Enhanced Stitch Bondability...

The use of 2N9 Alloyed Au wire is becoming popular for fine-pitch and ultra-fine pitch bonding. These wires consist of 99% Au purity with 1% Pd and are formulated with dopant to enhance the looping capability and ball bond reliability. However, these wires are generally harder and more prone to wire breakage and non-sticking problem during stitch bond formation resulting in higher yield loss during production, especially for leaded devices. The nature of the lead frame design with certain degree of bouncing effect during bonding further complicates the robustness of the bonding process. The challenge is to be able to improve the stitch bondability for 2N Alloyed Au wire. The Stitch Integrator capillary helps to improve the bonding performance as shown in the following application. Bonding Condition Features Improved stitch integration with the substrate with better ultrasonic energy transfer. Enhanced coupling effect between the capillary and the wire with better stitch bondability....

Bonding Tool...

The pressure to reduce the cost of products has indirectly instilled certain elements of inconsistency to the lead frame and substrate materials, which directly affect the bond reliability of the stitch bonds. Inconsistent lead frame and substrate quality often results in NSOL, short tail or low stitch pull readings during wire bond. Mo...
