Normally paste manufacturer specifies stencil life of a paste is 10 hours. the question is, if i run a continuous manufacturing for 40 hours, we will be adding 250 g of paste for every two hours. The addition of 250 g will be mixed with the paste whi

So true, We had paste flux supplied to us from Alpha metals. It was the same as used in the solder paste. The major problem we noted was the in ability to control the ratio of paste to flux resulting in lots of voids. When we mixed enough to get the

Thanks for you reply CL. For Q2, I want to know that is there are any ratio of mixing new or old soldering paste? Also, can we put the "working jar" and opened unused solder paste to refrigator and soft it by solder paste softer in next time of prod

When you measure "solder paste heigth of 7 & 8 mils using a 5.0 mils stencil," are you measuring the top of a flat brick? Sometimes if you snap-off the stencil too fast, the paste touching the stencil walls form peaks along the edge of the brick that

What exactly is the criteria needed to determine the right solder paste. I have been fortunate enough in the past to have a solder paste work "halfway" for me and to modify the reflow profile or simply just "drop in" a paste and monkey with the profi

Sometimes solder balling is related to oxidized paste or paste that has sat on the pcb too long before reflow. Mostly it is related to process, sorry... Too slow or too fast of a reflow ramp rate. Heating up an assembly too quickly will not allow the

Pardon me for being so bold, but I still cannot understand to this day why solder paste thawing is an issue. I am not sure what types of paste you all are using but it has been my experience that the only thing you gain by refrigerating is 3 months
