I am looking for some guidelines on evaluating solder paste. I am specifically interested in No-Clean Pastes, as they are a completely new ball game when it comes to slump, tack time, stencil life, tack time, etc. Thanks for any and all help given

When running NPI's we used to use a Letraset Low Tack Double Sided Tape to place components onto the PCB to verify placement and to ensure that the program is correct. Letraset have stopped making the tape, what do others use?

Years ago when we ran a solder paste evaluation we used the 2.4.44 method mentioned above. What we did was to print several coupons and let them sit for various times to see how the tack changed over time. Our goal was to see how long after print w

I agree with Comatose; although, 30 seconds I feel is stretching it bit. I would say anywhere from 40-60 sec. 5 seconds for removal 15 seconds to install (tack) 10 seconds to solder 10 seconds for inspection There's no need to dress the pads. Use t
