Hesse & Knipps, Inc., the Americas subsidiary of Hesse & Knipps Semiconductor Equipment GmbH, leading manufacturer of high speed fine pitch wedge bonders for the backend semiconductor industry, announces that it will present an IMAPS webinar, "Why Wedge Bond," taking place on November 10, 2011 from 12pm - 1pm. Webinar participants may register on-line. The cost is $25 for IMAPS members and $50 for non-members. This Webinar lecture is scheduled for 50 minutes of lecture followed by 10 minutes of Q&A.

In the past, ball bonding has dominated the interconnect market because of its high speed and capabilities. However, as interconnect density is becoming greater, ball bonding is reaching its limits. Thus, wedge bonding has the potential to dominate the market for bonding ultra fine-pitch devices.

Wire bonding is an ultrasonic welding process accomplished by deforming the wire and the substrate together, forming an alloy of the two. Wedge bonding, because it directly deforms the wire without first forming a ball, is capable of producing a bond with minimum deformation and extremely low loop heights. High quality wedge bonds can produce deformation just 20-25% larger than the wire diameter, whereas typical ball bonds are 1.8-2 times the wire diameter.

Why Wedge Bond webinar participants will come away with practical knowledge of the advantages of wedge bonding over ball bonding as a reliable alternative that is capable of handling future requirements for bonding thin packages and ultra-fine pitch devices.

In addition, the webinar will cover the latest wedge bonding equipment capabilities, including improved accuracy, stitch bond speeds approaching 10 wires/second, constant loop height and constant loop length algorithms for optimum control of electrical properties, low loop capability and real-time, process-integrated quality control that measures 6 critical bond process parameters for every bond, enabling quick preventive action and an exhaustive look into the wedge bond process.
