leadership, total employee participation,
customer-driven quality, management by fact, and
continuous improvement.
PACKAGING AND LABELING STANDARDS
Packaging and labeling standards have been established
for specific device types to prevent mechanical (bent
leads, chipped bodies, etc.), ESD, and solderability
damage as well as to clearly identify the product
throughout processing. These standards are summarized below:
- Innermost Packaging - Antistatic tubes, foam, or JEDEC trays. Product in tubes must all be oriented the
same way and must not be loose in the tube. If the
product cannot be placed in a tube, then it may be
cushioned with antistatic foam to prevent lead damage or
placed in a custom designed JEDEC tray in which the
devices are held in place by another JEDEC tray.
- Intermediate Packaging - Product in tubes must be
placed in static-shielding bags. An ESD caution label
and a pick ticket must be adhered to the intermediate
package.
- Outermost Packaging - Intermediate packages for an
entire order must be cushioned with environmentally safe
filler material when placed in the shipping container.
Note: Product will be kept in manufacturer's original
standard packaging whenever possible, since reduced
handling decreases the likelihood of product damage.
All moisture-sensitive product is packaged in dry
pack packaging, which includes a moisture barrier bag,
desiccant, humidity indicator card, and special labels
according to manufacturer and industry specifications.
PACKING AND SHIPPING
All orders are checked for part identity, packaging, and
documentation. Proper ESD protective packaging and
labeling is prepared in accordance with the Global Source Technology
packaging and labeling standards.
A computer-controlled order consolidation process is
used before the product is sent to packing. Bar code
scans ensure that all picks are properly consolidated
before being sent to the predetermined packing stations.
The computer system will not allow the order to be
processed unless a second bar code scan is performed
ensuring that all items are present and that there is no
mixing of items in the order. Military products are
packaged with proper documentation.
INSPECTION PROCESS
Inspections are performed by Quality personnel on an
audit basis at pre-determined points (Receiving,
In-process, Final) in the process flow. The sample size
selected is based on SPC data and can only be adjusted
by the Quality Manager.
RECEIVING INSPECTION
In value-added operations (Assembly, Programming,
Kitting, Computer Integration) there can be more
in-process inspection points due to the complexity of
the process flow.
A documented system and separate area exist for
receiving inspection. Inspectors inspect to written
instructions, including up-to-date prints and
specifications, where applicable.
There is no functional (electrical) inspection. One
hundred percent of all incoming receipts are visually
inspected at receiving inspection for identity, count,
packaging, condition, and documentation. A more in-depth
physical inspection is performed on a sampling of
incoming supplier receipts based on supplier historical
performance. MIL-Std-105 sampling plans are used.
Receiving inspection data is collected and used for
statistical process control. The data is also sorted by
supplier and used to prepare a supplier rating report.
Inspection for a particular supplier may be loosened or
tightened based on the supplier rating.
Accepted material is clearly identified and sent to
stock. Rejected material is also clearly identified and
placed in a segregated "defective" location to prevent
use before being dispositioned.
IN-PROCESS INSPECTION
Pre-determined in-process inspection points are set up
after the receiving, storing, and picking processes.
This inspection is performed by an in-process inspector
or auditor who collects the data and uses it for
statistical process control. The purpose of the
in-process inspection is to further pinpoint problems
with the system that need correction and also to
identify errors earlier in the process.
The receiving, storing, and picking operators have
also been trained to perform their own in-process
inspections before they perform their normal tasks. The
procedure requires them to verify part number,
packaging, and documentation before continuing their
work.
When an error is identified, a reject ticket and a
data collection form are completed. The rejected
material is identified by the reject ticket and
segregated. The errors are corrected by the operator at
the previous operation and corrective action is
annotated on the reject ticket. The corrected items are
then re-inspected.
FINAL INSPECTION
A documented system is in place in accordance with
MIL-I-45208. Inspection is performed by trained
inspectors who have not performed the work. A detailed
inspection is performed on outgoing orders using a
checklist for both picking and packing inspection
criteria. Some criteria are inspected 100 percent and
others are inspected in accordance with MIL-STD-105.
Although a random sampling of outgoing orders is
generally chosen for final inspection, the QA Manager
may determine that 100 percent inspection is warranted.
The loosening/tightening of the sampling plan is the
responsibility of the QA Manager. The data collected at
final inspection is used for statistical process control
and quality reporting.
All special handling orders are inspected 100 percent
for the special customer requirements in addition to the
normal inspection criteria.
Rejected material is identified, documented, and
segregated. Items are then corrected by the pick/pack
operator and re-inspected.
NON-CONFORMING MATERIAL CONTROL
A documented system exists which outlines how
non-conforming material is dispositioned and how
discrepancies are resolved.
