Lead Free PCB Assembly

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, Creative Hi-Tech designs and manufactures lead-free PCBs. 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 Capabilities

With the directive in action, we focus on implementing lead-free PCB assembly technologies, and processes to manufacture RoHS compliance PCBs. Advanced equipment used in our processes play a vital role in producing the best results. We also provide services in migrating our customers from leaded to lead-free PCB designs. Our capabilities include:

Material	RoHS-compliant FR-4
Surface Finishes	Lead-free Solder Finish (lead-free HASL) Electroless Nickel Immersion Gold (ENIG)
	Immersion Silver
	Electroplated Nickel and Soft (bondable) and Hard Gold Immersion Tin (White Tin)
	Organic Solderability Preservatives (OSP)
Services	Lead trimming system
	Lead-free wave soldering
	Lead-free compatible reflow systems
Thermal Mass Assembly Reflow	Low: 240°C –245°C High: 260°C

Lead-free PCB Assembly Process

Our lead-free PCB assembly process includes following steps:

Profiling
Inspection
Bill of Materials (BOM)
Application of Board Stensil and Solder Paste
Placement of Components
Through Hole and Manual Solder
Placing Board in Reflow Oven
Testing Packaging

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.

Benefits of Large Volume Printed Circuit Board Assembly Services

Our mass production expertise and capabilities can provide a variety of benefits to customers.We utilize automated pick and place machines for the assembly process. Due to this, we can assemble bulk PCBs within a short time period.

All of our PCBs undergo rigorous AOI, ICT, and X-ray testing and inspection. We ensure that our PCBs meet all application and industry requirements, in terms of speed, performance, and regulations.
By choosing large volume orders, customers can save on their overall costs.
We design our prototypes with the same level of quality as the final assemblies. This ensure that the final PCBs delivered to customers will be performance driven and durable.
We ensure that all the PCBs meet exact design and production requirements. This provides assurance in terms of accuracy and consistency.

Be it standard or custom requirements, CHTL can take on any large volume PCB assembly orders. We ensure to deliver all the products on time and of the best quality. Please contact us for more information about our large volume printed circuit board assembly services.
