Ratio pin-hole<\/h2>\n

Avec les composants \u00e0 trou traversant, les pines de connexion traversent un PCB. L’espace entre une goupille de connexion et le trou dans le PCB d\u00e9termine l’effet capillaire. Cet effet garantit que le flux et l’\u00e9tain liquide sont \u00ab\u00a0aspir\u00e9s\u00a0\u00bb dans l’espace entre la goupille et le trou.<\/p>\n

Un bon rapport entre la goupille et le trou est donc l’un des param\u00e8tres cruciaux pour un soudage r\u00e9ussi des composants \u00e0 trous traversants.<\/p>\n

Contr\u00f4le de l’effet capillaire<\/h2>\n

Il est important que le flux capillaire soit d’abord \u00ab\u00a0aspir\u00e9\u00a0\u00bb dans le trou afin que les surfaces du trou et de la goupille soient exemptes d’oxyde et que l’\u00e9tain de soudage puisse \u00e0 son tour monter de mani\u00e8re optimale.<\/p>\n

Pour obtenir l’effet capillaire le plus fort, la zone ouverte entre la goupille et le trou doit \u00eatre comprise entre 150 \u00b5m et 350 \u00b5m.<\/p>\n

L’utilisation de N2 a une influence positive sur l’action capillaire et est particuli\u00e8rement importante dans le soudage s\u00e9lectif. De m\u00eame, dans le soudage \u00e0 la vague, une atmosph\u00e8re de N2 a un effet favorable sur la mont\u00e9e de la soudure dans les trous.<\/p>\n
