Proud to Be a Lead-Free PCB Assembly Provider

There is a very good reason why the United States no longer allows lead in paint, plumbing, gasoline, toys, and many household products. Although lead is naturally occurring, it is also a highly toxic metal with serious health consequences. Research has linked lead exposure to behavior and learning difficulties, reduced IQ, slowed growth, anemia, cardiovascular problems, and, in extreme cases, coma or death. Children and pregnant women are especially vulnerable, and even minimal exposure can create long-term neurological and developmental harm.

For many years, lead was widely used in the electronics industry—particularly in soldering printed circuit boards (PCBs). Tin-lead solder was reliable, affordable, and easy to work with, which helped make it the long-standing industry standard. However, as global awareness of lead’s dangers increased, regulators and manufacturers began transitioning toward safer, more environmentally responsible lead-free alternatives.

At ACME PCB Assembly, we are proud to be part of this movement. Our full commitment to lead-free PCB assembly ensures a safer environment for employees and a safer end product for our customers. Switching to lead-free soldering is much more complex than simply changing materials. Lead-free solders melt at higher temperatures, which affects the entire assembly process, equipment requirements, and inspection standards.

Printed Circuit Board FabricationTo meet these demands, we invested in upgraded machinery, re-engineered our soldering and reflow processes, and strengthened temperature control systems to ensure long-term reliability. Just as important, our technicians underwent extensive retraining to understand the different properties, behaviors, and inspection details of lead-free solders. This comprehensive approach allows us to maintain exceptional quality while eliminating a major health and environmental hazard.

Although the transition required time, investment, and new expertise, it was absolutely worth it. Removing lead from our operations gives us a cleaner, healthier workplace and aligns our manufacturing processes with global standards such as RoHS (Restriction of Hazardous Substances). It also gives our customers confidence that their boards are produced using safe, compliant, and environmentally conscious materials.

Today, ACME PCB Assembly proudly operates as a fully lead-free PCB assembly provider, delivering high-quality, reliable PCBs for industries that demand safety, consistency, and performance. Whether you need prototypes, short production runs, or full-volume assembly, you can count on us to deliver the best results using trusted lead-free technology.

How Being RoHS-Compliant PCB Assembly Services are Different from Assembly Services?

With everyone’s increasing concerns on the over usage of hazardous materials in the electronic and electrical products and their environmental impact, there have been several stricter regulations being imposed by the leading governmental organizations across the world. The RoHS compliance is one of those important regulations that is currently being imposed on the utilization of hazardous materials in the electronics and electrical products. Are you interested in knowing how this compliance works or what the benefits are?

Being Able to Understand the Materials that are Restricted Under RoHS Compliance

The RoHS compliance has restricted the use of six materials in the PCBs and electronic items. They include Mercury (Hg), Lead (Pb), Cadmium (Cd), Hexavalent Chromium (CrVI), polybrominated diphenyl ethers (PBDE), Polybrominated biphenyls (PBB), and phthalates such as BBP, DEHP, BBP, and DIBP.

The compliance also specifies the maximum levels of these restricted materials in the PCBs and other electronics items.

  1. Mercury (Hg): < 100 ppm
  2. Lead (Pb): < 1000 ppm
  3. Cadmium (Cd): < 100 ppm
  4. Polybrominated Biphenyls (PBB): < 1000 ppm
  5. Hexavalent Chromium: (Cr VI) < 1000 ppm
  6. Polybrominated Diphenyl Ethers (PBDE): < 1000 ppm
  7. Bis(2-Ethylhexyl) phthalate (DEHP): < 1000 ppm
  8. Dibutyl phthalate (DBP): < 1000 ppm
  9. Diisobutyl phthalate (DIBP): < 1000 ppm
  10. Benzyl butyl phthalate (BBP): < 1000 ppm

The Many Features of RoHS-Compliant Assembly Services

Many PCB assembly services are utilizing processes and technologies that help them manufacture RoHS-compliant PCB assemblies. The following are a few features that help distinguish these services from others.

  • Lead-free Surface Finishes:Many manufacturers are nowadays using lead-free surface finishes such as lead-free HASL, ENIG, Electroplated Nickel and Soft (Bondable), Hard Gold Immersion Tin (White Tin), and Organic Solderability Preservatives (OSP).
  • RoHS Compliant Substrate Materials:The choice of RoHS material depends on the requirement of the application. There are materials such as Isola IS410, and Polyclad 370HR that assure standard electrical performance; however, materials such as Isola FR415 and Polyclad Getek assure high electrical performance at low loss.
  • Primary and Secondary Services:It has been observed that many RoHS PCB assembly service providers specialized in primary and secondary services such as lead trimming, lead-free wave soldering, and many more.

Some Benefits of Using RoHS-Compliant PCBs

The benefits that are offered by lead-free and RoHS-compliant PCBs are various. The following are a few of them:

  • Helps Reduce Metal Poisoning:As the technology landscape is fast evolving, many customers are discarding their obsolete electronic equipment in landfills. Equipped with various hazardous materials, this equipment helped lead to severe poisoning. Although recycling is being performed, still the equipment may have hazardous substances in them. The RoHS directive has forced OEMs reduce their dependence on hazardous substances. This has helped reduce the impact of these materials on the environment, and people working with them.
  • Improved Product Safety:With RoHS compliance being adopted by many prominent electronics manufacturers in EU and the US, now users can be assured that the product they are using is lead and mercury free. As a result, the sales and popularity of the products from these manufacturers has tremendously increased.
  • Improved Thermal Properties:It is proven that lead-free PCBs have excellent thermal properties than their leaded counterparts. They can easily withstand temperatures between -45°C to 145°C. Nowadays, PCB manufacturers are using specialized halogen-free laminates that have further helped improve their thermal stability up to 300 °C.

The benefits of RoHS-compliant PCBs symbolize a green future.  It is important that you find a trusted RoHS-compliant assembly services provider such as Yun Industrial and ACME PCB Assembly. Our company follows processes that are audited regularly and certified as chemical free.
