SMTnet colleagues, I am looking for your opinions on the PCB/CCA cleaning process. Regardless of fluxes or population complexity I want your opinion on these three cleaning processes and what you consider to be the best for what and why. Thanks for

yes and thanks for this feedback. we clean with degreaser ( strong) and flux is rosin with 10% in the paste (koki). we clean after second reflow . the gap time from bottom to topside completion is 10 hours. cleans with this time. my even after 20 h

I guess my question would be why are you getting so much/leaving so much flux on the boards during the select solder process? With a drop-jet fluxer you should be able to apply the flux very selectively and leave a fairly clean looking PCBA, assumin

We are using a spray fluxer. Most of the THT parts are long connectors, so we spray along the length of the connector. I'm sure we can tune it a bit to reduce the amount of flux some. We're still going to need to remove the flux for some of our clien

The problem that we have seen applying NC flux (EF2210) at selective solder is that the flux overspray (relative to the nozzle path) did not see high enough temperature to activate the flux and turn it to a non-conductive, benign residue as one would

It is possible. If the talcum powder mixes with the chain lubricant, it could gum everything up. Back a few years ago when I was running an SMT Quattro Peak, I was having an issue with the conveyor chain drive motor going into overload. We had to pul

Obviously you are not as experienced as you think so I will help you out a bit.You are correct on the size of the wrench. I was trying to recall from memory but the wrench size is 8mm. The odd size I recalled came from the other side of the wrench th

Ummm...why not use Loctite 7360 Surface Mount Adhesive Cleaner? It's designed to remove adhesive and works great. Low oder and can be bought in 500ml cans for hand cleaning. Part# 25658. Use it why any dry wipe. Do not use alcohol to clean this

Has anyone got problems with their Fuji CP6* holders sticking and not indexing the nozzles? We find about 2 or 3 holders seizing up on us every two weeks or so. It's really frustrating, not to mention the damage it can cause on the machine and the
