Responding to Carbon Neutrality Trend, iST and DEKRA iSTLaunch LTS Platform Together

Responding to carbon neutrality trend, the major brands have begun to set carbon emission targets in recent years, and required the downstream supply chain to reduce carbonemission jointlyin order to meet the issue of environmental sustainability. To assist customers in achieving carbon reduction targets, iST and DEKRAiSTtoday (Nov. 16, 2021) announced thelaunch of LTS, low temperature soldering verification platform together. Recently, iST and DEKRAiSThave received requests one after another from the major technology brands, system assembly plants, PCB manufacturers, and CPU&GPU chip companies for whether they can perform the LTS verification test. The current industry chain from upstream to downstream have already been activated and the introduction of LTS has become a necessary step. The LTS technology is expected to grow substantially in 2022. That the reason why it is necessary for companies to accelerate their adoption.

In the pursuit of carbon neutrality, several global brands including Microsoft, Google and Apple havenot only set clearcarbon neutrality targets in recent years,but have planned to reduce net carbon emissionsto zero from all business, production supply chains and product life cycles. Because of the close interconnectivity of the semiconductor industry chain, global brands’ actions will influence every link of the supply chain. The suppliers who do not comply withsuch demands will most likely lose orders. Therefore, carbon reductions have transformed from an additional action into a necessary matter for corporate survival.

iSTmentioned, the International Standards Organization has also already stipulated standards for carbon reduction, including ISO 14064 for organizations, ISO 14067 for products and ISO 50001 for energy management. The main purpose of these standardsis to help corporations set energy reduction performance, and the easier method that provides significant results is to change the assembly process.

Most of the current assembly processes on the market arelead-free (Pb-free) soldering, whichrequireshigher melting temperature (217 to 220℃) to complete assembly. However, the high temperature leads to high energy consumption and can deform the PCB and large components (thisdeformationis known in the industry as “Warpage”).

To cope with this issue, manufacturers are thinking of lowering process temperatures,Therefore, due to the combination of this need and the aforementioned energy saving trend, Low Temperature Soldering (LTS) technology leapt into the market.

In the iNEMI report, although products using LTS currently account for less than 1%, by 2027, the market share of LTS will reach 20% due to the push for environmental protection in various industries.

DEKRA iSTmentioned, there are twomain driving forces for companies to introduce LTS. The first one is the aforementioned carbon reduction trend.The low temperature of LTS can improve energy savings in the manufacturing process by 40%.The second one is the improvement of yield and product reliability during the manufacturing process. The high temperature currently required by lead-free (Pb-free) solder pastes may cause cracks in motherboards or breaks in IC circuits during the manufacturing process,which will affect the lifespan of products. The low temperature characteristic of LTS can solve these problems.

However, for many companies, LTS is still a new technology. Both component-level and system-level companies are still unfamiliar with the technology and market regulations. Therefore, iST and DEKRA iST have jointly introduced LTS verification platforms to help Taiwanese companies accelerate their adoption of LTS by providing LTS testing and verification services for different links in the industry chain, such as components, board levels, and motherboards.

iST and DEKRA iST own the largest reliability assurance laboratory in Taiwan. With extensive production capabilities and experience, iST currently leads the world in the reliability verification of components and board levels. DEKRA iST is also one of the leaders in the industry for system verification and testing technologies. iST and DEKRA iSTprovide professional and objective reports from a third party perspective using their years of experience to implement the ESG goal of energy conservation and carbon reduction for corporations.
