How to Label Electrical Components with a Laser

Using a Laser Marking System to Label Electronics

Typically, manufacturers need to label electrical components with a variety of information. The items are often very delicate and small, requiring special care and specific equipment. Laser marking systems are a great way to achieve permanent labeling on silicon, plastic, metal, and other materials. Electrical components use a very wide range of materials from high temperature plastics to most metals. Lasers can cover this full range of materials and can give a range of different marks depending on the settings and type of laser.

Laser is Better than Ink

Ink marking is temporary, messy, and antiquated. Laser engraving/marking is permanent, clean, and modern. An added benefit to utilizing lasers is that you can eliminate the use of costly consumables that inkjet requires— like ink supplies. Laser marking systems are also specially designed to fit industry needs. In the electronics industry, Ultraviolet laser marking systems are the equipment of choice because it can apply a mark without any heat, protecting the integrity of the part. You can use a UV laser on printed circuit boards (PCB), where the laser mark even becomes resistant to solder.

Types of Marks that Lasers Can Make

Electronics may require 2D matrix codes, company logos, assembly information, customer instructions, or other content. You can achieve every one of these marks by utilizing a laser marking system. Often, you can apply these marks at very high speeds resulting in fast throughput. Some other types of labeling include:

  • Highly detailed schematics that give clear instructions for the user
  • Incredibly small micro-marking to the smallest components (would be impossible to do with ink marking)
  • Precise indicator marks for exact placement – on a flat part or a rounded part’s circumference
  • Even mark wire insulation on the fly as you are fabricating it


Establish Next Generation Quality Control.

Marking every part allows quality control and traceability of your products. With lasers, you can mark parts without physical contact, without disrupting the surface, and with ultimate precision. Telesis lasers have precision that is accurate enough to mark an entire pallet of parts — in the exact location every time.

Other Benefits of Using Lasers

Laser marking provides low-cost, environmentally-friendly marking compared to ink marking. In many cases, the laser is faster, higher quality, more accurate, offers more options, and can have a return on investment in a short period of time.
