Abstract
Description
はんだ付け材料で作られた前記アンテナを提供するステップであって、前記アンテナは、少なくとも部分的に固形のホットメルト接着材で覆われている、前記アンテナを提供するステップと、
前記アンテナをその融点より高い温度に加熱ステップであって、前記アンテナの加熱部分とホットメルト接着材が溶ける、前記アンテナを加熱するステップと、
前記アンテナに接続するために、適した所定の位置に前記ICを配置するステップと、
前記ICと前記アンテナとの間の電気的接続が確立するように前記アンテナと前記ICとを一緒に押圧するステップと、
前記ホットメルト接着材と前記アンテナとが固化するように前記RFIDタグを冷却するステップであって、前記ICと前記アンテナと間のはんだ接合がなされて、前記ICと前記アンテナとの間の前記はんだ接合は前記ホットメルト接着材が被されている、前記冷却するステップと、を含むことを特徴とする。
前記アンテナは、はんだ付け材料で作られ、前記ICは、前記アンテナにはんだ付けされており、
前記ICと前記アンテナとは、固形のホットメルト接着材で被せられたはんだ接点で接続されていることを特徴とする。
適切なホットメルト接着材の例は、PO(ポリオレフィン・ベースのホットメルト接着材:polyolefin−based hot melt adhesive)とEVA(エチレン・ビニル・アセテート・ホットメルト接着材:Ethylene−vinyl acetate hot melt adhesive)である。ただし、当業者は、他の同様のHMAも使用できることを理解できるであろう。
・タグあたりの硬化時間が短い。
・接着材の塗布方法や設備が安価である。HMAは高速でコーティングまたは印刷されるが、ICPまたはACPは、洗練された高価で低速の装置を使用して投与または噴射される。
・低コストの材料の使用を可能にする。
・RFIDタグのコストの削減。
・より少ないプロセスステップ。
・ホットメルト接着材は、溶剤ベースの接着材に比べていくつかの利点がある。揮発性有機化合物が減少または排除され、乾燥または硬化工程が排除される。ホットメルト接着材は保存期間が長く、通常は特別な注意なしに廃棄できる。HMAは固化中に厚みを失うことはなく、溶剤ベースの接着材は、乾燥中に層厚の最大50から70%を失う可能性がある。さらに、HMAはより環境にやさしく、食品への直接的接触を間接的に受け入れることができる。
