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

I am trying to convert a customer from a water wash process to no-clean but am receiving much resistance. They suspect that no-clean residue played a part in field failures they experienced several years ago. They are quoting an AT&T study that state

esoderberg: So, why do you want to clean your no-clean flux residues?

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

i am working on a no-clean process implementation project in a company. i want to change a board to no-clean which had dendrite problems underneath the small resistors on the bottom side(in smt).i want more information on the exact cause of dendrites

Hello All, Is Ionic Cleanliness testing using say an Ionograph on No-clean assemblies a valid test? If not, why? I understand factors like PCB cleanliness but is the 1.56ug/in2 IPC criteria valid for no-clean assemblies and can an Ionograph be used

Does anyone know of a reason, other than visual, contact, or testability, for cleaning a no-clean residue off a board? Are there any SIR or long term reliability advantages to cleaning a no-clean residue?

Is it possible to have a no-clean flux that could be removed with water. I would like to use a single flux at wave solder that could satisfy both no-clean and water soluble customers, within a contract manufacturing environment. Thanks, Tim A.

I am new to the No-Clean Process. When preforming rework in a No-Clean Process, should the rework technician clean the excess flux used to change a component or place a component missing?

I recently finished analysis of no-clean fluxes and Ionic contamination and cleaning processes. The results were eye opening. Summary: If you clean a no-clean you better do a good job. Many no-cleans produce a "waxy binder" to encapsulate the tro
