(MENAFN- Khaleej Times)The latest chapter in the miniaturisation of increasingly smart consumer electronics lies in the hands of chip packagers an indispensable group of firms whose role in the supply chain alone is worth $27 billion.
Packagers like Taiwan's Advanced Semiconductor Engineering or ASE receive chips from manufacturers and prepare them for device assemblers by for instance encasing them in metal and resin. The advent of wearable devices particularly Apple's Watch and its dozens of chips pushed packagers to devise innovative ways of cramming ever-more communications graphics and location chips into the tiniest of spaces. To serve this market which researcher IDC expects to grow 173 per cent to $17.1 billion in 2015 ASE and rivals like Taiwan's Siliconware Precision Industries and Amkor Technology of the United States have come up with an assembly process known as System-in-Package or SiP. "SiP bundles a tonne of components into one simple plug-n-play almost like a Lego block" said Taipei-based semiconductor analyst Randy Abrams at Credit Suisse. In SiP the packager finds the optimal arrangement for multiple chips akin to solving a three-dimensional jigsaw. The tightly-packed formation allows for easier communication between chips yielding quicker more energy-efficient devices. "The SiP inside the Apple Watch was unprecedented" vice-president Jim Morrison of analysis firm Chipworks told Reuters. Chipworks found as many as 40 chips in the hermetically-sealed pod more than double any other package it had ever seen before. Internet of Things ASE aims to be a one-stop-shop for firms planning to stuff dozens of chips into wearables such as wristbands but also into home appliances and even light bulbs as more and more goods go online - a concept known as the Internet of Things or IoT. "We spent up to seven years developing the design" of SiP said ASE chief operating officer Tien Wu who targets riches promised by an IoT market IDC values at $1.7 trillion by 2020. ASE commands a leading 19 per cent of the packaging market. It supplies a large share of SiPs for the Apple Watch as well as for the fingerprint sensors in Apple's iPhones analysts said. It booked revenue growth of 19 per cent in January-June in part due to SiP and forecasts SiP business to double to 20 per cent of revenue in 2015. But with costs of SiP higher than those of conventional chip packaging profit margins may narrow. First-half net profit fell 5.1 per cent ASE said on Thursday. Analyst Carlos Peng at Fubon Securities said ASE's gross margin on the Apple Watch SiP is seven per cent to eight per cent lower than the firm's overall 20 per cent margin booked last year. "In an economy of scale it's still money-making" Peng said. But SiP is not the smallest solution. A costlier approach is System-on-Chip or SoC in which a single chip performs multiple functions. Though the technologically more complex SoCs are capable of fewer functions they could draw device makers away from SiPs if the cost of incorporating functions declines. Packagers may then lose out as the financial benefits of SoCs would go to SoC designers such as Qualcomm and MediaTek. For now however SiPs are cheaper and easier analysts said. "We're building a new business model" with SiP said ASE chief financial officer Joseph Tung. - Reuters
