When SMD soldering prototypes, samples, and small production runs, the essential goal is to create reliable solder connections even in the first assembly. When selecting an appropriate soldering oven, the following points should be considered:

​

1. Optimal Heat Distribution: The key factor is optimal heat distribution. Convection reflow ovens, especially those used for prototypes, are often designed in a way that different temperatures can be measured in the working area. This can lead to unreliable soldering in some areas while soldering has already occurred in others. Infrared ovens exhibit this characteristic even more pronouncedly. In this regard, all vapor phase soldering systems score points due to their design.

2. Potential Intervention in the Soldering Process: Soldering programs should be adaptable, allowing for adjustments during the soldering process.

3. Reliable Reproduction of the Soldering Process: It should be ensured that the same soldering process can always be carried out to assess changes in the nature of the assembly.

4. Transferability of the Soldering Process to Mass Production: It may be necessary, or at least advantageous, to transfer the soldering results of prototypes or samples into mass production. Being able to generate a comparable soldering curve with similar technology can be a significant advantage, especially for complex assemblies and difficult-to-solder components. This ensures that a soldering quality already tested can be adopted in the production series, potentially avoiding errors at the start of production.

5. Service and Support: Tips, assistance with challenging projects, and advice are important even in prototype soldering. Having competent long-term contacts for service and support is crucial.
