Le COB ne peut \u00eatre d\u00e9crit que comme un produit interm\u00e9diaire entre les technologies actuelles. En outre, le CSP (chip scale package) devrait \u00eatre le processus interm\u00e9diaire entre le chip on board et le flip chip.<\/p><p>Le COB consiste \u00e0 transplanter les op\u00e9rations de c\u00e2blage et de capsule de CI encapsul\u00e9s sur le circuit imprim\u00e9. En d'autres termes, la puce nue initialement fix\u00e9e au cadre de fils est fix\u00e9e au PCB. En outre, nous avons chang\u00e9 les fils de la liaison au cadre de fil \u00e0 la plaquette de soudure plaqu\u00e9e or du PCB, puis nous avons utilis\u00e9 de la colle \u00e9poxy pour couvrir les plaquettes et les fils au lieu de l'emballage original du moule. Les puces sur circuit imprim\u00e9 permettent d'\u00e9conomiser le processus de fabrication du scellement et du marquage des circuits int\u00e9gr\u00e9s. Elle peut \u00e9galement r\u00e9duire le co\u00fbt de la gestion et de la broche de l'usine de scellement de CI, de sorte que son processus sera fondamentalement moins cher que le processus de conditionnement de CI.<\/p><p>Parce qu'elle \u00e9tait bon march\u00e9, la technologie des premi\u00e8res puces sur carte n'\u00e9tait g\u00e9n\u00e9ralement utilis\u00e9e que dans les appareils \u00e9lectroniques grand public de bas niveau qui \u00e9taient moins fiables, tels que les jouets, les calculatrices, les petits moniteurs et les horloges, parce qu'ils \u00e9taient si bon march\u00e9 que vous pouviez simplement les jeter et en acheter un nouveau. Par cons\u00e9quent, les premiers processus de fabrication de puces sur carte \u00e9taient principalement des OEM de type familial ouverts par les employ\u00e9s des usines de scellement de circuits int\u00e9gr\u00e9s. Le salon \u00e9tait l'usine, et il n'y avait aucun contr\u00f4le environnemental. On se trompait souvent en pensant que la qualit\u00e9 des puces sur carte \u00e9tait si peu fiable.<\/p><p>Mais avec les progr\u00e8s de l'\u00e9poque, il y a de plus en plus de grandes usines qui regardent sa petite taille, ainsi que la tendance des produits minces et courts, l'utilisation de la puce sur carte dans les derni\u00e8res ann\u00e9es a \u00e9t\u00e9 de plus en plus tendance r\u00e9pandue, tels que les t\u00e9l\u00e9phones mobiles, appareils photo et autres produits courts ont beaucoup de produits dans le processus de la puce sur carte.<\/p><p>La COB pr\u00e9sente un autre avantage qui fait que certains vendeurs y sont particuli\u00e8rement attach\u00e9s. En raison de la n\u00e9cessit\u00e9 d'une colle d'\u00e9tanch\u00e9it\u00e9, la puce commune sur carte scellera tous les connecteurs de fils externes dans de la r\u00e9sine \u00e9poxy, comme ceux qui aiment craquer les hackers de conception d'autres personnes peuvent avoir besoin de passer plus de temps \u00e0 craquer en raison de cette fonctionnalit\u00e9, r\u00e9alisant indirectement l'am\u00e9lioration du niveau de s\u00e9curit\u00e9 anti-terroriste.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7b248cda elementor-widget elementor-widget-heading\" data-id=\"7b248cda\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Les exigences en mati\u00e8re de conception de la puce sur carte pour le PCB\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4db37436 elementor-widget elementor-widget-text-editor\" data-id=\"4db37436\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><img decoding=\"async\" src=\"https:\/\/www.mainpcba.com\/wp-content\/uploads\/2022\/12\/The-design-requirement-of-COB-for-PCB.jpg\" alt=\"Exigences en mati\u00e8re de conception d&#039;un COB pour un PCB \" width=\"1000\" height=\"600\" \/><\/p><p>1.Because chip on board\u00a0does not have IC packaging lead-frame, but use PCB to replace it, so the PCB welding pad design is very important, and the surface treatment can only use electric gold plating or <span style=\"text-decoration: underline;\"><a href=\"https:\/\/www.mainpcba.com\/fr\/what-is-enig-and-how-to-understand-it\/\">ENIG(nickel dipped gold)<\/a><\/span>, otherwise the gold wire or aluminum wire, even the latest copper wire will not hit the problem.<\/p><p>Le traitement de surface fini de la carte PC doit \u00eatre le placage d'or \u00e9lectrique ou ENIG, et d'\u00eatre plus \u00e9pais que la carte PC g\u00e9n\u00e9rale couche de placage d'or, peut fournir l'\u00e9nergie requise par la liaison de la matrice, la formation de l'aluminium d'or ou d'or.<\/p><p>2.
