Single-Sided Copper Clad PCB Board FR4 100×200×1.5mm for DIY Etching

Single-Sided Copper Clad PCB Board — FR4 100×200×1.5mm

This single-sided copper clad laminate (CCL) board is made from FR4 fiberglass epoxy substrate with a 35μm (1oz) copper layer on one side. At 100×200mm, it is the standard size for DIY PCB fabrication using toner transfer, UV photoresist, or direct chemical etching methods.

Why Choose FR4 Copper Clad?

• FR4 Substrate — Superior mechanical strength and moisture resistance vs. phenolic (FR2) boards
• 35μm Copper — Standard 1oz copper weight; easy to etch with FeCl₃ or ammonium persulfate
• UL94 V-0 Flame Rating — Self-extinguishing for safe electronics use
• Smooth Surface — Excellent toner adhesion for laser printer toner transfer method
• 100×200mm Size — Large enough for most DIY projects; easily cut to smaller sizes

Typical Applications

• DIY PCB etching (toner transfer + FeCl₃ or ammonium persulfate)
• UV photoresist PCB fabrication
• CNC PCB milling (isolation routing)
• RF antenna ground plane fabrication
• Prototype circuit board for through-hole components
• Educational electronics lab PCB making

DIY Etching Process

1. Print circuit pattern on glossy paper with laser printer
2. Iron transfer onto copper surface (toner transfer method)
3. Etch in FeCl₃ solution (30–45°C, 10–20 min)
4. Remove toner with acetone
5. Drill component holes and solder

FAQ

Q: Can this board be used for SMD components?
A: Yes — with fine-pitch etching (0.5mm trace/space achievable with toner transfer). For finer pitch, use professional PCB fabrication.

Q: What etchant is recommended?
A: Ferric chloride (FeCl₃) is most common. Ammonium persulfate is cleaner and allows visual monitoring. Both work well with FR4.
