Low Profile and Large Size WLCSP in IoT Applications

Abstract Recently, Wafer Level Chip Scale Package (WLCSP) Package is being rapidly adopted in Internet of Things (IoT) and consumer mobile electronics due to its low profile, small form factor and relatively easy assembly process. WLCSP with large die size becomes the trend in fulfilling high performance product demands. However, the solder joint reliability performances of WLCSP is the key challenge and becomes critical as increasing die size, especially the size is larger than 6 × 6 mm2. There is also growing interest in low profile WLCSP packages to less than 300 microns, especially when they are placed in a limited space inside IoT devices. Thin wafers are fragile and must be supported over their full dimensions to prevent cracking and breakage. An increasingly popular approach to thin wafer handling involves grinding and taping thin wafers with in-line machines. A specific carry tape have been also developed for transferring thin wafers after thinning. In this paper, WLCSP board level reliability for both large die size and low profile was studied, a test vehicle used for the large WLCSP package testing has 350um ball pitch and fully populated array. In addition to board level reliability test simulation and data collection, processing challenges were discussed, as well as processing solutions for thin wafer handling.

Inter-rater reliability of medication error classification in a voluntary patient safety incident reporting system HaiPro in Finland.

Medication errors are common in healthcare. Medication error reporting systems can be established for learning from medication errors and risk prone processes, and their data can be analysed and used for improving medication processes in healthcare organisations. However, data reliability testing is crucial to avoid biases in data interpretation and misleading findings informing patient safety improvement. To assess the inter-rater reliability of medication error classifications in a voluntary patient safety incident reporting system (HaiPro) widely used in Finland, and to explore reported medication errors and their contributing factors. The data consisted of medication errors (n = 32 592), including near misses, reported by 36 Finnish healthcare organisations in 2007-2009. The reliability of the original classifications was tested by an independent researcher reclassifying a random sample of errors (1%, n = 288) based on narratives. The inter-rater reliability of agreement (κ) of the classifications was calculated to describe the degree of conformity between the researcher and the original data classifiers. Descriptive statistics were used to describe the medication errors. The inter-rater reliability between the researcher and the original data classifiers was acceptable (κ ≥ 0.41) in 11 of 42 (26%) medication error classes. Thus, these errors could be pooled from different healthcare units for the exploration of medication errors at the level of all reporting organisations. Contributing factors were identified in 48% (n = 137) of the medication error narratives in the random sample (n = 288). The most commonly reported errors were dispensing errors (34%, n = 10 906), administration errors 25% (n = 7972), and documentation errors 17% (n = 5641). The data classified by different classifiers can be pooled for some of the medication error classes. Consistency of the classification and the quality of narratives need improvement, as well as reporting and classification of contributing factors to provide high quality information on medication errors.

Robust Reliability of Ceramic Capacitors for Power Electronics

Abstract For applications using Wide Band Gap (WBG) semiconductors, and for electronics for down-hole drilling, oil exploration, geothermal energy generation and power electronics, there is a growing need for capacitors that have robust reliability at temperatures of 125°C, 150°C or above. The development of more energy efficient power converters and inverters based on WBG semiconductors is driving the adoption of higher temperatures in a growing number of power electronics and automotive circuits since these operate at higher junction temperatures than traditional silicon. This has led to a growing need for high temperature capacitors with robust reliability. A Class-I C0G dielectric has been developed using Nickel electrodes for high temperature application up to 200°C and beyond. Since it is a paraelectric linear dielectric, these capacitors exhibit highly stable capacitance as a function of temperature and voltage, possess low loss (DF) and can conduct high RMS currents with a low temperature rise compared to other capacitor solutions. To maximize the capacitance density and achieve a high degree of mechanical robustness, stacks and leaded form factors are commonly needed. Materials for assembly of stacks are of interest due to the challenge of higher cost of attachment materials based on gold-solders or nano-silver pastes, as well as due to the presence of lead (Pb) in common high melting point (HMP) solders. This paper will report electrical properties and reliability test data on these Class-I C0G ceramic capacitors and stacks at high temperatures. It will also review thermal robustness and electrical characteristics of stacks assembled using Pb-free transient liquid phase sintering (TLPS) materials based on Sn-Cu and In-Ag.

Particle Filtering for Prognostics of a Newly Designed Product With a New Parameters Initialization Strategy Based on Reliability Test Data

In particle filtering-based prognostic methods, state and observation equations are used in which one or more parameters are uncertain. These parameters are estimated with collected monitoring data. The choices of the initial value ranges and distributions of the unknown parameters in the state and observation equations influence the performance of the particle filtering approaches, in terms of convergence, speed, and stability of prognostic results. For new products with little or even no degradation process data, uniform distributions over experience-based value ranges are the most common choice for parameters initialization. In this paper, the failure times’ data collected during reliability tests executed before volume production are used for defining the initial value ranges and distributions of uncertain parameters. This is expected to increase the convergence speed of the parameters estimation with monitored data and to reduce the uncertainty of the predicted remaining useful life. Numerical experiments on synthetic degradation processes of PEM fuel cells and lithium-ion batteries are considered. The convergence speed of the parameters estimation and the sensitivity of the proposed method to the duration and number of product samples in the reliability tests are analyzed. Comparisons with particle filtering methods with standard initialization are also carried out to verify the effectiveness of the proposed new strategy for parameters initialization.

