Are hand soldering and surface mount components prohibited!?
オオキ電子工業
The answer is NO. ~Omitted~ The background to this is that inexperienced workers without the correct basic knowledge of soldering perform manual soldering of surface mount components with a soldering iron, which can lead to damage to the components and product defects, often raising questions about responsibility. ~Omitted~ However, in reality, if the worker possesses the correct knowledge and skills, manual soldering of surface mount components is possible. According to the JAXA (Japan Aerospace Exploration Agency) standard for soldering processes for space surface mount components (ERG-0-043C 5.2.1), stable soldering is performed, and to avoid damage to the components, the principle is to adopt reflow methods or manual soldering. However, it is stated that manual 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, manual soldering by technicians is performed one point at a time. Therefore, it is correct to interpret that "manual soldering of surface mount components is prohibited for inexperienced workers." Excerpt from a blog by a soldering craftsman, June 16, 2017.
