Has anyone come across any good visuals for the solderability requirements for component leads with toe-down configuration? IPC-A-610 does not have any visual aids for this category and our inspectors are having a difficult time assessing based sole

Hello Can someone recommend a cost effective solder printer that does not require stencils. We are currently using a Speed Print 200 machine but this requires us to spend a lot of money on stencils and wait long lead times for these to be manufactur
