Les circuits imprim\u00e9s souples, souvent appel\u00e9s FPC (Flexible Printed Circuit Boards) ou Circuits imprim\u00e9s flexibles<\/a>Les circuits imprim\u00e9s flexibles constituent une innovation majeure dans le domaine de l'assemblage et de la fabrication des circuits imprim\u00e9s et jouent un r\u00f4le tr\u00e8s important dans la fabrication des produits \u00e9lectroniques. Nos circuits imprim\u00e9s flexibles pr\u00e9sentent une excellente stabilit\u00e9 thermique, ce qui est essentiel pour les applications qui n\u00e9cessitent une attention particuli\u00e8re aux variations de temp\u00e9rature. Ils peuvent supporter une large gamme de temp\u00e9ratures sans affecter leurs performances \u00e9lectriques, m\u00eame dans des environnements extr\u00eamement froids ou \u00e0 haute temp\u00e9rature. Les PCB flexibles sont moins sujets aux d\u00e9faillances m\u00e9caniques, ils conviennent donc aux environnements difficiles et aux applications qui n\u00e9cessitent des d\u00e9placements fr\u00e9quents.<\/p>\n\n\n

Pr\u00e9cautions pour le placage des circuits imprim\u00e9s souples<\/h2>\n\n\n\n

1, Pr\u00e9traitement de placage FPC<\/strong>
Apr\u00e8s le processus de rev\u00eatement, la surface du conducteur en cuivre est sujette aux adh\u00e9sifs, \u00e0 la pollution par l'encre, et le processus \u00e0 haute temp\u00e9rature peut \u00e9galement d\u00e9clencher une d\u00e9coloration par oxydation. Afin d'obtenir un bon placage, il est n\u00e9cessaire d'\u00e9liminer ces polluants et la couche oxyd\u00e9e, et de nettoyer la surface du conducteur. Une partie des polluants et du conducteur en cuivre \u00e9tant \u00e9troitement li\u00e9s, il est difficile d'utiliser un produit de nettoyage doux, c'est pourquoi on utilise souvent une force sp\u00e9cifique d'abrasifs alcalins et un traitement de meulage \u00e0 la brosse. Le processus de nettoyage du pr\u00e9traitement a un impact significatif sur les caract\u00e9ristiques du FPC, les fabricants de PCB doivent contr\u00f4ler strictement ce lien pour que le processus de placage ult\u00e9rieur repose sur des bases solides.
2, Contr\u00f4le de l'\u00e9paisseur de la couche de placage FPC<\/strong>
Le processus de placage, la vitesse de d\u00e9p\u00f4t du m\u00e9tal et l'intensit\u00e9 du champ \u00e9lectrique sont \u00e9troitement li\u00e9s \u00e0 l'intensit\u00e9 du champ \u00e9lectrique par la forme du sch\u00e9ma du circuit et la relation entre la position de l'\u00e9lectrode. En g\u00e9n\u00e9ral, plus le fil est \u00e9troit, plus son extr\u00e9mit\u00e9 est pointue, plus il est proche de l'\u00e9lectrode, plus l'intensit\u00e9 du champ \u00e9lectrique est \u00e9lev\u00e9e, plus la partie correspondante de la couche de placage est \u00e9paisse. Pour r\u00e9pondre aux diverses exigences des produits \u00e9lectroniques en mati\u00e8re de performance des FPC.
3\u3001R\u00e9ponse aux taches de placage FPC<\/strong>
Le placage du PCB \u00e0 peine termin\u00e9 peut appara\u00eetre, la solution de rin\u00e7age de la surface n'est pas suffisante, la solution de placage r\u00e9siduelle, apr\u00e8s une p\u00e9riode de r\u00e9action chimique lente, la surface est sujette aux taches, \u00e0 la salet\u00e9 et \u00e0 la d\u00e9coloration, le FPC flexible en raison de la texture douce et in\u00e9gale, la solution est facile \u00e0 accumuler dans les d\u00e9pressions et r\u00e9agit \u00e0 la d\u00e9coloration, pour \u00e9viter cette situation, nous devons nous assurer que le processus de rin\u00e7age et de s\u00e9chage est ad\u00e9quat. La mise en \u0153uvre stricte des op\u00e9rations pertinentes dans le processus de production permet d'\u00e9viter les d\u00e9fauts de qualit\u00e9 des produits dus \u00e0 des probl\u00e8mes d'apparence, d'am\u00e9liorer la qualit\u00e9 globale de l'image du produit et de renforcer la comp\u00e9titivit\u00e9 du march\u00e9.
4, Nivellement \u00e0 l'air chaud du FPC<\/strong>
Le nivellement \u00e0 l'air chaud \u00e0 partir de la technologie de rev\u00eatement plomb-\u00e9tain des circuits imprim\u00e9s rigides, en raison de la simplicit\u00e9 de son utilisation dans le FPC, consiste \u00e0 plonger le circuit imprim\u00e9 verticalement dans le bain de plomb-\u00e9tain fondu apr\u00e8s que l'air chaud a souffl\u00e9 l'exc\u00e8s de soudure, mais les conditions du FPC sont difficiles. Si vous ne prenez pas de mesures, le FPC est difficile \u00e0 plonger dans la soudure, il doit \u00eatre pris en sandwich entre la plaque de maille en acier au titane et la surface doit \u00eatre pr\u00e9-nettoy\u00e9e et enduite de flux. En m\u00eame temps, le nivellement \u00e0 l'air chaud est facile \u00e0 r\u00e9aliser la soudure \u00e0 partir de l'extr\u00e9mit\u00e9 de la couche de couverture perc\u00e9e en dessous, en particulier dans la force d'adh\u00e9rence est faible lorsque plus fr\u00e9quemment. Le film polyimide absorbe facilement l'eau, et l'\u00e9vaporation de l'eau pendant le nivellement \u00e0 l'air chaud peut provoquer la formation de cloques et l'\u00e9caillage de la couche de recouvrement. Dans l'air chaud, l'aplanissement doit bien g\u00e9rer l'humidit\u00e9 de s\u00e9chage, suivre les sp\u00e9cifications d'exploitation pour assurer le bon d\u00e9roulement du processus, r\u00e9duire le taux de d\u00e9fectuosit\u00e9 du produit, r\u00e9duire beaucoup de bar, et am\u00e9liorer l'efficacit\u00e9 de la production.<\/p>\n\n\n
