RoHS PCB Assembly

Today’s manufacturers of PCB Assembly have been increasingly contending with, is the rising concerns about the use of hazardous materials as well as the environmental impact that accrues on account of it. It isn’t surprising therefore all over the world, new and stringent regulations are being imposed to deal with this growing issue. One such important legislation is to do with the Restriction of Hazardous substances or RoHS compliance.

If you are keen to know what exactly does this compliance entail and importantly what are its benefits, then you are at the right place. Read on for the complete details:

What is RoHS Compliant?

The RoHS compliance is the European union’s directive 2022/95/EC that came into effect as of July 1, 2006, to prohibit the use of hazardous substances in electronic production. What it means is that if you sell any electronic products or PCBs in the European Union, you need to adhere to this regulation.

To be RoHS compliant as a manufacturer, the use of the following 6 materials in PCBs and other electronic items, have been restricted.

rohs restricted substances
  • Mercury
  • Lead
  • Cadmium
  • Hexavalent Chromium
  • Polybrominated Diphenyl Ethers
  • Polybrominated Biphenyls and Phthalates

The maximum levels of these restricted material are also specified in the regulation. The limits are as below.

  • Mercury should not be more than 100 ppm
  • When it comes to Lead, the limit is 1000 ppm
  • For Cadmium it is 100 ppm
  • Polybrominated Biphenyls are restricted at 1000 ppm
  • For Hexavalent Chromium, the limit is again set at 1000 ppm
  • Polybrominated Diphenyl Ethers are set at 1000 ppm
  • For Phthalates also the limit is 1000 ppm

When you have a RoHS compliant PCB Assembly, you can offer a whole lot of services that are distinct from others. Some of the main distinguishing features of such a PCB Assembly include:

  • Lead-free surface finishes
  • RoHS compliant substrate materials such as S410, Polyclad 370HR. These, in turn, assure standard performance
  • Primary and secondary services such as lead trimming

Benefits of RoHS Compliance

The important bit, is also to know what are the benefits that accrue from having a RoHS complaint PCB Assembly. Some of these include:

Benefits of RoHS Compliance

Environmental Impact

The big advantage of a RoHS PCB Assembly, is to do with its environmental impact. With obsolete electronic equipment being thrown in landfills, they have a devastating impact on the environment. With restrictions being put on the use of hazardous substances in case of RoHS compliant assemblies, the impact on the environment is significantly stymied.

Safety for users

Users can now be secure in the knowledge that the product they are using is being manufactured in an RoHS compliant PCB assembly and therefore is lead and mercury free.

Thermal stability

What also follows from lead free PCBs is improved thermal stability. In fact, with halogen free laminates the thermal stability can go up to as much as 300 degree Centigrade.

Improved sales for manufacturers

The improved safety of the product, in turn, also leads to improved sales for the manufacturer. By not complying with the RoHS regulations, on the other hand, you will significantly reduce your customer pool. Not only is RoHS compliance required to sell in the European Union, it is also needed to sell to resellers and distributors who sell in these countries.

In choosing a PCB Assembly Service that is RoHS compliant, you tend to reap the following advantages:

  • Have a compliance strategy in place for your products
  • Have a large customer base with the ability to supply to EU countries
  • Gain customer trust
  • Contribute to a green environment
