Currently, in my working factory, we facing the flux residue remain on connector after washing. (of course, this is clean process with WS solder paste). So, are there any ways to clean the flux residue rather than go back to wash again? Because wash

Sounds like you could have a problem caused by the gold. How thick is the plating? Are the connector leads gold too? I have seen gold cause dry looking brittle solder joints in the past.

I have a solder paste fridge; my question is what is the type of this connector so I can use it to attach a warning light. And is it a power source or is it a dry contact relay output?

when something like this happens I usually do a connector and PCB slot cleaning. apply contact cleaner and plug/unplug (slot/unslot) connector (PCB) few times then blow it out dry. do it for each PCB and connector.

Well i guess you would not have to dry the boards but let me ask this, Are you hand cleaning water soluble flux in a sink? Never seen a cleaner without a dryer. Anyway temp and time for drying is easy to figure out. When boards are dry you have i

I’m having trouble with the transfer of one board from the UIC conveyor to a DEk screen printer. They are set up for SMEMA to SMEMA but the DEK keeps asking for a aboard when it already has one. Then it will ask for one every 5-8 seconds. DO I have a

| We notice that DI water seems to tarnish or discolor the metal packaging on crystals and DIN connectors. Our marketing types like the shiney metal surfaces. We don't want to hand solder these parts after washing. | Any suggestions? | Dave F Dave,

We have a name brand aqueous batch cleaner that uses a chemical and DI water to clean ROL0 flux from our PCBs. It does ok most of the time for SMT boards and we want to include through hole assemblies as well which should be a better cleaning process

Hi Michelle, Due to the dense population of through hole on some boards, after a 35 minute wash, some connectors or battery holders remain wet. Currently we put them into drying ovens at 70c for a Minimum of a half hour. We do occasionally air dry un
