PCB新聞 - PCB元件庫命名規則

1. Integrated circuit (in-line)
   Use DIP-pin number + suffix to indicate dual in-line package
   There are two suffixes, N和W, to indicate the body width of the device
   N is a narrow package with a body width of 300mil 和 a pin pitch of 2.54mm
   W is the package with body width, 車身寬度為600mil, 銷間距為2.54mm
   For example: DIP-16N represents a 16-pin narrow dual-in-line package with a body width of 300mil and a pin pitch of 2.54mm

2. 集成電路板 circuit (SMD)
Use SO-pin number + suffix to indicate small outline SMD package
There are three suffixes of N, M and W to indicate the body width of the device
N is a narrow package with a body width of 150mil and a pin pitch of 1.27mm
M is a package between N and W, 機身寬度為208mil，引脚間距為1.27mm
W is the package with body width, 車身寬度為300mil, 銷間距為1.27mm
For example: SO-16N represents a 16-pin small-outline chip package with a body width of 150mil and a pin pitch of 1.27mm
If SO is preceded by M, 這意味著它是一個微型封裝，主體寬度為118mil，引脚間距為0.65mm

3. Resistance
3.1 The naming method for SMD chip resistors is: package + R
Such as: 1812R represents a resistor package with a package size of 1812
3.2 The naming method for carbon film resistors is: R-package
For example: R-AXIAL0.6表示焊盤間距為0的電阻器封裝.6 inches
3.3 The naming method of cement resistance is: R-model
Such as: R-SQP5W represents a cement resistor package with a power of 5W

4. Capacitance
4.1 The naming method for non-polar capacitors and tantalum capacitors is: package + C
Such as: 6032C means that the package is 6032 capacitor package
4.2 The naming method of SMT monolithic capacitors is: RAD + pin spacing
For example: RAD0.2 means SMT monolithic capacitor package with a pin pitch of 200mil
4.3 The naming method of electrolytic capacitors is: RB+pin spacing/outer diameter
For example: RB.2/.4 means an electrolytic capacitor package with a pin pitch of 200mil and an outer diameter of 400mil

5. Diode rectifier device
The naming method is based on the actual package of the component, where BAT54 and 1N4148 are packaged as 1N4148

6. Transistor
The naming method is based on the actual package of the component. 將Q添加到SOT-23Q封裝中，以區分集成電路的SOT-23封裝. 其他場效應電晶體使用組件名稱作為封裝名稱，以便在不出錯的情况下調用組件.

7, crystal oscillator
HC-49S, HC-49U是表面貼裝封裝, 26歲, AT38為圓柱形包裝, and the size of the digital meter
For example: AT26 represents a cylindrical package with an outer diameter of 2mm and a length of 8mm

8. Inductance and transformer parts
Inductive sealing package adopts TDK company package

9. Optoelectronic devices
9.1 The naming method of SMD LED is package + D to indicate
Such as: 0805D means light-emitting diode packaged as 0805
9.2 In-line light-emitting diodes are expressed as LED-outer diameter
For example, LED-5 represents a direct plug-in light-emitting diode with an outer diameter of 5mm
9.3 The nixie tube uses the device's own name naming

10. Plug
10.1 SIP + number of pins + pin spacing to indicate a single row of pins, 銷間距有兩種：2mm, 2.54mm
For example: SIP7-2.54指銷間距為2的7針單列銷.54mm
10.2 DIP + number of pins + pin spacing to indicate double row of pins, 銷間距有兩種：2mm, 2.54mm
For example: DIP10-2.54表示10針雙排銷，銷間距為2.54mm

The above is an introduction to the naming rules of PCB component libraries. Ipcb也提供給 PCB製造商 and PCB製造 科技.
