The reliability of reflow soldering by hot air reflow
Proceedings. Seventh IEEE/CHMT International Electronic Manufacturing Technology Symposium, 2003The reliability of a solder joint produced on an FR-4 substrate by hot air reflow soldering in SMT (surface mount technology) was investigated. The hot air reflow method is shown to make the temperature of the mounted components and substrate equal to the ambient temperature and does not greatly damage components.

The no-reflow phenomenon is associated with significant cardiac consequences: poor functional recovery, ongoing or recurrent ischaemia, and increased short-term mortality. It occurs rarely in elective percutaneous interventions, but far more frequently in patients who present with acute myocardial infarction (AMI).

Pathophysiology of the no-reflow phenomenon
Acute Cardiac Care, 2009The no-reflow phenomenon occurs in about one third of the patients treated with primary PCI for acute ST segment elevation myocardial infarction. Our understanding of its pathophysiology has expanded considerably: in addition of the effect of prolonged ischaemia also reperfusion injury contributes significantly to the microvascular damage in the ...

State of the Art: No-Reflow Phenomenon.
Cardiology clinics, 2020Primary percutaneous coronary intervention is the preferred reperfusion strategy for the management of acute ST-segment elevation myocardial infarction. No reflow is characterized by the inadequate myocardial perfusion of a given segment without angiographic evidence of persistent mechanical obstruction of epicardial vessels.

No-reflow describes a condition in which myocardial blood flow is reduced after a coronary intervention, despite angiographically patent coronary arteries. It is diagnosed by reduced epicardial blood flow in the presence of a seemingly patent coronary artery, however its incidence is thought to be higher than is estimated by clinical judgment or ...

Despite outstanding achievements in the last decades in the treatment of coronary artery disease and especially acute myocardial infarction, mortality and morbidity on follow-up have remained high. High morbidity is partly a result of the no-reflow phenomenon, which is the inability to reperfuse a previously ischemic region despite achieved patency of ...

A 53-year-old man presented to the emergency room with an acute inferolateral myocardial infarction (MI) of 2 hours duration. Urgent coronary angiography showed minor obstructive disease in the left coronary system and a 100% thrombotic occlusion in the mid segment of a large right coronary artery (Figure 8-1A).

The no-reflow phenomenon following a severe ischemic episode was first described in the brain [1] and subsequently has been observed in other organs including the kidney [2] and the heart [3]. In the brain edema and increased intracranial pressure inside of the rigid skull have been shown to limit reflow.
