We are considering converting from a water wash wave solder porcess of carbon ink touch pad buttons to a no-clean process. Since the carbon ink buttons are exposed to the molten solder, we are concerned about the residue that is left behind from the

Sorry about the non SMT post, but I figured that there might be someone with a similar experience out there. We have been having a tough time cleaning the conveyor chains in our wave solder machine. We have been cleaning them in a self cleaning oven,

Good Morning SWAG, We have had similar problems with our Heller 1800 EXL's when the chains would build up oil and debris. The only way we could get them clean was to put them into a self cleaning oven and carbonize the residues. We then rinsed them

On the dendritic growth over the top of the capacitor: We agree that your capacitor supplier probably did not do a very good job of cleaning process residues from their device. On the metallic fragments under the capacitor: This sounds like solder

Greetings All, Anybody out there experiencing white residues after cleaning? We currently use a batch cleaner to clean water soluble fluxes. this cleaner makes its own DI water by means of carbon and resin tanks. After cleaning there are residues

Hi davef, Thanks for the suggestion. I have inspected the heaters but I think they are OK (no visible coating, deposits, etc.). Unfortunately, I'm not sure that the residues are ionic. It was just preliminary report of the person responsible for the

I had problems with white residues on both WS609 and WS 3060.The WS 3060 turned out to be a carbonized material.The composition after analysis (Energy Dispersive X-ray spectrum) turned out to be tin,tin,phosphore and cloline and tin. Alpha also have

Hi All, Let me summarize the key facts and findings: 1) This is not a permanent problem. Only one production batch was affected. The cleaning solution was exchanged and now the cleaning process runs normally. 2) Probably the residues are not ion

Q: Could any of you guys tell me what exactly is this greenish thing ? A: No, but is not copper oxide. Copper oxide is brown, the color of a penny [here in the US] or an untreated copper laminated trace on a board. Many copper salts are greenish in

@ Westshoredesign: Go take the top covers off your XPM's. Tell me if you see flux residue on the blower motors and the surrounding area. If you see this, grab ahold of the blower motor and rock it back and fourth. It is moves, the seals are melted o
