is going to be carried out, it is recognized that a process control is essential for obtaining an appropriate result. Amazon Drive Cloud storage from Amazon. The consequence of the cost reduction and the quality improvement reflects directly on the profit, due to the fact that the company must keep the same product prices [3].

Amazon Inspire Digital Educational Resources. The values of cost offered in Table 2referring to the process of exchange of the component, evidence that the accomplishment of this activity also reduces the cost that the company would have in case that the company had to discard the PCI Ipx, due to the lack of quality in the welding process.

This research was developed according to the study of the process of welding in the change of components of BGA technology, evaluating the quality of the welding. Quality in the process, Reflow soldering, BGA component, ic section, cracks, voids.

Therefore, voids generally are not detected. There were considered data of involved costs regarding two sceneries: Many issues have become especially important due to the change in the alloys of the ball, the ball shape, and the attachment procedures.

Shopbop Designer Fashion Brands. The use of components of BGA technology needs that companies carry out a complete monitoring of the process to assure the welding quality. Implementing ball grid array BGA and fine-pitch ball grid array FBGA technology presents some unique challenges for design, assembly, inspection and repair opc.

In the cases ipv that the BGA component presents a defect, for the accomplishment ippc the change of the component, it is used a specific Station of Change of BGA, so that the placement of the component is more accurate.

These costs considering the exchange of the component are presented in Table Get to Know Us.
