MULTILAYER BUILDS

[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]This section describes the different materials available for multilayer circuit boards and the basic guidelines governing stacking possibilities.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_tta_accordion color=”black” active_section=”” collapsible_all=”true”][vc_tta_section title=”Basic guidelines” tab_id=”reglas-basicas”][vc_wp_text]A multilayer circuit board is made up of 3 groups of materials:

Cores: sheet of dielectric material covered with copper on both sides.

Prepreg: sheet of dielectric material pre-impregnated with resin to join the different layers of a multilayer circuit board.

Copper sheets: sheet of copper with a uniform, controlled thickness, used for the external layers of a multilayer circuit board.

Basic structures:

Basic 4-layer stack-up

Basic 6-layer stack-up

Given the wide variety of materials available, it is possible to design boards with different thicknesses and electrical specifications. Nevertheless, in order to avoid any possible difficulties in the manufacturing process or mechanical distortions in the circuit board, it is important to follow the guidelines below:

Create symmetrical builds

Do not stack more than 2 prepegs in a row

Use the same thickness of copper on symmetrical layers. Cu top=Cu bottom // Cu int.1=Cu int.2[/vc_wp_text][/vc_tta_section][vc_tta_section title=”Materials available” tab_id=”materiales-disponibles”][vc_wp_text]
