We use both, cartridges for water soluble and jars for no clean. The only reason we do is so they can't possibly (knocking on my head) mix it up. Pros: Jar - you can put paste back into it if you want to wash your stencil, change jobs after lunch,

Hi Steve Thanks for your reply. Your comments make it sound like it may be the nature of this paste. Any one else agree? Paste control is fairly good. Paste is put in fridge straight after it arrives at inwards goods, (4deg). Removed from fridge

Hi, Jar's quality is easier to measure. If you want to know paste viscosity etc. it's easier if you use jar. I have bad experiences about cartridges. I used cartridges for a short time but I change it back to jar because flux separated too easily in

There are plenty of paste chemistries now that can be stored at room temp for far longer than 2 weeks. You should not return a paste to the fridge once it has been opened. If a tub of paste came out of the fridge mistakenly I see no reason to why it

Thanks for the info, Here is a couple more questions (and you thought you were done) What size are these caps /res? how thick is your stencil? what type of oven are you using? what is the finish of the board? Anyway, it seems like (from a distance)t
