Brush plating · Selective plating · Since 1970
Portable brush plating for electronics and beyond. Restore gold on connector pins, re-tin oxidized PCB pads and plate contacts exactly where they need it — at the bench or on the line, without tanks, masking or disassembly.
How it works
Brush plating — also called selective or spot plating — is electroplating without the tank. The plating solution is held in an absorbent tip connected to the positive lead of a DC power supply; the part is connected to the negative. Wherever the tip touches, metal is deposited.
Because only the work area is plated, there is no immersion, no masking of the whole part and no need to strip an assembly down. The Micro-Metallizer puts this in a self-contained, disposable pen cartridge.
| Tank plating | Brush plating | |
|---|---|---|
| Area plated | Entire immersed part | Only the work area |
| Disassembly | Part removed and masked | Plate in place |
| Where | Plating line | Bench or field |
| Solution | Open bath to maintain | Sealed pen cartridge |
| Waste | Bath disposal | No bath to dispose |
Each step is a separate pen on the same power supply. Swap the cartridge, keep working.
Step 01
Absorbent/degreaser pen removes oils and oxides from the work area. Stainless steel takes its own degreaser.
Step 02
A copper flash and nickel underlayer build a compatible base on substrates that need one.
Step 03
Brush the final deposit — gold, rhodium, silver, tin — only where the part needs it.
The system
Selective electroplating
Self-contained plating pens driven by a 12V DC supply. Deposit gold, silver, nickel, rhodium, tin and more exactly where the part needs it — no tanks, no bath, no waste handling.
Each kit includes the power supply and connector cables
Industries
Electronics & PCB
Electronics manufacturers and rework technicians rely on the Micro-Metallizer for precise, localized plating. The pen tip plates a single pad, pin or finger without bridging its neighbors or contaminating the board.
Restore connectors, contact rings and fasteners in place — without pulling the assembly for tank plating. The same pen workflow our electronics customers rely on — applied to aircraft connectors, avionics contacts, fasteners and fittings.

Order
Essential first step in any plating process. Cleans and degreases all metal surfaces (except stainless steel) before plating.
Plate pure 24-karat gold onto gold, nickel, or silver surfaces. Ideal for electrical contacts, jewelry repair, and decorative work.
Plate nickel over copper surfaces. Apply copper flash first on non-copper substrates. Essential underlayer for many plating sequences.
Plate tin over any metallic surface (not aluminum or chromium). Widely used in electronics for solderability enhancement.
