Возникающие в процессе пайки пустоты существенно снижают как механическую, так и электрическую прочность соединения. Кроме того, существенно ухудшается теплопроводность, особенно в корпусах компонентов, где паяное соединение выполняет также роль теплоотвода. Предложены два новых подхода, ведущих к уменьшению образования пустот в паяных соединениях. Первый подход заключается в изменении шероховатости паяльной маски, влияющей на распределение флюса вокруг контактной площадки. Показано, что большая шероховатость паяльной маски положительно влияет на лучшую растекаемость флюса, выделяющегося при оплавлении припоя. При этом пятно флюса оказывается больше и он меньше попадает в паяное соединение, что приводит к минимизации объема и количества пустот. Второй подход заключается в нанесении не одного большого пятна паяльной пасты, а нескольких маленьких, разделенных небольшими промежутками. При этом для сохранения объема дозы припоя предложено использовать более толстые трафареты нанесения паяльной пасты. Наличие промежутков между пятнами паяльной пасты способствуют лучшему вытеснению газов, выделяющихся при оплавлении.</p></abstract><trans-abstract xml:lang="en"><p>The analysis of the causes of occurrence and ways of minimizing voids that are formed inside soldered joints is carried out. Voids that form during soldering signifi cantly reduce both the mechanical and electrical strength of the joint. In addition, thermal conductivity signifi cantly decreases, especially in component housings, where the soldered joint also acts as a heatsink.We propose two alternative approaches leading to a decrease in the formation of voids in soldered joints. The fi rst approach involves changing the roughness of the solder mask, which affects the distribution of fl uxaround the contact pad. Research shows that a higher roughness of the solder mask positively affects the better spreading of the fl ux released during solder refl ow. Here, the fl ux spot is larger and less of it gets into thesolde red joint, which leads to a minimization of the volume and number of voids. The second approach includes applying not one large amount of solder paste, but several small ones, separated by small gaps. Moreover, to maintain the volume of the solder dose, it is proposed to use thicker stencilsto apply solder paste. The presence of gaps between the spots of solder paste contributes to better displacement of gases released during refl ow.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>надежность радиоэлектронных средств</kwd><kwd>монтаж электронных компонентов</kwd><kwd>пустоты в паяных соединениях</kwd><kwd>флюс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reliability of radio-electronic equipment</kwd><kwd>installation of electronic components</kwd><kwd>voids in solder joints</kwd><kwd>fl ux</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена в рамках функционирования дизайн-центра «Силовая электро- ника» ФГБОУ ВО «Воронежский государственный технический университет»</funding-statement><funding-statement xml:lang="en">the work is carried out alongside the Educational Design Center for Electronics “Silovaya elektronika” at the Voronezh State Technical University</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Steiner F., Wirth V., Hirman M.
