## 1 Introduction  
Production of electronic devices has seen a decrease in product life time as well as an increase in customization over the last decades [1]. The costs for new machines in micro assembly and packaging are harder to make up and increase the investment risks, especially for smaller enterprises [2]. This trend leads to a strong need for novel production methods and systems that are able to react fast and are flexible to changing customer needs without having to build complex new systems every time a new product is introduced [3]. To achieve this, a lot of work has been done in the field of flexible and reconfigurable manufacturing systems (RMS) [4; 5; 6]. There are different reconfigurable machines available in the market for highly customized micro manufacturing needs, e.g., the OurPlant-Series of Hacker Automation. Such RMS normally consist of a core machine that provides the basic functionality like an axis system for precise positioning in X and Y-direction as well as additional hardware modules with which the user can customize the system. Examples for such hardware modules would be grippers for the pick-and-place process or camera-systems for visual detection. Still, a lot of ideas for new products in this field get lost due to the uncertainty of whether a profitable production on a RMS is possible. RMS' tend to have higher acquisition costs. Therefore, to pay off their initial investment, one has to use them over more than one product. But with a volatile future, it is hard to predict which kind of products an enterprise will build in the next decades [7]. Decreasing investment risk can only be achieved by helping product designers and engineers to utilize their micro assembly RMS as effective as possible. For this, specialized tools are needed. With such tools, the conversion rate of product ideas to functioning products that can be built on a specific RMS is fostered, which is crucial for investment calculations. The goal of this paper is a new product development approach that aids product designers in developing products in the field of micro assembly in a way that suits their eventual production on RMS as best as possible. Such a method can overcome the need of higher utilization by integrating production knowledge into the development process. Therefore, this product development approach must be focused on the special needs of the micro assembly. As a crucial phase in development, its emphasis is the conceptual design phase, because decisions in conceptual design have the greatest impact on the finalized product. To achieve better results in this phase, customer integration is key. A lot of research has been done regarding product development. Section 2 of this paper investigates the most common and well-known approaches in this field. Different publications have discussed conceptual design as a part of the product development. [PERSON] et al. have established a morphological matrix tool for automated concept generation called MEMIC [8]. While they were able to generate new concepts for given tasks relatively quick, a case study with engineering students showed that the method was rather hard and uncomfortable to use. Different research groups targeted the improved sustainability of products during their conceptual design by using Life Cycle Assessment [9]. For this, they propose methods like a functional impact matrix that works as a visual tool [10] or a design repository [11]. [PERSON] and [PERSON] propose an engineering decision support system (EDSS) for a more sustainable component choice [12]. [PERSON] and [PERSON] did research on reducing the failure risk of a product by improving the conceptual design phase and introduced a risk in early design (RED) method for this [13]. Both the proposed improvements in sustainability as well as in failure risk depend on an enhanced choice of components in the conceptual design phase without integrating the customer or the production factors.
