We are changing over to a No-Clean paste soon and l was wondering how other people tackle the issue of stencil and PCB cleaning in high-volume production. The paste we are using is Cobar 325RX and its pretty sticky stuff let me tell you! Our proble

Q1 Can anyone explain to me what is the clean and non clean solder? A1 The trend away from CFCs has lead many users to evaluate switching to no-clean soldering processes. The term "no-clean" is actually a common misnomer when used to describe a flux

What is the difference of formulation No-Clean Sn63 with No-Clean lead free paste? Is there techniocal data in detail for performance property of No-Clean lead free paste (for example, viscosity, solderability, tack, print life, reflow profile)? Is

OA: as in Organic Activated type of Solder paste, meaning the flux vehicle is an organic type. which is actually a water-soluble type. this is the opposite of a NoClean type.

The design engineers I work with are blaming some circuit problems on what they think might be related to the no-clean flux residue. (It couldn't be the design.) Has any body else seen noise issues in high speed circuits related to no-clean flux resi

Please help us understand better what you seek. Is it: * Cleanable low residue solder paste * No-clean solder paste * Someother paste

When you say "clean solder paste", do you mean not "no clean"? "clean solder paste" is not a common term and I for one do not understand what you mean by it. I believe you mean "water soluble" Commonly there is "no clean" and "water soluble". The

I have run design of experiments on screen printers and most times people forget about the type of board you are running; the condition of the board; manufacturer of the paste as I have seen Type 4 no-clean no-lead pastes react very differently using

You are correct in your assessment that no-clean pastes are difficult to clean. I understand why you would need to clean lots of stencils, but why would you need to clean "high volumes" of PCB's? If you are planning on cleaning high volumes of PCB'
