PCB Applications

Equipment for Heavy Copper PCB Manufacturing

Heavy copper boards (for power electronics) carry high current in thick copper layers, which changes the demands on etching, plating and lamination.

Overview

This guide explains the role of heavy copper pcb manufacturing in PCB manufacturing, the equipment involved, and how to specify it correctly. Copper weights from 3 oz to over 20 oz require longer etch times with strong sidewall control, high-throw plating and lamination that fills the deep copper topography.

Where It Fits in the Process

Heavy copper stresses etching and lamination most, with plating building thick barrels.

Equipment Categories Involved

Key Considerations

Etch compensation and step plating manage the thick-copper geometry; resin fill in lamination prevents voids.

Standards and Compliance

Designs and processes in this area commonly reference:

  • IPC-6012
  • IPC-2152 (current capacity)
  • IPC-A-600

Selection and Comparison

Key trade-offs when specifying for heavy copper pcb manufacturing:

  • Standard vs. heavy-copper etching
  • Step plating vs. single plate
  • Resin-fill lamination strategies
