Elaboration of the Production Process

The preceding phase of production process conceptualization (Section 8.1.2) produced the concept for the production process. Together with the data from product design (precision design of the interconnect device, circuit diagram) it provides the input variabie for subsequent eiaboration. The objective is to produce fuiiy eiaborated production processes and test procedures. The compatibility between product and production process is verified, and then the production concept of the interconnect device is eiaborated in more detail. This phase is closed by selection of the test procedures for quality assurance. These procedures are then integrated into the elaborated production process.

The product s properties emerge in increasing detail in the course of product elaboration (see design the 3D electronics). So the compatibility between product and the MID processes selected in the production concept and their feasibility can be rechecked with more precision before the production process chain has been elaborated. Typical questions include  

If there are no obstacles to manufacture of the MID, the MID production process is acceptable as selected. 

In order to ensure the quality required by the customer, the production expert works together with the mechanics and electronics developers to define the tests and test procedures. The following are the primary test criteria for MID (see Chapter 6)

As is the case with elaboration of the production process, prior to elaboration of the ACT process chain the compatibility between the detailed product and the assembly and connection technologies selected in the production concept is rechecked. For example, large, solid components act as heat sinks in the vapor phase and impair solderability. The product data are analyzed and compared with the solution concept for the production process. It is important to clarify the extent to which the choice of material and the design of the interconnect device and the components to be used are compatible with the selected assembly and connection technologies. The following are product properties that particularly require consideration in this context ...
