Factors governing heat affected zone during wire bonding
Transactions of Nonferrous Metals Society of China, 2009 In the wire bonding process of microelectronic packaging, heat affect zone (HAZ) is an important factor governing the loop profile of bonding. The height of loop is affected by the length of the HAZ. Factors governing the HAZ were studied. To investigate this relationship, experiments were done for various sizes of wire and free air ball (FAB ...

Advanced Engineering Materials, EarlyView.This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

Microstructural investigation of the heat-affected zone of simulated welded joint of P91 steel
Metalurgija, 2013 In the process of testing real components exposed to elevated temperature, it is not possible to neglect cracks. The most significant cracks can be induced by welding, which is applied for joining of structural components.
