Get some free samples if you can. We have at least a couple solder reps who would not sell you a jar untill you have tried a free sample first. Preferably with them on site when you try it to help you with any issues that might come up. They want to

Cartridges/dispenser systems supply even paste volume to the screen. This will help provide the most consistent squeegee roll as well as paste deposition on PCB. Messier, though = much printer maintenance. Some people also like to use a caulking g

At least here the solder paste industry is competive, and each rep wants to be sure you are using their paste properly. Therefore they are willing to help you out. They are afraid a competitor will come in and show you his paste is better when in f

Not sure, but I would guess we used less than 100, 500 gram jars last year. Next year probably double or triple that. I think for the first 6 months of operation or so (before I started) they were pretty much using only samples. Nowhere near what a

How about keeping a fridge near the line and only putting on the stencil what is needed, then topping up from the jar as & when? As soon as the paste hits the stencil flux will evapourate, and all of that time spent by people in labs developing comp

Wanted to get this out there to get a feel for what everyone is doing with their paste after they crack the original seal. The life clock obviously doesn't stop once its opened and at room temp so one cannot solely go by stencil life alone....I imagi

I received my sample jar of NC257-2 SAC305 from Aim, and while that may have been true about older Aim paste formulations, this stuff prints and reflows better than anything I have tried and more importantly there were practically no voids on a 256 B

Paste for dispensing differs significantly from paste for printing. [B Toleno Henkel Loctite]. So, if you compare paste characteristics: Characteristic of paste||Printable ||Dispensable Viscosity [million centipoise]||0.8 to 1||0.2 to 0.4 Metal cont
