Safety Notes:

Age Recommendations:
The American Flag Soldering Kit is intended for ages 16+ with qualified adult supervision. Users 18 and older may operate it independently but use at your own risk—you are solely responsible for your safety.

Mandatory Safety Requirement
All users—regardless of age—must read this websites Home Soldering Safety course before beginning assembly.

Recommended Soldering Equipment & Supplies

  • Soldering Iron Tip: Use a conical tip for best results.

  • Tip Maintenance: Clean and tin the tip with a wet sponge and wire solder (rosin or no-clean flux core). If the tip cannot be properly cleaned and tinned as described in the assembly instructions, replace it with a new tip.

  • Solder: Use wire solder with rosin or no-clean flux core. Choose the thinnest diameter available for precise control over solder application.

Quality Classification
Perform all quality inspections of your work in accordance with IPC‑A‑610, the industry standard published by IPC (Association Connecting Electronics Industries), a global trade association for electronics manufacturing. IPC defines three quality classifications:

​

  • Class 1 – General Electronic Products: For products where basic functionality is the primary requirement.

  • Class 2 – Dedicated Service Electronic Products: For products requiring extended life and reliable performance.

  • Class 3 – High‑Reliability Electronic Products: For products where continued performance is critical and failure is not acceptable.

​

Quality Target

For all LED American flag soldering kits, the target quality standard is IPC Class 2, although Class 1 is considered acceptable.

​

ESD Equipment

For safety reasons, ESD protective equipment is not recommended for this soldering project. However, if you choose to use ESD protective equipment anyway, please read my ESD Prevention at Home course, before beginning assembly.
