Dear haile.david.amos,
Good day.
This is a courtesy email to let you know that a breakdown of multilayer boards show that it consists of 3 basic elements: thin rigid laminates, copper foils and prepregs sheets.
The prepreg has 3 main functions, that is to bond thin inner-layer laminates, to establish a dielectric spacing between copper layers and fill spaces and openings in the etched copper.
A very important issue is the practical build-up of the dielectric thickness between the circuit layers.
Comparison of different Prepreg.
Type of Prepreg | Finished Thickness | Resin Content | |
| mm | mil | % |
7628H（7630） | 0.213 | 8.4 | 50 |
7628（43%） | 0.195 | 7.6 | 43 |
7628（41%） | 0.185 | 7.3 | 41 |
2116HR | 0.135 | 5.3 | 57 |
2116 | 0.120 | 4.7 | 52 |
2113 | 0.100 | 4.0 | 56 |
1080 | 0.076 | 3.0 | 64 |
1060 | 0.050 | 2.0 | 71 |
1080=3.04mil, 2116=4.67mil, 7628=7.68mil
