Dans la m\u00e9thode de s\u00e9rigraphie, la r\u00e9sine de soudure est utilis\u00e9e dans l'encre de la r\u00e9sine de soudure. En raison des diff\u00e9rentes m\u00e9thodes de durcissement, l'encre \u00e0 base de r\u00e9sine de soudure pr\u00e9sente \u00e9galement deux types de s\u00e9chage \u00e0 chaud et de s\u00e9chage \u00e0 chaud, actuellement, l'encre \u00e0 base de r\u00e9sine de soudure est principalement s\u00e9ch\u00e9e \u00e0 chaud. Les graphiques de r\u00e9sistance \u00e0 la soudure sont \u00e9galement form\u00e9s par l'encre \u00e0 travers l'impression de fuite de l'\u00e9cran apr\u00e8s le durcissement, parce qu'il s'agit d'un rev\u00eatement permanent sur la carte de circuit imprim\u00e9, afin d'avoir d'excellentes propri\u00e9t\u00e9s \u00e9lectriques et physiques et m\u00e9caniques, mais aussi pour pouvoir r\u00e9sister \u00e0 260 \u2103 (les produits militaires doivent r\u00e9sister \u00e0 288 \u2103) \u00e0 haute temp\u00e9rature.<\/p>\n<p>L'oligom\u00e8re de l'encre de r\u00e9sistance \u00e0 la soudure UV choisit principalement une bonne r\u00e9sistance \u00e0 la chaleur, une bonne isolation, une bonne adh\u00e9rence avec la r\u00e9sine de cuivre, telle que le bisph\u00e9nol A - l'acrylate \u00e9poxy, l'acrylate \u00e9poxy ph\u00e9nolique et l'acrylate de polyur\u00e9thane, l'acrylate \u00e9poxy ph\u00e9nolique \u00e9tant actuellement couramment utilis\u00e9. Le diluant r\u00e9actif est un acrylate polyfonctionnel avec un ester d'hydroxyle monofonctionnel, le photo-initiateur est principalement utilis\u00e9 907 ou DETX. Le pigment pr\u00e9c\u00e9dent \u00e9tait principalement le vert de phtalocyanine, mais maintenant le pigment colorant a du noir, de l'or et d'autres options, et peut ajouter plus de charges, ce qui est b\u00e9n\u00e9fique pour am\u00e9liorer la r\u00e9sistance \u00e0 la chaleur et r\u00e9duire le r\u00e9tr\u00e9cissement du volume. Afin d'am\u00e9liorer l'adh\u00e9rence de l'encre et du cuivre, vous devez \u00e9galement ajouter un peu de promoteur d'adh\u00e9rence, tel que le m\u00e9thacrylate de phosphore mono- ou di-ester.<\/p>\n<p>Lors de la pr\u00e9paration des encres r\u00e9sistantes aux soudures UV, les photo-initiateurs doivent \u00eatre soigneusement s\u00e9lectionn\u00e9s. Outre le 907 et le DETX mentionn\u00e9s ci-dessus, les 784 et 369, largement r\u00e9pandus, conviennent \u00e0 ce syst\u00e8me.<\/p>\n<h2><strong><a
