Does anyone know how to test for hard gold on a PCB? We are in a challenging situation with a PCB provider and we need some objective evidence other than wire bond failure to present to them. Any comments could help ....Thank you Anvil

Has anyone successfully replaced JUKI KE-2050/60RL HDD with the SSD hard drive?

To be short, no change in profile is going to get you through this. As I recall the point of hard gold is to retard the wetting process, so no surprise here. For example a connector might have hard gold plating at the mating surface, but not at t

Hi I meet problem by PCB with diameter 300cm and thick 6mm i used tin-lead with profile normal, soak time 60-90 sec, Temp peak is 220 degree C, But solder see not good, not shiny. Any body recomend help me to fix this problem for Hard gold playing.

you need to reduce your time above liquidus to as low as you can...maybe 10~30 secs to allow the solder to wet to the gold but minimise the amount of gold that is dissolved into the solder joint...try also reducing the peak temp to 200~210 deg C. Thi

Gold in solder alloys can be brittle. We always used to talk about keeping gold LT 3% in order to avoid embrittlement. Some military contracts require removal of gold from soldered contacts. Adding gold to a solder alloy that you're familiar with wi

You can create backup image of your entire hard drive using Acronis TrueImage or ghost. I use acronis and never had any problem. As for the hard drive size, "YOU DON"T HAVE TO BUY OLD USED HARD DRIVE". Size of the new hard drive does not matter if yo

And soon enough all of those management types who don't understand production will have sub'ed out our work and be saying to themselves... see that wasn't so hard was it?

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

Almost as crazy as using precision wood and paint brushes for high speed automation.
