N-Methyl-2-pyrrolidone (NMP) is an organic compound consisting of a 5-membered lactam. It is a colorless liquid, although impure samples can appear yellow. It is miscible with water and with most common organic solvents. It also belongs to the class of dipolar aprotic solvents such as dimethylformamide and dimethyl sulfoxide.
After parts have been in service in the engine, noticeable amounts of damage and wear will be observed. Provided that the damage and wear are within thresholds set by the design authority, it is possible that the blisks can be repaired. Repair of blisk components is complex and first requires an accurate 3D representation of the component.
In 2017, Cascade Microtech, together with Imec, developed a fully-automatic system to pre-bond test advanced 3D chips. The two companies won the 2017 National Instruments Engineering Impact Award in the electronics and semiconductor division for their development in which they titled "Probing of Large-Array, Fine-Pitch Microbumps for 3D ICs".
QBlade is especially adequate for teaching, as it provides a ’hands-on’ feeling for Horizontal-axis wind turbine (HAWT) rotor design and shows all the fundamental relationships between blade twist, blade chord, section airfoil performance, turbine control, power and load curves in an easy and intuitive way. QBlade also includes post ...

MOSCOW (Reuters) -Russia said on Wednesday that relations with Washington were so confrontational that Russian citizens should not visit the United States, Canada and some EU countries in coming ...
There are several methods for 3D IC design, including recrystallization and wafer bonding methods. There are two major types of wafer bonding, Cu-Cu connections (copper-to-copper connections between stacked ICs, used in TSVs) [18] [19] and through-silicon via (TSV). 3D ICs with TSVs may use solder microbumps, small solder balls as an interface between two individual dies in a 3D IC.
