NEOTech is excited to announce the recent implementation of an enhanced wire bonding manufacturing process for microelectronics circuit assemblies. This innovative process significantly increases production yields while reducing the production cycle time for each assembly. NEOTech remains committed to continuous improvements, particularly in the manufacturing of extraordinarily high-tech microelectronics products for the nation’s leading OEMs in the Aerospace & Defense, Medical Device, and Industrial markets. As part of this commitment, NEOTech has researched, tested, and qualified an advanced wire bonding technique known as Standoff Stitch (SOS), which further reinforces the company’s dedication to delivering high-quality, precision-driven solutions.
NEOTech, already recognized as an industry leader in SMT electronics manufacturing, stands at the forefront of high-tech microelectronics circuit assembly as well. The company’s original first-pass yields for wire bond and bond pull test processes were already excellent, achieving a 99.3% success rate. However, for mission-critical electronics used in aerospace, defense, space, and medical implantable device applications, even this high yield rate required further improvement. Common methods to enhance wire bond yield and reliability, such as the Burnishing process and the Security Bonding process, have been effective but significantly increase production time. To address this challenge, NEOTech has researched and implemented the SOS wire bond process, which not only boosts reliability but also reduces the production cycle time, offering a more efficient solution without compromising quality.
The SOS wire bond process is a superior method for ensuring high-quality interconnects of micro fine wires to the conductive pads on the substrate surface, which are often uneven or wavy due to the screen-printing process. When standard wire bonding methods are applied to these uneven surfaces, poor bond adherence can result, impacting overall quality. The SOS process addresses this issue by incorporating a gold ball approximately 2.5 mil in diameter during the first step of the wire bonding process. This gold ball accommodates the uneven surfaces without the need for additional steps, significantly reducing production time for each assembly. Furthermore, the increased surface area at the substrate bond interface created by the gold ball forms a more robust bond, enhancing reliability. NEOTech has seen remarkable improvements from this method, with production yields increasing to 99.99% and throughput doubling.
Jim Doyle, Chief Executive Officer of NEOTech’s Aerospace & Defense Business, expressed his enthusiasm for the recent advancements, stating, “At NEOTech, we are dedicated to fostering a culture of continuous improvement to ensure we consistently deliver the highest quality products to our customers. The implementation of the SOS wire bonding process is a testament to our commitment to innovation and operational excellence. By enhancing our wire bonding capabilities, we not only improve production efficiency but also ensure the reliability and performance of mission-critical microelectronics for the aerospace, defense, medical, and industrial sectors. We are proud of our team’s unwavering focus on quality and their efforts to push the boundaries of what’s possible in electronics manufacturing.”
