I have many question about pcb.
I have copper clad board but i don't have material which used in etching of pcb..
FeCl3 is used in pcb etching but power of FeCl3 is very expensive.
And I saw a electroless tin plating pcb..
Please tell me what is electroless tin plating pcb and suggest me other methods of etching pcb and website where i can buy fecl2 in inexpensive rate.
Thanks..
