🎨Common Mistakes in PCB Design
✔Irregular Pad Design‌
It includes incorrect pad size, too large or too small pad spacing, asymmetric pads etc. These problems may cause poor soldering, displacement, tombstones, etc. during welding.
✔Mark Point Design is not Standardized
Mark points are used for machine recognition. If the design is not standardized or missing, it will cause difficulty in machine recognition.
✔Insufficient Test Point Design‌
Insufficient test points will make fault diagnosis difficult. Necessary test points and debugging interfaces should be included in the design.
✔Insufficient Mechanical Design
Insufficient mechanical strength of the PCB may cause damage during assembly or use. The thickness, material and support structure of the board need to be considered to improve mechanical stability.
✔Characters are Placed Randomly
Improper character design or characters covering the pads, will cause inconvenience to the continuity test of the printed circuit board and the welding of components.
✔Ignoring Electromagnetic Compatibility (EMC)
Designing without considering EMC may cause the product to fail radiation and immunity tests. Shielding, grounding and filtering techniques should be used to reduce the impact of EMI.
✔Failure to Consider Manufacturing Limitations‌
Failure to consider manufacturing capabilities during design may lead to production difficulties or increased costs. It is critical to understand the manufacturer's capabilities and communicate them in the early stages of the design.

stands for "Ball Grid Array," and PCB stands for "Printed Circuit Board." A BGA PCB is a type of circuit board that uses ball grid array technology for the attachment of integrated circuits (ICs) and other components.
In a , the ICs are mounted on the surface of the board, and the electrical connections are made by tiny balls of solder that are attached to the bottom of the ICs. These balls are then placed onto a grid of pads on the surface of the PCB, and the solder is melted to create a strong, permanent connection.
One of the biggest advantages of BGA PCBs is their high-density circuitry. BGA technology allows for more efficient use of board space, which is essential for smaller devices such as mobile phones, laptops, and wearables. In addition, BGA PCBs can handle higher power levels and offer improved heat dissipation compared to traditional PCBs. This makes them ideal for high-performance applications that require fast data transfer rates and minimal heat buildup.
Another advantage of BGA PCBs is their reliability. BGA connections are less likely to fail due to their high-quality solder joints, which can withstand temperature changes and vibrations without breaking. This makes BGA PCBs ideal for applications that require high durability, such as aerospace and military applications.
As electronic devices continue to become smaller, faster, and more powerful, BGA PCBs will play an increasingly important role in the development of electronics.

TPCB (Transparent Printed Circuit Board) is a circuit board made of special transparent materials, which has high transparency and good electrical properties.
Common transparent substrates include polyester film (PET), polycarbonate (PC) and polyimide film.
Feature
✔High transparency
The transparency of transparent circuit boards is usually more than 90%, which allows light to pe*****te and provides more visual possibilities for product design.
✔Good electrical performance
While maintaining transparency, transparent circuit boards also have good conductivity and signal transmission capabilities to meet the functional requirements of electronic products.
✔Flexible and bendable
Some transparent circuit boards are made of flexible materials and can be bent and folded as needed, suitable for applications in various special shapes and spaces.
✔High temperature resistant, waterproof and dustproof
Transparent circuit boards can withstand high temperatures and have waterproof and dustproof properties, suitable for use in harsh environments.
✔Good stability
Transparent circuit boards have good chemical stability and thermal stability, can prevent oxidation and aging, and extend service life.

Sometimes there is incorrect component applied in the BOM, when find it after testing, will check with client and replace it.
For saving time and cost, the BOM also plays an important role.

The UL 94V-0 is a flame-retardant standard that evaluates the flammability of materials used in electrical devices.
UL 94V0 is more than just a code, it's a standard that sets your electronics apart. In simple terms, it signifies that a circuit board meets the UL 94V-0 flame-retardant rating, ensuring safety, durability, and high performance. When your Circuit Boards bear the 94V0 mark, customers know they're investing in quality.
