Tokyo, Jan 10, 2013 - (ACN Newswire) - Tanaka Holdings Co., Ltd. (a company of Tanaka Precious Metals) today announced that Tanaka Denshi Kogyo K.K. of Tanaka Precious Metals, which boasts the world's leading share in the manufacture of bonding wire (wiring material, hereinafter "wire"), will commence the provision of samples of CA-1 copper wire with the reliability 1.5 times than conventional products and SEB silver wire with electrical conductivity improved by approximately 60% on January 11.
CA-1 and SEB are able to provide the necessary performance at a low cost as alternatives for gold wire that is currently used widely in semiconductor wiring not only in general purpose devices such as personal computers and smartphones, but also devices requiring high performance such as automotive electronics.
- CA-1 Bare Copper Bonding Wire
-- With the reliability 1.5 times than conventional products, this copper wire excels in all aspects of productivity, bondability, cost and electrical conductivity
CA-1 is bare copper wire with reliability improved to 1.5 times addressing the weaknesses of conventional bare copper wire. As a result of testing the failure rate at the high temperature of 175 degrees Celsius (when resistance increases 20%), it was found that while the failure rate of conventional bare copper wire started rising from 0% after 800 hours, CA-1 maintained a failure rate of 0% even after 1,200 hours, confirming that it has 1.5 times the reliability of conventional wire(*1).
Tanaka Denshi Kogyo mass produces both bare and precious metal-coated copper wire. Because the bare type is susceptible to oxidation, it presents issues such as low reliability and low productivity due to the narrow process window (tolerance range) that is a condition of stitch bonding (wire bonding to the substrates). Meanwhile, the precious metal-coated type presents issues such as tending to damage aluminum electrodes (resulting in low adhesion) due to the hardness of the ball (the round melted part at the tip of the wire) and being a more expensive type of copper wire. In order to resolve these issues, CA-1 was newly developed by creating an alloy under optimal conditions using 99.99% copper and a trace amount of metal, which realized the following features.
-- Reliability: 1.5 times the reliability of conventional bare type and achieve the same level as precious metal-coated wire
-- Productivity: Higher productivity due to the stitch bonding process window is approximately 1.5 times wider than conventional bare wire
-- Bondability: No damage to aluminum electrodes on IC (integrated circuit) chips due to the optimization of ball softness
-- Cost: Costs reduced by approximately 20% compared to precious metal-coated wire (*2)
With the current elevated gold prices, copper wire as an alternative to gold wire has begun to be widely used as wiring material for ICs and LSI (large-scale integration) circuits in general purpose devices such as personal computers and smartphones primarily from the perspective of reliability. In addition to these applications, CA-1 is able to significantly reduce manufacturing costs while sufficiently meeting the required performance by replacing the currently widely used gold wire in applications requiring high reliability, such as automotive electronics and industrial equipment.
- SEB Silver Bonding Wire
-- Electrical conductivity improved by approximately 60%, enabling costs to be reduced by 80% with almost equivalent performance as gold wire
SEB is a silver wire with electrical conductivity improved by approximately 60% compared to the existing SEA silver wire. Although SEA is able to reduce precious metals costs by approximately 80%(*3) compared to gold wire, and offers excellent bondability and productivity on par with gold wire, its weakness was having lower electrical conductivity (higher electrical resistance) than gold wire. In order to overcome this weakness, further improvements were made to the alloy combination that contributed to raising the electrical resistance. SEA's electrical resistance of approximately 5.2 micro ohm centimeters (microhm-cm) was improved to approximately 3.3 microhm-cm in SEB as a result, providing the world's first wire with the same level of electrical resistance as gold wire(*4). The features of SEB are as follows.
-- Electrical conductivity: Improved by approximately 60% compared to conventional products, which is
almost the same level as gold wire (improvement from SEA)
-- Cost: Precious metals costs can be reduced by approximately 80 % compared to gold wire
-- Bondability: No damage to aluminum electrodes due to the ball as soft as gold wire
-- Productivity: Sufficient adhesion achieved under almost the same usage conditions as gold wire
-- It is easy to switch from gold wire since it only requires safe and inexpensive nitrogen gas
The wiring material used in LEDs (light emitting diodes), ICs and LSIs is mainly gold wire, which offers excellent performance in all aspects such as electrical conductivity. SEA has mainly been used as an LED wiring material, but the improved electrical conductivity of SEB enables it to be used in ICs and LSIs of all types of electronic devices because it exhibits almost the same level of performance as gold wire at low cost.
Currently, in the bonding wire industry, gold is most widely used due to its excellent chemical properties, but gold is being replaced rapidly in areas where cheaper copper and silver can be used. Tanaka Denshi Kogyo will strengthen development of alternative materials that match customers' needs through samples provision of CA-1 and SEB that can substitute gold wire, and aims to begin mass production in the spring of 2013.
Tanaka Denshi Kogyo has scheduled to exhibit CA-1 and SEB at the 42nd Internepcon Japan, Asia's largest exhibition for electronics manufacturing and SMT, located at Tokyo Big Sight (Koto-ku, Tokyo) over three days from January 16 (Wed) until January 18 (Fri). Technical staff will constantly be on-site in the exhibit booth (East 24-26) to respond to interviews.

How do APIs and IoT relate? The answer is not as simple as merely adding an API on top of a dumb device, but rather about understanding the architectural patterns for implementing an IoT fabric. There are typically two or three trends: Exposing the device to a management framework Exposing that management framework to a business centric logic Exposing that business layer and data to end users. This last trend is the IoT stack, which involves a new shift in the separation of what stuff happens, where data lives and where the interface lies. For instance, it's a mix of architectural styles ...

The Domain Name Service (DNS) is one of the most important components in networking infrastructure, enabling users and services to access applications by translating URLs (names) into IP addresses (numbers). Because every icon and URL and all embedded content on a website requires a DNS lookup loading complex sites necessitates hundreds of DNS queries. In addition, as more internet-enabled ‘Things' get connected, people will rely on DNS to name and find their fridges, toasters and toilets. According to a recent IDG Research Services Survey this rate of traffic will only grow. What's driving t...

Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.

We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) i...