Non-conforming material is identified and segregated
to prevent mixing or use. Disposition of receiving
inspection discrepancies is the responsibility of the
Product Manager. The Product Manager must work through
the franchised supplier and QA to resolve the
discrepancy. Final inspection discrepancies are resolved
through definitive procedures and supervisory
involvement. The ability to pinpoint errors through
operator accountability and SPC data aids in the
corrective action process.
CUSTOMER RETURNS
All customer returns are sent by the customer to
designated Return Centers and are inspected 100 percent
for identity, count, packaging, damage, documentation,
and reason for return. All returns are dispositioned
within 24 hours. Credit data is captured and used for
quality and cost of quality measurements.
ESD CONTROL
A documented system to prevent Electro Static
Discharge
(ESD) damage to devices exists. This control system is in compliance with EIA-625 and
includes:
- ESD warning signs displayed
- ESD-protective apparel: heel and wrist straps, smocks
- ESD-protective equipment: conductive flooring,
static-dissipating work surfaces or mats, grounded
equipment
- ESD-protective packaging: static shielding bags,
conductive totes
- ESD work area kept clear of all unnecessary static
hazards
- All operators handling parts out of ESD-protective
packaging do so only at a static-free workstation. The
operators also wear gloves to prevent inducing soldering
problems onto the leads of the parts. ESD-sensitive
product is always transported in static-shielding bags
or conductive packaging.
- ESD training is given to all operators, who are
ESD-certified for one year. The ESD coordinator, who
monitors heel and wrist strap effectiveness and
ESD-awareness operator discipline, performs the ESD
audits. These records are kept on file. Corrective
action is taken when needed to enforce ESD rules.
SPECIAL CUSTOMER HANDLING
Customer orders with special requirements, such as
selective date codes, special packaging and labeling,
bar code labels, etc., are processed through Global Source Technology's
special handling system. Customers set up on special
handling are assigned a three-digit code to each
applicable account number.
All special handling orders are automatically
diverted off of the conveyor system into the special
handling area, where trained operators perform the
necessary operations and/or verifications per the
special handling instructions. Special handling
instructions are prepared and controlled by the Quality
Department.
QUALITY REPORTING
Global Source Technology uses a variety of quality measurement systems in
all areas of the company, especially in the warehouses
and value-added centers.
Global Source Technology uses a variety of quality measurement systems in
all areas of the company, especially in the warehouses
and value-added centers. "Internal" measures include
Statistical Process Control of non-conforming material
identified during audit processes, inventory accuracy,
and same-day shipment percentage. "External" or
customer-reported measures include Field Quality
Reports, customer returns, on-time delivery, cost of
quality, and customer satisfaction surveys. Supplier
quality and on-time delivery performance is monitored on
the Supplier Rating System.
Quality and service statistics and trends are
summarized and distributed to all levels of management
on a quarterly basis.
FIELD QUALITY REPORTS
Any quality problem communicated to a field location by
a customer is reported on a Field Quality Report (FQR).
FQRs are available on email and are electronically
transferred to the shipping location and Quality
Department. All FQRs are logged and analyzed for problem
root cause. A response is sent to the FQR initiator. If
the customer requires a response, then it is the Quality
Manager that responds to the customer. Overall FQR data
are analyzed and trended to continually improve efforts.
SUPPLIER RATING SYSTEM
Supplier performance is tracked and analyzed through
Global Source Technology's Supplier Rating System (SRS). The SRS rates
suppliers on both quality and delivery performance.
Suppliers are measured on lot acceptance at receiving
inspection, on-time delivery, and defective line items
shipped to customers. This data is provided to suppliers
and is used to identify problem areas and track
improvement efforts.
Supplier Corrective Action Reports (SCARs) requesting
cause and corrective action are issued to suppliers for
poor performance or for recurring receiving errors.
CORRECTIVE ACTION SYSTEMS
There are various types of formal corrective action that
must be implemented in order to continuously improve the
quality systems. These corrective actions include:
- Customer corrective actions - formal responses to
customers on orders in which their requirements were not
fully met. These may be thought of as customer
complaints.
- Internal corrective actions - generated by the quality
department and sent to another department requesting a
written response. ICARs may be used for corrective
actions on FQRs or SPC data.
- Internal audit corrective actions - issued to facility
management based on internal audits in order to ensure
that facility quality systems are in compliance with
Global Source Technology quality policies and ISO 9002.
- Supplier corrective actions - issued to both
franchised suppliers and subcontractors based on
supplier rating system data and customer complaints, if
applicable. SCARs are used to improve supplier
performance.
- Management review/quality report corrective actions -
summaries of actions taken and status of quality
objectives and plans from management review meeting and
of recurring quality problems documented in quality
review report.
The typical processes involved in implementing
corrective actions are:
- Analyze entire process, including quality records and
customer complaints in order to pinpoint problem area
- Investigate root cause of problem. Root cause
generally must be process-related rather than
operator-related
- Initiate corrective action to process to prevent
recurrence of problem.
