What is RoHS?
The electronics industry usually uses several kinds of hazardous substances in the productions, such as lead (Pb), Mercury (Hg), Cadmium (Cd), Chromium (Cr6+), Polybrominated Biphenyls (PBBs), and Polybrominated Diphenyl Ethers (PEDEs). These substances are incredibly harmful to the environment and human health.
RoHS refers to the restriction of hazardous substances. It is an EU Directive that restricts the use of materials that include the aforementioned dangerous substances in PCB manufacturing. The RoHS directive takes effect on July 1, 2006, and authorizes EU member states to reject electronic and electrical products containing more than the specified amount of the above-mentioned harmful substances.
What is the RoHS-lead free in PCB manufacturing?
Since people are aware of the environmental and physical hazards of these toxic substances, PCB manufacturers are working to eliminate such substances in the manufacturing process. Among these RoHS-banned harmful substances, lead is the only one that is widely used in the integrated circuits to reduce costs and improve efficiency. For PCB manufacturing, RoHS requires the PCB assembly manufacturers to ensure that the hazardous substances specified in the directive are not used in any assembly process, including boards, welds, and components.
Generally, lead-free PCB manufacturing includes lead-free materials, lead-free components, and lead-free solder technology. To meet RoHS standards and environmental protection requirements, the popularity of lead-free PCB products has gradually increased in the integrated circuit industry.
But we need to know that RoHS is not a quality standard, RoHS or lead-free just means different manufacturing method and soldering process. Both lead products and lead-free products can satisfy your performance requirements. Another advantage of lead-free manufacturing is that the components and solder paste with unleaded have no danger to the workers. The lead-free standard helps to provide safety manufacturing environment for the workers and safety products for the users.
RoHS-lead free process at PCBGOGO
As a lead-free PCB assembly manufacturer, PCBGOGO provides lead-free surface finishes that comply with the RoHS standard. The lead-free plating finishes are available: lead-free HASL, ENIG, OSP, etc. And we can provide lead-free soldering for smaller and tighter PCBs much cheaper and faster. We ensure the reliability of our PCB products through a series of lead-free technologies, such as electroplating technology, solder ball formation technology, and solder dipping technology. The requirement of RoHS-lead free increases our competence in the global environment.
PCBGOGO is one of the leading RoHS compliant PCB assembly manufacturers in China. We play an active role in eliminating harmful substances in electronic products by providing PCB manufacturing and PCB assembly prototype services that comply with RoHS regulations.
