Down to the smallest detail: evaluations of selective soldering processes

When developing the best possible technical implementation of soldering tasks, the focus is on the product with its given design and any design adaptations that may still be required, the desired product quality, the existing and required automation concepts in production, and the process quality. Within the scope of the evaluation of the soldering process, these parameters are analyzed and discussed in detail with the customer in a design and product consultation, if they are not yet fixed.

Thus all processes are evaluated in order to achieve the goals required by the customers or to make them even more efficient through newly developed solutions. This ensures stable and efficient series production, with the desired quality of results. For the evaluation, task-specific masks, nozzles and workpiece carriers are produced, which replicate the subsequent original series process and also create initial conditions for subsequent validation samples. With that the entire process knowledge and years of experience are applied.

After receiving the customer’s inquiry, important information is already requested which is necessary for the subsequent evaluation. This clearly defines which goals are to be achieved with the finished production solution:

– Quantities/year
– Number and type of components
– Drawings, pictures and or samples of the assembly or joint parts to be soldered
– Cycle times, excluding handling times
– Cleanliness requirement of the component post process
– Cleanliness requirement during production
– Inline or batch production
– Pad geometries
– Surface conditions of the partners to be connected
– Possible flux specification
– Possible solder alloy specification

Much of this information about the product and the production are important parameters to be able to select or develop the right soldering process and the right machine configuration. These solutions are specifically tailored to the manufacturing needs and therefore also to the information around the end product or have even been developed for the product.
