Le choix de la p\u00e2te \u00e0 braser influence directement le processus d\u2019impression par pochoir. L\u2019alliage n\u2019est pas le seul facteur \u00e0 prendre en compte. Le type de poudre, la teneur en m\u00e9tal, la viscosit\u00e9, le tack et la stabilit\u00e9 de la p\u00e2te<\/strong> influencent \u00e9galement son comportement en production.<\/p>\n

La p\u00e2te \u00e0 braser doit donc \u00eatre adapt\u00e9e \u00e0 la fois \u00e0 la g\u00e9om\u00e9trie du pochoir et aux param\u00e8tres du processus.<\/p>\n

Le type de poudre doit \u00eatre adapt\u00e9 aux apertures<\/h2>\n

La p\u00e2te \u00e0 braser est compos\u00e9e d\u2019un m\u00e9lange de poudre de brasure et de flux<\/strong>. La poudre est disponible en diff\u00e9rentes granulom\u00e9tries, d\u00e9sign\u00e9es par des types.<\/p>\n

Pour l\u2019impression par pochoir, on retrouve notamment les types 3, 4 et 5<\/strong>. Plus le type est \u00e9lev\u00e9, plus les particules de brasure sont petites.<\/p>\n

Le choix d\u00e9pend notamment des dimensions des apertures du pochoir. Des ouvertures plus petites peuvent n\u00e9cessiter une poudre plus fine afin d\u2019obtenir un bon r\u00e9sultat d\u2019impression.<\/p>\n

Ce point est \u00e9galement li\u00e9 \u00e0 l\u2019area ratio<\/strong>. Lorsque les apertures deviennent plus petites par rapport \u00e0 l\u2019\u00e9paisseur du pochoir, un bon transfert de la p\u00e2te devient plus difficile. La combinaison entre la g\u00e9om\u00e9trie du pochoir et la p\u00e2te \u00e0 braser prend donc davantage d\u2019importance.<\/p>\n

Ne vous limitez pas au choix de l\u2019alliage<\/h2>\n

L\u2019alliage influence le comportement de fusion de la p\u00e2te \u00e0 braser, mais deux p\u00e2tes ne se comportent pas n\u00e9cessairement de la m\u00eame mani\u00e8re lors de l\u2019impression par pochoir.<\/p>\n

Des propri\u00e9t\u00e9s telles que la teneur en m\u00e9tal et la viscosit\u00e9<\/strong> influencent \u00e9galement le comportement pendant l\u2019impression.<\/p>\n

Le tack<\/strong>, ou pouvoir collant, est un autre facteur important. Apr\u00e8s le placement des composants dans la p\u00e2te imprim\u00e9e, celle-ci doit offrir une adh\u00e9rence suffisante pour les maintenir en position avant le processus de refusion.<\/p>\n

La p\u00e2te doit donc \u00eatre performante pendant l\u2019impression, mais \u00e9galement lors des \u00e9tapes suivantes du processus d\u2019assemblage.<\/p>\n

Une p\u00e2te stable contribue \u00e0 un processus stable<\/h2>\n

Pendant la production, la p\u00e2te \u00e0 braser reste un certain temps sur le pochoir. Il est donc important que ses propri\u00e9t\u00e9s restent suffisamment stables.<\/p>\n

Deux facteurs sont notamment \u00e0 prendre en compte : la stencil life<\/strong> et la print pause<\/strong>. Une interruption temporaire de la production ne doit pas rendre le comportement de la p\u00e2te impr\u00e9visible lors du red\u00e9marrage.<\/p>\n

La temp\u00e9rature, l\u2019humidit\u00e9 et le dess\u00e8chement peuvent \u00e9galement influencer le comportement de la p\u00e2te pendant son utilisation.<\/p>\n

Les performances d\u2019une p\u00e2te ne doivent donc pas \u00eatre \u00e9valu\u00e9es sur la base d\u2019une seule bonne impression. Sa stabilit\u00e9 tout au long du processus de production est \u00e9galement importante.<\/p>\n

Handling et pre-mixing<\/h2>\n

Une manipulation correcte commence par la mani\u00e8re dont la p\u00e2te \u00e0 braser est stock\u00e9e et pr\u00e9par\u00e9e avant la production.<\/p>\n

Le pre-mixing<\/strong> peut \u00e9galement faire partie de cette pr\u00e9paration. Il n\u2019existe toutefois pas de proc\u00e9dure universelle applicable \u00e0 toutes les p\u00e2tes \u00e0 braser.<\/p>\n

Le stockage, la pr\u00e9paration et le m\u00e9lange doivent donc \u00eatre adapt\u00e9s \u00e0 la p\u00e2te utilis\u00e9e et aux instructions correspondantes.<\/p>\n","protected":false},"featured_media":56598,"template":"","class_list":["post-56595","knowledgeportal","type-knowledgeportal","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"\nQuelle p\u00e2te \u00e0 braser choisir pour l\u2019impression par pochoir ?
