Yield Enhancement and Yield Modeling for Mass Reflow Process of 0201 Components

Journal of Surface Mount Technology, 2004
ABSTRACT 0201 technology is becoming more popular in electronics manufacturing industry to produce high-density circuit boards. To enhance the 0201 assembly's manufacturability, some design/process parameters that may affect the 0201 assembly yield need to be thoroughly studied.

Ecological testing of different selective numbers of meadow clover in the Smolensk region

Аграрная наука Евро-Северо-Востока, 2018
Prospective selective material of the double-cut diploid meadow clover (Trifolium pratense L.) was tested. The aim of the research was to identify selective numbers mostly adapted to the ecological conditions of the Smolensk region. Six selective numbers

Quantifying the seasonal variations in grapevine yield components based on pre- and post-flowering weather conditions

OENO One, 2020
Seasonal differences in weather conditions cause marked variation in grapevine yield. However, quantitative relationships between various yield components and climatic factors at field scales are still lacking.

Nucleosynthetic yields of Z = 10⁻⁵ intermediate-mass stars [PDF]

Astronomy & Astrophysics, 2020
Context. Observed abundances of extremely metal-poor stars in the Galactic halo hold clues for understanding the ancient universe. Interpreting these clues requires theoretical stellar models in a wide range of masses in the low-metallicity regime. The existing literature is relatively rich with extremely metal-poor massive and low-mass stellar models.

The Torrefaction of Agricultural and Industrial Residues: Thermogravimetric Analysis, Characterization of the Products and TG-FTIR Analysis of the Gas Phase

Energies
Four biomass residues–rosemary pomace, rosemary cake, grape seed and apple pomace–were torrefied at 250, 350 and 450 °C, and the physical, chemical and structural changes were characterized.

The effect of a genetically improved common carp stock on the productivity of pond ecosystem: Implication for selective breeding in nature-close conditions

Aquaculture Reports
Aquaculture in Central Europe is mainly performed in man-made fishponds. Common carp (Cyprinus carpio), the main fish species, grows on natural food developing in fishponds and supplemental feeds (SF).
