We are facing the problem of dry soldering in chip capacitor 0603. When we told the Vender then he just told that we are using solder paste with 62/36/2 combination & the components are lead free so there is prob. of dry soldering. While we are usin

It's pretty straight forward: Cartridges require a bigger inventory investment and a dispensor, but improve paste handling and mixing.

If you are experiencing flux migration, try refrigerating your paste when not in use. This causes the flux viscosity to go up. I have seen flux seperate from the solder is when it is VERY old and out of date.Sometimes warmer ambient temperatures wi

We have a customer transitioning slowly to lead free due to necessity rather than a need to comply i.e. some of their BGAs can only be purchased Pb free only. So for this we would want to produce them a leadfree soldered PCB (not necessarly RoHS comp

What I was told is that the stirring is intended to promote some shear thinning, not to redistribute the flux. The cartridges (and I'm assuming the syringes, too, if you're differentiating between the two) alledgedly introduce some shear thinning ju

Thanx for your only reply!! I already increased temprature now its actualy on board is 240*c. I would like to discuss one more thing if I go for lead free solder paste & using some components wich are not lead free then what will be the result. Has a