Perceptions and Predictions of Service Quality-Customer Satisfaction of Conventional and Islamic Banks in the GCC Region

Abstract Purpose - The purpose of this paper is to investigate differences in the perceived relationship of service quality (SERVQUAL)-customer satisfaction between conventional and Islamic banks in the Gulf Council of Arab Countries (GCC) region which appears to be lacking such an investigation. Design/methodology/approach – The authors solicited survey responses from bank clients in all six countries of the region. They used data reliability tests followed by factor analysis to shortlist individual items of SERVQUAL to few manageable constructs. Nonparametric ranking tests were used to identify the importance constructs affecting customer satisfaction. A nonparametric multiple linear regression was employed to model causal effects. Findings - The results indicate that the two types of banks were associated with different SERVQUAL drivers as perceived by banks customers. Determinants, of overall satisfaction for the two types, also proved to be different. Research limitations/implications – Despite the important contribution of the paper to a region lacking a SERVQUAL comparative study on conventional versus Islamic banking, a similar investigation, with additional variables and more responses, at the global level would provide a better understanding of the subject. Practical implications – As firm value is associated with customer satisfaction, banks managers should, whether conventional or Islamic, pay attention to the details of each construct proved to be a predictor of customer satisfaction. Originality/value – The value of this research is in the wider geographical region comprising the highest number of Islamic banks and conventional in operation. It is also one of the few studies employing nonparametric multiple linear regression to model causal relationship in this area of research. Keywords: SERVQUAL, customer satisfaction, Islamic banking, GCC, nonparametric regression.

A combinatorial estimation approach for storage reliability with initial failures based on periodic testing data

ABSTRACTStorage reliability that measures the ability of products in a dormant state to keep their required functions is studied in this paper. Unlike the operational reliability, storage reliability for certain types of products may not be always 100% at the beginning of storage since there are existing possible initial failures that are normally neglected in the models of storage reliability. In this paper, a new combinatorial approach, the nonparametric measure for the estimates of the number of failed products and the current reliability at each testing time in storage, and the parametric measure for the estimates of the initial reliability and the failure rate based on the exponential reliability function, is proposed for estimating and predicting the storage reliability with possible initial failures. The proposed method has taken into consideration that the initial failure and the reliability testing data, before and during the storage process, are available for providing more accurate estimates of both initial failure probability and the probability of storage failures. When storage reliability prediction that is the main concern in this field should be made, the nonparametric estimates of failure numbers can be used into the parametric models for the failure process in storage. In the case of exponential models, the assessment and prediction method for storage reliability is provided in this paper. Finally, numerical examples are given to illustrate the method. Furthermore, a detailed comparison between the proposed method and the traditional method, for examining the rationality of assessment and prediction on the storage reliability, is presented. The results should be useful for planning a storage environment, decision-making concerning the maximum length of storage, and identifying the production quality.

An integrated approach to estimate storage reliability with initial failures based on E-Bayesian estimates

Storage reliability that measures the ability of products in a dormant state to keep their required functions is studied in this paper. For certain types of products, Storage reliability may not always be 100% at the beginning of storage, unlike the operational reliability, which exist possible initial failures that are normally neglected in the models of storage reliability. In this paper, a new integrated technique, the non-parametric measure based on the E-Bayesian estimates of current failure probabilities is combined with the parametric measure based on the exponential reliability function, is proposed to estimate and predict the storage reliability of products with possible initial failures, where the non-parametric method is used to estimate the number of failed products and the reliability at each testing time, and the parameter method is used to estimate the initial reliability and the failure rate of storage product. The proposed method has taken into consideration that, the reliability test data of storage products containing the unexamined before and during the storage process, is available for providing more accurate estimates of both the initial failure probability and the storage failure probability. When storage reliability prediction that is the main concern in this field should be made, the non-parametric estimates of failure numbers can be used into the parametric models for the failure process in storage. In the case of exponential models, the assessment and prediction method for storage reliability is presented in this paper. Finally, a numerical example is given to illustrate the method. Furthermore, a detailed comparison between the proposed and traditional method, for examining the rationality of assessment and prediction on the storage reliability, is investigated.

THE IMPACT OF THE QUALITY OF INTRINSIC AND EXTRINSIC ATTRIBUTES IN CREATING LOYALTY AND PURCHASE INTENTION

A business organization should always strive to maintain its sustainability by creating loyalty and purchase intention towards its products. The activity is specifically required for an organization engaged in the restaurant industry. The organization needs to be aware of which product attributes are in concern to the customers when purchasing the food in a restaurant. This research was intended to measure the importance of the quality from intrinsic and extrinsic attributes of a product for the customers and its impact on the customers’ loyalty and purchase intention. The research was conducted by involving the customers of a pizza product in Yogyakarta. 116 respondents were selected using convenience sampling technique. Meanwhile, the data being obtained were analyzed by using structural equation modeling (SEM) approach and data processing program named AMOS 20.0 after going through two stages of testing, namely data validity and data reliability tests. The results showed that the intrinsic attributes quality has a direct and positive impact on the customer’s purchase intention, but there is no impact on their loyalty. On the other hand, the extrinsic attributes quality has both direct and indirect impacts on the purchase intention through the loyalty mediator variable. The results also demonstrated the dominance of the importance of loyalty in the research model. This was indicated by the significance of direct impact or predictive total impact of loyalty towards purchase intention as compared to the impact of intrinsic and extrinsic attributes quality.
