Ils prot\u00e8gent les composants contre l’humidit\u00e9, la poussi\u00e8re, la salet\u00e9 et les solvants. Les glob tops prot\u00e8gent \u00e9galement les composants sensibles contre les contraintes m\u00e9caniques et les rayures.[\/vc_column_text]\n

Ils offrent donc une protection parfaite contre la corrosion interne et r\u00e9duisent le couplage volta\u00efque local.<\/p>\n

De nombreux compos\u00e9s d’\u00e9tanch\u00e9it\u00e9 durcissent aux UV, ce qui permet un durcissement rapide en quelques secondes seulement. Ils conviennent donc parfaitement \u00e0 l’encapsulation de composants dans le cadre d’une production enti\u00e8rement automatis\u00e9e \u00e0 grand volume. Les compos\u00e9s d’\u00e9tanch\u00e9it\u00e9 \u00e0 durcissement thermique, quant \u00e0 eux, ont l’avantage de durcir m\u00eame dans les zones ombrag\u00e9es que la lumi\u00e8re UV ne peut atteindre. Les glob tops \u00e0 pigmentation noire, qui sont utilis\u00e9s comme couvercles ou rev\u00eatements, ne peuvent normalement \u00eatre durcis qu’\u00e0 la chaleur.<\/p>\n

Apr\u00e8s polym\u00e9risation, tous les compos\u00e9s d’\u00e9tanch\u00e9it\u00e9 glob top Hoenle r\u00e9sistent \u00e0 des temp\u00e9ratures pouvant atteindre 280 \u00b0C pendant de courtes p\u00e9riodes et ne sont pas affect\u00e9s par les processus de refusion. Les colles glob top Hoenle sont faciles \u00e0 mettre en \u0153uvre, tr\u00e8s flexibles et pr\u00e9sentent une r\u00e9sistance \u00e9lev\u00e9e au pelage et au cisaillement.[\/vc_column_text][\/vc_column][vc_column width=\u00a0\u00bb1\/3″][vc_single_image image=\u00a0\u00bb1674″ img_size=\u00a0\u00bbfull\u00a0\u00bb css=\u00a0\u00bb\u00a0\u00bb][vc_column_text css=\u00a0\u00bb\u00a0\u00bb]Les Glob tops\u00a0prot\u00e8gent les composants sur les cartes FR4[\/vc_column_text][vc_column_text css=\u00a0\u00bb\u00a0\u00bb]Downloads<\/p>\n

Les colles \u00ab\u00a0Black & Light\u00a0\u00bb<\/h2>\n

[\/vc_column_text][vc_column_text css=\u00a0\u00bb\u00a0\u00bb]La nouveaut\u00e9 r\u00e9side dans le fait que bon nombre de nos colles noires peuvent d\u00e9sormais \u00eatre durcies \u00e0 la lumi\u00e8re UV en couches \u00e9paisses. Cette nouvelle technologie Black&Light permet un durcissement complet \u00e0 la lumi\u00e8re UV sans avoir recours \u00e0 des m\u00e9canismes de durcissement secondaires. Cette technologie est compatible avec la plupart des colles Vitralit\u00ae \u00e0 base d’\u00e9poxy de Hoenle. En fonction de l’application, la coloration noire et l’\u00e9paisseur de la couche des colles peuvent \u00eatre ajust\u00e9es individuellement.<\/p>\n

Un autre avantage majeur des nouvelles colles \u00ab Black&Light \u00bb est leur stockage : alors que les colles \u00e0 base de r\u00e9sine \u00e9poxy noire conventionnelles doivent g\u00e9n\u00e9ralement \u00eatre conserv\u00e9es \u00e0 tr\u00e8s basse temp\u00e9rature, les r\u00e9sines \u00e9poxy \u00ab Black&Light \u00bb peuvent \u00eatre stock\u00e9es et exp\u00e9di\u00e9es \u00e0 temp\u00e9rature ambiante ou r\u00e9frig\u00e9r\u00e9es, selon la colle.<\/p>\n
