RoHS Compliant PCB

The electronics industry is one such industry that make use of several types of hazardous substances in the production of varied electronic and electrical equipment. The materials such as Lead (Pb), Mercury (Hg), Cadmium (Cd), Hexavalent Chromium (Cr6+), Polybrominated Biphenyls (PBB) and Polybrominated diphenyl ether (PBDE) are extremely dangerous to the environment, as well as to the people. Due to the alarming rate of environmental pollution from such inadequately treated e-waste, Restriction of Hazardous Substances (RoHS) EU Directive (2015/863) has strictly banned the use of the materials aforementioned in PCB manufacturing.

Realizing the environmental threat they bring, the electronics manufacturing industry is in the process of eliminating such perilous substances in the fabrication process, and we at Twisted Traces are proud to say that we are one amongst the leading RoHS compliant PCB manufacturers in the US. We ensure to provide PCB fabrication and assembly services conforming to RoHS regulations and thus taking an active role in eliminating hazardous substances from electronic products.

RoHS-compliant PCB design and Assembly Capabilities at Twisted Traces

As a part of RoHS-compliant PCB design services, we focus on implementing lead-free PCB assembly technologies, and processes that meet the requirements of RoHS. We, at Twisted Traces, own the capabilities to design and assemble both standard and customized boards as per the RoHS Directive. Being a RoHS-compliant PCB design Services provider, we guarantee the following when it comes to lead-free board assembly.

  • We ensure using lead-free materials like IS410 or R370HR, FR-4 during the PCB assembly. We have a close association with vendors who assure the timely supply of the finest quality materials meeting the requirements of RoHS. We also ensure that the parts and components we source from these vendors are free from hazardous chemicals.
  • The laminates we use for lead-free assembly are known for their higher Td to withstand the increased temperature beyond 260°C. They also withstand long duration assembly cycle as required in the case of some lead-free assembly projects.
  • As a renowned lead free PCB manufacturer, we ensure to use lead-free finishes that are RoHS compatible. The following are the plating finishes options available for lead-free assembly at Twisted Traces.
    • Solder Finish (lead free HASL)
    • Electroless Nickel Immersion Gold (ENIG)
    • Electrolytic Nickel/Gold - Ni/Au (Hard/Soft Gold)
    • Immersion Silver, Immersion Tin (White Tin)
    • Organic Solderability Preservatives (OSP)
  • At Twisted Traces, we use lead-free solder with a 96.5% tin, 3.0% silver, and 0.5% copper alloy, among others. Being lead-free, the components and solder paste do not pose any danger to the workers even if they come in contact with a person. Thus, in a way, lead-free PCBs help maintain the safety of workers.
  • Our manufacturing processes and techniques employed are checked periodically to guarantee RoHS compliant PCB assembly. Also, we ensure providing our employees with timely training and certification regarding RoHS directives.
