I am experiencing a problem with a surface mount coax connector that over time pulls loose from the PWB. The connector has 4 small gold plated leads and we are soldering it to a flash gold board. A cable plugs into the connector and puts some const

I was just wanting to know some of the advantages/disadvantages of going gold immersion? Is this neccessary for Lead free?

Does anyone have any experience with fired-silver/platinum/palladium lead terminations soldering. I have had issues on nickel over gold plated boards but not with HASL'd boards with tin/lead pads. Is this the norm?

Well, I'm going to assume you: * Have a nichel barrier between the copper on your board and the gold / solder solution * Use a lead / tin near euthectic solder If so, I pick "C" - It doesn't matter. When concerned about copper tin intermetallics, t

Hi, What is the different between Electroless Nickel / Immersion Gold (ENIG) and Immersion Au. Are they refer to the same finishing? We has been using the Gold thickness (0.00005 - 0.00013mm) , nicket (0.0025mm) for all Gold finishing brd (Immersio

Hi Dave, Sorry about that. Specifically, I am referring to radial leads on a crystal. The leads are supposed to be gold plated but only 1/2 to 2/3 of the lead is plated. We bend the lead to form a foot which is soldered to a pad on the PCB. Normally

This connector was designed with gold flash plating and the lead's surface was become dull and some black mark was observed on the contact surface.
