Hello Greg, I agree with you that the article in SMT Magazine should be studied very carefully as it contains many errors in respect to SN100C. The testing performed was a DOE and was not an optimized run. There is also a statement on dross generatio

Hello, I am automating a process on our floor from wire solder hand application to dispensed paste and reflow. The process involves "lidding" a shielding lid around our assemblies for microwave quieting. The result is non-hermetic. For cosmet

I am looking for an industry standard �stock� note to place on our printed circuit board assembly drawings that will capture a level of cleanliness for an IPC-A-610 class 2 board assembly. I�m looking for some quantitative spec for cleanliness that w

My company is currently using point source soldering of SMT components. We have seen some problems due to improper soldering and are looking to switch to a reflow oven/hotplate assembly. Our PCB's range in size but are no larger than 5"x5" and we as

Hi, One thing, getting back to the original topic, is you might want to panelize these boards as much as possible, as you don't have too many components, but you have some good volume. So the machine changeover time is going to be an issue. Althoug

I say: �Wave flux needs to be heated to certain activation temps which won't be repeatedly achieved with a manual soldering process. Plus, you won't burn off any residual activator as you would if the board were immersed in a solder bath.� Muse say

Has anybody else noticed a problem with Assembl�on's mechanical 12 mm feeders, with 4 mm pitch? We are experiencing grave pickup problems with a MELF diode packed this way and fed with this type of feeder. If I attach a hefty weight to the blister ta

Hi Guys, A few months ago I posted a question about a New Assembly Line, and It was great the answers I received. Now I would like to have an additional advise, to complete the requirements of my financial. We expect to install approximately 6 Pick

The process that burnt the tips up yesterday was hand soldering/touch up of lead-free assemblies. Not even assembly, but just touching up boards that we've soldered on a solder pot...which will lead to another question. We're using SAC 305 WS482 3
