Advantages of using a stencil cleaner verses manually cleaning stencils: 1. Using a stencil cleaner ensures no direct contact between operator and solder paste (lead being the primary concern). 2. Most stencil cleaners remove 100% of the solder p

Hi Stuart, just to be clear right from the start I work for Asymtek, so you know where this reply is comming from. I agree with Jax and Micah that to purchase Fuji or Camalot will probably be a system that you are more familar with, so the learning

Donnie is correct. "NO-Clean" doesn't translate to "no-residue!"..... who's giving you hassle about this - your ICT guys??!! Residue remaining on your PCB substrate is a function of many different things - flux deposition, solder mask (glossy means

Marc: My experience found reliability IS a function of operator skill and attension to the process. Expecially for some RF assemblies. I worked with an engineer from Rogers to develope a process for reworking Pads for a special material. (I thing

Cartman: Ah, another "hidden cost" of no-clean. I love no-clean people they're putting themselves out-of-business and they don't even realize it, but at least they're saving money. Enough pontificating, "yes" to all of the above. 1 Yes, no-cleans

So far, I have not been able to get any consistant or good results using one of these "problem solvers". I have managed however, to screw up some good processes. I believe that this technology can work though. I would reccomend contacting Speedlin

Hong Guan: When thinking about high nickel alloys: � Kovar, Alloy 42, and Invar are generally thought of as hermetic sealing materials, because of their coalescence with glass, platabililty, and coefficient of thermal expansion properties. � Permall

Steve: Wadja mean "I fixed it, now tell me what I did to fix it." Steve, you�re one scary guy. ;-) "Steve�s Longer Pad Theory" - Stubby pads will not make solder flow-up the leads of a QFP100, leaving sparse solder on the pads. Given a choice, s

Dave is absolutely right. Leave the capital expenditures up to the engineer types. As you become more experienced, they might ask your opinion, but for now let them do their jobs. From the sounds of things, you might have began your career as an e
