Why you need RoHS Compliant PCB Assembly service?
Human are increasingly faced with environmental issues and concerns about hazardous materials.
To combat this issue, new regulations have been established. One of these regulations is RoHS compliance, or the Restriction of Hazardous Substances.
In the EU, manufacturers are required to adhere to the Restriction of Hazardous Substances (RoHS) directive, which came into effect in July 2006. This regulation prohibits the use of six substances in electrical and electronic products. It specifies maximum concentration levels for each material. Pursuing RoHS-compliant PCB manufacturing is to ensure that the electronics components are environmentally friendly.
These regulations are designed to improve the safety and performance of electronics products while minimizing the impact on the environment. Choosing a RoHS compliant PCB assembly manufacturer is critical for many reasons.
Non-compliance will ultimately result in lower sales and a reduced customer base. In addition, businesses based outside the EU may be required to follow RoHS regulations in order to sell their electronic products to European distributors and resellers. By adhering to RoHS guidelines, they will be able to demonstrate quality manufacturing to their clients.
How to select a RoHS Compliant PCB Assembly manufacturer?
To make PCBs compliant with the RoHS directive, the PCB Assembly manufacturer must use materials that are free of hazardous substances. Lead was once widely used in electronics manufacturing, but the directive has banned its use in electronics manufacturing. Manufacturers must avoid lead-based solder, which is highly toxic to both humans and wildlife. Fortunately, lead-free soldering is an easy process to adopt.
Manufacturers can benefit from RoHS compliance by making sure all discrete components, solder joints, and heat sinks comply with these regulations.
PCB manufacturers must train their staff in the appropriate practices and requirements to meet RoHS requirements. This training should include inventory control, solder chemistry, manufacturing processes, rework, inspection, and more. CMs should have extensive experience building PCBs to RoHS specifications and must have the capability to transition legacy designs to RoHS-compliant models. They should also have engineering capabilities to help customers transition from their old designs.
RoHS compliance requires higher processing temperatures. Process margins are smaller for lead-free and RoHS compliant circuit boards. To ensure RoHS compliance, manufacturers must use thermal profiling equipment.
Thermal profiling is based on a number of factors, including board thickness, finish, and layer count. Some reflow soldering tools are specifically designed to track thermal profiles and make them more accurate.
