Specializing in Prototype single, multi-layer flexible and rigid circuit boards for low to medium volume production. Five (5) SMT Lines with best-in-class Juki machines means high quality, high speed and quick turnaround services.
Expect speed, quality and a uniquely responsive customer service.
Production Line Capabilities:
Each SMT line is comprised of Juki or Ekra surface mount screen printer to precisely screen solder paste through the stencil or screen and accurately apply the solder paste to each PCB.
This automated process includes an automated 3D inspection system to assures each PCB has accurately applied solder paste before proceeding to the next machine in the SMT line.
Each SMT production line has a minimum of 4 Juki SMT pick-and-place machines designed to precisely place electronic components onto printed circuit boards (PCBs) during the assembly process.
Juki SMT pick-and-place are known for their high accuracy and precision. They can place a wide range of components, from tiny resistors and capacitors to large integrated circuits, on designated spots on the PCB with pinpoint precision.
Green Circuits is known for a large number of pre-configured trolleys to provide quick change over and rapid assembly of components onto the PCB.
The new iCoat-5 JetSelect Ultra High Precision Conformal Coating Machine from Anda Technologies provides capabilities for PCB coating requirements of many industrial and outdoor applications.
Each SMT line has a 10-flow, nitrogen reflow Heller 1810 oven to solder joints. Each board will flow through the oven for 10-12 minutes through 10 heating and 1 cooling to complete the process of converting from molten to hard solder joints.
For customers with low volume through-hole components, Green Circuits offers the capability for hand solder by highly skilled and experienced technicians.
Green Circuits has 3 Juki 460 Selective Solder Machines for high volume through-hole PCB. This offers precision and selective soldering of PCB’s for specific points or components using programmable solder profiles for high precision, flexibility and reduced thermal stress.
Each PCB is handled by a QC inspection station where a technician can view the solder quality.
The technician uses customer drawings, bill of materials and specifications to assure accuracy as the 1st stage of Green Circuits Quality Control Program.
Automated Optical Inspection (AOI) serves as a critical step in the Green Circuits assembly process, assuring the quality and precision in the PCB assembly line. This uses high-resolution cameras to thoroughly scan the surface of PCBs, identifying any defects such as soldering errors, missing components, or misalignments.
The AOI process is vital in Green Circuits' quality inspection capabilities by confirming that the placement and soldering of each component meet strict quality standards, thereby greatly reducing the likelihood of PCB failures.
Green Circuits production line includes Nordson DAGE XD7600NT Ruby X-Ray Inspection Machines as a critical role in the quality assurance process. Skilled inspectors can look deep into the heart of the circuit board to spot soldering errors, misalignments, and hidden issues with unmatched clarity.
This equipment ensures our PCBs not only meet but exceed quality and reliability standards, crucial for complex electronic devices. Its role in our lead-free soldering process is pivotal, safeguarding every solder joint and component. By integrating the XD7600NT Ruby, Green Circuits continues to lead the pack in producing flawless PCBs, ready for any high-stakes application.
Green Circuits’ production lines includes inline cleaning systems use specially formulated solutions to remove flux residues, contaminants, and soldering byproducts, ensuring each circuit board is pristine before moving on to the next phase of assembly.
This not only enhances the electrical functionality and longevity of the PCB but also prevents potential issues that could arise from impurities. By incorporating advanced wash machines into our production line, we guarantee a level of cleanliness that meets the highest industry standards, contributing significantly to the overall quality and reliability of our electronic devices. This commitment to excellence through cleanliness is a testament to our dedication to delivering superior products every time.
Green Circuits has 3 (single and double sided) flying probe machines for precise electrical testing. These flying probe testing machine are a crucial tool in the PCB assembly, designed to test boards' electrical functionality efficiently without the need for custom fixtures.
Utilizing movable probes, it swiftly checks connectivity, identifies defects, and assesses component values directly on the PCB. Its flexibility makes it ideal for prototypes and low-volume productions, offering a cost-effective solution for ensuring quality.
With the capability to access tight spots and perform detailed inspections, flying probe testers are essential for verifying the precision and reliability of PCBs, especially in complex designs, ensuring each board meets high standards before advancing in the production process or reaching customers.
Each PCB board is hand-inspected and tested for quality before being packed and shipped to the customer.
Green Circuits quality control inspectors are IPC trained and certified.
Today’s circuit boards are more complex than ever and the need for circuit board repair and rework is a given. BGA rework is one of the most difficult procedures at assembly facilities. Doing it right depends on the skills and knowledge of the rework technician, along with having the right equipment.
With 30+ years of experience in printed circuit board fabrication, assembly and rework, and state-of-the art equipment, Green Circuits’ rework technicians use the proper materials and methods to troubleshoot, diagnose, and rework a wide variety of issues.
For customers that require a complete assembly of the product, Green Circuits offers custom built stations to assemble components from sub-assembly installation, cable assemblies, wiring harness, PCB’s insertion, software loading, product configuration, functional level testing, packaging & labeling and order fulfillment.
