IPC APEX EXPO 2022 SHOW & TELL MAGAZINE using radiative energy transfer, and light is converted to heat through optical absorption. is process can be made selective by exploit- ing the high absorptivity of solder pastes rela- tive to most other printed circuit board (PCB) materials, or with the aid of shadow masks. e optical flash can be modulated digitally, with high temporal resolution, which enables highly customizable processing flows ranging from traditional to highly innovative. Photonic soldering is compatible with stan- dard high temperature lead-free solder alloys (e.g., SAC305) in combination with temper- ature-sensitive substrates (e.g., PET). e nonequilibrium nature of the heating process enables thermal isolation of active regions from temperature sensitive regions. e resulting flexibility in material selection gives designers significant freedom and new options in outlin- ing device architectures. Previous presentations of this technology focused on the quality of junctions formed through this process. is paper focuses on the unique features of the photonic soldering pro- cess, as they relate to production line design and operation. • "CFX Open-Source Hardware Initiative," by Naim Kapadia, Manufacturing Technology Centre. Presenter: Raj Takhar, Senior Subject Matter Expert, Assent Compliance This presentation supports the poten- tial integration of IPC standards to block- chains. We used IPC-2591 as an example about how to integrate a given IPC stan- dard to interact with a blockchain using the con- cept of defining a publicly accessible standard (PAS) to outline logical smart contracts, to auto- mate the request and collection of data contained within the IPC standard. The potential of using a blockchain, is automation of back-office requests and processing of data, which can be collected via public or private blockchains. The design intent was to present a logical way of requesting data, using a given IPC standard, which defines a PAS pertaining to logical smart contracts, which when expanded across the entire IPC series of standards enables real-time data on products being assem- bled, with the potential to capture ever increasing requirements for reporting hazardous chemicals, capturing uses and handling instruc- tions as well real-time LCA data points pertaining to resources (labour, energy, emission type data points). Future pre- dictions within the presentation highlight how a potential marketplace for data could evolve with multiple supply chain actors sharing data across blockchains, with data provisioned by manufacturers / third-party solution providers, in the future, where dependent on a company's risk level acceptance criteria, mul- tiple dimensions of reporting complexity and data validation may occur within a blockchain. Expand- ing the potential of existing IPC standards via block- chains is critical for the on-going success of these standards in the future. The most important advice to our audience is to ask the questions, "Why could it not work?" and "What are the potential advantages or disadvan- tages you see with such a proposal?" Get in touch with me. I'd like to evolve the concept over the com- ing months and report back in the future with an updated version of the document.
