The size of chip resistors and multilayer ceramic chip capacitors mounted on smartphone circuit boards is mainly 0402 (0.4 x 0.2 mm), but with the introduction of the 0201 (0.25 x 0.125 mm) size in 2019, further miniaturization is expected.<\/p>\n<p>However, as the size of the components decreases, the withstand voltage of the components is also reduced, making them more susceptible to damage.

However, the static electricity generated by the removal of the cover tape can cause components to stick to the tape or pop out of the pocket, resulting in a pickup error due to the missing component.<\/p>\n<p>While unmounted components will be detected in a following inspection, it causes additional work and inspections, which means that a pick-and-place error directly affects productivity.<\/p>\n<p>The graph below shows the relation between the number of pick-and-place errors and the humidity in a surface mount facility, recorded every day for a month. The scale on the left shows the relative humidity level and it clearly indicates that on the days the humidity falls below 40% there is a drastically higher rate of pick-and-place errors. In other words, with appropriate humidity control productivity can be increased by preventing ESD damage and pick-and-place errors.<\/p>\n<figure id=\"attachment_5617\" aria-describedby=\"caption-attachment-5617\" style=\"width: 675px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2024\/03\/electronic-aa-smt20513-article-11.jpg\" alt=\"\" width=\"675\" height=\"500\" class=\"size-full wp-image-5617\" srcset=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2024\/03\/electronic-aa-smt20513-article-11.jpg 675w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2024\/03\/electronic-aa-smt20513-article-11-300x222.jpg 300w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2024\/03\/electronic-aa-smt20513-article-11-524x388.jpg 524w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2024\/03\/electronic-aa-smt20513-article-11-456x338.jpg 456w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2024\/03\/electronic-aa-smt20513-article-11-220x163.jpg 220w\" sizes=\"(max-width: 675px) 100vw, 675px\" \/><figcaption id=\"caption-attachment-5617\" class=\"wp-caption-text\">Electronics, Surface Mount, Humidification<\/figcaption><\/figure>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-3573\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2023\/10\/electronic-aa-smt20513-article-12.jpeg\" alt=\"\" width=\"1100\" height=\"668\" srcset=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2023\/10\/electronic-aa-smt20513-article-12.jpeg 1100w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2023\/10\/electronic-aa-smt20513-article-12-300x182.jpeg 300w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2023\/10\/electronic-aa-smt20513-article-12-1024x622.jpeg 1024w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2023\/10\/electronic-aa-smt20513-article-12-768x466.jpeg 768w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2023\/10\/electronic-aa-smt20513-article-12-639x388.jpeg 639w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2023\/10\/electronic-aa-smt20513-article-12-540x328.jpeg 540w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2023\/10\/electronic-aa-smt20513-article-12-220x134.jpeg 220w\" sizes=\"(max-width: 1100px) 100vw, 1100px\" \/><\/p>\n<div style=\"max-width:1100px;text-align:center;margin: 4rem auto 8rem\">\n<div>\n<a style=\"margin-bottom:1rem;justify-content: center;align-items: center;padding: 1.5rem 6rem;color: #fff;font-weight: 500;font-size:1.2rem;float: left;margin-left:10px;width:auto;background: linear-gradient(20deg, rgba(31,207,158,1) 0%, rgba(27,217,168,1) 35%, rgba(19,222,173,1) 100%);border-radius: 3px\" href=\"https:\/\/www.dry-fog.com\/en\/documents\/report\/\" target=\"_blank\" rel=\"noopener\">View All Papers<\/a>\n<\/div>\n<div>\n<a style=\"margin-bottom:1rem;justify-content: center;align-items: center;padding: 1.5rem 9rem;color: #fff;font-weight: 500;font-size:1.2rem;float: left;margin-left:10px;width:auto;background: linear-gradient(20deg, rgba(31,207,158,1) 0%, rgba(27,217,168,1) 35%, rgba(19,222,173,1) 100%);border-radius: 3px\" href=\"https:\/\/www.dry-fog.com\/en\/contact\/\" target=\"_blank\" rel=\"noopener\">Contact Us<\/a>\n<\/div>\n<\/div>\n<div style=\"clear:both\"><\/div>\n<h3 id=\"link_8\" class=\"section-title\">Summary | 7 benefits of Dry Fog Humidification in SMT processes<\/h3>\n<p>Controlling humidity in SMT processes provides seven benefits. Among all the methods to control humidity, the Dry Fog Humidification system from IKEUCHI is the only one able to achieve all of these benefits.<\/p>\n<p><span style=\"color: #009966\">1.
