Ultra-thin Flip-Chip Assembly for Heterogenous and Hybrid Integration

Abstract Flip-chip packaging of thin-die, in fact any packaging of thin-die, is one of today’s most significant challenges for die handling. Despite the difficulties presented as the thickness of chips continues to decrease, the wide range of applications they have enabled across multiple industries has led to increasing interest, as evidenced by the growth in the cumulative total number of publications on thin silicon based electronics, including Ultra-Thin Chips (UTCs), thinning of Silicon-on-Insulator, and wafer thinning. Smart devices including labels, loggers, wearables, implantable medical, and IoT are in demand. A key area of difficulty in the packaging of thin chips comes from removing the individual chips from dicing tape due to the adhesive nature of the tape and die cracking and edge chipping characteristic of thin die. As the industry continues to embrace the benefits afforded by thin devices, two trends are being witnessed. Devices continue to grow larger in area and thinner in thickness. American Semiconductor’s automated production process for packaging and assembly of chips ≤35um in thickness will be presented. This includes details regarding needleless die eject, pick tip design for ultra-thin devices, ultra-thin flip-chip interconnects, thin-chip overcoat, process controls, and assembly on flexible circuit boards (FCB).

Autonomic computing in manufacturing process coordination in industry 4.0 context

Abstract Industry 4.0 is defined as a paradigm that integrates the latest technological inventions in Artificial Intelligence (AI), Communication, and Information technologies, among other domains. This integration is made to increase the levels of automation, efficiency, and productivity of production, in manufacturing and industrial processes. In particular, the actors of the production processes (Things, Data, People and Services) should autonomously be able to act and make decisions, to implement self-* properties, such as self-configuration, self-management, and self-healing. In that sense, the Industry 4.0 revolution introduces many new challenges and issues that need to be solved. Some of those challenges are related to the integration of the heterogeneous actors that carry out the manufacturing process's tasks. Moreover, it is crucial to determine how to permit the actors to self-manage the production processes. In this paper, we present a framework for the integration of autonomous processes based on the needs for coordination, cooperation, and collaboration. Notably, we define three autonomic cycles that allow the actors of manufacturing processes (Data, People, Things, and Services) to interoperate. These autonomic cycles can create a coordinated plan for self-configuration, self-optimization, and self-healing during the manufacturing process. In this way, the actors can be appropriately coordinated, oriented to autonomously manufacture Smart Products, detect failures, and recover from errors or failures, among other things.

Povećana sigurnost radnika primjenom kolaborativnih robota u proizvodnim procesima Industrije 4.0

SUMMARY: By applying Industry 4.0, modernization of the production processes in industry is achieved. However, the safety of workers must be a priority. Automation of production processes and raising it to a higher level can be achieved by employing collaborative robots working together with workers. The degree of safety measures guarantees that there are no work injuries. In using collaborative robots we exploit all the advantages that they possess over first-generation industrial robots. They work together with workers, workers work in a safe environment, robots take up less space, they are not physically separated from workers, they are easy to manipulate, they are cheaper, and are suitable for small and medium size companies. We have the possibility of introducing different levels of automation in the production process, i.e. we can partially automate the tasks where complete automation is too complex or not economical. The use of collaborative robots will grow in the future, since the goals of the fourth industrial revolution cannot be achieved without collaborative robots, in other words, without the "smart manufacturing process" or "smart factory".

It is shown that in the complex problem of permanent increase in the competitiveness of aircraft, a special role is played by the increasing use of polymer composite materials in aircraft structures of the transport category every year. An important role is played not only by the rational choice of structural and technological solutions of their units and assemblies, but also by the use of new composite materials to reduce the cost and production time of aircraft structures, which greatly contributes to the implementation of high flight technological and economic characteristics of competitive aircraft in the global market for sales and services. A review and analysis of the development of new composite materials and technologies for their processing into products, discussed at the annual international exhibition Sampe 2019. From an analysis of the results of the materials of the exhibition and conferences held within its framework, it follows that the global aviation industry is paying more and more attention to the study of structural thermoplastics and the development of new technological processes associated with these materials, in particular, welding. In the field of aircraft manufacturing, various companies and institutes are working to optimize and reduce the cost of production processes for parts from polymer composite materials, especially in the direction of autoclave-free production technologies. New developments of leading aircraft manufacturers, in particular AIRBUS, for the creation of large-sized responsible high-load structural elements of aircraft from polymer composite materials with a thermoplastic matrix are presented. Of particular note is 3D printing technology, which aircraft manufacturers have successfully begun to use for the manufacture of aircraft parts. It is noted that this technology allows not only to reduce the production cycle of manufacturing parts, but also significantly reduce the energy intensity of processes, which positively affects the cost of products. During a visit to the AIRBUS factory in Nantes, a high level of automation of production processes for manufacturing parts from polymer composite materials with a large number of laying, winding machines, CNC machines, robots was noted, which is due to a significant production program for the A350XWB and A400M aircraft with a high degree of automation of production processes, and also a very high level of safety and labor protection.

Automated GMP compliant production of [18F]AlF-NOTA-octreotide

BackgroundGallium-68 labeled synthetic somatostatin analogs for PET/CT imaging are the current gold standard for somatostatin receptor imaging in neuroendocrine tumor patients. Despite good imaging properties, their use in clinical practice is hampered by the low production levels of 68Ga eluted from a 68Ge/68Ga generator. In contrast, 18F-tracers can be produced in large quantities allowing centralized production and distribution to distant PET centers. [18F]AlF-NOTA-octreotide is a promising tracer that combines a straightforward Al18F-based production procedure with excellent in vivo pharmacokinetics and specific tumor uptake, demonstrated in SSTR2 positive tumor mice. However, advancing towards clinical studies with [18F]AlF-NOTA-octreotide requires the development of an efficient automated GMP production process and additional preclinical studies are necessary to further evaluate the in vivo properties of [18F]AlF-NOTA-octreotide. In this study, we present the automated GMP production of [18F]AlF-NOTA-octreotide on the Trasis AllinOne® radio-synthesizer platform and quality control of the drug product in accordance with GMP. Further, radiometabolite studies were performed and the pharmacokinetics and biodistribution of [18F]AlF-NOTA-octreotide were assessed in healthy rats using μPET/MR.ResultsThe production process of [18F]AlF-NOTA-octreotide has been validated by three validation production runs and the tracer was obtained with a final batch activity of 10.8 ± 1.3 GBq at end of synthesis with a radiochemical yield of 26.1 ± 3.6% (dc), high radiochemical purity and stability (96.3 ± 0.2% up to 6 h post synthesis) and an apparent molar activity of 160.5 ± 75.3 GBq/μmol. The total synthesis time was 40 ± 3 min. Further, the quality control was successfully implemented using validated analytical procedures. Finally, [18F]AlF-NOTA-octreotide showed high in vivo stability and favorable pharmacokinetics with high and specific accumulation in SSTR2-expressing organs in rats.ConclusionThis robust and automated production process provides high batch activity of [18F]AlF-NOTA-octreotide allowing centralized production and shipment of the compound to remote PET centers. Further, the production process and quality control developed for [18F]AlF-NOTA-octreotide is easily implementable in a clinical setting and the tracer is a potential clinical alternative for somatostatin directed 68Ga labeled peptides obviating the need for a 68Ge/68Ga-generator. Finally, the favorable in vivo properties of [18F]AlF-NOTA-octreotide in rats, with high and specific accumulation in SSTR2 expressing organs, supports clinical translation.
