Electronic parts require identification and traceability in the form of barcodes, serial numbers to indicate functions, parts numbers, expiration dates, etc. As a result, electronic part manufacturers need to learn about different marking systems and machines available. Aside from that, manufacturers need to understand the properties of the part they are working on, as this plays a huge role in the choice of coding and marking solutions.

Markings in the electronic manufacturing industry can be challenging due to electronics’ wide types, designs, and sizes. However, this article will approach the marking solution from an easy side, such that you can introduce precision coding and marking solutions for your electronics part marking needs.


Marking Solutions for Electronic Parts

Different Sizes

To mark small electronic parts with precision, you need to consider the size and the operation of the available marking machines related to the process. Generally, it would be best to look for a machine that can replicate different markings easily without affecting the precision of the marking process.

As a recommendation, large electronic parts are better marked with portable marking machines as they are easy to maneuver and reach difficult parts. For example, the 20w and 30W handheld machines are portable laser marking machines you can use. Also, inkjet marking machines such as the HS-PT01 can be suitable. However, a bench or rigid machine is more suitable for small parts as it will be more accurate. In the case of an inkjet marking system, an inline marking machine might do the job.

Different Electronic Part Marking Material

The electronic industry uses different materials in its marking process, with the general category being metals and plastics. Both inkjet and laser marking are suitable for different materials, and below are certain distinctions:

Laser marking:

The laser marking machine is suitable for the following:

  • Metallic materials such as copper, tin, and gold that are applicable in making electronic parts. This is achievable primarily using a fiber laser marker such as the HS-FL20.
  • Non-metal materials such as plastics, ceramics, and glass are used in the component or as packaging. This is primarily achievable using a CO2 laser marker such as the HS-CL30.
  • Thermosensitive parts and electronic components can also be marked using a UV laser machine such as the HS-UV03.

Inkjet marking:

Inkjet marking machines are suitable for all materials used in electronic parts. However, it would be best to consider the ink’s reaction to the material.

Different Electronic Components and Parts

Electronic parts come in different parts and sizes. Some critical electronic parts, e.g., the motherboard, require precise markings due to their delicateness. As a result, there are different types of marking systems for such parts. Below are a few things you can consider:

  • Delicate parts: Internal parts such as the motherboard that require permanent and extremely precise markings need laser marking machines. For parts where permanency is not necessary, both marking systems are ideal
  • For outer parts or packaging: Both marking systems suit outer parts or packaging. However, since permanency is not an issue here, the inkjet marking system is better. Moreover, if permanency is needed, consider a laser marking system.

Permanent Markings

Permanent marking, alongside the delicateness of electronic parts, is the basis of the worldwide acceptance of laser and inkjet marking systems in the electronic industry. Laser marking is the right method when looking at the precision and permanency of marking. In other cases, a thermal inkjet marker is appropriate.

Why Not Dot Peen Marking System?

Dot peen marking is unsuitable for electronic parts due to their delicateness and how a dot peen marker works. A dot peen marker prints on a material by striking the material pneumatically or electrically. As a result, many electronic parts cannot withstand force. Furthermore, dot peen marking is less accurate than the recognized method.
