I did the same thing in ours (removed the chip wave). What kind of machine do you have? What I did on our TD machines, I added some extra channels to minize the solder "splash" on the void which is the reason more dross is formed. Hope this helps a

Could be that your temperature ramp up rate is too fast. This could cause the flux in the solder paste to burn off too rapidly. When that happens, it can expand as it heats up and burns off, causing the solder to get spread out from the pad.

Hello, I have a very strange problem in a Delta 3 vitronic soltec, drops of tin are fired from the solderpot, I already adjusted the flux profile but these tin stains continue to appear, B.R

Hello there, Most probably, since the solder balls are entrapped, it is a process indicator, but refer to IPC 610-6.5.3.1 on Excess solder / solder balls / splashes - it really depends on what class you are manufacturing, and the minimum electrical c

Hi, During SMT process, i found that solder splash on the gold pad. The distance between the COB pad with component pad is about 1.25mm. My question is what material can used to cover the COB pad without bringing contamination. And i am welcome to

Could it be from a dirty stencil, rather than from the pick and place operation? We've seen a number of occurences recently with solder balls near some of our fine pitch components...we eventually diagnosed as dirty stencils...excess solder on the b

Your customer is correct. You are doing something wrong in your hand soldering process. Solder balls are a process indicator. Areas to assess are: * Moisture content of the bare board * Thickness of the copper plating in the through holes * Temperatu

My company is looking for a vacuum that can handle being used to clean up solder splashes on the bottom of our wave solder machines and around the solder pot area in our ERSA Selective Solder Machines. In the past we would use a Shopvac but these don

we are obliged by customer specifications that there will be no glue despensing process on the production line.. also that the glue dispensing process is very complicated for this case .. we could have glue splash on top surface of pcb so that will
