Effect of reflow profile parameters on surface mount chip resistor solder joint shear strength [PDF]

, 2014
The focus of this study is on the effect of reflow parameters on the joint shear strength. Eight reflow profiles were developed using four factors at two levels of Taguchi design of experiment for 1206, 0805 and 0603 chip resistors.

Impact of Stress Hyperglycemia on No-Reflow Phenomenon in Patients with ST Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention

Global Heart, 2022
Background: Stress hyperglycemia is a common finding during acute myocardial infarction and associated with poor prognosis. To reduce the occurrence of no-reflow, prognostic factors must be identified before primary percutaneous coronary intervention ...

The relation between platelet/lymphocyte ratio and the occurrence of no reflow in patients with ST-segment elevation myocardial infarction managed by primary percutaneous coronary intervention

International Journal of the Cardiovascular Academy, 2021
Introduction: No reflow phenomenon following primary percutaneous coronary intervention (PCI) is a strong predictor of mortality. Platelet/lymphocyte ratio (PLR) is an indicator of long-term outcome in ischemic heart disease patients.

The Effect of Multiple Solder Reflows on the Formation of Cu₆Sn₅ Intermetallics and the Decomposition of SnAg3.0Cu0.5 Solder Joints in the Framework of Rework and Reuse of MLCC Components

Metals
A rework of electronic assemblies and the reuse of electronic components are the most effective ways to reduce electronic waste. Since neither components nor substrates were developed with the intention of multiple usage, the question of how the ...

Effect of chronic pretreatment with beta-blockers on no-reflow phenomenon in diabetic patients with acute ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention

The Egyptian Heart Journal, 2017
Background: No-reflow is an important factor as it predicts a poor outcome in patients undergoing primary angioplasty. In comparison with patients attaining TIMI 3 flow, patients with no-reflow have an increased incidence of ventricular arrhythmias ...
