i have been down the DIY route and I don't want to go there again. I need something that can be adjusted in X, Y, Z. i had work make me something close to what I thought would work and it did not because I have to manually shunt the PCB around and it's a nightmare to lane up. I need good tensioning and then to be able to press down to stop the solder spreading under the stencil.
Yes i have taped down stencils up to nowwith a PCB either side of my target PCB, I did VQFN like that, it was fucking, fuckinf, fucking, hard work - not going there again.
I don't mind spending the money but I'm rather surprised at how poorly some of these things are sold considering the cost.
