OSP Finish 94v0 PCB Board RoHS Medical PCB Assembly

Importance of RoHS PCB Assembly

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. Therefore, users are guaranteed that the product they utilize contains no mercury or lead. Also, this has tremendously increased the popularity and sales of the products.

Enhanced thermal properties

Lead-free circuit boards feature great thermal properties. Therefore, they perform better than their leaded counterparts. These circuit boards can resist temperatures between -45oC to 150oC. These days, manufacturers are making use of halogen-free materials that have improved thermal stability.

Reduces metal poisoning

Electronic consumers are discarding obsolete electronic devices in landfills. Also, these devices feature hazardous materials which can result in severe poisoning. Despite recycling, these devices feature harmful substance in them. Also, 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 RoHS directive. Also, customers are now guaranteed of the reliability and safety of products. Therefore, this has helped to improve the reputation of brands that produce RoHS compliant circuit boards.

Various improved testing methods

RoHS compliant circuit boards pass through improved testing methods. Also, RoHS PCBs use lead-free solder finish. Chemistry methods and spectroscopy are two common methods used by RoHS. These method 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. Also, the electronic industry has sought for ways to make electronic devices more environmentally friendly. Therefore, RoHS compliant boards offer a lasting solution to this challenge.

Medical

RoHS compliant PCBs are widely used in the medical industry. Also, medical devices require the use of safe PCBs. The restriction of specific hazardous materials is applicable to medical devices. Also, 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.

Consumer electronics

The RoHS directive stresses the need for the use of RoHS compliant PCB in consumer electronics. Therefore, 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 finished add to the physical capabilities of PCBs. Some PCB surface finishes are RoHS compliant. These surface finishes include:

Immersion tin

Immersion tin is a lead free PCB surface finish. Therefore it is RoHS compliant. Also, this lead-free surface finish is suitable for fine pitch components. The immersion tin is a deposit if a layer of tin. Therefore, 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. Also, immersion silver is ideal for membrane switches and aluminum wire bonding.

OSP

Organic solderability preservatives (OSP) surface finish has gained popularity over the years. This is because of its interest in lead-free processes. Also, 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.

ENIG

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. Also, ENIG is RoHS compliant since it features no lead. Therefore, 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. Also, it is ideal for lead-free soldering.

ENEPIG

Electroless nickel electroless palladium immersion gold (ENEPIG) is a lead-free PCB surface finish. Also, 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.
