Dual-Tip Anti-Etching PCB Ink Marker | High-Temp Resistant

Take your electronics prototyping and DIY circuit board projects to the next level with the Dual-Tip Anti-Etching PCB Ink Marker. Engineered for hobbyists, makers, and electronics enthusiasts, this specialized marker lets you draw precise traces, mask pads, and protect copper surfaces on PCBs with ease — all with a single versatile tool.

Why You'll Love This PCB Marker

• Dual-Tip Design: Features two tip sizes in one pen — use the fine tip for detailed trace work and the broader tip for covering larger areas and masking pads quickly.
• Anti-Etching Ink Formula: The specialized ink resists chemical etchants, making it ideal for DIY PCB fabrication. Draw your circuit traces, etch away, and your lines stay perfectly intact.
• High-Temperature Resistant: The cured ink withstands elevated temperatures encountered during soldering, so your markings hold up through the entire board-building process.
• Available in Multiple Colors: Choose from red, black, or blue to suit your workflow, color-code different circuit sections, or simply match your preference.
• Precision & Control: The fine tip delivers clean, consistent lines — perfect for tight PCB layouts and intricate DIY circuit board designs.
• Ready to Use: No mixing or preparation required. Uncap, draw, and get straight to work on your electronics project.

Perfect For

• DIY PCB prototyping and home etching
• Circuit board repair and trace touch-ups
• Electronics hobbyists and makers
• Engineering students and classroom projects
• Craft and mixed-media art projects requiring chemical-resistant ink

Frequently Asked Questions

Q: What makes this PCB ink marker anti-etching?

A: The dual-tip anti-etching PCB ink marker uses a specially formulated ink that chemically resists common PCB etchants (such as ferric chloride). When you draw circuit traces or mask areas on a copper board and submerge it in the etching solution, the ink acts as a protective barrier — only the exposed (unmasked) copper is etched away, leaving your drawn traces clean and intact.

Q: Is the ink truly high-temperature resistant, and will it survive soldering?

A: Yes. The ink formula is designed to withstand the elevated temperatures typical of soldering work, so markings and protective masks won't break down or smear during the soldering process. This makes it a reliable choice for the full PCB prototyping workflow — from drawing to etching to soldering.

Q: Which color should I choose — red, black, or blue?

A: All three colors use the same anti-etching, high-temperature resistant ink formula, so the choice is mainly a matter of preference or workflow. Many makers use black for primary traces, red for voltage rails or important markings, and blue for ground planes or secondary notations. Any color works equally well for DIY circuit board etching and repair.

Q: Can this marker be used for purposes other than PCB work?

A: Absolutely. While it's optimized for DIY PCB prototyping and circuit board repair, the chemical-resistant, heat-resistant ink also makes this marker useful for labeling components, craft projects requiring durable markings, or any application where a permanent, resilient ink line is needed.
