Sustainable product design and the task of bringing new, earth friendly products to market is a top priority for corporate leaders in the manufacturing industry. By not reaching their compliance and sustainability goals, manufacturers risk loss of market share, fines for non-compliance against regulatory directives and possible damage to their brand. Managing material disclosure information from the supply chain is one of their biggest challenges.

Temperature measurement is one of the most important physical parameters when determining quality, accuracy and reliability of processes not only in industrial use, but also in almost all human activities. Temperature sensors are produced with different technologies to fit specific application requirements. IST AG has concentrated one part of the development and manufacturing on high-end thin-film temperature sensors. This know-how is partially derived from the semiconductor industry and allows us to manufacture sensors with high accuracy, excellent long-term stability, high reliability and repeatability within a wide temperature range from -200 °C up to 1000 °C. Because of very small dimensions and low thermal mass, the thin-film temperature sensors exhibit a very short response time.

The world of electronics continues to increase functional densities on products. One of the ways to increase density of a product is to utilize more of the 3 dimensional spaces available. Traditional printed circuit boards utilize the x/y plane and many miniaturization techniques apply to the x/y space savings, such as smaller components, finer pitches, and closer component to component distances.This paper will explore the evolution of 3D assembly techniques, starting from flexible circuit technology, cavity assembly, embedded technology, 3 dimensional surface mount assembly, etc.

Embedding components within the PC board structure is not a new concept. Until recently, however, most embedded component PC board applications adapted only passive elements. The early component forming processes relied on resistive inks and films to enable embedding of resistor and capacitors elements. Although these forming methods remain viable, many companies are choosing to place very thin discrete passive components and semiconductor die elements within the PC board layering structure. In addition to improving the products performance, companies have found that by reducing the component population on the PC board's surface, board level assembly is less complex and the PC board can be made smaller, The smaller substrate, even when more complex, often results in lower cost. Although size and cost reductions are significant attributes, the closer coupling of key elements can also contribute to improving functional performance.This paper focuses on six basic embedded component structure designs described in IPC-7092.

Proper assembly of components is critical in the manufacturing industry as it affects functionality and reliability. In a heat sink assembly, a detailed manual process is often utilized. However, an automated fixture is used whenever applicable.This paper will illustrate the use of strain gauge testing and Finite Element Analysis (FEA) as a simulation tool to evaluate and optimize the heat sink assembly process by manual and automated methods. Several PCBAs in the production line were subjected to the manual and automated assembly process. Strain gauge testing was performed and FEA models were built and run. Results were compared with the goal of improving the FEA model. The updated FEA model will be used in simulating different conditions in assembly. Proposed improvement solutions to some issues can also be verified through FEA.

Printed Circuit Boards (PCBs) and Printed Electronics (PE) both describe conductor/substrate combinations that make connections. Both PCB and PE technologies have been in use for a long time in one form or another with PCBs currently the standard for complex, high speed electronics and PE for user interface, complex form factor or other film based applications. New and innovative applications create the opportunity for promising structures. Taking advantage of the PCB shop's capability as well as the material set can help create these structures and indeed PE materials can find use in more traditional PCBs. New materials and new uses of existing materials open up many possibilities in electronic interconnecting structures. PCB manufacturers have a complex manufacturing infrastructure, well suited for both additive and subtractive conductor processing. While built around rigid material processing (flex PCB being the exception), there are opportunities for PE substrate processing. As electronics devices are applied to more and more parts of our lives, we need to continually push for better solutions. Fit, function, manufacturability, and cost are all important considerations. Crossing the PCB/PE boundary is a way to meet the challenge.

From consumer electronics to systems control, automotive technology to aviation and aerospace – today, electronics are absolutely essential in many sectors. They increasingly replace mechanical components, eliminating wear and tear and thereby extending the service life. What is easily forgotten in this regard is that electronics are also subject to the laws of mechanics. Mechanical test equipment is crucial to test components for the secure hold of welded, soldered or adhesive bonds. A new, mechanically intricate test probe with universal clamping jaws, that can even grasp the individual bonding wires, is in line with the trend toward ever smaller components. Serving as an actuator for these is a micro drive that can be precisely controlled using a miniaturised motion controller to relieve the control unit in the test device.
