The effect of pulse repetition rate on polymer ablation was studied experimentally and
theoretically for polyimide and 8230 photoresist, a polymethylmethacrylate (PMMA)-based polymer…

The nature of uv ablation of organic polymers is discussed in terms of a pseudo‐zeroth‐order
rate law of the form dx/dt = k 0 e −(E act /kT) , where E act is assumed to be the strength of …

A photothermal model of ablation is used to investigate the time scales for polymer degradation
by UV laser light. In the absence of a significant incubation effect, strong absorbers (eg, …

Ablation of strongly absorbing polymers, exemplified by polyimide, and weakly absorbing
polymers, exemplified by poly (methyl methacrylate), is discussed in terms of a photothermal …

In this study, an electromigration (EM) experiment of a ball in a flip chip package with
eutectic SnPb solder has been performed. The test vehicles had two types of ball grid array (BGA) …

A previous method for deciding if a set of time-to-fail data follows a lognormal distribution or
a Weibull distribution is expanded upon. Pearson's s-correlation coefficient is calculated for …

In this study, an Electromigration (EM) acceleration test was conducted at 150 oC ambient
temperature with 12A current. The solder joint was made of SAC305. Time 0 void evolution …

In this study, an accelerated Electromigration (EM) test was performed. The test vehicle has
four types of common interconnect structure. The first one is a classic Ball Grid Array (BGA), …

A qualitative molecular orbital exploration of the reaction path for CX2Y2-*· CY2+ X2 is
presented. The least-motion departure is symmetry forbidden and a less symmetrical path is …

The kinetics of transient liquid phase (TLP) solidification in Au-Sn layers electroplated on
Cu foil was investigated using differential scanning calorimetry (DSC). The solidification …
