Compensation of die warpage by capillary action
Proceedings of the 2011 34th International Spring Seminar on Electronics Technology (ISSE), 2011The stacking of dies for 3D-Packaging using TSVs is one of the most important developments in electronic packaging today. Dies for stacking are often very thin and therefore flexible. Hence, the mechanical stress in the deposited layers of the devices can cause a significant die warpage, which must be reduced during assembly.

VACUTEX™ capillary action dressing: a multicentre, randomized trial
British Journal of Nursing, 2001This article describes a preliminary study comparing the effect of VACUTEX™ capillary action wound dressing vs standard protocol for the treatment of sloughy and necrotic wounds. The study was carried out over a period of 5 months. Randomization was computer generated and batches of trial numbers and dressing allocation were delivered to each of the ...

Variably Elastic Hydrogel Patterned via Capillary Action in Microchannels
Langmuir, 2006Agarose hydrogels of varied elastic modulus can be patterned into 100-microm-wide channels with wall heights of 60 microm. After modifying the hydrogels with chloroacetic acid (acid gels), they are amenable to modification with amine-containing ligands using EDC-NHS chemistry.

Two Contrasting Theories of Capillary Action
American Journal of Physics, 1959Two theories regarding the mechanism of the rise of a liquid in a capillary tube appear in current textbooks of physics and physical chemistry. In one theory the rise is attributed to hydrostatic pressure; in the other, the liquid is drawn up the tube by a climbing meniscus. Evidence is presented in favor of the latter theory.

Principles around Accurate Blood Volume Collection Using Capillary Action
Langmuir, 2017Capillary action is one mechanism microfluidics uses to draw liquid autonomously in a substrate without the need of external energy. This behavior can be exploited to collect accurate volumes of liquids such as blood in narrow columns known as capillary tubes and help the development of inexpensive, user-friendly personalized biomedical tools ...
