CIRCUIT BOARD MANUFACTURING
TURNKEY FLEX AND RIGID FLEX PCB PRODUCTION

Throughout our years of experience, Pioneer Circuits has been able to optimize our pcb manufacturing workflow. As a leading printed board manufacturer, we understand the importance of making sure everything runs smoothly while eliminating as much waste as possible. Each pcb manufacturer has their own version of a traveler that follows the board through each step of the manufacturing process, giving the technicians information on the part and what needs to be done. Pioneer Circuit’s pcb board manufacturing process is optimized by strategic organization by part number on our travelers. We continually adjust our travelers and workflow to make improvements, ensuring a smooth flow of our part from the beginning to end of the manufacturing process.
STEPS TO

PCB MANUFACTURING & BOARD MANUFACTURER


ENGINEERING
Our manufacturing process begins with our Engineering department. Our customer designs are checked for manufacturability, and the documentation and travelers for our boards are created. These travelers follow the board and gives information about the board throughout the manufacturing process.
INNER-LAYER PROCESS
The board is then taken through the inner layer process in which it goes through chemical cleaning, coating, imaging, etching, drilling and lamination processes. Depending on the complexity of the board, it may need to go through these processes several different times.
OUTER-LAYER PROCESS
After all the inner layers are done, the board goes through the processes once more, beginning with the imaging department.
FINAL LAMINATION
Lamination is the process in which the layers of the board are laminated together. Once again, depending on the complexity of the board, it may pass through the lamination process multiple times until, finally, is put all together during final lamination.
ELECTRICAL TEST
The boards then go through electrical testing, where they are check to make sure that there are no problems with shorts. If there is, a report is printed out for the problems to be assessed and fixed.
INSPECTION
Before moving on the assembly process, the boards go through an inspection process in which Pioneer Circuits team members ensure the quality of the board. Customers may also request a source inspection to make sure their parts are up to standard before assembly.
CIRCUIT BOARD MANUFACTURING CAPABILITIES


EXTENDED LENGTH & OVERSIZE
Larger boards in the pcb industry typically range up to 22’ x 34’. At Pioneer Circuits, we have the ability to manufacture panels as large as 80” in length through our autoclave lamination. Furthermore, Pioneer Circuits’ extended length flex presents great design possibilities to our customers. When designing a larger project, engineers often run into the problem of having to connect multiple pwbs and connecting them together through different means such as bulky ribbon cables. Rather than having many wiring boards, cables and connectors that are all potential points of failures, Pioneer Circuit’s extended length flex replaces all of these components with a sleek and time saving solution that eliminates human errors in assembly and provides enough reliability for the harshest environments. Pioneer Circuits has produced extended length flex circuits that are up to 35 feet, and have the capability to go beyond this to fit your needs.


BOOKBINDER
Bookbinders are often the best or only way to achieve a tight bend radius with multiple flex layers. Pioneer Circuits’ long experience in the industry, along with our unique tooling and equipment modifications, have given us the ability to fabricate bookbinder designs without substantial costs or yield differences. Bookbinders are becoming more and more common in the printed wiring industry, but Pioneer Circuits specializes in the ability to create book binders with a much higher amount of flex layers. By staggering the length of each flex layer, we are able to greatly reduce the compression and tension forces that are introduced with flex layers are bent into its final configuration. Pioneer Circuits’ experienced staff in pre-production engineering calculates the appropriate staggers based on the customer’s final installed configuration.


MULTILAYER
Although high layer count boards are becoming more common, it is the ability to create multilayer boards with sub laminates that makes Pioneer Circuits unique. For more complex rigid flex configurations, many lamination processes are needed. Typically in the pcb industry, rigid flex wiring boards can have up to 5 sub laminates. Pioneer Circuits has the capability to manufacture multilayer rigid flex wiring boards with over 40 layers and 8 sub laminates.


CONSTANTAN
Constantan is a nickel-copper-alloy with thermo-characteristics that can be used in place of copper for applications such as infrared imaging. Pioneer Circuits has extensive experience with manufacturing pcbs with constantan, which is not typically utilized throughout the industry, because of its difficulty to be manufactured with. Our experience has led us to further constantan-related capabilities including Adhesiveless constantan laminates and controlled resistance via copper micro plating.
