Ordering the wrong one is one of the most expensive and common warehouse mistakes: the bag seems to do the job, the component gets damaged anyway, and the defect appears on the production line or in the field.<\/p><p>We handle all three, with stock in Mexico.<\/p>\n\n\n\n\n<h2 class=\"sbc-tam sbc-tam-h6\">The three bags that are called &quot;ESD&quot;\u00ab<\/h2>\n<p><strong>1. Antistatic (the pink one).<\/strong> Its only function is <strong>do not generate load<\/strong> It does not shield against external electrical discharge and does not stop moisture. It is suitable for wrapping, separating, and transporting within a controlled area, and for nothing else.<\/p><p>One detail that almost no one checks: formulations with <strong>amine<\/strong> They can corrode polycarbonate over time. If the component or its housing contains them, amine-free material must be requested.<\/p><p><strong>2. Static shielding (the metallized one).<\/strong> It has a layer of metallized polyester between dissipative layers, and that forms a <strong>Faraday cage<\/strong>The contents are protected from a discharge occurring outside the bag. This is the discharge required for the component to leave the ESD area.<\/p><p><strong>3. Moisture barrier (MBB).<\/strong> It&#039;s a laminate with a <strong>inner layer of aluminum<\/strong>, Not just metallic. This difference significantly reduces water vapor transmission, making it suitable for moisture-sensitive components. It also acts as a shield, thus fulfilling the previous function as well.<\/p><p>The industry benchmark for antistatic barrier material is <strong>MIL-PRF-81705 Type I<\/strong>, and that is the one that the bags require. <strong>IPC\/JEDEC J-STD-033<\/strong> for MSD component packaging.<\/p>\n\n\n\n\n<h2 class=\"sbc-tam sbc-tam-h6\">Which one do you get?<\/h2>\n<ul><li>The component <strong>does not leave the ESD area<\/strong> and you just have to separate it or wrap it \u2192 <strong>antistatic<\/strong>.<\/li><li>The component <strong>leaves the area<\/strong>, travels between plants or is stored outside \u2192 <strong>static shielding<\/strong>.<\/li><li>The component has <strong>declared MSL level<\/strong> \u2014semiconductors, integrated circuits, modules\u2014 or it will be stored for months \u2192 <strong>moisture barrier<\/strong>, sealed, with desiccant and indicator inside.<\/li><\/ul><p>If in doubt, the barrier option covers all three functions. It costs more per piece but less than an emergency baked batch.<\/p>\n\n\n\n\n\n\n\n<h2 class=\"sbc-tam sbc-tam-h6\">The bag alone offers no protection.<\/h2>\n<p>A sealed barrier bag with nothing inside only traps the humid air that was present at the time of sealing. The packaging of an MSD component consists of four things, and all four must be present:<\/p><ul><li><strong>The barrier bag<\/strong>, heat sealed.<\/li><li><strong><a href=\"https:\/\/sbcgroup.com.mx\/en\/disecantes\/\">Desiccant<\/a><\/strong>, dosed according to the area of the bag.

Without a date, the floor life cannot be calculated.<\/li><\/ul><p>If the indicator has already changed, the next step is <a href=\"https:\/\/sbcgroup.com.mx\/en\/horneado\/\">bake<\/a> before assembling.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n<h3 class=\"sbc-tam sbc-tam-h6 sbc-acento-oscuro\">ESD Annual Guide<\/h3>\n<p class=\"sbc-sobre-oscuro\">We published a guide that cross-references bag type, size, and application to resolve the selection without back-and-forth.<\/p>\n\n\n\n\n\n<h2 class=\"sbc-tam sbc-tam-h6\">How to seal and reopen it<\/h2>\n<ol><li>Insert component, desiccant and indicator, leaving room for sealing and for two reopenings.<\/li><li>Heat seal with a continuous strip. A seal with a fold is a leaky seal.<\/li><li>Label with MSL level and <strong>sealing date<\/strong>.<\/li><li>When opening, cut above the previous seal to preserve a useful length, and note the date: from that moment on, the floor is ready for use.<\/li><li>When resealed, use new desiccant and indicator.

The rose prevents generating a charge, but <strong>It doesn&#039;t impress<\/strong> It does not protect against an external discharge nor stop moisture. For the component to leave the ESD area, a shielding bag is required, and if it has an MSL level, a barrier bag is also necessary.<\/p><p><strong>What is the difference between metallized and barrier?<\/strong><br>The metallic shield; the barrier version also has an inner layer of aluminum that significantly reduces the passage of water vapor. The second type is necessary for moisture-sensitive components.<\/p><p><strong>How many desiccants are in each bag?<\/strong><br>It depends on the area of the bag, not the number of components. J-STD-033 specifies the dosage in desiccant units. Tell us the size and we&#039;ll tell you the dosage.<\/p><p><strong>Can they be reused?<\/strong><br>The bag is fine if the seal is cut at the top and the material is not punctured. The desiccant and indicator are not: they are replaced with each reseal.<\/p><p><strong>What measures are they using?<\/strong><br>Catalog sizes: 10x12, 10x20, 10x30 and 16x18 inches. Other sizes available upon request.<\/p><p><strong>Do they sell just the bag or the complete package?<\/strong><br>Both. You can buy the consumable or send us the component and receive it sealed with desiccant and indicator.<\/p>","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":413,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"pagelayer_contact_templates":[],"_pagelayer_content":"","footnotes":""},"class_list":["post-408","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/sbcgroup.com.mx\/en\/wp-json\/wp\/v2\/pages\/408","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sbcgroup.com.mx\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/sbcgroup.com.mx\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/sbcgroup.com.mx\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/sbcgroup.com.mx\/en\/wp-json\/wp\/v2\/comments?post=408"}],"version-history":[{"count":8,"href":"https:\/\/sbcgroup.com.mx\/en\/wp-json\/wp\/v2\/pages\/408\/revisions"}],"predecessor-version":[{"id":2546,"href":"https:\/\/sbcgroup.com.mx\/en\/wp-json\/wp\/v2\/pages\/408\/revisions\/2546"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/sbcgroup.com.mx\/en\/wp-json\/wp\/v2\/media\/413"}],"wp:attachment":[{"href":"https:\/\/sbcgroup.com.mx\/en\/wp-json\/wp\/v2\/media?parent=408"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
