As the world pays closer attention to energy conservation and environmental protection, LEDs can be seen almost everywhere from personal and household electronics to large billboards and traffic signals. Governments around the world have started off by issuing relevant policies, claiming to replace the conventional incandescent bulbs in their countries with LEDs, and this is expected to trigger new demand for LEDs. As the popularity of LED applications continues, automation equipment is needed to increase production efficiency and maintain product quality, so that performance, reliability, and cost could strike an optimal balance during the complicated manufacturing process.
Take LED die bonding process as an example. Individual die pieces should be attached on lead frames with conductive silver paste before they enter the manufacturing process including die bonding, sintering, wire bonding, epoxy coating, cutting, testing, and packaging. The dies are then packaged as different forms of LED, and according to market demand, they are assembled into a wide array of products in the end. During a manufacturing process as complicated as this, the key factor for the end products to reach a high-level quality lies in the machine vision and multiple-axis motion control, which are two functions provided by the die bonding machine.
When faced with the urge to increase production capacity, the old-fashioned architecture used by early LED manufacturing equipment was severely challenged by the need of real-time communication. Not only that, skewed LED legs also led the manufacturing systems to imprecise positioning problems, which could further result in low yield rate. To satisfy the desire for manufacturing efficiency and high quality, Advantech offers applications that combine multi-axis servo and stepping motors, making the die bonding process speedy and precise. In particular, our control cards offer multi-axis linear, circular, and continuous interpolation functions, which are exactly the keys to dealing with manufacturing processes that involve complex and precise movement control. In addition, Advantech provides optimal solutions that integrate industrial computers, image acquisition cards, servo motors, touch screens, image acquisition cameras, and relevant image computing software. These solutions not only satisfy various needs of micro assembly, but also enable our clients to produce high quality LED chips.
