Flex Box Controllers

There is a significant volume opportunity to remanufacture this design of control unit.
Determine a process to open an ECU housing designed to not be opened.
Open the flexed printed circuit board without breaking the board or solder connections.
Develop a ruggedized reman process for the product.

After the reman process, the unit must function as good as a new unit.
The PCBA must be flexed closed without damage after repairs.
The ECU must be air tight to customer specifications.
The end result needs to be a cost effective reliable alternative to new.
Discover failure modes through extensive testing, hot , cold, and room temperature.

We determined a process to cut open the housing to gain access to the PCBA.
There is a maximum angle the PCBA can be opened without damage to the board itself.
A block was designed to keep the board from flexing beyond or below a specified angle. Ciona has determined that the flex circuit board within the flex box can be damaged by over-flexing or multiple flexes, much like any wire so we have elected to only a unit to be opened and closed one time to reduce the risk of damage to the board.
A primary failure was discovered and the OEM notified for future production.
New internal housings are utilized and provide the best opportunity to meet the air pressure specification.

This process covers a broad range of part numbers and applications from Agriculture, Marine, and Construction.
Discovered failures from testing reported back to the OEM.
A ruggedized remanufactured product is designed to minimize downtime and provide the customer a lower cost repair alternative.
