. James Hall are divided into 11 modules each with slides and a quiz on the following updated topics: PCB Basics and Surface Finishes like HASL and ENIG Surface Finishes like OSP, Immersion Tin, Immersion Silver Paste, stencils, printing and how they are interrelated Component placement with a focus
