Homebrew PCBs

HI John

is same as for multilayer board 

it use very thin FR-4 PCB (single or 2 side)
then it hot laminate it to aluminium plate whit a Prepreg
bethen pcb and the metal core 

but for laminate it you need a hydraulic press capable of heating
to 230-250 deg Celsus so above glass transition point of FR-4

Prepreg sheet was aviable from lpkf or local pcb shop 
it look like paper thin fibre glass fabric whit resin on it

as for press i personally use 2 1/2" thick aluminium plate
on on a metal frame 1" thick bolted together the 4 corner
and put it on kitchen over
for 60 minute then let it cold down for another 60 minute

for multilayer it same but you replace metal core whit 2 or more 2 layer PCB each one separated by a Prepreg sheet

then drill and plate via 

Best regard
