Basic electronic components in PCBA board
At present, the country has higher and higher requirements for environmental protection and greater efforts in link governance. This is a challenge but also an opportunity for PCB factories. If PCB factories are determined to solve the problem of environmental pollution, then FPC flexible circuit board products can be at the forefront of the market, and PCB factories can get opportunities for further development.
The Internet era has broken the traditional marketing model, and a large number of resources have been gathered together to the greatest extent through the Internet, which has also accelerated the development speed of FPC flexible circuit boards, and then as the development speed accelerates, environmental problems will continue to appear in PCB factories. In front of you. However, with the development of the Internet, environmental protection and environmental informatization have also been developed by leaps and bounds. Environmental information data centers and green electronic procurement are gradually being applied to the actual production and operation fields.
As the basic electronic components in PCBA boards, transistors are widely used in various circuits. According to different countries, there are different naming standards for transistor models. Nowadays, there are three main industry standards for naming transistors.

1. Japanese Industrial Standards (JIS)
The JIS-C-7012 specification for transistor part numbers starts with "2S". 2SD965, but sometimes the "2S" prefix is not marked on the package. For example, 2SD965 may only be marked as "D965"; a 2SC1815 may be listed as "C1815" by the supplier. This series sometimes has a suffix (such as "R", "O", "BL", which stands for "red", "orange", "blue", etc.) to indicate variants, such as tighter hFE (gain) groupings.

2. European Electronic Component Manufacturers Association (EECA)
The Pro Electron standard is the European Electronic Component Manufacturers Association part numbering scheme, starting with two letters: the first gives the semiconductor type (germanium is A, silicon is B, and gallium arsenide is C). The second letter indicates the intended use (A is a diode, C is a general-purpose transistor, etc.). Below is a 3-digit serial number (or a letter and then a 2-digit number for industrial types). With earlier equipment, this indicates the type of case. Letters can be used, such as "C" for high hFE, for example: BC549C or other codes may show gain (for example, BC327-25) or rated voltage (for example, BUK854-800A).

3. Joint Electronic Equipment Engineering Council (JEDEC)
JEDEC EIA370 transistor device numbers usually start with "2N", indicating three-terminal devices (double-gate field effect transistors are four-terminal devices, so start with 3N), and then the 2, 3 or 4-digit serial number has no meaning for device properties ( Although early devices with low numbers tended to be germanium). For example, 2N3055 is a silicon n-p-n power transistor, and 2N1301 is a p-n-p germanium switching transistor. Letter suffixes (such as "A") are sometimes used to indicate newer variants, but groupings are rarely obtained. Over the years, we are proud to maintain a 99% on-time delivery rate.
