My old boss bought some stuff to clean the lead off of gold fingers. At least that is what he thought it did. What it really did was remove the gold fingers. And quite well I might add. The short answer to your question is no. And if you replate mak

There are several surface treatment for PCB board: bare board (no treatment on the surface), rosin board, OSP (Organic Solderability Preservatives), HASL (lead tin, lead-free tin), plating gold, immersion gold, etc., these are relatively conscious treatment. Many people can't tell the difference between plating gold and immersion gold, thinking that it is the same thing, it is a big mistake. The following is a brief introduction to the difference between plating gold and immersion gold.

Interconnection technology relies very heavily on the ability of the conductors on a printed wiring assembly to maintain reliable signal integrity. Harsh environmental factors can precipitate a loss of conductivity due to oxidation and corrosion. Connections are typically soldered or inserted using pressure fitted connectors to obtain enough surface contact to meet the electrical conductivity requirements. In pressure contacts, surface integrity is especially critical where the abrasive effects of retraction and insertion can wear off the metallic finish from the contact area. This can expose the underlying copper or nickel and lead to increased resistance at the contact points. These types of conductors are frequently found in card edge connectors where the terminations are plated with a layer of nickel and gold (frequently referred to as gold fingers). A hard gold is typically used containing very small amounts of nickel and cobalt to increase the wear resistance.

For though hole soldering, no matter it's wave soldering or selective soldering, the process is same formed by fluxing,preheating,soldering. How these 3 process will change the soldering result? When you face the soldering defects, what could be the reasons caused these and how to debug them? With below information you may get some hints.
