I cant seem to get to that link but we tried everything we could think of and there was no way we found to get solder to adhere to the pads. I guess if you took a burnishing brush and polished the nickel off and got down to the bare copper you may be

water alone especially cold is not good enough, how do you check for hasl fluids when most residues left behind after improper cleaning are non ionic. Use 40C saponifier followed by heated rinse then cold rinse then DI rinse followed by dry.Nylon bru

I presume you are looking at low melting point solders. Firstly, I would consider running BOTH sides with the same paste - this will cut down the opportunities for a mix up with rework or retro-fit. Secondly, check that there is a cored wire availabl

Yes, the previous "non-balling" flux was alcohol based, but very weak activity. We found it was worth the switch to water-based, to get prettier solder joints - but...at the expense of having to "brush off" solder balls on a couple of assemblies wit

Hi All, Anybody knows good, repetable method of dispensing flux for micro BGA rework? 6x6 mm(0.5 mm pitch) The flux dispensing amount by brush may vary depending on operator etc. If operator dispense too much flux the BGA "swim".Around the BGA compon

Is there any reason a dish washer would not work? Our volume for this is really low ~20 per month. Currently we use contact cleaner and a brush to clean the contacts on a few connectors. I was thinking about going the Ultrasonic route but wondered if

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

I need to be sure of the Nickel/Hard Gold thickness to be specified on our drawing. We use hard gold on a slip ring pcb that has brushes riding over the conductive surface, so soldering is not the issue. I read through the hard gold vs immersion gold

I clean all fids with a fiberglass brush pencil so that I know there will be no rejects (it doesn't take too long). The problem is the machine lighting. My Essemtec machine uses a light ring (red LEDs) around the cam. Here's one of many documents th

Warm De-Ionized Water and a brush? If they water soluble... Realistically, We need to know what flux your working with. Typically the manufacturer will recommend a cleaning methods on the TDS, easiest to stick with that. If they are high reliabili
