Explore Hongchuan Metals technical guides, product information and company updates. Review PCB busbar, solder terminal and SMT nut selection considerations alongside the product catalog.
When a PCB welding terminal overheats, turns black, loosens, or discolors the board edge, the root cause is rarely one p...
AI servers and GPU power architectures are pushing 48V board-level power delivery into higher power density. A 48V bus c...
When a high-current PCB starts depending on 2oz or 3oz copper, wider traces, or parallel layers, cost, process window, a...
AI servers and GPU racks are pushing data center power design from ordinary distribution into high-density, high-current...
Welding-terminal selection is not only about thread size. Behind common options such as M4, M5, and M6, the real decisio...
In high-current design, a busbar cross section should not be scaled only from the current number. For 100A and 200A appl...
There is more than one way to build a high-current PCB connection. SMD copper bars are better for board-level current sh...
Reliable SMD copper bar performance depends not only on the metal part itself, but also on pad area, solder paste openin...
When ordinary FR-4 PCB copper cannot balance current capacity, temperature rise, layout space, and production consistenc...
There is no single fixed current value for a PCB trace. Copper thickness, trace width, layer position, allowed temperatu...
This guide explains why high-current PCB terminals heat up and how engineering teams can check contact resistance, tight...
This guide explains how SMT nuts and self-clinching nuts differ in assembly order, joining method, panel-thickness limit...
