I'm trying to get a better understanding of the cooking process of pcb's. The use of nitrogen in reflow and wave ovens. Seems to have a wide margin of acceptance as a standard gas to prevent oxidation of metals in the board. Has any one heard or us

Hello James, It sounds like the system that's being used to gather this data is an AOI system. I will investigte this more because I'm very curious of the process in which this works. I'll keep an eye out for someone using this setup and may get back

If people use an inert gas, they use nitrogen for mass soldering. Inert gases get progressively more expensive as you move down the periodic table. Many times no-clean flux is less active than other flux types. So, people use an inert gas to lower

There are several alloys had been using in the industry. For SMT: most people use SAC305 For Wave: most of them use SAC305,SC100C,SCS7,and SACX0307. Of course, different alloy composition have its own recommended profile. There is no such rule tellin

We're using Sn100C at wave. Well, to be fair, in a static solder pot; as we don't have a lead-free wave machine in operation at the moment. We've had generally good experiences with the SN100. Good soldering; some blow holes, but, since we're usin

Has anyone ever had a problem where all the pay per use buttons show no credits regardless of how many credits are on them? Any fixes?

Usually the print specifies the material since the design is qualified with it in place. I've used several from Scotchweld 2216, Scotchweld DP190, Hysol E-20HP, to NASA outgassing qualified Masterbond 10HT.

Hi All, I have a question to ask. Do we really need ESD kapton tape to be use inside SMT line/ production? Anyway the purpose of the kapton tape is to protect gold finger/ wirebond area from solder splatter. Please advise.

Understand that one..but the main issues is..do i really need to use ESD tape or non-ESD tape..since as we all know kapton tape is already expensive..if ESD kapton tape required in SMT line..the cost will be more higher.
