1. Introduction for Electronic Printed Circuit Board
A printed circuit board is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called a "printing" circuit board.

3.Process for Electronic Printed Circuit Board
Opening ------ Inner layer ----- lamination----drilling---sinking copper----line--- diagram electric----etching-----resistance welding ---character----spray tin (or immersion gold)-锣 edge-v cut (part of the PCB is not needed)-----fly test----vacuum packaging
4. Characteristics for Electronic Printed Circuit Board
PCBs are becoming more widely used because they have many unique advantages, as outlined below.
Can be high density. For decades, the high density of printed boards has grown with the integration of integrated circuits and advances in mounting technology.
1.High reliability. Through a series of inspections, tests and aging tests, the PCB can be reliably operated for a long period of time (usually 20 years).
Designability. For the various performances of PCB (electrical, physical, chemical, mechanical, etc.), the design of printed boards can be realized through design standardization and standardization, with short time and high efficiency.
2.Productivity. With modern management, it can standardize, scale (quantify), automate and other production, and ensure product quality consistency.
3.Testability. Established relatively complete test methods, test standards, various test equipment and instruments to detect and identify PCB product qualification and service life.
4. Assemblyability. PCB products not only facilitate the standardized assembly of various components, but also can be automated, large-scale mass production. At the same time, the PCB and various component assembly components can be assembled to form larger components and systems up to the complete machine.
5. Maintainability. Since PCB products and various component assembly components are produced in a standardized design and scale, these components are also standardized. Therefore, once the system fails, it can be replaced quickly, conveniently and flexibly, and the system can be quickly restored. Of course, you can say more about it. Such as miniaturization and weight reduction of the system, high-speed signal transmission, and the like.

Electronic printed circuit board (PCB) manufacturing processes:
PCB material choice:
Common base materials include FR-4 (fiberglass), polyimide and ceramics
Consider properties such as dielectric constant, thermal performance, and flexibility
Special materials available for high-frequency, high-power or flexible PCBs
Copper thickness and layer count:
Typical copper foil thickness ranges from 1oz to 4oz (35µm to 140µm)
Single-sided, double-sided and multilayer PCBs available
Additional copper layers improve power distribution, heat dissipation and signal integrity
Surface Treatment:
HASL (Hot Air Solder Leveling) - Affordable, but surface may not be flat
ENIG (Electroless Nickel Immersion Gold) – provides excellent solderability and corrosion resistance
Immersion Silver - Cost effective for lead-free soldering
Additional options include ENEPIG, OSP and direct gold plating
Advanced PCB Technologies:
Blind and Buried Vias for High Density Interconnects
Microvia Technology for Ultra-Fine Pitch and Miniaturization
Rigid-flex PCBs for applications that require flexibility
High frequencies and high speeds with controlled impedance pc
PCB manufacturing technology:
Subtractive process (most common) - etching away unwanted copper
Additive process - creating copper traces on the base material
Semi-additive process - combining subtractive and additive technologies
Design for Manufacturer (DFM):
Adherence to PCB design guidelines for reliable manufacturing
Considerations include trace width/spacing, via size and component location
Close collaboration between designers and manufacturers is essential
QA and testing:
Electrical testing (e.g., online testing, functional testing)
Mechanical testing (e.g., bending, shock, vibration)
Environmental testing (e.g., temperature, humidity, thermal cycles)
