Fourth, it has lower loss and enhanced expansion of the z-axis. Finally, it is capable of many lamination cycles, via-filling, and lead-free assembly.

Crucial Parameters Process in Laminating FR408HR Material

The essential parameters process in laminating this particular material is simple; it undergoes five (5) primary areas.

Firstly, before lamination, we retain the inner layer and make sure the FR408HR prepreg is dry. Next, we control the press’ pace of heating up for lamination.

Third, we always ensure that we’re employing the right amount of temperature during the lamination to avoid damaging the product and ruining the process.

Then, we carefully calculate the curing time in developing the TG transition. Finally, to avoid warpage, we subject it to a cool-down temperature.
