The answer is NO. ~Omitted~ The background to this is that inexperienced workers without proper foundational knowledge of soldering perform hand soldering of surface mount components with a soldering iron, leading to component damage and product defects, which often raises questions about accountability. ~Omitted~ However, in reality, if the worker possesses the correct knowledge and skills, hand soldering of surface mount components is possible. According to the JAXA (Japan Aerospace Exploration Agency) standard for space surface mount soldering processes (ERG-0-043C 5.2.1), stable soldering is to be performed, and to avoid damage to components, reflow methods or hand soldering should be adopted in principle. However, it is stated that hand soldering has a significant impact from the skill level of the worker, so it must be performed by individuals who have passed certification under the education and training outlined in section 4.3. In fields such as space development, aviation, and defense, hand soldering by skilled technicians is performed one point at a time. Therefore, it is correct to interpret that "hand soldering of surface mount components by inexperienced workers is prohibited." Excerpt from the blog of a soldering craftsman, 2017.6.16.
