PCB multicouches de haute précision avec contrôle d'impédance
JLCPCB peut produire des cartes multicouches de haute précision avec des capacités répertoriées dans le tableau ci-dessous.
Largeur/espacement de piste min. | Via min. | BGA min. |
---|---|---|
3.5mil | 0.2mm | 0.25mm |
Il est très pratique pour les clients de réaliser une conception d'adaptation d'impédance, selon la structure stratifiée de JLCPCB et les paramètres associés. Le PCB sera strictement produit conformément au stackup suivant.
Paramètres d'impédance contrôlée du PCB et stackup
1. Constante diélectrique du préimprégné :
Type de préimprégné | Constante diélectrique |
---|---|
7628 | 4.4 |
3313 | 4.1 |
1080 | 3.91 |
2116 | 4.16 |
2. Paramètres du masque de soudure
Revêtement au-dessus du substrat C1 | Revêtement au-dessus de la piste C2 | Revêtement entre les pistes C3 | Diélectrique du revêtement CEr |
---|---|---|---|
1.2mil | 0.6mil | 1.2mil | 3.8 |
3. Constante diélectrique du noyau
