Read MoreIntroduction to the Process Characteristics and Workflow of Selective Soldering for PCB Circuit Boards
In the evolution of PCB technology, a notable trend has been the adoption of reflow soldering. Traditionally, reflow soldering was used for surface-mount devices (SMDs), but it has now been extended to through-hole components, known as through-hole reflow soldering. This method allows all solder joints to be completed simultaneously, minimizing production costs. However, the application
Read MoreManufacturing Process and Prototyping Challenges of Multilayer PCBs
Currently, most PCB manufacturing processes use the subtractive method, where excess copper foil is removed from the raw copper-clad laminate to form conductive patterns. Manufacturing Process of Multilayer PCBs The subtractive method primarily employs chemical etching, which is both economical and efficient. However, since chemical etching attacks indiscriminately, the desired conductive patterns must be protected
