1.What Is The Meaning of CCA Manufacturing?    

CCA is short for Circuit Card Assembly, which is widely used in electronics. As a matter of fact, the CCA is the same as the frequently expression of Printed Circuit Board Assembly (PCBA), which means that the factory will assemble the components to the naked PCB according to the customers’ designing file in order to make the PCBA realize the expected functions in in the actual applications.

2.What Will Be Included for CCA Manufacturing?    

(1) Circuit Card Design: No matter what products are, the design is the initial step and foundation, and the PCB is no exception. Firstly the customers tell the requirements to the engineers, and then engineers make the lay-out as requests and source the components. The most important for engineers are Gerber files and BOM (Bill of Materials), which can increase the efficiency.
(2) Purchasing Components: The manufacturer will purchase the related components listed from the BOM which offered by the customers
(3) Naked Circuit Card Production: In order to turn the design into the product, first of all, we need to manufacturing the PCB which facilitates the assembly of components. The circuit card manufacturing steps are the following:
A. Base Material Picking-out: The PCB materials are including Fr4, aluminum, HDI, etc, and choose the suitable material for customers’ needs.
B. Photoresist and photomask: Apply photoresist on the copper layer, and expose and develop through the photomask.
C.Etching: In order to have a conductive track, etching away the unprotected copper layer is required
D.Drilling: Making holes on the circuit board for components through
E.Electroplating: This step is guaranteeing the electrical connection
F.Solder mask coating and screen printing: To prevent short circuit, solder mask is necessary, and print component position identification
G.Test: Using different tests on the bare board to ensure the quality

3.CCA manufacturing process:

(1)Components Preparations according to the BOM
(2)SMT machine for template and bare PCB
(3)Soldering paste application
(4)Soldering-reflow for melting and fixing the components
(5)Testing on Visual, AOI, AXI, ICT, Function, etc.

Conclusion

CCA Manufacturing is one-stop service including design, component sourcing, PCB manufacturing, PCB assembly and final testing, which guarantees 100% quality though strict control and testing. Nowadays the CCA Manufacturing is developing fast and widely applied in the electronic products.
