In low-voltage plastic-encapsulated microcircuits, the heat may simply travel by conduction through the die attach and the die paddle for dissipation through the bottom of the package. In higher-voltage integrated circuit (IC) packages and in larger items such as insulated-gate bipolar transistor (IGBT) modules, a separate metal heat sink may be adhesively bonded to the package. The heat sink promotes conduction and prevents the temperature of the die from rising to a point where the circuitry on the die will fail. The bonding agent holding the heat sink in place may be solder, epoxy or another material. The heat sink is usually on the bottom of the component package, although some flip chips have a heat sink on the top side of the package. Note de contenu : - FIGURES : 1. Ultrasonic echoes from beneath this heat sink revealed numerous voids (white features) in the adhesive material - 2. Focused and gated on the die, ultrasound showed voids in the die attach in this IGBT module, as well as the acoustic shadows of numerous larger voids in the solder - 3. This image of a warped IGBT raft used ultrasound to report distance from the heat sink as color for the various regions of the heat sink and for the voids at various depths in the solder En ligne : http://www.adhesivesmag.com/articles/95524-nondestructive-inspection-for-heat-si [...] Format de la ressource électronique : Web Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=28752

SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).Index. décimale : 668.3 Adhésifs et produits semblables Résumé : According to Grand View Research, the global market for wearable medical devices is expected to reach $27.8 billion by 2022.1 Dow Corning reportedly sees the role of specialized adhesive technologies as a key driver of this growth, especially in skin- adhered medical devices, a major segment of the wearables market. Selecting the right adhesive for each device type based on factors such as duration of wear, skin condition, and device size and weight can have a significant impact on patient compliance and, ultimately, treatment efficacy. Advancements in silicone-based adhesive technologies are intended to offer expanded flexibility to support new device designs while meeting patient needs for comfort and ease of use.
"Wearable medical devices represent one of the fastest growing sectors in the healthcare industry, which is being fueled by several trends," said Marie Crane, Dow Corning’s Healthcare marketing leader. "While wearable monitoring and treatment devices can deliver important benefits to patients, caregivers and the health system as a whole, their effectiveness depends on compliant usage―and compliance is closely linked to comfort."Note de contenu : - MEDICAL DEVICE MEGA TRENDS : Population aging - Chronic conditions - Self-management - Cost control

Systèmes d'information -- GestionIndex. décimale : 658.05 Traitement de l'information dans l'entreprise Résumé : Why would a relatively small business choose to make the significant investment needed to implement an enterprise resource planning (ERP) system? There are many answers to that question, including streamlining engineering processes, improved inventory management, better costing knowledge, and more efficient financial reporting. This information is often extremely difficult to extract from legacy manual systems that rarely talk to each other.
Selecting the right ERP system is just the first step. Management commitment is needed for the software, training and implementation time required. The following shows how implementing an ERP system allowed Butler Automatic to reduce its lead times for building machines, as well as improve its financial reporting.Note de contenu : - Sélection d'un système
