4 days seems a lot. You could be losing flux activation causing poor wetting on the enig. Check your suppliers data sheets for paste life. If it was contamination on the PCB, you'ld expect other components to solder badly as well. Try using a bra

I witnessed this at our sister company. It seems to be their standard process. It is not my place to interfere with their processes. I was just curious if there was any chance of brittle solder joints or other defects that might be caused from the WS

could always use a potato? http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=9994&#Message56920 But seriously.. best idea is to stay away from any metal as the tin will likely dissolve and contaminate your solder pot.

Dross removal is dependent upon the "activity" in your solder pot and the usage of a inert or an "air" atmosphere. The more moving parts that agitate the solder and expose it to air, the more dross. Basics first and then the answers will make sense

First, most �thermal shock� recipes are not a reliability test. There is no relationship between the failures seem in these tests and in-use application. These tests show you the failures in these tests. That�s it!!! Second, accelerated life test

My company recently aquired an asymtek coating machine and I have been using Humiseal 1B31, an acrylic coating, in it to coat all the boards given to me. They have now come to me and asked if it is possible to run Humiseal 1A33, a urethane coating, t

Why don't you guys look at the "WORLD LEADERS IN SOLDER RECOVERY". EVS International make the EVS 3000 and EVS 6000 Solder Recovery Systems. Many other companies have tried to come up with different ways of recovering solder but the EVS is the best

Dont't bother to answer real idiots! I can relate to a similar problem. We also use SN100C alloy and the solder pot get(got?) contaminated with the alloys from the SAC305! How can this be? Strange thing happens during the soldering process, and it o

Thinner: Flux thinner, NOT paint thinner We kept a spare stone in thinner in inventory. We cut PVC pipe to size, cap in one end, screw thread on the other, stone inside, filled with flux thinner and covered with a screw cap. I don't remember who we
