How to build

  1. LV Macerator on a drawer of iron ingots: 1 ingot → 1 iron dust (GregTech macerator recycling, yield 1.0 in gtceu.yaml; you need 1 dust per 10 boards, so very little). — gtceu:lv_macerator, gtceu:iron_dust
  2. LV Chemical Reactor with ghost circuit 1: 1 iron dust + 3000 mB hydrochloric acid → 1000 mB iron III chloride + 3000 mB hydrogen in 20 s (30 EU/t). Acid comes by Pipez fluid pipe from the acid drum; the etchant goes into its own drum. — gtceu:lv_chemical_reactor, gtceu:iron_iii_chloride_bucket
  3. Hydrogen output: Fluid Voiding Cover on the pipe (or a steel drum). 300 mB of hydrogen per board you etch. — gtceu:fluid_voiding_cover, gtceu:hydrogen_bucket

Tips

  • One reaction (1 iron dust + 3 B acid) makes 1 B of etchant = 10 boards at 100 mB each.
  • The reaction gives 3 B of hydrogen back. The electrolyzer already makes exactly the hydrogen the acid reactor needs, so this hydrogen is surplus: put a Fluid Voiding Cover (switch it on with a soft mallet) or a drum on that output, or the reactor stops when its tank is full.
  • Sodium persulfate etches too (200 mB per board) but needs sulfuric acid and sodium bisulfate first. The pack’s cupric chloride etch (50 mB per board) needs an HV reactor (240 EU/t) and an EV mixer: not yet.
