Slow reflow
Webb3 feb. 2009 · What makes it slow is that DOM changes can change the user interface of a page, and redrawing the page is an expensive operation. Too many DOM changes mean a lot of redrawing since each change must be applied sequentially and synchronously to ensure the correct end result. Webb2 juni 2016 · A reflow profile with a slow ramp rate (<1°C/second) can aggravate the graping phenomena. For every degree the temperature increases, the viscosity of the flux decreases. A slow ramp rate allows more time for the solder flux to “run away” from the solder powder particles, forming a larger pool and spreading out at the base of the …

WebbSLOW FLOW AND NO-REFLOW IN ROTATIONAL ATHERECTOMY Rotational atherectomy is associated with a high rate of slow flow and no-reflow, with the incidence of no-reflow up to 16%. 76,77 The pathogenesis of this relates mainly to distal embolization of particulate debris generated during rotational atherectomy 76,77 but also to platelet activation ...
Webb23 juni 2024 · The different microstructures of each sample were created by controlling the cooling rate, fast or slow, during reflow. To characterize reliability, the samples endured thermal cycling − 40-125 °C until electrical failure. Finite element analysis was used to predict the primary deformation mechanism. WebbHEF4013BT - The HEF4013B is a dual D-type flip-flop with set and reset; positive-edge trigger. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VDD. Schmitt-trigger action on the clock input makes the circuit highly tolerant of slower clock rise and fall times.
