Lead-Free PCB Assembly Services

A new EU directive came into force on July 1st 2006. It is referred to as "RoHS" This stands for "the restriction of the use of certain hazardous substances in electrical and electronic equipment".

From July 1st every PCB assembly put on the market in the EU must be Lead-Free unless special exclusions apply. The Lead-Free PCB assembly process requires machines that operate with more precise control over temperature. This is because Lead-Free solders melt at higher temperatures.

The temperature required for Lead-Free is potentially problematic for some plastic components. So when using Lead-Free solders, the temperature 'operating window' needs to be more precisely controlled. Most pre Lead-Free machines are not up to the job. Generally speaking, one can't just turn up the temperature on an older machine in order to produce a Lead-Free PCB assembly. This would likely cause problems with connectors and other plastic parts or would risk low quality Lead-Free joints.

TS has been preparing for Lead-Free PCB assembly for several years, and by February of 2006, TS had a new production line especially geared up for Lead-Free PCB assembly. So we've been working with Lead-Free and sourcing Lead-Free parts for some time.

RoHS and PCB Assembly

Lead-Free is the better-known requirement of RoHS. There are other requirements that affect PCB assembly. In order to help the environment, the EU is also banning the following substances. Cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) flame retardants.

This affects fasteners, relays and switches, cables, paints, plastics and other components that may be used in PCB assembly.

These changes represent a great challenge to the industry. Everyone involved with PCB assembly needs procedures of ISO quality in order to navigate these new requirements.

At the end of the day, it's your product that needs to comply. We'll work with you to ensure compliance.

Production Machines for Lead-Free SMT and Through-Hole PCB Assembly

Lead-Free PCB Assembly requires more accurate control of temperature.

TS invested in a new Lead-Free production line so as to be RoHS compliant well before this became a legal requirement for PCB assembly services.
