We are currently doing lot of external heatsink PCB's with Aluminium heatsink which we hard anodize and we use polyimide adhesive for bonding of the heatsink.
Now we have a requirement from one of our customers for a PCB with an external copper thermal layer with HASL surface finish even on the external copper. Anybody can suggest on the process to be followed for this.
Will it be pcb > thermal plate > bond > HASL or
Thermal plate > HASL > PCB >bond
Also suggest what is the kind of adhesive to be used
