Hey Bob, Boy, you are lucky to have a laboratory, and now colorful pix!!! The only silver IMC that you will see are: * Ag6Sn, much less likely at 'normal' soldering temperatures * Ag3Sn, much more likely Allowable silver concentration: * Below 2%

We are deeply involved with this question because we have developed a much faster way to remove moisture from PCB's. PCB's absorb varying amounts of moisture at differing rates. The rate is influenced by the laminate type board configuration , loca

In this investigation a test matrix was completed utilizing 900 electrodes (small circuit board with parallel copper traces on FR-4 with LPI soldermask at 6, 10 and 50 mil spacing): 12 ionic contaminants were applied in five concentrations to three different spaced electrodes with five replicas each (three different bare copper trace spacing / five replications of each with five levels of ionic concentration). The investigation was to assess the electrical response under controlled heat and humidity conditions of the known applied contamination to electrodes, using the IPC SIR (surface insulation resistance) J-STD 001 limits and determine at what level of contamination and spacing the ionic / organic residue has a failing effect on SIR.
