Maintaining consistent solder print quality<\/h3>\n<p>Humidity control is also essential when printing solder onto the circuit board using a metal stencil. Low humidity will cause solder to dry faster and clog the stencil openings, resulting in inadequate application of solder onto the board. This in turn has a significant impact on the reliability of solder joints.<\/p>\n<p>If the humidity is too high, solder will absorb moisture resulting in excessive solder application, causing defects such as solder bridges, which lead to short circuiting, or causing components to stand up (tombstone or Manhattan phenomenon) during reflow soldering, leading to open circuits.<\/p>\n<p>Appropriate humidity control helps maintain solder printing quality and product reliability. There are several methods to control humidity, but the use of this Dry Fog humidification system is very efficient due to its operating costs which will be described later.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-3609\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-01.jpeg\" alt=\"\" width=\"1100\" height=\"733\" srcset=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-01.jpeg 1100w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-01-300x200.jpeg 300w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-01-1024x682.jpeg 1024w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-01-768x512.jpeg 768w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-01-582x388.jpeg 582w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-01-507x338.jpeg 507w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-01-220x147.jpeg 220w\" sizes=\"(max-width: 1100px) 100vw, 1100px\" \/><\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-3610\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-02.jpeg\" alt=\"\" width=\"1100\" height=\"520\" srcset=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-02.jpeg 1100w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-02-300x142.jpeg 300w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-02-1024x484.jpeg 1024w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-02-768x363.jpeg 768w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-02-710x336.jpeg 710w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-02-540x255.jpeg 540w, https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2022\/05\/electronic-aa-smt20513-article-02-220x104.jpeg 220w\" sizes=\"(max-width: 1100px) 100vw, 1100px\" \/><\/p>\n<div id=\"4\" style=\"padding-top: 1rem;margin-top: -1rem\"><\/div>\n<h3 id=\"link_4\" class=\"section-title\">4.
