This specification covers requirements and test methods for materials, dimensions and tolerances, pipe stiffness, crush resistance, impact resistance, hydrostatic burst resistance, and solvent cement for poly(vinyl chloride) plastic drain, waste, and vent pipe and fittings. The pipe and fittings covered are suitable f…
Through silicon via (TSV) technology has been widely applied in CMOS image sensors (CIS). This paper reports the wetting behavior of polymer liquid in the TSV insulation process by spin coating. The O2plasma treatment was used to increase the hydrophilicity of the substrate surface in order to reduce the adhesion betw…
The following topics are dealt with: GPU-based calculations in electromagnetic wave diffraction problems; quantum waveguides; electromagnetic wave diffraction; tensor permittivity reconstruction; multicomponent chromatography; nonlinear wave interactions; functionally graded elastic substructures; layered piezoelectri…
Plastics Engineering is the official publication of the Society of Plastics Engineers (SPE). We provide plastics professionals with a wealth of information about machinery, technological advances, materials innovations, sustainability, and more.
Structural impact is concerned to the behavior of mechanical structures subjected to large dynamic, impact or blast loadings, which induce inelastic structural deformations. In these cases, the material behavior is influenced by high strain rates so leading to erroneous predictions of the structural response if the st…
This guide covers high-strength low-alloy steel shapes of structural quality, produced by quenching and self-tempering process (QST). The chemical analysis of the heat and of the steel product analysis shall conform to the chemical requirements prescribed by the reference materials. The Charpy V-notch test shall be pe…
The long-term reliability of flip chip and boardlevel solder joint is significantly affected by the properties of the surface finish. Various surface finishes such as Immersion Sn, Immersion Ag, Organic solderability preservatives (OSP), Electrolytic Ni/Au (ENEG), and electroless Ni/immersion Au (ENIG) surface finish…
Cover Caption: The photograph shows the desulphurization of hot metal (30 kg) in an induction furnace through in situ generation of magnesium. The graphite reactor used for the generation of magnesium is seen introduced into the crucible containing the hot metal. The “insert” shows the graphite reactor drawn out of th…
Significance and Use 3.1 Most coating specifications specify the thickness of the coating because coating thickness is often an important factor in the performance of the coating in service. 3.2 The methods included in this guide are suitable for accepta
Special specimen was designed to study the morphology change of SnAgCu solder under the influence of electromigration (EM) alone. High current stressing was applied to the specimens so that EM of solder would happen at both room and high temperatures. The interfacial crack at cathode is the main failure mode, although…
UK-based PEM fuel cell developer Intelligent Energy has strengthened its long-standing US presence by establishing a commercial facility in San Jose, California. The company has also announced that its innovative Upp™ personal energy device has achieved IEC and ISO certification, which together allow the product to be…
The Affiliate Plan, established by the IEEE Board of Directors, enables individuals who are not members of the IEEE, but who have an interest in the field of plasma science, to join the IEEE Nuclear and Plasma Sciences Society. Admission as an affiliate requires only membership in a professional society listed. Affili…
A novel photochromic diarylethene based on a six-membered pyrimidine moiety 1-(2,4-dimethoxyl-5-pyrimidinyl)-2-[2-methyl-5-(4-n-pentylbenzene)-3-thienyl] perfluorocyclopent-ene has been synthesized. Its properties, including photochromic behavior and fluorescent properties, have been investigated. The compounds exhibi…
The influence of viscoelastic behavior of polybutylene terephthalate (PBT) on reliability of the thermal contact of a spotlight module is evaluated. The contact between a module and the heat sink is evaluated using non-linear finite element model. The viscoelastic behavior of PBT was obtained under multiple frequencie…
This specification covers electric-fusion-welded austenitic chromium-nickel stainless steel pipe suitable for corrosive or high-temperature service, or both, or for general applications. The pipes shall be sorted into five different classes. Class 1 pipes shall be double welded by processes employing filler metal in a…
Al2O3particles linked by graphene oxide sheets (GO-linked Al2O3), were fabricated via self-assembly leading by electrostatic attraction and incorporated into the glass fibers reinforced polymer composites (GFRPC) to improve their thermal conductivities. Flexible and ultrathin GO sheet was able to bridge adjacent Al2O3…

Significance and Use 5.1 The purpose of this specification is to establish a recognized criterion for “waterproofness” in terms of a minimum hydrostatic resistance. The necessary definitions to provide a common understanding of the meaning of this charact
The failure of solder joints on Cu-Fe-P lead frame of power MOSFETs was found after long term services. The microstructures of failed and accelerated experimental solder joints have been investigated in detail in order to find out the failure mechanism. SEM, TEM, EDS and EPMA techniques were used in this study. Observ…
Abstract DOCOL 1000 LCEZE high-strength steel has with a microstructure that contains ferrite, which is soft and contributes to good formability; and martensite, which is hard and contributes to the strength of the material. These steels are designed according to their lowest tensile strength. The ZE suffix denotes a…
