Is there any harm in washing SMT soldered with NoClean paste? The PCA has some large thru-hole connectors that we would prefer to do as water soluble on out selective solder but the SMT consists of LGA's and other low parts that we would not be able

We currently use under-stencil wipe for in-process stencil cleaning. Our product goes in sensitive optical equip. Our customer is finding microscopic fibers we believe are coming from stencil wiping paper. Can anyone recommend a different process

We are looking for lint free rags to clean our circuit boards with. We use these when processing no-clean flux the operators will use a de-fluxer apply it to a rag and use a brush along with the rag to pull the flux from the board. Does anyone have a

Our latest designs are flip chip on flex based and we have issues with delamination/blistering. We know it is related to our vapor solvent (n-Propyl Bromide based) attacking an inner layer adhesive. Has anyone else ever heard of something like this?

A customer wants to coat a no-clean assembly to cut cost and cycle time. I know what wave flux I can use to make it work, but the Indium SMQ92J paste we use causes dewets. Any other no-clean pastes out there that play nice with acrylic?

My company is currently looking for a closed loop system that we could use for batch washing of PCBs. We primary use no clean flux and are looking for a system that we can use to clean the residue? Most likely we are going to have to add an additiv

I am currently using a water wash batch cleaning system, closed loop. I am looking for a better result when cleaning and thinking of introducing a chemistry. What is the best chemistry to use? Will using a chemistry to clean actually provide a bett

I am looking for IPC or other published standards that specify cleanliness levels for: 1) solder paste stencils 2) selective solder pallets When we cleaned PCB's we used a limit of 4 M-ohms. Now that we have transitioned to No-Clean, I am wonderi
