soldering to hard gold plated PCBs

Does anyone know if I will have problems soldering surface mount components to an all hard gold plated PC board. We want to use hard gold similar to gold used for edge fingers because our customer is concerned about wear and conductivity of connector

For soldered areas, we like to keep gold thickness substantially below the maximum you propose. Search the fine SMTnet Archives for our discussions on the topic of acceptable levels of gold with solder connections. Let�s fix this �no one seems be s

Comments are: * Use an eraser if the surface of Au is not clean, but make sure the eraser has no/low ionics (such as sulfur that is a common additive for rubber). * If the plating surface required eraser to remove the top surface, the plasma normally

| hi, | i am working towards developing a no-clean process for a customer at contract manufacturing facility. the assemblies have gold fingers on them. these are masked to prevent from any damage to them during reflow soldering. the earlier proces

yea - yippie- Scott's the man!!!! good answer - I support the notion that in the long run, stopping the line, getting the root cause determination, is not only effective but efficient. It is hard to do because we all are so used to fire fighting on

Thanks for cluing me into IPC-2221. Though the numbers they give seem to contradict what I have learned from people working with the materials. At least I now know where the guideline for a max of 30 microinches of gold for soldering comes from. But

Measured the pot temprature independantly from the software (268C/514F from moving wave). We are using Dross Inhibiter Tin/P Regenerator from BLT. Monthly sample checks are carried out on the solder bath and are all within limits. It will be hard to
