<p>PURPOSE:To improve a marking property and the identification after marking by coating, drying or curing a laser marking resin on the prescribed portion of a resin-sealed electronic component, and then laser-marking it. CONSTITUTION:After laser marking resin is coated, dried or cured on the prescribed portion of a resin-sealed electronic component, the portion is laser- marked. The resin of the component may use all synthetic resins such as sole or mixture, or modified resin of phenol resin, epoxy resin, unsaturated polyester resin, and the component may use electric parts such as capacitor, diode, transistor, filter, rectifier, resistor, coil, IC or all electronic parts. Thus, the marking property and the identification function after marking are improved to provide excellent marking method of the resin-sealed electronic component.</p> |
