CAD/CAM
After designing pattern of inner/outer layer
processing DATA with considering working conditions.
|
|
 |
| |
|
SHEARING
It is a shearing process to cut the raw copper plates
in a desired panel size.
in this process step,We carefully control the raw
copper plate
in order to remove the defect sources due to scratch,pressing,
and spearing that may result in a substantial defects
in back-end processes |
|
|
| |
|
IMAGING(inner layer)
Improving adhesive of LPR due to
Forming roughness. |
|
|
| |
|
ETCHING(inner layer)
Development : dissolving except hardened parts
by exposing to UV.
Corrosion : Removing disclosed copper foil
that isn’t forming pattern.
Peeling : Peeling off D/F resist that complete
its part as anti-corrosion foil. |
|
|
| |
|
INSPECTION(inner layer)
Inspection image conditiom of
inner layer with optical method and
facilitios. |
|
|
| |
|
OXIDE
Process of surface to improve
adhesiveness between each layer
during pressing. |
|
|
| |
|
LAY UP/LAMINATION
To produce MLB, heating and putting pressure
on previously stacked product to form inner/outter
layer
and MASS-LAM which is stable hardened state. |
|
|
| |
|
DRILL
As being equiooed automatic input loader,
it does not necessary to have a period for
changing process. |
|
|
| |
|
PLATING
A process making connections between conductor layers
forming solderbility inside hole by plaing copper
after drilling porcess. |
|
|
| |
|
IMAGING(out layer)
Expose resist that is sprayed on or stuck to the
surface
of a copper foil to UV to polynerize and
to form patterns that are wanted. |
|
|
| |
|
ETCHING(out layer)
Development : dissolving except hardened parts by
exposing to UV.
Corrosion : Removing disclosed copper foil
that isn’t forming pattern.
Peeling : Peeling off D/F resist that complete
its part as anti-corrosion foil. |
|
|
| |
|
INSPECTION(out layer)
Irradiating a pay to board to compare data given
for working with data got from irradiation
and to check problems. |
|
|
| |
|
SOLDER MASK
Before PSR printing forming special tone on board
to
Increase adhesiveness with PSR. |
|
|
| |
|
LEGEND
Print Symbol and lettering with invariable ink on
board. |
|
|
| |
|
FINLA FINISH
Immersion nikel & gold plating on the surface
of copper as a kind of
surface treatment. |
|
|
| |
|
ROUT
Processing produces according to shipping standard
or kit,
which is first throwed in as a unit of PNL. |
|
|
| |
|
ELECTRONICAL TESTING
Electrical connection test for a large quantity
of products by JIG. |
|
|
| |
|
FINAL VISUAL INSPECTION
Checking whether a finished product meets standard
requirements. (Surface) |
|
|
| |
|
OUT GOING INSPECTION
Inspecting finaly inspected products not to ship
in congruent
products to customers. |
|
|
| |
|
PACKING
Packing products with care not to be damaged for
shipping. |
