Lead Free HAL PCB Assembly
Lead Free HAL PCB Assembly

Lead free is restrictly controlled in electronics which are sold in Europe and America countries.The RoHS (Restriction of Hazardous Substances) directive does not allow the usage of six hazardous materials from use in electronic and electrical equipment manufacturing. Lead, which is used in Printed Circuit Board (PCB) manufacturing is one of the materials among the six. With this in mind, MOKOPCB offers lead-free pcb assembly (Pb-Free) and RoHS-compliant circuit board assemblies.  We’ve been manufacturing RoHS compliant circuit boards with over 15 years and know how to successfully convert your Bill of Materials by suggesting alternative parts that are RoHS compliant.  During the surface finish stage of PCB manufacturing, our engineers follow strict operation guides of lead free finishes, such as Solder Finish (lead free HASL), Electroless Nickel Immersion Gold (ENIG), Electroplated Nickel and Soft (bondable) and Hard Gold, Immersion Silver, Immersion Tin (White Tin), Organic Solderability Preservatives (OSP).This means that in our PCBs, we exclude materials such as:

  • PCDE (Polybrominated dephenyl ether) compounds
  • Cadmium and its compounds
  • PBB (Polybrominated biphenyl) compounds
  • Hexavalent chromium compounds
  • Mercury and its compounds
  • Lead and its compounds

Lead-free PCB Benefits

Owing to the following benefits, a lead-free PCB is preferred over the leaded one:

  • Good Thermal Properties: Generally, a lead-free PCB has the capability to survive about 2000 thermal shocks that can vary from -45°C to 145°C. We use the UL approved laminates for our lead-free PCB designs. These laminates can survive temperatures more than 260°C.
  • Low Carbon Footprint: Along with the RoHS regulations, the lead-free PCBs also follow the directive of Waste Electrical and Electronic Equipment (WEEE). This not only helps reduce its effect on the environment, but also reduce the carbon footprint immensely.

Industries Served

With the capabilities mentioned in the table above, it has helped us to serve a wide range of industries varying from Aerospace and Satellite, LED, Medical industries, to wireless, military, and telecommunications industries.

We absolutely comply with RoHS directives to offer lead-free copperplates, lead-free PCB manufacturing process, lead-free PCB assembly. We don’t want to see our customers falling into trouble due to their products containing Pb. As a PCB manufacturer, this is commitment of all our staff.
