Cu wire is increasing in usage in semiconductors due to continuous package cost reduction. Raising bar for reliability requirements, especially customers in automotive industry, has posted numerous challenges for Cu wire in meeting stringent quality requirements. This study is triggered by customer to development Grade 0 temperature cycles (TC) reliability with lower cost. Current package is running...
Rapid change of technologies, coupled with increase in demand of quality and reliability, development speed is the top challenge to have market win for semiconductor industries. As semiconductor is moving towards copper wire bonding, failure associated with reliability is critical. While reliability results take time to wait for the cycles to complete in order to have next decision or improvement...
Background: Complete or incomplete isthmus conduction block (CB, ICB) is difficult to interpret without detailed multiple electrodes mapping along the tricuspid annulus and isthmus area. To date, a simple and powerful predictor of isthmus CB is lacking. We hypothesize that distal coronary sinus (DCS) is almost activated via CS orifice (OCS) during pacing from low right atrial posterolateral (RPL)...
Precise effects of antiarrhythmic drugs (AAD) on the human atrial flutter (AFL) circuit are unknown. We study the effects of propafenone (PRO) and amiodarone (AMI) on the right atrial isthmus (IS) and free wall (FW) in 24 patients (pts) with typical AFL (Group I) and 20 pts without AFL (Group II). A 20-pole Halo catheter was placed around the tricuspid anulus. Incremental pacing from the low lateral...
Three nomographs are presented, illustrating the transformation of velocities from one inertial reference frame to another which is moving in uniform translation with respect to the first. These charts can conveniently be used as teaching aids in the instruction of the special theory of relativity.
