RoHS Compliance for Environmental Safety
RoHS compliant PCBs are specifically designed for the safety of our environment. Maintaining the green future is the greatest benefit of these PCBs.
User Safety
A RoHS compliant guarantees the safety of users. Most PCB manufacturers adopt RoHS compliance. Поэтому, users are guaranteed that the product they utilize contains no mercury or lead. Также, this has tremendously increased the popularity and sales of the products.
Enhanced Thermal Properties
Lead-free circuit boards feature great thermal properties. Поэтому, they perform better than their leaded counterparts. These circuit boards can resist temperatures between -45°C to 150°C. These days, manufacturers are making use of halogen-free materials that have improved thermal stability.
Reduction of Metal Poisoning
Electronic consumers are discarding obsolete electronic devices in landfills. Также, these devices feature hazardous materials which can result in severe poisoning. Despite recycling, these devices feature harmful substances in them. Также, the RoHS has compelled OEMs to minimize the use of hazardous substances. This has reduced the effect of these materials on the environment.
Product Reliability
Most popular electronics manufacturers adopt the RoHS directive. Также, customers are now guaranteed of the reliability and safety of products. Поэтому, this has helped to improve the reputation of brands that produce RoHS compliant circuit boards.
Improved Testing Methods
RoHS compliant circuit boards pass through improved testing methods. Также, RoHS PCBs use lead-free solder finish. Chemistry methods and spectroscopy are two common methods used by RoHS. These methods determine the concentrations of restricted substances.
Applications of RoHS Compliant PCB
RoHS compliant PCB is widely used in several applications. Environmental safety has become a major concern for most industries. Также, the electronic industry has sought ways to make electronic devices more environmentally friendly. Поэтому, RoHS compliant boards offer a lasting solution to this challenge.
Медицинский
RoHS compliant PCBs are widely used in the medical industry. Также, medical devices require the use of safe PCBs. The restriction of specific hazardous materials is applicable to medical devices. Также, these circuit boards are useful for producing safety-critical devices. The directive 93/42/EEC is a requirement for medical devices.
Telecommunications
RoHS compliant circuit boards are available in telecommunication devices. These boards have helped to prevent environmental-related risks.
Бытовая электроника
The RoHS directive stresses the need for the use of RoHS compliant PCB in consumer electronics. Поэтому, consumer electronics like televisions and mobile phones feature lead-free PCBs. These lead-free PCBs are safe for the environment.
RoHS Compliant Surface Finishes
Not all PCB surface finishes are RoHS compliant. A RoHS PCB must be completely free from any hazardous materials listed by the RoHS directives. Lead-free finishes add to the physical capabilities of PCBs. Some PCB surface finishes are RoHS compliant. These surface finishes include:
Погружная банка
Immersion tin is a lead-free PCB surface finish. Поэтому, it is RoHS compliant. Также, this lead-free surface finish is suitable for fine pitch components. The immersion tin is a deposit of a layer of tin. Поэтому, immersion tin serves as a great alternative to lead-based finishes.
Immersion Silver
This is another popular lead-free PCB surface finish. Immersion silver offers EMI shielding. Также, immersion silver is ideal for membrane switches and aluminum wire bonding.
ОСП
Organic solderability preservatives (ОСП) surface finish has gained popularity over the years. This is because of its interest in lead-free processes. Также, OSP produces a thin and protective layer on the copper surface of circuit boards. This layer shields the circuitry from any oxidation during PCB assembly.

Electroless nickel immersion gold is another lead-free surface finish. ENIG features two main layers of metallic coating which are electroless nickel and immersion gold. Также, ENIG is RoHS compliant since it features no lead. Поэтому, ENIG is a highly preferred surface finish among PCB manufacturers.
Lead-free HASL
Lead-free HASL complies with the RoHS directives. Unlike leaded HASL, lead-free HASL comprises no lead. This surface finish option offers excellent solderability and shelf life. Также, it is ideal for lead-free soldering.
ENEPIG
Electroless nickel electroless palladium immersion gold (ENEPIG) is a lead-free PCB surface finish. Также, this surface finish features nickel, palladium, and gold. The palladium layer shields the nickel layer from any corrosion. ENEPIG is more affordable than ENIG since it doesn’t comprise gold.
