RoHS Compliant PCB Assembly with Tempo Automation

Over the past few decades, the application of electronics and the circuit boards that drive them expanded into virtually all industries. This has resulted in more functional, capable, and safer products with improved process efficiency for board fabrication and PCB assembly. The impetus to build safer boards emerged because of the increase in electronics-based medical device utilization, as well as a better understanding of which materials and substances pose a risk to end users. The latter is the catalyst for RoHS compliant PCB assembly.

Indication of compliance with the RoHS directive

What is the RoHS Directive?

The Restriction of Hazardous Substances (RoHS) Directive was first enacted in 1995. The European Union issued this initiative to curtail the risk of public harm from the use of electronic products. Initially, six restrictive substances made the list; however, the third recast of the initiative, Directive 2015/863, increased that number to ten (listed below).

RoHS Restricted Substances

Benzyl butyl phthalate (BBP)

Bis (2-Ethylhexyl) phthalate (DEHP)

Cadmium (Cd)

Dibutyl phthalate (DBP)

Diisobutyl phthalate (DIBP)

Hexavalent Chromium (Cr VI)

Lead (Pb)

Mercury (Hg)

Polybrominated Biphenyls (PBB)

Polybrominated Diphenyl Ethers (PBDE)

The limitation on the presence of the above substances is < 1000 ppm, except for cadmium. This highly toxic substance must be < 100 ppm.

Who is Impacted by the RoHS Directive?

To maximize the effectiveness of this safety protocol, compliance with the RoHS Directive extends to all entities involved in the electronics supply chain. This includes manufacturers, sellers, and distributors of any electrical and/or electronic components, sub-assemblies, cables, products, equipment, or parts for replacement that are intended for utilization in RoHS-directed countries.

Although the institution of the RoHS standard originated in the EU, today this safety regulation is spreading throughout the world. For example, the following territories also impose RoHS restrictions.

The reach of RoHS compliance is ever-increasing, which is why a RoHS compliant PCB assembly is essentially required today.

Tempo’s RoHS Compliant PCB Assembly Process

At Tempo Automation, we provide full turnkey PCBA manufacturing faster than anyone in the industry. As a contract manufacturer in Silicon Valley, our assembly processes are compliant with all pertinent RoHS regulations.

This includes sourcing from the most reliable component suppliers who provide detailed and traceable information, such as RoHS adherence.

If your design calls for lead-free soldering, we will work closely with you to ensure that higher temperature requirements pose no risk to your components, board quality, or structural integrity.

And to help you get started on the best path, we furnish information for your DFM checks and enable you to easily view and download DRC files. If you’re an Altium Designer or Cadence Allegro user, you can simply add these files to your PCB design software. For Mentor Pads or other design packages, we furnish DRC information in other CAD formats and Excel.

Tempo’s PCB Assembly process options

Tempo’s digital thread manufacturing process leads the on-demand PCBA industry in building custom and complex boards fast and precisely. Working with us is a symbiotic partnership focused on delivering PCBAs that meet your schedules and high-quality standards.
