I have asked that same question to a co-chair of the J-STD-001 committee who in turn checked with personnel at IPC. The answer I received is that yes you can apply the Class 3 assembly requirements using a class 2 PWB but the resultant assembly will

here is how it is done. 1.Position the stencil in the machine. 2.Position the board onto the PCB tooling as close to being aligned with the stencil as you can. 3.Place mylar or some thin clear material over the board. your printer should have prov
