Everyone in the PCB industry is familiar with ROHS compliant PCB manufacturing. The term ROHS stands for Restriction of Hazardous Substance Directive. In 2002, the European Union has introduced a Directive 2002/95/EC, under which the use of six hazardous substances including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl, and polybrominated diphenyl ether is prohibited. This directive focuses on a nature-friendly production of electrical and electronic components. The traditional PCB manufacturing makes use of many of these prohibited substances, mainly the lead. Therefore, to manufacture RoHS compliant PCBs, the manufacturer would require a user and nature-friendly alternatives of prohibited substances. The demand for ROHS compliant PCBs is more in the European Union countries. So, the manufacturers supplying to these countries need to adhere to this compliance.
The PCB manufacturing up to 4-layers is considered to be a convenient task in the PCB industry. However, if these requirements raise up to 20 layers, then the PCB design and manufacturing becomes a little tricky. Since the PCB manufacturing is a layer-focused process, the 1-20 layers PCB manufacturing falls under the category of complex multilayer PCBs. This multilayer PCBs can be designed under different criteria.
If designed according to RoHS standards, then there are lots of considerations involved. One of the most common challenges of RoHS compliance PCB 1-20 layers assembly is that the PCB easily catches moisture and loses strength in soldering due to no lead composition. Therefore, to overcome such challenges RoHS compliance PCB 1-20 layers assembly utilizes the following materials:
As the resource requirements for RoHS compliance PCB 1-20 layers manufacturing are well introduced in the above section. It is now important to partner with an experienced PCB manufacturer. Twisted Traces is one of the leading manufacturers of RoHS compliant PCBs in the US. They have been providing these lead-free PCBs for several years and they are capable of manufacturing ROHS compliance PCBS 1-20 layers.
