Let us begin with a brief introduction to RoHS compliance before we delve into the aspects that one must know about RoHS compliant circuit boards.
The Restriction of Hazardous Substances Compliance, popularly known as RoHS or Directive 2002/95/EC, are a set of standards that restrict the use of hazardous and toxic materials in electronic products sold or distributed in the European Union.
Any OEM (Original Equipment Manufacturer) who manufacturers and sells electronic products or components such as printed circuit boards (PCBs) directly to European clients or support the EU-based integrators, distributors, and resellers need to adhere to this compliance.
The compliance specifies some restricted material as also the maximum levels of these restricted materials in the PCBs and other electronics items as under:
There are 3 key concepts that are basic to RoHS-compliant PCB manufacturing:
The first thing to know when it comes to a RoHS-compliant PCB is the use of material. It is critical that the materials used in the assembly of the board are RoHS compliant, in accordance to the regulation. This also includes paying attention to using RoHS compliant substrate materials, lead-free surface finishes, lead free wave soldering and other such services.
The most widely used surface finishes when it comes to lead free boards include:
Each of them, of course, comes with their own distinct set of advantages and disadvantages.
Other than the use of PCB Materials, it is important to have the correct processes in place. Such processes can go a long way in keeping RoHS & non-RoHS material separate.
The materials as well as the processes need to be documented correctly so as to show that your PCB meets the regulatory requirements.
Some of the major benefits of RoHS-Compliant PCBs include:
With obsolescence in technology growing at an alarming rate, so is electronic equipment that is finding place in landfills. Made up of various hazardous materials, that they impact the environment is a given. With the RoHS directive, the impact on both the environment and hence the people is going to be contained. What we will definitely get is a greener environment.
With electronics manufacturers following the RoHS compliance, what users get are non-hazardous products that are safe to use.
Lead-free PCBs have improved thermal properties. Typically they can withstand temperatures between -45°C to 145°C. In fact, with the use of halogen-free laminates the thermal stability can be improved up to 300 degree Centigrade.
Typically the following details will tell the manufacturer that you are looking for RoHS compliant boards:
Checkout the following steps are involved for RoHS certification:
To sum up
RoHS compliant PCBs can go a long way towards creating a green future. It is therefore important to approach a trust RoHS complaint PCB partner that offers reliable products.
