Si vous cherchez à introduire une pièce d'équipement précieuse dans votre passe-temps de soudure ou votre profession, alors un nettoyeur à ultrasons pourrait être juste la chose. Les nettoyeurs à ultrasons ont aujourd'hui la capacité de nettoyer les cartes de circuits imprimés (PCB) sans faire les dommages qu'ils pouvaient autrefois. En effet, la plupart des nettoyeurs à ultrasons utilisent désormais des ondes modulantes et variables plutôt qu'une seule onde de mouvement intense et singulière. La variabilité fournit un environnement plus sûr pour les cartes et ne permet pas à une onde sonique focalisée d'endommager un composant. Cependant, vous vous demandez peut-être pourquoi aurais-je besoin d'un nettoyeur à ultrasons alors qu'il existe des solutions de nettoyage pour PCB sur le marché? Bien que cela soit vrai, ils n'entrent pas toujours dans ces petits endroits difficiles à atteindre. Un nettoyeur à ultrasons peut vibrer à travers la carte et éliminer les petites particules de flux laissées par un nettoyeur qui ne pourraient pas l'obtenir. Voici quelques éléments à garder à l'esprit lors de l'examen d'un nettoyeur à ultrasons.
Choisir la bonne solution de nettoyage
Évidemment, si vous allez passer du temps à trouver le bon nettoyeur à ultrasons, alors vous voulez vous équiper de la bonne solution à utiliser. Le mauvais nettoyant peut faire beaucoup de mal à votre PCB lorsqu'il est appliqué à certaines fréquences. Pour l'électronique, les solutions de nettoyage qui fonctionnent avec le verre, la céramique, l'optique, le plastique et les PCB tels que l'Elma Tec Clean A1 sont des choix optimaux. Ils peuvent éliminer le flux, la poussière et toute autre petite particule dont vous ne voulez pas sur votre carte de circuit imprimé.
Préparez correctement votre solution et votre appareil
Certaines solutions de nettoyage nécessitent quelques modifications avant d'être utilisées directement avec le PCB. En effet, ils peuvent contenir des bulles d'air. Pour éliminer l'air, vous pouvez mélanger la solution avec la bonne quantité d'eau et démarrer le nettoyeur à ultrasons pour éliminer l'air. Cela a également l'avantage supplémentaire de mélanger la solution et l'eau assez soigneusement. Une fois qu'il n'y a plus de bulles d'air, vous êtes prêt à utiliser le nettoyeur à ultrasons sur vos PCB.
