Solder Resist Ink

Before Solder Resist Coating

Before Solder Resist Coating

Copper circuit pattern is exposed.
Danger of wiring breakages, shorts, and other electric problems

After Solder Resist Coating

Before Solder Resist Coating
  • Coated areas protect copper circuit pattern and provide sulation.
  • Non-coated areas provide contacts that allow electrical connections to be made for component mounting.
  • Preventing solder from adhering to unnecessary areas

    Solder resist prevents solder from adhering to areas other than electrical contacts and thereby causing short circuits when various components are soldered onto a printed wiring board.

  • Protecting the circuit pattern from dust, heat, and moisture

    Solder resist protects circuit patterns from the affects of dust, heat, and moisture, ensuring that electronic devices will work for a long time.

  • Maintaining electrical insulation between circuit patterns

    With the miniaturization of electronic devices, circuit patterns on the average board are now in the region of 50 to 150 µm, and are even thinner on package boards. Solder resist ensures that the circuit pattern remains insulated, and prevents shorting.

Purpose of solder resist

Taiyo ink’s solder resist has been applying extensively on various electronic device, like desktop, smart phone, automobile..etc
