As a contract electronics manufacturer of high-reliability and
mission-critical assemblies that are used in harsh environment
applications, Technical Manufacturing Corporation maintains a
comprehensive foreign object debris (FOD) program which identifies
and treats the facility as an awareness area. Our foreign object
debris program helps to ensure that foreign objects (FO) alien to
the product or process which can result in foreign object damage
is minimized and controlled to ensure that your high-reliability
products are guaranteed to perform as expected.
All operators are fully trained in the potentially damaging
effects of foreign object debris, which can include (but is
certainly not limited to) dust, debris, lead clippings, flux
residue, solder balls or splashes, electrostatic discharge,
moisture, fingerprints and other contaminants that can result in a
catastrophic field failure after installation by the end user or
reduce the mean-time-between-failure (MTBF) of the product. Where
applicable, operators wear powder-free nitrile gloves, finger cots
and electrostatic discharge safe smocks when handling product at
all times to prevent foreign object debris from originating from
the operator which can impact the reliability of the product.
Workstations where product is or can be processed always remain
free and clear at all times of all external items that are not
directly used in the production process to prevent exposure to
foreign object debris. All small hand tools, fixtures or other
production related devices are specifically assigned to each
operator for each sequence or operation step and documented upon
return for full accountability at all times. Shadowboxing is
employed at operator workstations which clearly identifies missing
tools or other production related items. Workstation areas are
protected by grounded electrostatic discharge safe mats coupled
with continuous zero-volt monitors to prevent the damaging effects
of electrostatic discharge as foreign object debris. In addition,
all workstations are equipped with Simco CenturION air ionizers.
McDry dry boxes are installed on both the production floor and in
the stockroom for the temporary storage of plastic encapsulated
moisture sensitive devices prior to use or application to protect
them from absorbing moisture which can result in their destruction
during the wave soldering or reflow processes.
Housekeeping is paramount to the success of any foreign object
debris program and at Technical Manufacturing Corporation this is
no exception. Operators are personally responsible for thoroughly
cleaning their own workstations and the surrounding areas upon the
completion of each operation step and at the end of their shift to
ensure that exposure to foreign object debris is eliminated.
Furthermore, the entire production floor is thoroughly vacuumed on
a nightly basis. No food or drink is allowed to be brought into
any area by an operator where product is or can be handled.

debris control program.
