Flex Flexible Circuits & Heaters.

Double-Sided Circuits

Double-sided flexible circuits consist of two copper layers encapsulated with dielectric, normally connected with a plated thru-hole (see diagram below). Double-sided circuits can be fabricated with or without coverlayers.

When to use Double-Sided Flex

• Required when circuit density and layout can not be routed on a single layer
• Ground and power plane applications
• Used for shielding applications
• Dense surface mount assembly

Double-Sided Features

• Component assembly available on both sides
• Two conductive layers
• Can be converted into a
