Forced hot air helps distribute heat evenly and reduces thermal stress on components.<\/p>\r\n<\/li>\r\n<li>\r\n<p>If you use infrared heaters, watch for hot and cold spots. Move the board if needed to avoid uneven heating.<\/p>\r\n<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>Commercial reflow ovens use conveyor belts and multiple heat zones for perfect results. At home, you can achieve reliable solder joints with careful setup and attention to detail.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">Reflow A Circuit Board<\/h2>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Start the Reflow<\/h3>\r\n\r\n\r\n\r\n<p>You have prepared your board and set up your oven. Now you are ready to start the reflow process. Place your board in the center of the oven. Close the door gently to avoid moving any components. Set your oven to follow the <a href=\"https:\/\/www.chuxin-smt.com\/hr\/slug-an-in-depth-guide-to-the-reflow-profile\/\" target=\"_blank\" rel=\"noopener\">temperature profile for your solder paste<\/a>.<\/p>\r\n\r\n\r\n\r\n<p>Follow these steps to Reflow A Circuit Board:<\/p>\r\n\r\n\r\n\r\n<ol class=\"wp-block-list\">\r\n<li>\r\n<p><strong>Preheat<\/strong>: Raise the oven temperature to about 150\u202f\u00b0C. Hold this temperature for 60 seconds. This step helps remove moisture and prepares the board for soldering.<\/p>\r\n<\/li>\r\n<li>\r\n<p><strong>Zona natapanja<\/strong>: Increase the temperature slowly to between 150\u202f\u00b0C and 180\u202f\u00b0C. Keep the board in this range for <a href=\"https:\/\/www.allpcb.com\/ar-SA\/blog\/pcb-assembly\/mastering-the-reflow-soldering-temperature-profile-a-step-by-step-guide.html\" target=\"_blank\" rel=\"nofollow noopener\">60 do 120 sekundi<\/a>. This allows the solder paste to activate and spread. If you rush this step, you may get poor solder joints. If you stay too long, the flux may lose its effectiveness.<\/p>\r\n<\/li>\r\n<li>\r\n<p><strong>Zona refluksa<\/strong>: Raise the temperature to the peak (225\u2013255\u202f\u00b0C, depending on your solder paste). Hold this temperature for 30 to 90 seconds. Watch for the solder to melt and become shiny. This is the most important part of the process. Do not let the board stay at this temperature for too long. Too much time can damage your components.<\/p>\r\n<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\r\n<p>Tip: Use an oven thermometer to check the actual temperature inside your oven. Oven dials are often inaccurate.<\/p>\r\n<\/blockquote>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Monitor the Process<\/h3>\r\n\r\n\r\n\r\n<p>You need to watch your board closely during the reflow process. Look through the oven window if possible. You will see the solder paste change from a dull gray to a shiny, liquid state. This is a clear sign that the solder has melted and is forming good joints.<\/p>\r\n\r\n\r\n\r\n<p>To avoid problems, keep these points in mind:<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>\r\n<p>Make sure components do not move or float on the solder. <a href=\"https:\/\/www.circuitnet.com\/experts\/44477.html\" target=\"_blank\" rel=\"nofollow noopener\">Accurate placement<\/a> before reflow helps prevent shifting.<\/p>\r\n<\/li>\r\n<li>\r\n<p>Avoid opening the oven during reflow. Sudden changes in temperature or airflow can cause components to shift or create cold joints.<\/p>\r\n<\/li>\r\n<li>\r\n<p>Manage the oven\u2019s thermal profile. High convection rates can push small parts out of place. Use gentle heating and avoid strong fans.<\/p>\r\n<\/li>\r\n<li>\r\n<p>Check that the solder paste holds each component securely. If you see any parts moving, stop the process and fix the placement before trying again.<\/p>\r\n<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\r\n<p>Note: Careful monitoring helps you catch issues early. You can prevent overheating and avoid costly mistakes.<\/p>\r\n<\/blockquote>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Cooling Down<\/h3>\r\n\r\n\r\n\r\n<p>After the solder has melted and formed joints, you need to cool the board. Turn off the oven and open the door slightly. Let the board cool down slowly in the oven for a few minutes. This helps <a href=\"https:\/\/www.chuxin-smt.com\/hr\/reflow-soldering-cooling-system-importance-optimization\/\" target=\"_blank\" rel=\"noopener\">prevent thermal shock<\/a>, which can crack solder joints or damage components.<\/p>\r\n\r\n\r\n\r\n<p>Follow these steps for safe cooling:<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>\r\n<p>Do not move the board right away. Let it sit until the temperature drops below 100\u202f\u00b0C.<\/p>\r\n<\/li>\r\n<li>\r\n<p>Once the board is cool enough to touch, remove it from the oven using heat-resistant gloves.<\/p>\r\n<\/li>\r\n<li>\r\n<p>Place the board on a flat, heat-safe surface. Allow it to reach room temperature before handling or testing.<\/p>\r\n<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\r\n<p>Tip: Never use fans or cold air to speed up cooling.
