Manufacturing, Assembly, Product Box Builds

Manufacturing and AssemblyFlexible Circuit Technologies’ core business is flexible circuit design and production which is aimed at providing our customers with high quality production parts at competitive prices. From small to high volume programs, we are set up to meet your bare flex/rigid flex/flexible heater needs and further; your circuit assembly, product module to complete product box build.

Circuit Manufacturing

FCT’s four Flex Facilities include a 60,000 square foot facility in Jiangmen, China, a 150,000 square foot facility in Xiamen, China, 170,000 sq. foot facility in Zhangzhou, China and our 375,000 sq. foot facility in Zhuhai China; allowing us to offer significant capacity and broad capabilities to meet customer needs.

Our organizational structure, inclusive of multiple production facilities; allows us to be extremely flexible whereby we support customers with low volume needs (100 circuits EAU) to those that have extremely high-volume needs (100 million EAU). 

Unless specified by our customers, FCT most often utilizes IPC approved, Asia equivalent materials that helps our customers to attain excellent savings while not giving up on performance.  We also utilize customer specified materials when/if needed.

Given our superior expertise in design, FCT aims to develop solutions where we will attain high yields for our customers that lead to improved overall costs. 

EMS/Assembly Services

FCT’s ASIA based headquarters is located in Shenzhen, China. This 85,000 square foot facility is home to our China based Management team, Program Managers, Customer Support staff, and world class Assembly facility.

Our assembly facility offers:

  • Seven complete SMT lines
  • 100K and 10K Clean Rooms
  • 9 modern Electronic Workshops
  • Reliability Lab
  • Testing Services
  • Dedicated workshops for specific customers in support of meeting high-volume programs and dedicated workshops that are set up for high mix - lower volume programs.

Assembly Capabilities Include:

  • Full SMT lines
  • Leading expertise in placement of components onto flex
  • Hot-Bar soldering
  • BGA Assembly - smallest pitch .25mm
  • 01005 or above - component placement
  • Selective Wave Solder
  • ACF/ACP bonding (anisotropic conductive film or paste bonding)
  • Wire Harness - added to circuit assembly
  • Sonic welding or other attachment methods and much more…
  • FCT will also design and procure specialized equipment to support overall program requirements if/as needed and more…

Today, above 65% of the products that we produce are circuit assemblies; whereby we are placing components onto the flex/rigid flex/flex heaters that we produce and/or taking the product further in producing a product module or complete product box build.  

FCT is one of the most proficient "assembly on flex" companies on the globe, offering years of proven expertise.

Why more customers are utilizing FCT's assembly services…

FCT maximizes value in providing cost effective assemblies to our customers. 

  • We provide overall program management inclusive of procuring and managing the components and overall supply chain.
  • If we are already building your circuit, it would make great sense to simply have us perform your Assembly service.
  • Panelization - FCT maximizes the number of circuits per panel to assure we maximize material costs and have as little waste of material as possible, leading to lower overall circuit cost.
  • We do not place unrealistic x-out requirements on our panels that lead to higher costs for the end customer; something that outside assembly shops may require.
  • By maximizing the number of parts per panel and by not putting phantom x-out requirements on the panels - FCT can provide cost effective circuit assembly solutions for our customers.
  • Further, our proven expertise in assembly on flex will lead to higher yields, again leading to improved savings for our customers.

We would welcome the opportunity of taking your circuit further by supporting you with our EMS/Assembly services!  

Product Module to Complete Product Box Build Services

Our customers continue to demand more and FCT has responded to where today we provide customers with added service in delivering Product Module Builds to Complete Box Builds.   It was a natural step for us given we were often producing an assembly that would be at the heart of a Product Module or in cases of the overall Product or Device. 

For Product Module builds most often this includes taking the circuit assembly and providing additional value-added assembly, it could be that we are attaching it to a plastic carrier or metal component.  It could be that we are adding an additional component or wire harness and then shipping the product module to our customer for input into the OEM's final product.  

For Complete Product Box Builds, FCT is literally taking on the entire product program for our customer.  Most often this includes producing and testing the circuit/assembly that is at the core of the overall product.  From there we then are utilizing our plastic groups to produce a housing and carriers if needed, and then will source any additional components with ISO approved sub-suppliers. 

FCT also takes on Medical related programs that require FDA product registration.  To meet FDA requirements, FCT must have robust quality systems in place and further must be able to meet the stringent traceability requirements that these program demand. 

FCT Box Build Services include:

  • Core electronics – Flex/Rigid Flex/Flexible Heater/Membrane Switch and full Assemblies
  • Testing Services for circuit assemblies
  • Sub-Level Product Assembly, Product Module Builds and Testing
  • Sourcing of specialized materials and/or components
  • Complete Product Assembly
  • Software Loading and Product Configuration
  • Final Product Testing Services
  • Documentation Inclusion and traceability requirements
  • Packaging and Labeling
  • Warehousing and Shipping
  • Overall Program Management

FCT has performed Product Module/Complete Box Build services for start-ups, to mid-sized growth companies, to top tier global OEMs in the differing markets that we support.
