You may want to pre tin wires then dip into flux before soldering Does work!

If there is a way to pre-tin the parts, that might help in forming better joint with gold.

Try to pre-tin the part. This should give you a lot of answers.

We're having a lot of problems with failed solder joints to gold-plated MOSFET leads. Gold plate thickness spec is 60uin, but we've seen as much as 200uin in cross-section, so we're obviously concerned about gold embrittlement issues. Pre-tinning w

Hello All, I recently had a case of excessive tin coming from a solder pot sample. The solder is SN63 but the results of testing had a 64.97% for Sn. The J-STD-001 spec is 61.5% to 64.5%. The pot is used to pre-tin wires which will then be solder

as the title says, should gold pads be pre-tinned, and are there any issues with soldering to gold pads?

Curious, but thoughts are: * Your pretinning pot is loaded with gold that has been removed from lead over a period of time * Your failed solder connections are caused by something else other that gold intermetallics * Your tinning process is undiscip

"and dip it in your solder bath for 10-20 seconds." Do you pre-tin them first or just dip them in regular solder? "You can't talk to molten solder, but surfactant will listen." "Remember, we're all in this together."

Have you checked the parts for contamination? Are the voids out of spec? IPC allows some voiding, especially with lead free solder. Component contamination can cause this to repeat, as well. Try pre-tinning the component in question, and see if s

Does anyone know how to use the Pattern matching option for fiducials at Philips Topaz or Emerald SMT machines? Is it worth using it? Can it be used for example when you deal with hard to recognize fiducials like those on pre tinned PCB's?
