The process is especially advantageous when plating irregularly shaped objects, holes, recesses, internal surfaces, valves or threaded holes. With over 40 years of experience ­­­in delivering high quality, on-time PCB prototypes, Sunstone Circuits is committed to improving the prototyping through production processes for the. The (through) hole’s conductivity is due to electroplating as well as its tube or rivet lining. IHI Connectors brand. I used some electroless tin plating solution to tin plate the copper traces on a PCB that I made in a class in college, years ago. ” Can this be done with immersion plating? Is there a simple process for doing this? Also, is immersion plating the same as electroless plating? K. White Published 2008 When an iron substrate is immersed in a solution of copper sulfate or silver nitrate, the. The copper plating that fills the via then wraps over the top of this external pad, forming a butt joint between the copper fill plating and the via pad. pcb plating Manufacturers Directory ☆ 3 million global importers and exporters ☆ pcb plating suppliers, manufacturers, wholesalers, pcb plating sellers, traders, exporters and distributors from China and around the world at EC21. Electroless copper plating solutions comprised of 0. The chemical composition of the electroless copper plating solution was the same as that in the literature , and the compositions are shown in Table 1. 08 micron thick layer of organic metal, which optimally prepares the surface for subsequent tinning and then prevents diffusion of copper through the tin. Although the palladium catalyst has been commonly used in PCB metallization, the palladium catalyst is expensive.
