Tillverkning av ett
Dubbelsidigt Flex Kort!
Jag gillar komplicerade
funktioner gjorda av
sofistikerade material
på en liten yta!

Robust Konstruktion
• Denna uppbyggnadsmetod är den mest
använda, och producerar de mest robusta
och tillförlitliga Flex-Rigid korten.
• Inget Lim i de pläterade hålen.
• En hård ytteryta (Rigid) för alla
komponentplaceringar, tillåter användandet
av en foto definierad lödmask.
