Effect of Leadframe Oxidation on the Reliability of a Quad Flat No-Lead Package
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study analyzed the reliability of two condition types of copper leadframe, namely, good and oxidized. Both types of leadframe were used in the fabricating process of a quad flat no-lead ...
Comparative Study of Phenolic-Based and Amine-Based Underfill Materials in Flip Chip Plastic Ball Grid Array Package
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Phenolic and amine epoxy systems are widely used as hardeners in underfill materials for flip chip packaging. A comparison was made between these two systems in order to evaluate the reliability ...
The Effects of Multiple Zincation Process on Aluminum Bond Pad Surface for Electroless Nickel Immersion Gold Deposition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports the effects of a multiple zincation process on the Al bond pad surface prior to electroless nickel immersion gold deposition. The study of multiple zincation comprises the ...
Surface Topographical Characterization of Gold Aluminide Compound for Thermosonic Ball Bonding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Relatively little information is available on the growth patterns of gold aluminide compound in accurate 3D measurement as compared with 2D images of the projected surface. A 3D surface imaging ...
