Why is it people still prefer to do manual stirring of solder paste versus automated solder paste softener ? I learned that one of the dis-advantage of using the softener is that this method is actually seperating the metal and flux. Is there any oth

Under web search you type solder paste softener. It is meant to replace manual stiring process of solder paste prior use. I heard that the spinner/softener is no use as it will seperate the flux and metal content during the spinning process. But, I h

Hi,what exactly means automated solder paste softener? Explain me please and I promise to try answer you correctly.

Since you have used malcom softener, did you encounter and sudden rise of void level in the solder joints as compared to manual stirring?

Or is solder quality better with automated mixing?

Agree with Joe 100%, we recently brought one in from Malcolm for trial, this company had not practiced viscosity reading or anything in the process, the trail run was a great improvement in print, consistancy, deposition and formation of the solder b

Yngwie, In a previous life, I used a mixer made by Malcolm and was very happy with it. We used Alpha 609 WS paste and experienced no separation problems. The Malcolm equipment agitated the material in a non-concentric motion which tends to "fold

With heat, most underfills soften just before the solder melts. So, keep poking the underfill until you see it soften. Then, wait just the correct amount of time until the solder melts and quickly snap or torque the part from the board. BR davef

We are involved in a project for microBGA SAC rework. The pitch is 0.4mm and the devices are underfilled (softening 150C). The underfill comes off fairly easily but the pressure underneath the package as the underfill softens pushes up on the undersi
