OM TRADING IS ESTABLISHED WITH A OBJECTIVE TO CATER THE DOMESTIC MARKET WITH GOOD QUALITY COPPER CLAD LAMINATE AS PER THE DEMAND OF THE CUSTOMER . THE COMPANY HAVING EXPERIENCED PROFESSIONAL FROM PCB AND COPPER CLAD LAMINATE HAS THE CAPACITY TO EVALUATE THE QUALITY AND PROCESS REQUIRED IN THE BOARD . THE FOREMOST DISTINNGUISH THING IS THE QUALITY OF PRODUCT SELECTED AND TIMELY DELIVERY TO VALUED CUSTOMERS , SO THEY CAN RELY ON THE SUPPLY OF MATERIAL AS PER THEIR DEMAND.
WITH THE DIVERSIFIED DEMAND IN THE INDIAN MARKET WE DISCUSS VARIOUS PARAMETERS WITH THE CUSTOMER AND ALSO SUPPLY AS PER THE SPECIFIC REQUIREMENTS . IN SHORT FACILITY FOR TELLER MAKE OF CCL IS OFFERED BY US . WE DEAL IN CCL , UNCLAD , METAL CLAD.
CCL is also known as substrate.
The reinforcing material is impregnated with resin, coated with copper foil on one or both sides, and a plate-like material made by hot pressing is called copper clad laminate (CCL). It is the basicmaterial to do PCB, often called the substrate. When it is used for multi-layer board production, also known as core board (core).
For CCL type, often according to different rules, there are different categories:
Mechanical rigidity of CCL: rigid CCL (FR-4, CEM-1, etc.) and flexible CCL (FCCL, FPC, etc.). (FR-4, CEM-3, etc.), metal-based CCL (aluminium plate, etc.), ceramic-based CCL (ceramic-based), according to different insulation materials and structure.
According to the thickness of copper cladding: divided into conventional and thin plate.
5mmConventional plate thickness ≥ 0.5mm
Thin plate thickness < 0.5mm (excluding copper foil thickness)
In accordance with UL standards (UL94, UL746E, etc.) flame retardant grades are non-flame
retardant Type (HB, etc.) and flame retardant CCL (FR-4, CEM-1, FR-1, CEM-3) and
According to some special performance of CCL:
Such as: high Tg plate (Tg> 170 ℃), medium Tg plate (Tg> 150 ℃), high dielectricity,High Dk, High CTI Plate, Low Thermal Expansion Coefficient Plate (Low CTE), Halogen-free plate (HF) and
so on. The composition of CCL
Production technology process of FR - 4 copper clad laminate
CCL performance and standardCCL performance requirements can be summarized as the following six aspects.metal foil surface pits, scratches, resin, fold, pinhole, bubbles, white wire, etc.
Size requirementSuch as: length, width, diagonal deviation, warping, etc.
Electrical performance requirementsIncluding the dielectric constant (Dk), dielectric loss tangent (Df), volume resistance, surfaceresistance, insulation resistance, arc resistance, dielectric breakdown voltage, electrical strength, compared to the tracking index (CTI), ion Migration (CAF) and so on.
Physical performance requirementsIncluding: dimensional stability, peel strength (PS), bending strength, heat resistance (thermalstress, Td, T260, T288, T300), punching, etc.
Chemical performance requirementsIncluding: flammability, weldability, chemical resistance, glass transition temperature (Tg), Z-axisthermal expansion coefficient (Z-CTE), dimensional stability and so on.
Environmental performance requirementsInclude: water imbibition, pressure vessels cooking test, etc.
