Lenovo™ kondigt innovatief PC productieproces aan

Het nieuwe Low Temperature Solder (TLS) productieproces vermindert CO2-uitstoot met 35%

Dinsdag 7 februari 2017 — Lenovo kondigt vandaag een nieuwe patentaanvraag aan voor het zogenaamde Low Temperature Solder (LTS) proces. Dit bijzondere proces is ontwikkeld om de pc-productie te verbeteren door het besparen van energie en het vergroten van de betrouwbaarheid. Al meer dan tien jaar, na de stop op loodhoudende soldeersel, wordt er door de elektronica-industrie gezocht naar een oplossing voor het verminderen van warmte, stroomverbruik en CO2-uitstoot. Uiteindelijk is het op tin-gebaseerde soldeerproces verbeterd en het oudere loodhoudende proces vervangen.

Het nieuwe op tin-gebaseerde proces vereist extreem hoge temperaturen die meer energie verbruiken en de druk op componenten aanzienlijk verhogen. Met het nieuwe LTS-proces bewijst Lenovo dat het bedrijf voorop blijft lopen op het gebied van innovatie. De invoering van dit revolutionaire productieproces kan niet alleen worden toegepast op Lenovo-producten, maar is ook universeel toepasbaar op de productie van andere elektronische apparatuur.

Lenovo blijft zich bewijzen als een leider in innovatie, technologie en duurzaamheid. Haar inzet voor het ondersteunen van een overgang naar een C02-arme economie wordt verder aangetoond door de besparingen die het nieuwe LTS-proces met zich meebrengt. Bovendien is Lenovo van plan om de nieuwe procedure in 2018 op een industrie-brede basis gratis voor gebruik aan te bieden.

UK PRESS RELEASE

Lenovo™ Announces Breakthrough, Innovative PC Manufacturing Process

New Low Temperature Solder manufacturing process will reduce carbon emissions by 35%1

Estimated annual saving of 5,956 metric tons of CO2, equivalent to the consumption of 670,170 gallons of gasoline per year3

BEIJING and TOKYO – Feb 7, 2017Lenovo (HKSE: 992) (ADR: LNVGY) today announced a new patent-pending Low Temperature Solder (LTS) process developed to improve PC manufacturing by conserving energy and increasing reliability. Ever since having to abandon the use of lead-based solder more than 10 years ago due to environmental concerns, the electronics industry has been searching for a solution to reduce heat, power consumption and carbon emissions by improving the tin-based solder process which replaced the older lead-based process. The newer tin-based process required extremely high temperatures consuming more energy and adding significant stress on components. With a new LTS process, Lenovo proves it continues to be at the forefront of innovation, introducing a game-changing manufacturing process that is not only applicable to Lenovo products, but can be universally applied to all electronics manufacturing involving printed circuit boards with no cost or performance impact to customers.

The true innovation is in the science and testing required to develop and validate the new LTS process. Lenovo investigated thousands of combinations of solder paste material composed of a mixture of tin, copper, bismuth nickel and silver, specific compositions of flux material and unique profiles of time and heat temperatures that combine to enable this process.  As is typical in standard electronics assembly using surface mount technology (SMT), the solder and flux mixture is first printed on the face of the circuit board. The components are then added and heat is applied to melt the solder mixture, securing and connecting the components to the board.  With the new LTS process, soldering heat is applied at maximum temperatures of 180 degrees Celsius, a reduction of 70 degrees from the previous method. Throughout testing and validation, Lenovo used existing materials to compose the solder paste and existing oven equipment for heating, thus Lenovo can implement the new system without increasing production costs.  

After validation of the procedure, Lenovo discovered a significant reduction in carbon emissions as a result of using the new process. The procedure is already in production for ThinkPad E series and the 5th generation X1 Carbon recently announced at CES. Throughout 2017, Lenovo intends to implement the new LTS process on 8 SMT lines and estimates savings of up to 35% on carbon emissions1. By the end of 2018, Lenovo aims to have 33 SMT lines with 2 ovens per line using this new process, giving an estimated annual saving of 5,956 metric tons of CO22. To put this into perspective, the equivalent reduction in CO2 emissions is equal to the consumption of 670,170 gallons of gasoline3 per year.

Through the new process, Lenovo also expects better reliability for its devices due to lower heat stress during the “oven bake” procedure. In the early stages of deployment, Lenovo has observed a 50% decrease in printed circuit board warpage and a reduction in defective parts per million during the manufacturing process.

“By implementing the new LTS process, Lenovo is continuing to show its commitment to upholding sustainable business practices across its PC business,” said Luis Hernandez, vice president, Lenovo PC and Smart Devices Integrated Development Center. “Our focus on innovation extends beyond R&D and product design, to the way our products are manufactured. We are dedicated to advancing our business goals while reducing our impact on the environment and we’re proud this process achieves that.”

Lenovo continues to prove itself as a leader in innovation, technology and sustainability. Its commitment to supporting a transition to a lower carbon economy is further demonstrated by the savings the new LTS process brings. Furthermore, in 2018 Lenovo intends to offer the new procedure for use on an industry-wide basis free of charge.
